General instructions •

Operation of and work on the equipment or parts thereof may only be performed by professional persons (qualified technicians) with appropriate experience who have been specially trained by the manufacturer/distributor (= authorized persons).

•

The weight of the components (specified on the front of the unit) requires that physically able-bodied persons be employed for installing / assembling the equipment or parts thereof.

•

If work on the equipment or parts thereof is necessary with the equipment under present voltage, another qualified technician or a supervisor must be present in addition to the electrician performing the work. The supervisor should be capable of providing first aid in case of electrical hazard. Providing the electrician with an emergency switch or disconnection strap, so-called "dead man's switch", is not sufficient protection.

•

Work on the equipment may only be carried out using insulated tools and appropriate protective clothing (shoes, gloves, safety spectacles, etc.).

•

There is an increased risk of an accident and electrical hazard when working on compact equipment (different components mounted in a single cabinet, e.g. rectifier/inverter modules, DC distribution and battery connection), due to the close proximity of the various different components. Work should therefore be carried out with extra attention to safety, and appropriate insulating covers over the live electrical parts must be provided for protection against accidental contact.

•

If the power supply equipment is not fitted with a disconnecting switch or equivalent device unit, for isolating it from the AC mains or any other hazardous voltage source, the operator of the power supply equipment is responsible for fitting the mains distribution board, battery system or other supplying equipment with appropriate disconnection switch conforming to the relevant regulations.

6 September 2007


3.2


•

The input filters of the rectifier/inverter modules are not protected with input fuses. The operator is responsible for ensuring adequate protection for the equipment and wiring by means of an input fuse, if any rectifier/inverter module is used external to equipment supplied by the manufacturer/distributor and if the manufacturer/distributor is not allowed install fusing or a main distribution board.

2.1


Operating modes In normal operation mode the rectifiers deliver the load power taken by the telecom system and simultaneously maintain the batteries at full charge. During a line power outage or an excessive line-undervoltage, the rectifiers are shut down and the batteries deliver the load power. If the battery voltage decreases below the preset level, the optional deep discharge prevention circuitry disconnects the battery automatically. As the line power is restored to a proper level, the rectifiers start up automatically and begin to deliver the load power and recharge the batteries at current limiting mode. The batteries are important components in a telecom power system. The control and monitoring unit is designed to ensure long battery life and effective recharging of the batteries. Automatic boost charge is based on battery current. The system level control and monitoring functions include local and remote alarms and local controls of the system. The local alarms are shown by alarm LEDs. Remote alarms are issued by means of potential free relay contacts. The operation of the control and monitoring unit is presented in the product description of the controller.

GENERAL The rectifier DPR 1200B-48 is a single phase, hot-pluggable, fan-cooled rectifier. The constant output power characteristic supplies the specified power over the full output voltage range. The benefit is an optimised modular system design (fewer modules) that matches the supply requirements of state-of-the-art telecom equipment. This performance as well as the extended temperature range, wide input voltage range, high power density and advanced technology are the key factors for the success of this rectifier, offering a cost effective and reliable solution. The typical applications for this rectifier are both in indoor and outdoor environments, which is a perfect solution for wireless base stations, core network components, telecommunications networks and data networks. The rectifier meets the requirements set by the telecommunications standards. The rectifier DPR 1200B-48 does not contain any user serviceable parts inside the unit and a faulty rectifier module should be replaced as a complete unit. The installation description must be strictly adhered to.

2.1

Safety The rectifier meets the safety standards: •

EN 60 950 (2000-06) - class 1

•

UL 60950 rev 3 (Dec1, 2000)

•

CAN/CSA-C22.2 No. 60950-00

No user serviceable parts are inside the unit. A faulty rectifier module should be replaced as a complete unit. The installation description must be strictly adhered to. The rectifier contains the following internal protection circuit breaker and fuses: AC input fuses F200 / F201 - 10AT LITTELFUSE INC. P/N 215010 BEL P/N 5HTP10 The protecting AC fuses are connected in L and N. DC output fuse F500 - 40A PUDENZ (WICKMANN GROUP) P/N 142.6185.5402 The protecting DC fuse is connected in – pole. These fuses are not accessible and should only be replaced in a Delta repair centre. Warning!

FUNCTIONAL DESCRIPTION The rectifier contains two stages of high frequency power converter: The power factor corrector (PFC) has a boost topology with a switching frequency of 120 kHz. It is responsible for the power factor and harmonic content of the input current. The DC-DC converter has a phase shifted full bridge topology with a switching frequency of 140 kHz. It is responsible for galvanic isolation and power conversion to the DC output. The control and interface circuit controls and protects the rectifier during all operation conditions appearing in a power system. The EMC filters guarantee the required standards.

Input voltage range If the input voltage exceeds the limits of the input voltage range the rectifier is shut off. The rectifier will restart automatically as soon as the input voltage returns into the specified input voltage range. At low input voltages, an output power derating is enabled to limit the input current to acceptable values. For AC mains voltage in the range of 276V to 300V, the power factor corrector (PFC) stage is self protecting and the input current shape is not sinusoidal. Pout / W 1200

Output voltage The factory setting is defined for flooded battery types: 53.5 V. If a controller with voltage programming function is used, it can remotely adjust the rectifier output voltage to different values via analogue signal interface or digital interface.

3.4

Output current The factory setting for the output current limit is 28 ADC.

3.5

Cooling The device is fan cooled. Warning! The air flow must not be restricted! Warning! Apply always blank panels for empty rectifier slots to avoid wrong air circulation inside the system!

3.6

Overvoltage protection OVP The rectifier is equipped with a selective over voltage protection, that shuts down the rectifier in case of output voltage exceeding an internally set limit. The protection is combined with a current measuring condition to achieve selectivity between parallel rectifiers; only the «guilty» rectifier will be shut down. The factory setting is 59 V. Reset of OVP shut down can be done by disconnecting the mains supply voltage for approx. 2 seconds.

GENERAL The rectifier FR 48 V - 2000 W - E is a single phase, hot-pluggable and fan-cooled rectifier. The constant output power characteristic supplies the specified power over the full output voltage range. The benefit is an optimized modular system design (fewer modules) and matches the supply requirements for state-of-the-art telecom equipment. This performance as well as the extended temperature range, wide input voltage range, high power density and advanced technology are the key factors of the success of this rectifier and it offers a cost effective and reliable solution. The typical applications for this rectifier are both in indoor and outdoor environments, which is a perfect solution for wireless base stations, core network components, telecommunications networks and data networks. The rectifier meets the requirements set by the telecommunications standards. The rectifier contains two stages of high frequency power converter (Figure 1.): •

The power factor corrector (PFC) has a boost topology with a switching frequency of 90 kHz. It is responsible for the power factor and harmonic content of the input current.

•

The DC-DC converter has a phase shifted full bridge topology with a switching frequency of 100 kHz. It is responsible for galvanic isolation and power conversion to the DC output.

The control and interface circuit controls and protects the rectifier during all operation conditions appearing in a power system. The EMC filters guarantee the required standards.

FUNCTIONAL DESCRIPTION

3.1

Input voltage range If the input voltage exceeds the limits of the input voltage range the rectifier is shut off. The rectifier will restart up automatically as soon as the input voltage returns into the specified input voltage range. At low input voltages, an output power derating is enabled to limit the input current to acceptable values. full power

Input voltage range

Inrush current limitation When the rectifier is first connected to the mains, the energy storage capacitors are charged via resistors. As soon as a certain voltage limit is reached, these resistors are short-circuited and the rectifier starts up and delivers output power.

3.3

Output characteristic The rectifier has a constant output power characteristic to meet the demand of optimal use of the power supply to electronic constant power loads. The result is a constant recharging current to the battery after a mains outage, and a better use of rectifier efficiency.

Output voltage The factory setting is defined for flooded battery types: 53.5 V. If a controller with voltage programming function is used, it can remotely adjust the rectifier output voltage to different values via analogue signal interface.

3.5

Output current The factory setting for the output current limit is 46.5 ADC.

3.6

Cooling The device is fan cooled. Note!

The airflow must not be restricted!

Overvoltage protection OVP The rectifier is equipped with a selective over voltage protection (OVP), which shuts down the rectifier in case of output voltage exceeding an internally set limit. The protection is combined with a current measuring condition to achieve selectivity between parallel rectifiers; only the «guilty» rectifier will be shut down. The factory setting is 59 V. Reset of OVP shut down can be done by disconnecting the mains supply voltage for a few seconds.

Reducing the output current in order to limit internal temperature.

The thermal management (protection sensor) protects the rectifier against interrupted air flow and fan failure. During these conditions, the rectifier is shut down as soon as the internal temperature reaches a critical value. After several unsuccessful restart attempts the rectifier remains shut down and generates an alarm.

3.9

Load sharing The rectifier is equipped with an active load sharing function that ensures equal load on parallel rectifiers. The function uses the signal interface bus between rectifiers. This function does not need any other external unit outside rectifiers.

3.10

Rectifier enable The rectifier is disabled / enabled by external connection: Disable: Pins D12 – A12 not connected Enable: Pins D12 – A12 connected

3.11

Precharge The rectifier module is hot-pluggable. Pushing the rectifier into the cabinet connects leading precharge contacts first to precharge the DC output capacitors. The remaining output power contacts are connected with a delay.

CONTROLLER PSC 3

This manual is created to instruct in the optimal use of the PSC 3 controller. The document is structured according to functions and answers to question “How to?”

2.2

Structure PSC 3 offers two operating interface types for the user; the web interface (web browser) and UIM interface. The UIM is located at the system and offers a quick access to basic settings and displays. The web interface is a complete configuration and supervision tool for the PSC 3. It requires cable between the PSC 3 module and a terminal (computer with a browser) either directly at the system or via network. This manual describes the essential PSC 3 functions and instructs how to enable and use them. The instructions are written for both user interface types under separate headings: «UIM Interface» and «WEB Interface».

CONTROLLER PSC 3

Introduction The PSC 3 is a sophisticated power system controller and therefore an optimum solution for small to very large and complex power systems. It consists of a central unit, which provides basic I/O periphery, and of a very robust and reliable CAN standard based communication bus (IMBUS), providing easy expansion. The front end modules are located close to the elements to be monitored. The benefit is an easy wiring, which is perfect for expandable power systems with decentralized distributions (BDFB) and batteries in separate rooms. The integrated PLC offers the flexibility for monitoring and control of auxiliary devices, later functions upgrade and system capacity expansions. The enhanced system functions support the reduction of operating costs. The battery management with regularly accomplished capacity tests is one of the key factors for the availability of a power system. The PSC 3 allows remote alarming by means of potential-free relay contacts or via modem or LAN / Ethernet. The SNMP functionality offers enhanced remote alarming and is designed to work with SNMP managers. An integrated web server offers a user friendly interface for detailed monitoring and control with a standard web browser. PSC 3 is a small device but can handle a large amount of peripherals. The appropriated functions are activated by configurable software and hardware addon's. The following figure shows the PSC 3 system concept:

UIM1 / UIL1 MENU UIL1 is the local user interface on the PSC 3 front; UIM1 is similar but decentralized, connected via IMBUS. In most applications, UIL1 meets all demands for local control, but in very large systems - and in order to keep compatibility to installations with PSC 3 SW Version ≤ 1.70 - the use of one or two UIM1’s is supported as well. There are some small differences between UIL1 and UIM1: UIL1

The back-light is locally controlled and is always on. The contrast is also locally controlled, you can change it by pressing EXIT and then ↑ or ↓ (EXIT should stay pressed) somewhere in the menu structure. In this mode the yellow COM LED is off and the UIM1 waits for the PSC 3 connection. If the PSC 3 is not connected or if the CAN communication is not ok, after 30 sec. «PSC 3 Connection Awaited» appears.

Simple Network Management Protocol (SNMP) Note!

The SNMP functionality is an option and does not come as default with the controller PSC 3. Please contact your local Delta representative for more information about the SNMP functionality.

5.2.2.1 Description Using Simple Network Management Protocol (SNMP) mainly performs monitoring of distributed network devices in heterogeneous networks. SNMP is the de facto standard for network management. For this standardised protocol many commercial off-the-shell (COTS) products are available, which range from simple alarm monitoring tools to powerful network management suites. Nowadays, alarm monitoring in DC power systems is usually performed using relay contacts. SNMP in DC power systems with PSC 3 offers new possibilities. The most important feature is remote monitoring using COTS applications and in case of an alarm e.g. notification via email or SMS. Furthermore, vital system parameters can be collected over a period of time to ensure system interoperability e.g. battery voltage or current. SNMP-based management system components are distributed throughout IP networks in the form of agents and managers. PSC 3 represents a SNMP agent entity, making DC power system parameters available to a SNMP manager entity. The PSC 3 controller, as agent, sends trap messages to the SNMP manager. PSC 3 controller is able to send traps to ten IP addresses (SNMP managers). In order for a SNMP manager to understand a trap sent to it by an agent, the manager must have the Management Information Base (MIB) for the specific traps loaded. For activating the SNMP functionality see also 13.4 Software License Key.

BATTERY The mission of the power system is to provide uninterruptible and quality power to the load. The batteries play a key role in the availability of the system, and the controller is vital for the battery management and supervision. PSC 3 offers a comprehensive set of battery management and supervision functions, such as different battery charge modes, temperature compensation, battery protection, battery testing and identifying possible weaknesses in battery strings. The following chapter describes the battery functions and instructs how to enable and use them.

6.1

Charging In normal mode, when AC supply of the power system is connected, available and meets the requirements, the rectifiers of the system supply power to the load and charge the batteries. If there are interruptions in the AC supply or for some reason the rectifiers are failing to supply part or all of the required power to the load, the batteries start to discharge and supply power to the load. When the AC supply and rectifiers return the controller will manage the rectifiers to supply power to the load and recharge the batteries. There are three different battery charge modes, which can be used in different states of the system: Float Charge, Equalize and Boost Charge. The battery manufacturer is responsible for providing the correct voltage levels and other battery charging information for the batteries.

6.1.1

Float Charge Battery float charge is the normal charge mode of the power system. The mode is managed by setting charge voltage for the rectifiers. The voltage is set in a level that compensates battery self-discharge. The temperature of the batteries has an impact on the charging and discharging of the battery. Therefore the temperature compensation function is used. Usually after a battery test, separate charge or a mains failure the system is in the recharge state. As soon as the battery is fully charged, the state changes to float. This state has no influence on the system voltage. For system voltage regulation the same parameters as in the float charge state are used. The recharge parameters, set with the float charge, define the criteria for the transition to float. Setting the float charge voltage and other related parameters are described below. Note!

Before setting the parameters, check the battery specifications and instructions of the battery manufacturer.

Equalize With flooded lead-acid batteries a function called Battery Equalize is available. Basically it means controlled overcharge of the batteries, during which normal charging is allowed to continue after the battery would normally be considered full, by using a higher charge voltage (> float charge voltage). This procedure equalises the voltages between battery cells and stirs up the fluids within batteries, extending the battery life. The PSC 3 controller offers a variety of parameters and settings which ensure that the procedure is carried out safely and within certain limitations. Note!

Figure 44. The battery string and rectifier arrangement for separate charge. There are two types of separate charge in the PSC 3: manual and semi-automatic. With the manual separate charge and discharge the separated battery is fully charged before it is reconnected to the system. The float voltage for the separated battery can be set to a value different from the system float voltage (=> boost voltage). After the battery is fully charged, the float voltage is set to the same value as the system float voltage (or lower). After the voltage of the separated battery has settled to the system voltage, the battery can be reconnected to the system. With the semi-automatic separate charge and discharge the system voltage is reduced to reconnect voltage «Urecon» during separate charging. After the voltage of the separated battery has reached the system voltage, the system voltage tracks the separate charging voltage for a short time and then the battery can be reconnected to the system. The battery is then charged up to the system float voltage. During separate charge mode, battery fuse alarms and Idiff measurement are suppressed.

Battery Test PSC 3 offers different procedures to check the state of the batteries. User can select between constant current and real load battery tests, depending on the system size and the load conditions. The constant current battery test discharges the battery with a constant current during a certain time. As an alternative in systems with very small or heavily varying load currents, the real load battery test can be selected. The main difference is that during the real load battery test the rectifiers do not deliver any current to load, as long as the battery voltage remains above the support voltage. During the Constant Current battery test, the battery is being discharged with a constant current. Load changes are being balanced by the rectifiers. For successful test the load current must be larger than the desired battery discharge current. During the Real Load battery test the battery is being discharged with the real load current. To make the testing safe the rectifier output voltage is programmed to Usupport voltage level but the rectifiers remain in operation. Parameter

Low Voltage Disconnection (LVD) The low voltage disconnection (LVD) function protects the battery from a deep discharge. During a mains failure, when the battery voltage drops below a threshold, the PSC 3 activates an event that drives the relay of the battery disconnect (if accordingly configured). The battery will be disconnected from the load until the system voltage Usys rises back to acceptable values.

6.4.1

Configuration The LVD is normally configured at the Delta factory. The following PSC 3 configuration instruction goes through the steps from the beginning, but it can also be used as a guide to understand and edit the parameters. To configure the PSC 3 and set the LVD in operation, all the hardware components (LVD, driver board, cabling etc.) must be installed in the power system. Step 1.

Login to the PSC 3 Configuration and Supervision Tool (web interface).

Step 2.

First an event and thresholds driving the LVD must be created. Go to the menu: Configuration > Signal Processing Engine > Event Definitions.

Step 3.

In the «Event Definition Overview» window, create a new event by choosing a measurement the new LVD event is based on (System voltage “Usys”) from the drop down menu «New Event(s) on Measurement». Then click on the «Add» button.

Step 4.

A new «Threshold Editor» window opens. Give a describing name for the LVD event, such as “LVD [U]” to «Too Low Event».

Step 5.

Set the parameters «Lower Threshold» and «Lower Threshold Hysteresis». The parameter «Lower Threshold» is the voltage threshold for the LVD and the «Lower Threshold Hysteresis» is the parameter for voltage returning to acceptable values. Then click on the «Add New Definition».

Step 6.

The next step is to define this event as a LVD event for the PSC 3, which will enable some special functions such as “LVD inhibit”. Go to the menu: Configuration > System Architecture > LVD.

Step 7.

In the «LVD Overview window» give a name for the LVD event, such as “LVD_1”, and click on the «Add». A new «LVD Setup» window opens.

Step 8.

Define the event that drives the LVD (defined earlier as “LVD [U]”) and give a delay for activation if needed. Then click on the «Add LVD». Now the event is shown in the «LVD Overview» window, with the “State” and an event “L LVD_1” will appear to event lists. The prefix “L” in the event name, describes it as LVD event. Now the event driving the LVD has been created, but there must still be assigned the correct output relay responsible for the activation and deactivation of the LVD. Check the cabling.

Step 9.

62

Go to the menu: Configuration > I/O > PSC3 (if a PSC 3 Output is to be assigned) or to menu Configuration > I/O > SSM > Setup (if a SSM Output is to be assigned), then select “L LVD_1” from the drop-down list to assign it the desired output number.

CONTROLLER PSC 3

Partial Load Disconnection (PLD) With the partial load disconnection function it is possible to prioritise separate load strings (e.g. for GSM and UMTS) during mains failure and battery discharge. In the simplest case the disconnection in based on low voltage threshold. The following configuration example is for a case where the disconnection is based on three conditions: mains failure, low voltage threshold and time threshold from mains failure. These three conditions are combined together to an event driving the PLD relay with «AND» and «OR» conditions. When the conditions are fulfilled the combined event and related relay are activated. If you are using only the voltage threshold, the steps 1-6 and 18-19 of the instruction apply. This configuration can only be done using the web interface. This flexible functionality is enabled by the PSC 3’s Signal Processing Engine, which uses measurements to create events, and further combine them to serve different functions (e.g. digital output relays).

6.5.1

Configuration Step 1.

Login to the PSC 3 Configuration and Supervision Tool (web interface).

Step 2.

First an event and thresholds driving the PLD, based on system voltage, must be created. Go to the menu: Configuration > Signal Processing Engine > Event Definitions.

Step 3.

In the «Event Definition Overview» window, create a new event by choosing the “Usys” measurement from the drop down menu «New Event(s) on Measurement» as the bases for the new PLD event. Then click on the «Add» button.

Step 4.

A new «Threshold Editor» window opens. Give a describing name for the PLD event, such as “PLD [U]” to «Too Low Event».

Step 5.

Set the parameters «Lower Threshold» and «Lower Threshold Hysteresis». The parameter «Lower Threshold» is the voltage threshold for the PLD and the «Lower Threshold Hysteresis» is the parameter for voltage returning to acceptable values. Then click on the «Add New Definition».

Step 6.

Create more voltage based events for the other PLDs with different voltage thresholds. Use the same naming system e.g. “PLD2 [U], PLD3 [U]…”

Step 7.

The next step is to create a threshold based on time. The PSC 3 counts time from the mains failure and if the defined time threshold is bypassed the event is activated. Go to the menu: Configuration > Signal Processing Engine > Event Processing

Step 8.

In the «Event Processing» window, choose the «Event Type» as “Filter” from the drop down menu at the bottom of the window. Then click on «Add» button.

Step 9.

In the new «Filtered Event» window, give a describing name e.g. “PLD[t]” for the new PLD event based on time filtering. Then choose the event “S Mainsfailure” from the drop down menu as a base for the time filtered event. Then define the TRUE and FALSE time thresholds. The TRUE value is the delay for the event to be activated after mains failure (e.g. 10 min for UMTS and 3h for GSM). The FALSE value is the

20.06.2008

65


CONTROLLER PSC 3

delay for the event to be deactivated after mains is back on. When done, click on the «Add New Definition» button. Step 10.

Create more time filtered events for the other PLDs with different voltage thresholds. Use the same naming system e.g. “PLD2[t], PLD3[t]…”

Step 11.

The next step is to combine the voltage based events with a mains failure condition. This combination will ensure that both the low voltage and mains failure conditions are fulfilled (using an AND-condition) before partial load disconnection.

Step 12.

This is done in the Event Processing menu as well. Choose the «Event Type» as “AND” from the drop down menu at the bottom of the window. Then click on «Add» button.

Step 13.

Name the new event as PLD1 [MF x U] (“x” is a symbol for AND). Choose the events “S Mainsfailure” and “PLD1 [U]” as inputs for the function. Then click on the «Accept New Definition» button. Add more similar events, if needed.

Step 14.

The next step is to further combine the previous event(s) with a time threshold from mains failure (with an OR-condition). This is done in the same menu: Configuration > Signal Processing Engine > Event Processing

Step 15.

Choose the «Event Type» as “OR” from the drop down menu at the bottom of the window. Then click on «Add» button.

Step 16.

In the new «OR Event» window, give a name e.g. “PLD1 [MF x U + t]” (“+” is a symbol for OR) for the new combined PLD event. Then choose the events “PLD1 [MF x U]” and “PLD1 [t]” as OR conditions for the event from the drop down menus. Create more combined events for the PLDs with the same method.

Step 17.

Now the events and thresholds are created for the PLD function. The next step is to define these combined events as LVD events for the PSC 3, which will enable some special functions such as “LVD inhibit”. Go to the menu: Configuration > System Architecture > LVD.

Step 18.

In the «LVD Overview window» give a name for the PLD event, such as “PLD_1”, and click on the «Add». A new «LVD Setup» window opens. Choose the event “PLD1 [MF x U + t]” from the drop down menu for the setting «Event» and click on «Add LVD». Now the event is shown in the «LVD Overview» window with the “State” and an event “L PLD_1” will appear to event lists. The prefix “L” in the event name, describes it as LVD event. Now the event driving the PLD has been created, but there must still be assigned the correct output relay responsible for the activation and deactivation of the PLD. Check the cabling.

Step 19.

66

Go to the menu: Configuration > I/O > PSC3 (if a PSC 3 Output is to be assigned) or to menu Configuration > I/O > SSM > Setup (if a SSM Output is to be assigned) and define the LVD event “L PLD_1” to the desired output. Assign the further PLDs accordingly. Then click on the «Accept Changes» button and save the settings permanently by clicking on the «Save» button on the main screen.

RECTIFIERS A rectifier converts AC power to DC power to supply the load and charge the batteries. The rectifier parameters (voltage, current etc.) are adjusted according to the battery and load. The PSC 3 offers a comprehensive set of functions to control and monitor different rectifiers, enabling the user to adjust the behaviour of the rectifiers to meet the specific requirements. The communication between the controller and rectifiers is established and maintained through a digital system bus (IMBUS). The exact functionality depends on the type of rectifier used. For details, which functions are supported and which parameter ranges apply, read the appropriate rectifier documentation. The following instructions go through the main functions from the PSC 3 point of view, with step-by-step instructions.

7.1

Rectifier Overview Analogue as well as digital rectifiers can be seen as a programmable voltage source with the following input and output characteristics.

Input Charateristics The rectifier starts working if the auxiliary supply starts operation, but if the input voltage is outside the specified window, the rectifier works only in standby without any power drain. This standby state is possible, if the input voltage is lower than ‘Input Low Off’ or if the voltage is higher than ‘Input High Off’. If the input voltage is lower than ‘Input Voltage Power Reduction’ or the temperature is higher than the nominal temperature, the output power will be reduced. If the temperature is higher than maximal temperature the rectifier switches off. Note!

'Off' means in the following points 'standby'. The rectifier is really off only if the auxiliary supply isn't operational. If the rectifier is really off, the communication with PSC 3 is not possible.

Output Characteristics The rectifier's output static characteristic has three regions of operation as shown in the figure below. Mode: Voltage The constant voltage mode is shown as a horizontal line in the figure below. This mode stabilises the output voltage at the set or remotely controlled value. In the system, the load sharing function additionally affects the voltage of the individual rectifier. Mode: Power Limit The constant power mode (power = output voltage * output current = const) is realised by the microcontroller by limiting the output power.

Rectifier Parameters After communication is first established between the rectifiers and the controller it is possible to adjust the parameters with the controller. Without initial communication to the power system controller Delta’s rectifiers use their own default parameters. With the controller the user can also adjust the default parameters, after the communication is first established. The following parameters control the behaviour of the rectifiers when the power system is not in normal operating mode, such as start-up or low input voltage mode. The parameters for normal operating mode (float charge mode), and for the whole power system, are adjusted elsewhere (e.g. battery menu). Selection: Parameter

Rectifier Alarming In case a rectifier is not working correctly or shuts down for some reason, the PSC 3 gives a rectifier failure alarm (RFA → internal events: S Non Urg RFA or S Urgent RFA). The rectifier is considered as faulty if at least one of the following criteria is fulfilled: •

Rectifier shut down by over temperature protection (OTP), over voltage protection (OVP) or air flow failure

•

Load sharing error (voltage mode only)

•

Input voltage outside range (open MCB or faulty AC cabling)

•

Internal failure

The urgency of an alarm (Non Urgent or Urgent) can be adjusted with thresholds provided by the PSC 3. Parameter

Explanation

Rectifier Efficiency Mode and Cycling The rectifiers are able to communicate with the PSC 3 using advanced communication protocols. This allows optimising the system performance by controlling the rectifiers individually. The PSC 3 software currently supports a Rectifier Efficiency Mode with Rectifier Cycling to adapt the power supply to a momentary load, which reduces power losses and increases the system efficiency. In addition, with the Forced Rectifier Cycling, it is possible to avoid always using the same rectifiers to feed power to the system.

7.5.1

Rectifier Efficiency Mode The Rectifier Efficiency Mode allows to run only as many rectifiers as needed for an optimum overall system performance for a momentary load. Several parameters are required to specify how many rectifiers are allowed to be turned off and still be able to react on instantly increasing power demand. The rectifiers that are turned off are cycled to make sure all of them are operating correctly even if PSC 3 has turned them off. The following figure shows an example how it works. P

Power Limitation by Event This feature gives a possibility to save costs by using under-dimensioned generator sets for power supply during mains outages. In this case the generator gives only a part of the power needed, while the battery delivers the rest. So the battery is being partially discharged but the backup time can be extended. This is achieved by decreasing the rectifier output power during genset operation.

CONTROLLER PSC 3

ALARMS Alarms are an important aspect of the reliability of a power system. Well designed alarm handling can notify the user of an unexpected behaviour of the power system, in case of a mains failure, low voltage, rectifier failure etc. The PSC 3 controller offers flexible alarm handling in a form of the Signal Processing Engine. Different measurement signals, such as voltage, of the power system can be connected to the PSC 3 for further processing. By setting different thresholds for the measurements in the Signal Processing Engine the user can create events. Events can be mapped directly to an output or used again as an input for further signal processing with Boolean logic (AND, OR, Inversion) and other building blocks (Filter). It is recommended that the events that are used for the relay outputs are defined as alarm events; though attaching a normal event directly to a relay is possible as well. Defining an event as Alarm (or LVD) event adds additional functionality and behaviour to them. The PSC 3 controller offers enhanced alarm maintenance functionality, providing help for installation and debugging purposes. Each alarm can be forced to a certain value or can be frozen for a while. For identifying the alarm source, PSC 3 offers also an alarm inspection function, which simplifies the identification of the real alarm source, e.g. if the alarm is the result of a more complicated logical combination. All events can also be added to the logged events (system log). The Figure 92 describes the logic behind the controller’s signal processing (read the chart from left to right).

CONTROLLER PSC 3

Measurements All signals that are to be processed by the PSC 3 controller must be defined as measurements. Some of them (so-called system measurements) are predefined and others are generated automatically by defining other system components. There are three different types of measurements available: Digital, Analogue and Temperature measurements. Digital Measurement A digital measurement has an adjustable switching level for both directions using the threshold and hysteresis setting. This can be used for conditioning even very noisy signal sources. Analogue Measurement The analogue measurement is used to monitor voltage signals. The measured voltage may be corrected in a certain range by calibration. Temperature Measurement A temperature measurement converts the signal directly to a temperature value. The measured temperature may be calibrated if necessary. Note!

Before creating a measurement to the PSC 3 check that the hardware supports the measurement.

Event Definitions In order to use the signal processing engine together with analogue (including temperature) measurements, they must be digitised first. Defining a threshold and a hysteresis value for the measurement does this. Each definition, made up of a threshold value and a hysteresis, must have a unique name. The result of this definition is an event. In the PSC 3 some internal system events are created by default at the Delta factory. The threshold editor within the Event Definition allows defining both polarities of events. As many different thresholds as needed per measurement can be defined.

Alarm Setup Defining an event as an alarm event adds additional functionality and behaviour to it: •

The alarm events are internally inverted for the relay outputs. An alarm event (alarm active) releases the relay and therefore the alarm active status is also present if the system is not powered. In other words, when alarm is not active the relay is Normally Open (NO) and when alarm is activated the relay switches to Normally Closed (NC).

•

Only alarm events can be inhibited, in the output relays, with the function Alarm Stop. This is useful during maintenance when alarms are normal, but do not require any actions. The critical alarms are usually driving some relays that activate external alarming systems. These alarms can be quickly inhibited with the Alarm Stop function (button «Stop Alarms» at the top of the browser window or menu «3.2 ALARM STOP» in the UIM interface).

•

Only the alarm events are displayed on the UIM interface when they are active (menu «3.1 ALARM LIST»).

Note!

The events defined as alarms receive automatically a prefix «A» in front of the event name.

Internal Events and Alarms The PSC 3 controller internally generates some measurements and events. They have a prefix "S" in front of the event name, and the name cannot be changed or deleted. In addition to the system events, the PSC 3 automatically generates some events when functions are taken in to use (e.g. LVD). These events receive a prefix as well, which describes to purpose or use of the event. The different prefixes are described in the table below. Prefix

Explanation

“A“

Alarm event. If an Alarm is configured based on an event named e.g. “Batt1”, then the system generates an event called “A Batt1” which then can be assigned to the real output. LVD open event for LVD supervision. If e.g. a Battery String named “Batt1” with an integrated LVD supervision is configured, then the system automatically generates an event called “D Batt1” which then can be used for further Signal Processing. Current measurement of a Battery or Load String. If a Battery is configured which is called e.g. “Batt1”, then the system automatically generates a measurement called “IBatt1” which then can be used for further Signal Processing. LVD event. If an LVD with e.g. name “DiscLoad1” is configured, then the system generates an event called “L DiscLoad1” which then can be assigned to the real output. System Events. These events are PSC 3 internal events.

“D“

“I“

These events do not necessarily activate any external alarms by default. If you wish that a specific internal event be included in the Urgent or Non Urgent Alarms, you need to add them to the alarm definitions. The definitions of Urgent Alarm and Non Urgent Alarm are located in the web interface menu: Configuration > Signal Processing Engine > Event Processing For more information read chapter 8.3 Event Processing. The table below describes the internal system events, which exist by default in the PSC 3 controller.

Alarm Tracing When an alarm has been detected and activated according to the configuration (relay output, LED, buzzer), the alarm source and original problem causing the alarm needs to be traced. The PSC 3 controller offers excellent alarm tracing possibilities, even remotely from an operating and maintenance centre (OMC). This feature is enabled with the PSC 3 web user interface (PSC 3 Configuration and Supervision Tool). The initial alarm is usually caused by a single event within a combination of events, and the alarm gives just an indication of a problem in the system. With the alarm inspection function the user has the possibility to easily navigate through the whole hierarchy of the logical combinations using the buttons «Inspect» and «Back» of the PSC 3 web user interface, and get to the root of problem.

USER AND SESSION MANAGEMENT

11.1

User Management To control access from different locations to the PSC 3 Configuration and Supervision Tool, PSC 3 has a build in User and Session Management System. It enables setting up a list of users with different access rights (e.g. configuration, maintenance, operator and monitor). Each login generates a session, which runs until the user logs out or until PSC 3 terminates it under certain circumstances. A special user, the administrator, may edit the user list and also define the rules, which apply if more than one session is running at the same time. The User and Session Managements are located in the web user interface (PSC 3 Configuration and Supervision Tool) menus: Home > System > User Management

and

Home > System > Session Management

CONTROLLER PSC 3

11.1.1 Default User Profiles and Access Levels The PSC 3 controller has some predefined user profiles for the Configuration and Supervision Tool. With the user profile «Admin» it is possible to edit the default profiles (e.g. reset the password) as well as add new ones. Most of the user profiles can also be deleted with administrator rights. The rest of the default user profiles are for configuring and operating the power system. In the table below are the default user names and passwords, with the corresponding access profile. It is recommended to change at least the passwords after commissioning the system. A password can be only be edited by the corresponding user. With «Admin» rights the passwords can be reset to default passwords. Username

Setup Upload and Download The Setup Handler administrates the numerous parameters of a PSC 3 system. This unit remembers the system configuration and keeps a track of the complex interaction between subsystem components. The whole configuration can be stored in a file or loaded from a file to the PSC 3. With PSC 3 it is possible to upload a configuration. This is a useful feature for customers having several similar sites. Only one configuration has to be prepared, which then can be downloaded to several sites by changing only site relevant parameters e.g. site name or TCP/IP settings. Requirements for a setup upload or download: •


•

The new Setup file is located in the TFTP server base directory (upload)

•


•


Be aware: •

The upload process may take several minutes. When started, don’t try to do anything else on the web GUI, except if the upload fails.

•

After starting an upload process, the PSC 3 needs to make a reset. It will be done automatically after a successful upload.

DPS 1200B_2000B-48-12_8 CS WITH PSC 3

Controller calibration Controller of the system is pre-calibrated (including rectifiers) by means of accurate meters at the factory of Delta Energy Systems. Calibration is not needed unless some changes have been made to the controller hardware or display of the controller is different than real accurate measurement at maintenance. Calibrate the system voltage of the controller according to the following instructions.

16

Step 1.

Measure the system voltage between the plus busbar [1, 3] and minus on the DC-output circuit breaker [2, 7].

Step 2.

Check the value «Usys» from the display.

Note!

The factory setting for output voltage is always 53.5 V for the FR 48 V – 2000 W – E and DPR 1200B-48 rectifiers.

Note!

If the value differs more than 0.1 Volts from the measured value, the controller calibration should be performed. Otherwise continue to the Step 11. The calibration is explained in the following Steps 4-10.

Step 3.

6.3

DPS 1200B_2000B-48-12_8 CS WITH PSC 3

Step 6.

In the new Analogue Measurement window click on the «Calibrate» button.

Step 7.

In the Calibration window enter the exact value measured with a voltmeter and click on «Calibrate».

Step 8.

The changes made to the PSC 3 parameters need to be saved to make them permanent. Go to menu: Configuration > Setup Update

Step 9.

In the Setup Update window click on the «Save» button in the User Setup section. Then log out from the PSC 3 Configuration and Supervision Tool.

Step 10.

Switch on the low voltage disconnection circuit breaker AF11 and then the battery circuit breaker(s) [4] into «ON» -position.

Step 11.

Check the battery polarity by measuring the voltage over the battery circuit breaker [4]. The voltage should be at most a few volts. If voltage is more than that, the battery polarity is not correct and it must be changed by switching the “+” and “-” cables connected to the batteries.

Step 12.

Check, that the load is connected to the distribution DC-terminals and switch on the DC-distribution circuit breakers connected to the load [2, 7].

Step 13.

Check the functioning of the system according to the next two chapters for rectifiers and the controller.

Checking the functioning of the rectifiers Following procedures are able to accomplish only with a suitable DC-load available. Check that the rectifiers are able to deliver current. The method is to first discharge the batteries for a while and then recharge them. The controller carries out the procedure, which decreases the rectifier voltages below the discharging voltage of the batteries. Therefore in case of a battery failure the system will not crash. Step 1.

Start the discharging by logging in to the PSC 3 Configuration and Supervision Tool. Activate the battery test manually from the controller menu Battery > Control > Battery Test by clicking on the «Start» button.

Step 2.

Let the controller discharge the batteries a few minutes.

After making changes to the PSC 3 settings, remember to save them in the menu Configuration > Setup Update. Otherwise the changes will be lost after rebooting the PSC 3.

Check the alarms as follows With the alarm test function of the controller the functioning of the alarm relays and LEDs can be checked in the PSC 3 Configuration and Supervision Tool menu Maintenance > Alarm. The Alarm Maintenance window allows manipulation of alarms for maintenance and testing purposes. An alarm set to Frozen, Set or Reset state does not react on the source event as defined in the event conditions, but stays in the current position in case of «Frozen», or changes to «Active» in case of «Set», or changes to «Ok» in case of «Reset».

6.4.3

Check the fuse monitoring as follows Switch ON all the battery circuit breakers [4] and the DC-distribution MCBs [2, 7], which have load connected to. Note!

18

The following procedure leaves the connected load without power as long as the MCBs are in the OFF-position. Make sure it is allowed to turn off the load for the duration of this test.

11 July 2008


DPS 1200B_2000B-48-12_8 CS WITH PSC 3

Step 3.

Switch the load and battery breakers OFF and ON one after another, checking that the alarms are indicated as configured.

Note!

Only the MCBs are switched on and having the load or batteries connected will produce an alarm when switched off. Load fuse alarm will appear immediately, but battery fuse alarm may take a few minutes until battery voltage decreases enough (>300 mV). The active alarm can be read from the display menu «3.1 Alarm».

Step 4.

Check the rectifier failure alarm by switching “OFF” the AC-supply and check the following:

Check the battery current from the display: Battery current (Ibatt) positive

ÎNot Urgent Alarm

Battery current (Ibatt) negative (battery is discharging) ÎUrgent Alarm Load current (Iload) equals battery current (Ibatt)

ÎMains Failure

The active alarm can be read from the display menu «3.1 Alarm». Note!

During the test there may occur Usys Low and Usys High alarms, which should be omitted at this stage. If there is no load connected to the system, no module alarm will occur. The additional module alarm (RF) does not light up any LEDs on the controller. The alarm can be seen on the menu display, and it is also seen in a remote location. It can be measured in the alarm cable (see alarm connections).

Step 5.

POWER SYSTEM MAINTENANCE

2.1

Introduction The power system is designed for unmanned operation and normally all the actions are carried out automatically by the controller unit. Therefore the actions undertaken are either preventive maintenance or repair.

2.2

Preventive maintenance The purpose of the preventive maintenance is to reveal the potential failures of the monitoring and alarm circuitry. The exception is the batteries, which should be checked and maintained regularly according to the instructions of manufacturer delivered with the batteries. To ensure high system reliability the most important measures are: •

Verification of the mechanical condition and connections of the batteries.

•

Verification of the functioning of the controller unit.

To ensure the high life expectancy of the batteries the most important measures are: •

The quality of the battery maintenance, cell voltage, ambient temperature.

•

Verification of the battery float charge voltage.

2.3

Rectifier maintenance

2.3.1

Checking the functioning of the rectifiers Checking the functioning of the rectifiers is part of preventive maintenance actions recommended to be carried out once a year as follows. Check that the rectifiers are able to deliver current. The method is to first discharge the batteries for a while and then recharge them. The controller carries out the procedure, which decreases the rectifier voltages below the discharging voltage of the batteries. Therefore in case of a battery failure the system will not crash.

2.3.1.1 Power systems with PSC 1000 controller Step 1.

Start the discharging by activating the battery test manually from the controller sub-menu “8. Battery Test” and then from its sub-menu “8. Battery Test”. Press to activate the test.

Step 2.

Let the controller discharge the batteries few minutes.

Step 3.

Stop the battery test from the controller and exit from the battery test sub-menu.

PSC 3 alarms and sources

2.2.1

System status indications The alarm LEDs/indications of the PSC 3 UIM and web user interface can be assigned to any event by the user. Check your system status assignments in the web user interface (Configuration and Supervision Tool) menu: Configuration → I/O → System status & UIM Normally the LEDs are assigned as follows:

2.2.2

•

LED 1 / symbol “

” is assigned for “S Urgent Alarm” event

•

LED 2 / symbol “

” is assigned for “S Non Urg Alarm” event

•

LED 3 / symbol “

” is assigned for “S Alarm suppr.” event

•

LED 4 / symbol “

” is assigned for “S Mainsfailure” event

•

LED 5 / symbol “

” is assigned for “Special mode” event

Alarms and alarm sources The alarms and alarm indications in the PSC 3 controller are user-definable. The Urgent Alarm (UA), Non Urgent Alarm (NUA) and Mainsfailure Alarm exist as default in the controller. The flexibility of the PSC 3 allows the user to define any event in the controller under the UA and NUA alarm definitions. Also the naming of events is user-definable. The following events are the most common conditions for the UA and NUA alarms. The event names are based on the general instructions for configuring the PSC 3 (see Installation and Commissioning section). All events with prefix “S” are default system events that have a fixed name. Note!

These events can only be seen in the user interface module (UIM) as a source for UA or NUA alarms if they have been defined as alarms in the Alarm Setup menu of the web user interface. Otherwise they will be indicated only as UA or NUA alarms, without the further information about the alarm source. The alarm source investigation can then be done only through the web user interface of the PSC 3.

2.3


Rectifier alarms The following instructions can be helpful in case of a rectifier alarm, to find out whether a rectifier is faulty or the failure is outside the rectifier module.

2.3.1

Fan cooled rectifiers Internal failures can only be repaired in Delta Energy Systems factory, therefore the faulty rectifier module in the system must be replaced with a new unit. With some rectifiers the fan can be replaced (see maintenance instructions). LED «ok» is off and an alarm is given: Mains voltage is missing:

Check mains fuse and connector

OVP is activated:

Reset OVP by pulling out the connector for approx. 2 seconds

OTP is activated:

Check air flow at front, clean air filter

Fan failure, air flow blocked:

Check air flow at front, clean air filter, check fan and replace if necessary

Load sharing not working:

Check connector

DC connection open:

Check connector

Rectifier is faulty:

Replace rectifier module

Systems with PSC 3 and digital communication: additional troubleshooting: COM-LED off or blinking

Communication failed. Check bus cable to PSC 3. Check correct IMBUS termination.

If nothing helps, disconnect the AC connector (FR 48V-1200W) or pull out (FR 48V-2000W-E and DPR 1200B-48) the rectifier module for 1 minute to reset the microcontroller. The settings can only be checked or adjusted via separate connector to an external programming box containing the appropriated software.
