CAN-Bus

Controller Area Network. Standard field bus, which is used in automotive as well as in industrial applications. The ComBox-S module handles the completely autonomous transmission and reception of CAN telegrams. That means, once the transmit buffer has written or the receive buffer is empty no CPU time is required. The CAN unit can receive and transmit standard frames with 11-bit identifier as well as extended frames with 29-bit identifier. The baud rate is standard. 2.1.1

Central Controllers Guide 3 Energon1 - MCC 3.1

Introduction

The built-in Multi Compressor Controller can control up to 4 compressors including itself. Other compressor controllers then Mk iV require a ComBox-S connected to the CAN-network. Each controller on the network must have a NodeID from 1 to 4. No other addresses are allowed, and each address can be used only once. Maximum 1 VSD compressor is allowed in the Energon1 configuration. Also the VSD can be Energon1 master.

∆P is at least 0.1 bar; for good regulation band must be wide enough (dependent of sensor range) The compressor outlet pressure (of the MCC-Master) is used as the net pressure. It is also possible to configure a specific net pressure reading (even a pressure transmitter can be used): for more details: see X104 64S 088 Instruction remote sensor for MCC. Start / Load action if there is a VSD integrated in the Energon1 system : start/load action only if speed of VSD >= 0.95 x MaximumSpeedVSD Load area : Pressure below ∆P/3 zone : if dp/dt =< 5 mbar/s => action Load area : Pressure in ∆P/3 zone : if dp/dt =< 1 mbar/s => action Anticipating load zone : if dp/dt < 0 mbar/s => action Pressure in middle area or higher : no actions Unload action if there is a VSD integrated in the Energon1 system : unload action only if speed of VSD =< 1.05 x MinimumSpeedVSD Pressure in middle area or lower : no actions Anticipating unload zone : pressure in ∆P/3 zone : if dp/dt > 50 mbar/s => action Anticipating unload zone : pressure in ∆P/6 zone : if dp/dt > 0 mbar/s => action Unload zone : if dp/dt >= -2 mbar/s => action Stop action if there is a VSD integrated in the Energon1 system : Page 12


Central Controllers Guide VSD will stop based on its own algorithms, but referring to adjusted (in)direct stop levels and setpoint / netpressure coming from Energon1 master no influence on stopping other compressors Pressure lower then middle area : no stop actions Pressure in middle area or higher : stop action if Dp/dt > -5 mbar/s Unload Timer elapsed Load Timer elapsed DSS counter (based on allowed starts/day) elapsed VSD compressor: only 1 can be integrated in Energon1 system, it will always be the top load, regulates to a set point coming from Energon1 master – middle of the Energon1 pressure band. Also the actual regulation pressure is coming from the Energon1 master, to avoid influences of pressure difference between pressure seen by Energon1master and VSD. Also the stop levels are adjusted if VSD is under Energon1 control : the indirect stop level will be Pmax the direct stop = new setpoint + local direct stop level; but if the direct stop level < indirect stop level then the direct stop level = indirect stop level.

Integrating Mark 1/2/3 controller A ComBox-S interface is required; this box converts the CAN-protocol to RS232 serial protocol. The NodeId of the ComBox-S must be set to 1, 2, 3 or 4 to support Energon1 control.

4 Energon1 – MCC for SF 4.1

Introduction This product is the same as the previous Energon 1, but specific for controlling SF/MultiSF. No other types are supported. Also SF/MultiSF based on a Mark 3 controller can be directly connected via 1 digital input and 1 digital output for each Mk3-SF. As the MCC can have only 4 compressors, maximum 3 compressors can be connected to the DIOE module.

Recommended pressure band setting for Mk3-SF: If the net pressure seen by MCC Master and the outlet of the Mk3 slave are equal: Plow = P_MCC_high – 0.1 bar Phigh = P_MCC_high + 0.2 bar More details and recommended settings: see instructions 9820 4547 05

4.3.2

Priority

It is foreseen to have 2 priority schemes. Priority scheme 1 and scheme 2. In every priority scheme, it is possible to assign certain priority level to every compressor. As 4 compressors can be connected in a MCC, there are 4 priority levels possible (1,2,3 and 4) The compressor with lowest priority number will have highest priority for starting and the compressor with highest priority number will have lowest priority for starting. If the same priority level is assigned to 2 or more compressors, then Running Hours of those compressors are taken into consideration for deciding the highest priority among those compressors for starting. The priority schemes can be changed manually (using parameter settings) as well as automatically (by week timer).

Digital link connections

With the digital linking only Load/NoLoad compressors can be connected. For each compressor two digital inputs and two digital outputs are foreseen. One DIOE expansion box supports two digital linking channels. By downloading the DIOE type must be ‘Digital Link’. Digital inputs (use voltage free contacts from the compressor): o motor stopped (open) or running (closed) – DI01 or DI03 o unload (open) or load (closed) – DI02 or DI04 Digital outputs (both normal open and normal closed contacts are available): o local (de-energized) or remote (energized) – K01 or K03 o load (de-energized) or unload (energized) – K02 or K04 Maximum 6 Digital links are possible: Digital link 1 uses DI01, DI02 and K01, K02 of first DIOE module of type ‘digital link’, connected via I²C to Energon2 master module (with touch screen) Digital link 2 uses DI03, DI04 and K03, K04 of first DIOE module of type ‘digital link’ Digital link 3 uses DI01, DI02 and K01, K02 of second DIOE module of type ‘digital link’, connected via I²C Digital link 4 uses DI03, DI04 and K03, K04 of second DIOE module of type ‘digital link’ Digital link 5 uses DI01, DI02 and K01, K02 of third DIOE module of type ‘digital link’, connected via I²C Digital link 6 uses DI03, DI04 and K03, K04 of third DIOE module of type ‘digital link’ 5.2.4

Analogue readings

The net pressure is measured by a pressure transmitter -two wires connection. The supply of the Energon2 is used to generate the current. Only two wires and a shielding have to be wired from the Energon2 box towards the transmitter. For more details see service diagram 9820 3754 03. A second pressure transmitter can be connected as a back-up net pressure measurement. 5.2.5

Optional ‘remote control’ DIOE

This DIOE is always the first connected DIOE via I²C to the Energon2 master module. It provides 4 digital inputs for remote control, this functionality is only available if the DIOE type ‘remote control’ is available and the Energon2 control mode is ‘digital remote’ Digital inputs (wiring between pin 8 and pins 3/4/5/6 of 6X9): o DI01: local control (open) or central control Page 19

DI02 and DI03 Both open = central stopped DI02 closed and DI03 open = SPS1 DI02 open and DI03 closed = SPS2 DI02 closed and DI03 closed = SPS3 DI04: not used

There are 4 digital outputs for indication-purposes; this functionality is only available if the DIOE type ‘remote control’ is available. For each digital output both normal open and normal closed contacts are available o K01 = Normal (energized) or System Alarm (de-energized) o K02 = Normal (energized) or Net pressure Alarm (de-energized) o K03 = Normal (energized) or Net pressure Warning (de-energized) o K04 = Local Control (de-energized) or Central Control (energized)

5.3

Setup Hardware (see instruction manual 2920 1597 00 and service diagram 9820 3754 03): During the commissioning the pressure transmitters are wired towards the Energon2 cabinet The DIOE expansion boxes are mounted onto a DIN-rail in the cabinet; power supply and digital I/O has to be wired to the DIOE. A CAN cable is wired from the Energon2 main controller to all compressors linked via CL. For DL wiring is made from the EPn compressors directly to the DIOE modules in the Energon2 cabinet. Software: Using the Energon2_CP commissioning software the Energon2 can be downloaded. • via cross Ethernet cable directly between PC and Energon2 • onto the flash card using a card reader/writer, after download, insert the flash card into Energon2 With the commissioning program all settings and parameters can be seen and manipulated. It is also possible to transfer and convert logging files from the Energon2 for further analysis.

∆P is at least 0.1 bar; for good regulation band must be wide enough (dependent of sensor range); When Load/NoLoad compressors are part of the network typical a pressure band of minimum 0.4 bar is required. When more VSD compressors are present, one will regulate as the top load regulating to the middle of the pressure band using its local PI settings. The other VSD’s are steered in speed steps based on the slope of pressure change. Load/NoLoad compressors are (un)loaded when slopes are higher and/or when pressure is outside middle area.

Page 20


Central Controllers Guide When the net pressure goes outside the alarm levels and if alarm protection is active, the Energon2 will revert all compressors to local control. The regulation algorithm takes into account the following data to decide taking a specific action • Actual net pressure • Slope of de-creasing or in-creasing of the net pressure • Availability and type of connected compressors • Definition of the sequence groups • Running hours of each compressor (for equal wear) – within sequence groups • Minimum, maximum speed and the optimal used area for VSD The result of the pressure regulation algorithm is one of the following actions: FOR VSD • Install C-VSD (VSD will regulate based on its own PI-control algorithm) • Uninstall C- VSD (PI-control of VSD disabled; speed fixed) • Stop (only applicable for VSD without throttle) • Unload (only applicable for VSD with throttle) • Less speed • More speed FOR LOAD/UNLOAD • Start & Load • Load • Unload Based on the amount of added or removed capacity, a compensation-action can be performed. Loading a big compressor will be compensated by steering less speed command to a VSD and unloading a big compressor will be compensated by steering more speed to a VSD. 5.4.2

Control modes

The Energon2 has the following control modes: • Local control: all connected compressors are running/stopped locally, Energon2 only collects all data and is waiting for start/stop command from the operator. • Central – regulating: the Energon2 controls all integrated compressors (isolated compressor can be running or stopped locally) to keep the net pressure within the regulation band • Central – stopped: the Energon2 stops all integrated compressors, the net pressure will drop to 0 bar; this mode can be disabled. 5.4.3

Different System Pressure Bands (SPS)

There are 3 possible system pressure bands. Both manually and based on the week timer the Energon2 can regulate the net pressure within a different pressure band. Each pressure band has its own protection levels. When reaching the warning level an output can generate a warning signal. When the alarm level is reached the Energon2 will revert all compressors to local control and an alarm signal will be generated. The ‘automatic switching to local’ - function can be disabled. 5.4.4

Different Sequence Schemes

There are 8 possible sequence schemes. Both manually and based on the week timer the Energon2 will select the compressors based on a certain sequence. Compressors part of the same sequence group will be selected automatically to guarantee equal wear within this sequence group. Equal wear is guaranteed by selecting the compressor with the least running hours at an upload action and by selecting the compressor with the most running hours at a download action. The Energon2 has its own running hours-counter for each compressor. Whenever a VSD is keeping the pressure stable without the need of adding/removing capacity from load/NoLoad machines, the ‘forced sequencing’ algorithm will force adding the Load/NoLoad compressor with the least running hours, automatically will the pressure regulation algorithm unload/stop another Load/NoLoad machine (with the most running hours) Remark: equal wear is only guaranteed for Load/NoLoad compressors part of the same sequence group.

Page 21


Central Controllers Guide 5.4.5

Automatic Restart After Voltage Failure

After a power failure the Energon2 will automatically take over control again of all compressors and regulate the net pressure within the pressure band. The following settings are available Status: the function can be active or not Power recovery period: the function is only active if the power returns within this period (infinite exists also) Restart delay: after returning the power the first compressor will only be started after elapsing this period. 5.4.6

Week timer

The Energon2 has a real time clock and based on a week timer table up to 8 actions for each day can be programmed. The following commands are available: • System stop (will only be executed if this functionality is enabled • Activation of System Pressure Set 1, 2 or 3 (if necessary system start included) • Activation of Sequence Scheme 1, 2, 3, 4, 5, 6, 7 or 8. 5.4.7

Visualization

The Energon2 has a touch-panel display. The graphical display uses as much as possible icons and pictograms to give information. The instruction book gives more explanation regarding the user interface. Users and accessibility: each operator can be defined with a certain access level; based on this he is allowed to perform some actions or not. Graphical view: the net pressure can be seen in a trend view. 5.4.8

Energon2 parameters

The following parameters and settings are available to define each compressor channel: Global settings • date and time • unit selection for pressure, temperature and flow • language selection Regulation / system parameters • System stop: enable/disable • Control mode: local / remote / LAN (System start/stop and SPScontrol) • Motor Stop delay: time between two consecutive compressor stop commands • Motor Start delay: minimum time between two consecutive compressor start commands • Equal wear time (when difference between running hours becomes larger => select other compressor) • Integrate delay: time between two consecutive integrate actions • Isolate delay: time between two consecutive isolate actions • Used regulation parameter set: selection from 1 to 5; use a set with smaller number for installations with faster behaviour (small vessel) 5.4.9

Channel parameters

The following parameters and settings are available to define each compressor channel: Type Linked via Can communication (CL) Linked via DIOE and digital I/O (DL) Address For CL: the LANId of the compressor controller For DL: 1 – 6 defining which DIOE digital in/outputs are used Capacity Regulation takes into account difference between capacities; it does not perform capacity matching between air consumption and delivered flow Start response delay When a start command is sent, within this period the compressor must be running (to take care of permissive start conditions) Min/Max levels for optimal speed zone Specific for VSD, not applicable for Load/Unload (0 – 100 %) Page 22


Central Controllers Guide Pressure regulation algorithm will try to use the VSD within these limits. Idling time Additional condition for stopping a compressor: compressor will not be stopped if not running unload for this period (not applicable for DL => value = 0) Starting up time Specific for DL; when a start command is sent, within this period the compressor must be run loaded (to take care of Y-time and Load delay) Minimum Stop time Specific for DL (if linked via CL, the setting is automatically collected by the Energon2; after stopping of a compressor during this period the compressor is “not available” Running Hours For each compressor the Energon2 counts the running hours to guarantee equal wear. 5.4.10

Logging parameters

Energon2 has a built-in logging functionality. The PLC program writes the logging data onto the flash memory card. It’s important to make a back-up of the Flash Card before activating the logging, while the flash card can be become corrupted if power fails when writing onto the flash card. The following settings determine the logging: • Type o Event logging: every time the Energon2 takes an action a record is saved o Interval logging: records are saved base on a fixed period o Both logging can be done simultaneous • Interval : used by interval logging • Maximum Amount of Files o Maximum number of files that will be written on the flash card • Overwriting Files allowed: o If this is set: after writing the last logging file (Maximum Amount of Files) the first file will be overwritten o If this is not set: after writing the last logging file (Maximum Amount of Files) the logging stops 5.4.11

Loading/saving the Energon2 configuration

After the first download to the Energon2, it uses the default factory configuration and settings as defined by the operator using the Energon2_CP program. The Energon2 makes a copy of this in retain memory and will always use these configuration and settings. The settings (part of the retain memory) can be changed by the operator via the touch screen. The operator can make a copy of the configuration and settings onto the flash card. 5 slots are available. Also the factory file can be overwritten (only by user with access level 0, this is intended only for the Atlas Copco service engineer). The stored configuration and settings can be loaded into retain memory (only if Energon2 is in local control mode).

Central Controllers Guide 6 ES100 6.1

Introduction

The ES100 is a Sequence Selector based on Elektronikon Mark 3. It can control up to 7 compressors. The Pressure Band Controller steers the compressors trying to keep the pressure within the regulation band and it controls the sequence of the connected compressors. It can control only load / no load compressors. The ES100 exists in different versions, dependent of the requested digital and/or communication links. HRR Standard + COM3 (standard ES100) : provides 3 digital and 4 comm. links HRR Standard + DIOE : provides 7 digital links HRR Standard + DIOE + COM3 : provides 7 digital and 4 comm. links HRR Standard + COM3 + COM3 : provides 3 digital and 8 comm. links The linking with the compressors can be made either by serial communication (both sending commands and receiving status data) through a current loop connection between ES100 and the compressor or by connecting digital inputs and outputs between the ES100 and the compressor. The ES100 will be mounted in a cubicle; connections for in- and outputs towards the compressors have to be made when the ES100 system is installed (see instruction manual). MK3 ES100

Digital input/output link.

The digital compressor link contains inputs and outputs. For each compressor the ES100 has two outputs (normal open and normal close contacts available) : local / remote control : for switching the compressor to remote pressure sensing mode load / unload control : for steering the compressor to (un)load The ES100 has also 2 digital inputs for each compressor for feedback purposes: stopped / running : indicating the motor status of the compressor unloaded / loaded : indicating unload / load status of the compressor Mk iV controller equipped compressors can be connected to the ES100 via digital linking, although the communication link is more easily for wiring. Only compressor of the Load/No Load type are supported. The position of the digital inputs for remote load/unload control is D4 and the load/unload digital input is D3, see service diagrams. The position of the digital outputs for stopped/running is K01 and for Unload/Load K04, a voltage free contact must be used, see service diagram for details.

Mk iV

To connect a Mk iV controller equipped compressors to the ES100 via communication linking, the current loop line must be converted to CAN; this can be done using the ComBox-S. For every compressor with a Mk iV controller you need a ComBox-S. You have to set the CAN NodeId of the MkiV controller to 1,2,3 or 4. The CAN NodeId of the ComBox-S can be set from 1 to 30, but has to be different from the address of the compressor controller and NodeId 31 may not be used.

For every compressor with a Mk iV controller you need a ComBox-S. You have to set the CAN NodeId of the MkiV controller to 1,2,3 or 4., The CAN NodeID of the ComBox-S can be set from 1 to 30, but has to be different from the address of the compressor controller Required Cabling :

Central Controllers Guide 8 ES20 / ES30 8.1

Introduction

The ES20/30 is the first generation intelligent net pressure controller. It can control up to 6 / 12 Load/NoLoad compressors. The pressure band controller steers the compressors to keep the net pressure within the regulation band.

8.2 8.2.1

Communication link Load/NoLoad Compressor without Electronic Controller

The ES01 interface is required, this is an obsolete interface box. Also the newer generation ES001 (based on Mark3 hardware) and ES003 (based on MkIV hardware) can be used as interface box. Important Note : Using these interface in some extreme situation problems might occur. To be used only is exceptional cases, field tests are required ! The communication link is established as with a compressor equipped with a Mark 3 controller for more details : see Electronic Systems Guide : 9824 0719 00. 8.2.2

Load/NoLoad Compressor with Mark 1 / 2 controller

The controller directly supports current loop, which can be connected to the ES100 cubicle, for more details : see Electronic Systems Guide : 9824 0719 00 8.2.3
