4th current transformer input th

The 4 current transformer input (terminals 59-60) is used for earth current (ground fault) measured in the transformer star point ground connection. rd The function includes a 3 harmonics filtering of the signal. This is selected by activating the alarm in setting 1730.

The setting of the CT is made in setting 6045 (primary) and 6046 (secondary).

Neutral line and ground fault inverse overcurrent These are configurable inverse alarms, based on predefined or user-configurable curve shapes. Settings are found in parameter 1730 (G Ie>> Inverse). Formula and settings used The inverse time overcurrent is based on IEC 60255 part 151. The function used is dependent time characteristic, and the formula used is:

k t(G) = TMS G

α

+c

-1 GS where t(G) k, c, α G GS TMS

is the theoretical operating time constant value of G in seconds are the constants characterising the selected curve is the measured value of the characteristic quantity is the setting value is the time multiplier setting

The constants k and c have a unit of seconds, α has no dimension. There is no intentional delay on reset. The function will reset when G < 2 x G S.

Fan Control Four configurable fans can be setup in the APU. The setup of the fans is done in menus 6562 to 6620. It is possible to use the display to setup the fans but it is recommended to setup the fans via the USW, because then it is possible to see all settings. Fan Input Fan temperature input is setup in parameter 6561. This input can be selected between multiinput 46, 47 or 48. Fan priority update At parameter 6562, the priority update rate is selected. If fan priority update is set to 0 hours, the sequence will be fixed to.: Fan A, Fan B, Fan C and Fan D. Fan control Stop/start of the fans is setup in parameter 6563 to 6574.

The following start/stop curve will be generated if a bow setting is used.

It is recommended to use the USW to setup the fans, because then it is possible at the same time to overview all four settings.

8. Power Management

In the following chapter, the power management functions of the APU 200 are listed. Power management functions: Load management Command timers CAN flags • • •

Load management The function is used to activate a relay when a specific amount of power is available. Each APU 200 has five levels which are adjusted in menus 8220-8260: • • • • •

Available power 1 Available power 2 Available power 3 Available power 4 Available power 5

These setpoints can activate a relay when the specific amount of available power is reached. The relay output can be used to connect load groups when sufficient power is available. The relays will activate when the available power is higher than the setpoint, but be aware that when the load groups are being connected, the available power will decrease and the relay(s) deactivate again if the available power is below the setpoint. So it is necessary to make an external holding circuit. The function is not depending on the running modes. The relays will activate in all modes including block. To avoid activation, e.g. when the APU is blocked, the inhibit function should be used.

Command timers (time-dependent start/stop) The purpose of the time-dependent start/stop function is to be able to start and stop functions automatically at specific times each weekday or certain weekdays. Up to eight command timers can be used for either start or stop functions. The settings are set up through the PC utility software. Each command can be set for the following time periods: • • • • •

Individual days (MO, TU, WE, TH, FR, SA, SU) MO, TU, WE, TH MO, TU, WE, TH, FR MO, TU, WE, TH, FR, SA, SU SA, SU

The command timers are to be used in M-Logic as events to set the command (start/stop). The time-dependent start and stop commands are pulses that are not sent until the moment the adjusted time is reached. It is necessary to use the PC utility software when setting up the time-dependent start/stop function.

Additional functions

This chapter includes functional descriptions of functions. Tables, diagrams and single-line illustrations will be used in order to simplify the information.

Alarm inhibit In order to select when the alarms are to be active, a configurable inhibit setting for every alarm has been made. The inhibit functionality is only available via the PC utility software. For every alarm, there is a drop-down window where it is possible to select which signals that have to be present in order to inhibit the alarm.

Selections for alarm inhibit: Function

Description

Inhibit 1 Inhibit 2 Inhibit 3 BTB ON BTB OFF BA voltage > 30%

M-Logic outputs: Conditions are programmed in M-Logic The bus breaker is closed The bus breaker is open Bus A voltage is above 30% of nominal Bus A voltage is below 30% of nominal

BA voltage < 30%

Inhibit of the alarm is active as long as one of the selected inhibit functions is active.

In this example, inhibit is set to BTB ON . Here, the alarm will be active when the BTB is not closed. When the BTB has been synchronised, the alarm will be disabled again.

The table illustrates the action of the fail classes. If, for instance, an alarm has been configured with the “Trip BTB” fail class, the following actions occur: The alarm horn relay will activate. The alarm will be displayed in the alarm info screen. The BTB will open instantly. • • •

In addition to the actions defined by the fail classes, it is possible to activate one or two relay outputs if additional relays are available in the unit. Fail class configuration The fail class can be selected for each alarm function either via the display or via the USW. To change the fail class via the USW, the alarm function to be configured must be selected. Select the desired fail class in the fail class scroll-down menu.

M-Logic M-Logic functionality is included in the unit and is not an option-dependent function. However, selecting additional options can increase the functionality. M-Logic is used to execute different commands at predefined conditions. M-Logic is not a PLC but substitutes one if only very simple commands are needed. M-Logic is a simple tool based on logic events. One or more input conditions are defined, and at the activation of those inputs, the defined output will occur. A great variety of inputs can be selected, such as digital inputs, alarm conditions and running conditions. A variety of the outputs can also be selected, such as relay outputs, change of modes and change of running modes. The M-Logic is part of the PC utility software 3, and as such it can only be configured in the PC utility software and not via the display. The main purpose of M-Logic is to give the operator/designer more flexible possibilities of operating the system.

Please refer to the “Help” function (F1) in the PC utility software for a full description of this configuration tool. Please refer to DEIF standard application note: “M-Logic” for further functional details.

Configurable alarm LEDs The four LEDs on the left side of the display can be controlled via M-Logic. For each LED, there is a choice between three colours (red, green and yellow) with or without blinking.

Example of Alarms LED configuration It is possible to programme the Alarm LEDs, to indicate highest phase current at any alarm. Start by programming the event A to un-acknowledge alarm, then programme event B to look at highest phase (L1, L2 or L3) current at any alarm.

Next step: Alarm LED to be active (LED 1, 2, 3 or 4), also which colour and effect this LED must have.

The following programming will activate (steady red) Alarm LED 1, whenever an un-acknowledge alarm is present, and the current was highest in L1 when the alarm was activated.
