Setting Explanation
Trp 1+2 Both Trp 1 and Trp 2 outputs are activated in case of binary alarm
CB1 Feedback
This input indicates, whether the circuit breaker CB1 is open or closed. It is expected that this breaker
opens in case of CommTrp and Trp 1 activation. If it is configured in the unit and it does not open,
CB1 fail is indicated.
In general, this breaker corresponds to the "Mains Circuit Breaker" = MCB in the ComAp controllers
applications. Together with CB2 it indicates, whether the installation is in "parallel to mains" state (both
CB1 Feedback and CB2 Feedback are closed) or in island mode (one or both of CB1 Feedback or
CB2 Feedback are open).
CB2 Feedback
This input indicates, whether the circuit breaker CB2 is open or closed. It is expected that this breaker
opens in case of Trp 2 activation. If it is configured in the unit and it does not open, CB2 fail is
indicated.
This breaker can, but does not necessarily have to correspond to the "Generator Circuit breaker" =
GCB as used in the ComAp controllers applications. In such case, together with CB1 it indicates,
whether the installation is in "parallel to mains" state (both CB1 Feedback and CB2 Feedback are
closed) or in island mode (one or both of CB1 Feedback or CB2 Feedback are open).
F.R. Button
Activation of this binary input causes fault reset. The input has the same effect as pushing the Fault
Reset button
. If permanently activated, every 100ms an impulse to fault reset the unit is done
internally.
DC TripCircuit
Evaluation of DC trip circuit state. When the input closes, history record is made and a message "Wrn
DCTripCirc" appears in Alarmlist.
Access Lock
If the input is closed, no setpoints can be adjusted from controller front panel.
Hint:
Access lock does not protect setpoints from LiteEdit. To avoid unqualified changes the selected
setpoints can be password protected.
External Trip
The input serves for reading the state of external mains failure relay for the purpose of controlling the
NVD protection stage. Its activation means that the external relay has detected a mains failure. If the
input is active, NVD trip outputs are blocked. To unblock the NVD protection, it is necessary not only
to deactivate the External Trip input, but also deactivation of the feedback of the circuit breaker, which
is operated by the NVD protection stage. If the input changes its state, history record is made. There is
no Alarmlist record or trip protection connected with this input. See description of this lockout in
ANSI59N - NVD function description.
Block 1, Block 2
These inputs are used to disable a certain protection stage. To allow disabling/enabling the protection
stage by these inputs, assign them to this protection stage by setpoint Block BI. Enabling the
connected protection is delayed by time given by setpoint ProtActiv del. Please note that the Block
inputs trigger immediate fault reset in the moment of thier activation and deactivation.
