Alarm
If the input is closed (or opened), the configured binary alarm is activated.
Alarm types:
Setting
Explanation
Warning
No trip, in case of activation, warning appears in the alarm list
Comm Trp
Only Comm Trp output is activated in case of binary alarm
Trp 1
Trp 1 output is activated in case of binary alarm
Trp 2
Trp 2 output is activated in case of binary alarm
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
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
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
. The input has the same effect as pushing the Fault
Reset button
. If permanently activated, every 100ms an impulse to reset the fault is sent
internally within the unit.
DC TripCircuit
Evaluation of DC trip circuit state. When the input closes, history record is made and a message "Wrn
DCTripCirc" appears in the 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
. To avoid unqualified changes the selected
setpoints can be password protected.
Ext MF Relay
The input serves for reading the state of external mains failure relay for the purpose of controlling the
. 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 Ext MF Relay input, but also to deactivate 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
