7 TRIP and Fault Reset
7.1 TRIP
TRIP may be considered as event or status of the unit (see chapters bellow).
7.1.1 TRIP event
Starts in the moment of terminating the count-down of any protective function with delay, or in the moment of
activation of any immediate protective function.
As a result of the trip event, are e.g. the following consequences:
Immediate deactivation of outputs !CommTrpPer and !CommTrpImp or activation of CommTrpPer and
CommTrpImp
LED TRIP goes to red
The appropriate counter in the statistics screen increments
The cause of the TRIP event is recorded among the last five history events
The Last Trip Time timer starts to count time and the last trip indication is set
7.1.2 TRIP status
Starts at the moment of TRIP event
During this status, the appropriate outputs are kept in fault position
During this status, it is not possible to perform Fault reset
TRIP status is active until a successful Fault reset. This may not be done before all measured and evaluated
values are within preset limits.
If during the TRIP status, caused by some value, another value overreached its limits for TRIP evaluation,
this second overreach is not considered as TRIP. It does not cause a second TRIP event. However, as a
consequence of this, the TRIP duration may be prolonged until the moment when both (all) values are within
limits.
If the BI Disable is set to ENABLED and the BI Disable is activated during this state, the TRIP status is
terminated and the fault is reset.
If the BI Disable is set to ENABLEDexl.TRP and the BI Disable is activated during this state, it will have no
effect on the unit.
