Trips

The trips generated by REB500 can be viewed in the trip list together with the protection
functions that caused them (Menu Trips/ first column of list). In addition the corresponding
date/time information, source and values (if existing) can be displayed.
The following trips can appear on the local HMI:
TRIP(ITT):
BBP Trip:
BFP TRIP T1:
BFP TRIP T2:
OCDT TRIP:
PDF TRIP:
EFP TRIP:
EXTERNAL TRIP
DIST TRIP:
Further trip signal of Bay Protection (if existing)
All these information can be seen in the trip list by navigation via the right and left arrow keys
on the LHMI.
Table 22:

Trip
1) Navigation via the right and left arrow keys on the LHMI (Value can have entries in several columns)
2) Trip signals column is fixed on left side of the trip list
3) Value: information (number of columns) depends on the information content of the trip signal
4) Current value indications are generally instantaneous values

Avoid performing switching operations in the event of the following alarms
before the failure has been analyzed by correspondingly trained personnel:
• Isolator alarm
• Switch inhibit
• Differential current alarm
• Inspection and maintenance
Non-observance of this precaution can cause maloperation in normal operation
or a failure to trip in response to a fault.
Isolator alarm may only be acknowledged by appropriately trained and
authorized personnel. Non-observance of this precaution can cause mal-
operation in normal operation or a failure to trip in response to a fault.
