5 SETTINGS
Figure 5–32: TRIP BUS FIELDS IN THE PROTECTION SUMMARY
The following settings are available.
•
TRIP BUS 1 BLOCK: The trip bus output is blocked when the operand assigned to this setting is asserted.
•
TRIP BUS 1 PICKUP DELAY: This setting specifies a time delay to produce an output depending on how output is
used.
•
TRIP BUS 1 RESET DELAY: This setting specifies a time delay to reset an output command. The time delay should be
set long enough to allow the breaker or contactor to perform a required action.
•
TRIP BUS 1 INPUT 1 to TRIP BUS 1 INPUT 16: These settings select a FlexLogic™ operand to be assigned as an
input to the trip bus.
•
TRIP BUS 1 LATCHING: This setting enables or disables latching of the trip bus output. This is typically used when
lockout is required or user acknowledgement of the relay response is required.
•
TRIP BUS 1 RESET: The trip bus output is reset when the operand assigned to this setting is asserted. Note that the
operand is pre-wired to the reset gate of the latch, As such, a reset command the front panel interface or via
RESET OP
communications will reset the trip bus output.
