Figure 5–69: 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
RESET OP
operand is pre-wired to the reset gate of the latch, As such, a reset command the front panel interface or via
communications will reset the trip bus output.
