OUTPUTS
4–134
OPERATION
Range: Non-Failsafe, Failsafe
Default: Non-Failsafe
Failsafe operation causes the output relay to be energized when the Trip condition signal
is low and de-energized when the same signal is high. A failsafe relay also changes state
(if not already activated by an operand driving this output relay) when control power is
removed from the 845. Conversely a non-failsafe relay is de-energized in its normal non-
activated state and will not change state when control power is removed from the 845 (if
not already activated by a protection element).
EVENTS
