Relay Operation Control Menu - Satec C191HM Installation And Operation Manual

4.7 Relay Operation Control Menu

SELECT CHG
This menu allows you to set the relay operation mode: non-failsafe or failsafe.
Failsafe relay operation is the opposite of normal operation where relay contacts
are closed when a relay is operated (activated), and are open when a relay is
released (de-activated). In failsafe mode, an alarm is activated by a non-
energized relay which will open in all cases when an alarm condition is present
or an alarm setpoint is not operational either due to a loss of control power or
due to corruption of the setpoint setup configuration. A failsafe relay is closed
only if it is under setpoint control and no alarm conditions exist, or if it is manually
operated via communications.
