Chapter 4 Setup Menus 45
4.13 Relay Operation Control
Menu
Î Î Î Î
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.
To select a relay:
9 Press to activate the middle
window, and then use the up/down arrow
keys to scroll to the desired relay.
To change the relay operation mode:
9 Press to activate the lower
window.
9 Use the up/down arrow keys to set the
desired option. Select nor for normal
(non-failsafe) relay operation, or select
FSAFE for failsafe relay operation.
9 Press to store your new setting
or press to leave your previous
setting unchanged.
To quit the setup menu:
9 From the middle window, press or
.
NOTES
1. You will not be able to change the relay operation mode if a relay has been
allocated for pulsing.
2. When a failsafe relay is allocated for pulsing, it automatically reverts to normal
operation.
