24 Installing the XM-320 Position Module
Figures 2.9 and 2.10 illustrate the behavior of the NC and NO terminals when
the relay is wired for failsafe, alarm or nonalarm condition or non-failsafe,
alarm or nonalarm condition.
IMPORTANT
T
The NC/NO terminal descriptions (page 22) correspond
to a de-energized (unpowered) relay.
When the relay is configured for non-failsafe operation, the
relay is normally de-energized.
When the relay is configured for failsafe operation, the
relay is normally energized, and the behavior of the NC and
NO terminals is inverted.
