Relay Control
Relay Contact Ratings
The output relay contacts are intended to carry low voltage signals only. Do not exceed the
following ratings on the output relay contacts:
DC: 60 V, 30 W
AC: 30 Vrms, 1 A
Relay Settings
The Watchdog 100 Series units provide one output relay that can be operated remotely or set to
automatically open or close based on alarm conditions. A relay in non-latching mode will
automatically energize and de-energize as its associated alarms trip and clear. A relay in latching
mode will similarly energize on an alarm trip, but will only de-energize when acknowledged by
the user. See Alarms (page 18) for additional information on associating an alarm condition with
one of the output relays.
Manual Override
The output relay can be operated remotely through the Manual Override section of the Control
page. The user can force the relay to energize or de-energize by selecting the desired action in
a drop down menu and clicking the execute button. The current relay status is displayed in the
Manual Override section of the Control page. The word “forced” is displayed next to any relay
that has been manually forced to a given state. Any forced relay will not change state based on
alarm status. Relays can be released from a forced energized or forced de-energized state by
selecting the Release Override option in the drop down menu.
Acknowledgments
Any relay in latching mode will change from de-energized to energized if it receives an alarm trip;
however, the relay will not change from energized to de-energized when the alarm status returns
to normal until the user acknowledges the pending change. Similarly, any relay in latching mode
will change from de-energized to energized if it receives a manual override Force Energized
command; however, the relay will not change from energized to de-energized when the Release
Override command is issued until the user acknowledges the pending change. The user must
check the Acknowledge and De-energize box on the Control page for a latched relay to de-
energize.
