Operation of these relays is programmed by the user. Each relay can be selected to
become either energized or de-energized when operated, and to operate as latched, self-
resetting or pulsed.
OUTPUT TYPE
Upon being operated by any programmed feature, the relay output
contacts change state and remain in the new state. The relay can
be returned to the non-operated state only by the RESET key, the
Latched
reset logic input, or a computer reset command. This mode is used
for alarms which must be acknowledged, or to provide a lockout
function.
Upon being operated by any programmed feature, the relay output
contacts change state and remain in the new state until all
Self-resetting features which operate the relay are no longer signaling it to
operate. For a relay operated by a single feature, the output
contacts follow the state of the feature.
Upon being operated by any programmed feature, the relay output
contacts change state and remain in the new state for a
Pulsed programmed time interval called the
The dwell timer is started when the first feature causes operation
of the output relay.
