Description
If active, the automatic transfer to the static bypass is prevented.
If active, the battery charge function is disabled. In a utility power outage, the
discharge of batteries is supported.
If active, the UPS output turns off regardless of the mode of operation.
Auxiliary power, fan, communication, and rectifier/battery charger remain
functional. Restart is initiated immediately when this signal is inactive.
If active, the UPS transfers to bypass if the bypass voltage, frequency, and
synchronization are all okay.
If active, the UPS transfers to inverter operation if not prohibited by REPO or
an alarm condition.
If active, the UPS is forced to static bypass operation regardless of the
bypass status.
If active, the UPS knows that the batteries are disconnected.
These alarms can be activated separately or at the same time with other
building alarms.
Default
If active, the UPS shuts down immediately.
If active, the UPS shuts down after a user-configured delay time. Default
shutdown delay is 120 seconds. The UPS automatically restarts when the
signal changes to inactive.
If active, the UPS transfers to bypass if okay. If inactive, the UPS transfers to
the inverter when possible.
If active, the UPS knows that input is fed from the generator. Bypass is
