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
disabled; the automatic battery test is disabled.
