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.
This option is not used.
