Communication
The RMP II contains a local horn and the backlit status indicators listed in
Table 37. RMP II Status Indicators
SYSTEM NORMAL
The UPS is energized (either with utility power or battery
backup) and is supplying conditioned power to the critical load.
NO REDUNDANCY
This indicator applies only to parallel systems when one cabinet
is not functioning.
ON GENERATOR
The UPS input and bypass are being supplied by the power from
the generator instead of from the utility power.
ON BYPASS
The bypass source is supplying the critical load. Usually this
means that the UPS is not energized. The load is not protected
in Bypass mode, and a horn sounds after 30 seconds.
UPS ALARM
The UPS system is issuing an alarm. Conditions that affect the
current UPS mode are indicated by the indicators and horn on
the UPS.
ON BATTERY
The UPS battery backup is supplying the critical load. The utility
power is either interrupted or out of specification. The SYSTEM
NORMAL indicator is also illuminated.
BYPASS UNAVAILABLE
The UPS system is in Online mode, but a bypass source is not
within specification. A horn sounds after 30 seconds.
SHUTDOWN IMMINENT
The UPS is preparing to shut down because the UPS is in
Battery mode and the DC voltage is approaching its low limit.
This indicator is accompanied by a horn.
