Troubleshooting

The Powerware 9140 is designed for durable, automatic operation and
also alerts you whenever potential operating problems may occur.
Usually the alarms shown by the control panel do not mean that the
output power is affected. Instead, they are preventive alarms intended
to alert the user. Use the following troubleshooting chart to determine
the UPS alarm condition.
The following table describes typical alarms and conditions; check the
Alarm History through the front panel for a list of active alarms. If an
alarm appears with a service code, please contact the Help Desk (see
page 92).
Possible Cause
A utility failure has occurred and
the UPS is in Battery mode.
The UPS is in Battery mode and
the battery is running low.
A battery test is in progress.

Action
The UPS is powering the equipment with battery
power. Prepare your equipment for shutdown.
This warning is approximate, and the actual time to
shutdown may vary significantly. Depending on the
UPS load and number of Extended Battery Modules
(EBMs), the Battery Low warning may occur before
the batteries reach 25% capacity. See Table 13 on
page 88 for estimated runtimes.
When utility power is restored, the UPS restarts
automatically, provides power to the load, and
charges the battery.
Wait until the battery test completes.
