American Power Conversion 2200 manual Alarms

When the unit is set for a two minute warning interval the configuration LED is brightly lit. When the unit is set for a five minute warning interval the configuration LED is dimly lit. When the unit is set for a seven minute warning interval the configuration LED is off.

5.11 Shutdown Mode

In shutdown mode the unit stops supplying power to the load, waiting for the return of utility power. If there is no utility power present, external devices (e. g., servers) connected to the com- puter interface or the accessory slot can command the unit to shut down. This is normally done to preserve battery capacity after the graceful shutdown of protected servers. The unit will scroll the front panel indicators sequentially in shutdown mode.

6.Alarms

6.1On Battery

In on-battery operation, the on-battery LED comes on and the unit sounds an audible alarm consisting of four beeps every 30 seconds. The alarm stops when the unit returns to on-line operation.

Press the on/test button during on-battery alarms to stop the beeping. This works for the current alarm only — the next on-battery alarm will have the audible indication. Shutting off the audible alarm in this way does not affect alarm reporting through the computer interface or accessory slot.

6.2 Overload

When the unit is overloaded (when the connected loads exceed maximum listed in section 12) the overload LED comes on and the unit emits a sustained tone. The alarm remains on until the over- load is removed. Disconnect nonessential load equipment from the unit to eliminate the overload.

6.3 Replace Battery

The unit emits short beeps for one minute and the replace battery LED comes on if the battery fails the self-test. The unit repeats the alarm every five hours. Perform the self-test procedure in section 5.3 to confirm the replace battery condition. The alarm stops when the battery passes the self-test.

6.4 Low Battery

When the unit’s battery is low the unit beeps continuously until the unit returns to on-line operation or shuts down from battery exhaustion. The low battery warning interval is a configuration item. See section 5.10.
