General Configuration

The cooling group configuration options are set during the commissioning of the cooling units in the

cooling group.

Caution: This procedure is to be performed by APC authorized personnel only. Changing

the settings incorrectly can cause malfunctions to your cooling unit.

Cooling unit configuration

Path: Main > Configure Unit > General

Capacity.

Set the cooling capacity of the cooling unit:

– Auto: The cooling unit automatically controls its output under normal (default) conditions.

– Max: The cooling unit runs at full capacity.

Note: Normal checks for cooling failures are disabled in the Max mode.

Start-up Dly. Enter a value for the delay. The start-up delay begins when the cooling unit is started and

initialized. The cooling unit cannot begin operation until this delay expires. Use the start-up delay to

restart equipment sequentially in your room after a scheduled downtime or a power outage.

Idle On Leak. When set to Yes , the cooling unit will enter idle mode if a Water Detection Fault

activates. Set to No to disable the cooling unit from entering idle mode if a leak is detected.

Note: The leak sensor (APC part number AP9325) is optional.

Note: There are three alarms that will cause the cooling unit to enter idle mode:

• Water Detection Fault (when Idle On Leak is set to Yes )

• Condensate Pump Fault

• Cooling Failure

See “Alarm messages and suggested actions” on page 32 for more information on alarms.
