American Power Conversion DX Benutzerhandbuch

The Module Control options are configured and tuned during the commissioning of each Module. 

Caution: The settings in the Module Control menu are defined at the factory. Changing 
the settings incorrectly can cause serious malfunctions and damage to your System. Only 
qualified service personnel should make changes to these settings.

Note: The System must be on and the blowers must be operating to calibrate the airflow 
manually. If either condition does not exist, the display will prompt you to turn on the 
System and blowers.

Set the nominal coil differential pressure.

Adjust the frequency of the blower.

Displays the coil differential pressure. The coil differential pressure changes as the blower 

frequency is adjusted. The Std Dry value in the table below gives the recommended coil differential 
pressure for the FM DX Precision Air Conditioner.

Set the nominal coil differential pressure.

Start the automatic calibration. If calibration is in progress, this line displays: Abort. 

Displays the coil differential pressure. The coil differential pressure changes as the blower 

frequency is adjusted. When the Coil DP values match the Nom Coil DP value, the System will 
display Calibration Complete. If the System cannot align the two values, the System will display 
Calibration Failed after two minutes. You must manually calibrate the airflow if automatic 
calibration fails.
