Issue:
Voltage supply to the ATS48 fan kits.

Product line:
ATS48, Altistart 48

Cause:
OHF - Overheating

Resolution:
The cooling fans are supplied with 12Vdc.  The voltage tolerance on the fans is 6-13Vdc, 315mA.  You can test operation of the fans with something such as a 9V battery, if a 12Vdc source is not available.  This should provide enough power to move the fans.
