Issue:
This dcoument describes the issues that can cause an ACOA5XX cooling failure.

Product line:
ACOA5XX.

Environment:
All Serial Numbers.

Cause:
Supply Air Temperature> 90 F and Cooling Output < 4 kW.

Resolution:

Supply Air Temperature> 90 F and Cooling Output < 4 kW

OA will shut down

OA will restart after 5 Min

If conditions still exists after 60 seconds OA will shut down.

t_f = 300^oF* sec/ t_sup - 90oF

Where

T_sup is the average supply air temperature in ^oF
