Carrier CA Alarm Codes AL36

Description

The CA Controller has a built-in A-D (Analog to Digital) converter, used to convert analog readings (i.e. gas sensors, pressure sensors, etc.) to digital readings. The CA Controller continuously performs calibration tests on the A-D converter. If the A-D converter fails to calibrate for 30 consecutive seconds, this alarm is activated and will result in disabling all control units. This alarm will be inactivated upon a successful A-D converter calibration.
