What this code means

This alarm occurs when the A/D conversion of the analog inputs gives frozen value, on all of the converted signals, for more than 400msec. The goal of this diagnosis is to detect a failure of the A/D converter or a problem in the code flow that omits the refreshing of the analog signal conversion.

Applies to: ZAPI ACE0 / COMBIAC0 controller.

Possible causes / checks (from the source)

If the problem occurs permanently it is necessary to substitute the controller.
