What this code means

This warning occurs when the temperature sensor is opened (if digital) or has overtaken the threshold of 150°C (if analog).

Applies to: ZAPI ACE0 / COMBIAC0 controller.

Possible causes / checks (from the source)

Check the thermal sensor inside the motor (use the MOTOR TEMPERATURE reading in the TESTER menu); check the sensor ohmic value and the sensor wiring. If the sensor is OK, improve the air cooling of the motor. If the warning is present when the motor is cool, then the problem is inside the controller.
