What this code means

The outputs of the amplifiers (used to measure the traction motor voltage) are checked to be included into a range . This alarm occurs when the voltage signals >3V or <2V at the init.

Applies to: ZAPI ACE0 / COMBIAC0 controller.

Possible causes / checks (from the source)

This type of fault is not related to external components; replace the controller. 29) ”EVP1 COIL OPEN” Cause: This fault appears when the LOWER EVP1 output is used (parameter “EVP TYPE” in “SET OPTION” menu is set ANALOG or DIGITAL) but no load is connected between the output and PAUX positive. Troubleshooting: A) It is suggested to check the harness, in order to verify if EVP1 coil is connected to the right connector pin and if it is not interrupted. B) If, even connecting the coil to the right pin or replacing it, the alarm is still present than the problem is inside the controller logic board, replace it. 30) ”EVP2 COIL OPEN” Cause: This fault appears when the EVP2 output is used (paramet
