20) HW FAULT 11/12/13
Cause

intended to enable and disable the LC driver (A16) works properly.
Troubleshooting
This type of fault is not related to external components. Replace the logic board.
21) HW FAULT 01/02/03
Cause
At each start-up the supervisor microcontroller checks that the hardware circuit
for enabling and disabling of the power bridge works properly.

22) POWER MISMATCH
Cause
The error between the power setpoint and the estimated power is out of range.
Troubleshooting
Ask for assistance to a Zapi technician about the correct adjustment of the
motor parameters.
23) SEAT MISMATCH
Cause
This alarm can appear only in a Traction + Pump configuration.
There is an input mismatch between the traction controller and the pump
controller relatively to the seat input (A6): the two values recorded by the two
controllers are different.
Troubleshooting
- Check if there are wrong connections in the external wiring.
- Using the TESTER function verify that the seat inputs are in accordance
with the actual state of the external switch.
- In case no failures/problems have been found, the problem is in the
controller, which has to be replaced.
24) STBY I HIGH
Cause
In standby, the sensor detects a current value different from zero.
Troubleshooting
The current sensor or the current feedback circuit is damaged. Replace the
controller.
