Zapi DUALACE2 NEW GENERATION User Manual

AFNZPxxx– DUALACE2 NEW GENERATION – User Manual Page 139/169
Cause:
Master uC is transferring parameters to the supervisor.
Troubleshooting:
Wait until the end of the procedure. If the alarm remains longer, re-cycle the key.
PEB NOT OK (MDI/LED code = 25)
Cause:
PEB terminal PIN (pin A27) is supplied by Terminal PIN (pin A24). This pin is not
connected to the battery or the voltage is different from that defined by parameter
SET POSITIVE PEB (see the ADJUSTMENTS list, paragraph 8.2.5).
This alarm can occur if AUX OUT FUNCTION or S AUX OUT FUNTION iare
active.
Troubleshooting:
Check PEV terminal (pin A27): it must be connected to the battery voltage (after
the main contactor).
Set the nominal PEV voltage in parameter SET POSITIVE PEB in the
ADJUSTMENTS list (see paragraph 8.2.5).
POS. EB. SHORTED (MDI/LED code = 84)
Cause:
The voltage on terminal PEB (pin A27) is at the high value even if the high side
driver is turned OFF.
Troubleshooting:
Verify that the parameter POSITIVE EB is set in accordance with the actual coil
positive supply (see paragraph 8.2.7). Since the software makes a proper
diagnosis depending on the parameter, a wrong setting could generate a false
fault.
Check if there is a short or a low impedance path between PEB (pin A27) and the
positive battery terminal +B. In case no failures/problems can be found, the
problem is in the controller, which has to be replaced.
POSITIVE LC OPEN (MDI/LED code = 35)
Cause:
The voltage feedback of the LC driver (output NLC, pin A26) is different than
expected.
Troubleshooting:
Verify LC coil is properly connected.
Verify CONF. POSITIVE LC parameter is set in accordance with the actual coil
positive supply (see paragraph 8.2.7). Software makes a proper diagnosis
depending on the parameter; a wrong setting could generate a false fault.
In case no failures/problems have been found, the problem is in the controller,
which has to be replaced.
POWER MISMATCH (MDI/LED code = 39)
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..
