65
TION Troubleshooting:
The alarm ends when the acquisition is done.
248
NO CAN
MSG.
Cause:
This is a safety related test. It is a self-diagnosis test that checks the communication
between master and supervisor microcontrollers.
Troubleshooting:
This alarm could be caused by a CAN bus malfunctioning, which blinds master-
supervisor communication
249
CHECK
UP
NEEDED
Cause:
This is a warning to point out that it is time for the programmed maintenance.
Troubleshooting:
Turn on the CHECK UP DONE option after that the maintenance service.
250
THERMI
C SENS.
KO
Cause:
The output of the controller thermal sensor is out of range.
Troubleshooting:
This kind of fault is not related to external components. Replace the controller.
251
WRONG
SET BAT.
Cause
At start-up, the controller checks the battery voltage (measured at key input) and it
verifies that it is within a range of
±
20% around the nominal value.
Troubleshooting
- Check that the SET BATTERY parameter inside the ADJUSTMENT list
matches with the battery nominal voltage.
- Through the TESTER function, check that the KEY VOLTAGE reading shows
the same value as the key voltage measured with a voltmeter on pin A1. If it does
not match, then modify the ADJUST BATTERY parameter according to the value
read by the voltmeter.
- Replace the battery.
252
WRONG
ZERO
Cause:
At start-up the amplifiers used to measure the motor voltage sense voltages above 3
V or below 2 V.
Troubleshooting:
This type of fault is not related to external components. Replace the logic board.
253
FIELD
ORIENT.
KO
Cause
The error between the Id (d-axis current) setpoint and the estimated Id is out of
range.
Troubleshooting
Ask for assistance to a Zapi technician in order to do the correct adjustment of the
motor parameters.
254
EB.
DRIV.SH
RT.
Cause:
- The EB driver is shorted.
- The microcontroller detects a mismatch between the valve setpoint and the
feedback at the EB output.
