Zapi DUALACE2 NEW GENERATION User Manual

Page 146/169 AFNZPxxx – DUALACE2 NEW GENERATION – User Manual
The algorithm implemented to check the main RAM registers finds wrong
contents: the register is “dirty”. This alarm inhibits the machine operations.
Troubleshooting
Try to switch the key off and then on again, if the alarm is still present replace the
logic board.
WRONG SET BAT. (MDI/LED code = 41)
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 ADJUSTMENTS list
matches with the battery nominal voltage.
If the battery nominal voltage is not available for the SET BATTERY parameter
inside the ADJUSTMENTS list, record the value stored as HARDWARE
BATTERY RANGE parameter in the SPECIAL ADJUST. list and contact a Zapi
technician.
Through the TESTER function, check that the KEY VOLTAGE reading shows the
same value as the key voltage measured with a voltmeter on pin A3. If it does not
match, then modify the ADJUST BATTERY parameter according to the value
read by the voltmeter.
Replace the battery.
WRONG SLAVE VER. (MDI/LED code = 91)
Cause:
There is a mismatch in the software versions of master and supervisor
microcontrollers.
Troubleshooting:
Upload the software to the correct version or ask for assistance to a Zapi
technician.
INPUT MISMATCH (MDI/LED code = 59)
Cause:
The master microcontroller records different input values with respect to the
master microcontroller.
Troubleshooting:
Compare the values read by master and slave through the TESTER function.
Ask for the assistance to a Zapi technician.
If the problem is not solved, replace the logic board.
SP MISMATCH XX (MDI/LED code = 15)
Cause:
This is a safety related test. The master μC has detected a mismatch in the
speed setpoint with respect to the master μC. The hexadecimal value “XX”
facilitates Zapi technicians debugging the problem.
Troubleshooting:
Check the matching of the parameters between master and supervisor.
Ask for assistance to a Zapi technician.
If the problem is not solved, replace the logic board.
