BUMPER STOP
(MDI/LED code = 0)
Cause
The two digital inputs dedicated to the bumper functionality are high at the
same time. The alarm can occur only if parameter BUMPER STOP = ON and
only if the controller is in CAN OPEN configuration (see parameter
CONTROLLER TYPE in SPECIAL ADJUST. list, paragraph 8.2.4).
Troubleshooting
-
Turn off one or both inputs dedicated to the bumper functionality.
- If the alarm occurs even if the inputs are in the rest position, check if the
microswitches are stuck.
- In case the problem is not solved, replace the logic board.
CONTROLLER MISM.
(MDI/LED code = 12)
Cause:
The software is not compatible with the hardware. Each controller produced
is “signed” at the end of line test with a specific code mark saved in EEPROM
according to the customized part number.
According with this “sign”, only the customized firmware can be uploaded.
Troubleshooting
-
Upload the correct firmware.
- Ask for assistance to a Zapi technician in order to verify that the firmware
is correct.
EEPROM KO
(MDI/LED code = 13)
Cause:
A HW or SW defect of the non-volatile embedded memory storing the
controller parameters. This alarm does not inhibit the machine operations,
but it makes the truck to work with the default values.
Troubleshooting:
Execute a CLEAR EEPROM procedure (refer to the Console manual). Switch
the key off and on to check the result. If the alarm occurs permanently, it is
necessary to replace the controller. If the alarm disappears, the previously
stored parameters will be replaced by the default parameters.
INPUT MISMATCH
(MDI/LED code = 58)
Cause:
The supervisor 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.
LOGIC FAILURE #1
(MDI/LED code = 19)
Cause
This fault is displayed when the controller detects an undervoltage condition
at the KEY input. Undervoltage threshold is 11V for 36/48V controllers and
30 V for 72/80V controllers.
Troubleshooting (fault at startup or in standby)
