Code Description Cause Troubleshooting
145-TILT ERR NO CAN MSG. TILT
The internal communication with the tilt
sensor is faulty and it is not possible to
receive the tilt sensor data.
Replace controller.
146-OVERLOAD
HYD
OVERLOAD HYD The platform is overloaded.
Check the platform load. Check the
load cell calibration.
147-SERV MODE
FACTORY
OVERRIDE
The load estimation, based on the
measurements coming from the load
cells, is not calibrated.
Perform load cell calibration
procedure.
151-KSW_ERR
PLT/BASE BOTH
ON
The controller has detected that platform
and base modes are requested at the
same time.
Check the wiring and the BASE/
PLATFORM switch.
If no problem is found at the wiring
level, replace the controller.
152-ENABLE ERR
ENABLE CYCLE
REQ
Enable button is pushed but command
is not requested by the dedicated
timeout or drive/lift mode has changed
while enable button was pushed.
Release the enable button, repeat
the command sequence. Check the
joystick operatively.
153-M2 ERR
ENCODER ERROR
XX
The frequency supplied to the motor is
above 40 Hz and the feedback from the
feedback sensor has a jump greater than
value dened by parameter DIAG.JUMP
SENS in few tens of millisecond.
Check both the electric and the
mechanical functionality of the
encoder.
Check the wires crimping.
Check the mechanical installation
of the encoder, if the encoder slips
inside its housing it may raise this
alarm.
The electromagnetic noise on
the sensor can be a cause for the
alarm. In this case try to replace the
encoder.
If the problem is still present after
replacing the encoder, the failure is in
the controller. Replace it.
154-M2 ERR
OUT MISMATCH
XX
The two microcontrollers have detected
a mismatch in the way the traction motor
has being driven. The hexadecimal
value "XX" facilitates Zapi technicians
debugging the problem.
Alarm on Master microcontroller: left-
hand side motor.
Alarm on Slave microcontroller: right-
hand side motor.
Restart the machine. If the code is
still present without driving, replace
the controller.
155-M2 ERR SP MISMATCH XX
The two microcontrollers have detected
a mismatch in the speed set-point for
the motor. The hexadecimal value "XX"
facilitates Zapi technicians debugging
the problem.
Alarm on Master microcontroller: left-
hand side motor.
Alarm on Slave microcontroller: right-
hand side motor.
Restart the machine. If the code is
still present without driving, replace
the controller.
