135
Cause A
1) The internal wire of the pump motor
2) The cable connection of the pump motor
3) There is leakage between the pump motor cable and the forklift body
Handling Method:
1) The lift motor is not connected properly, or there is something wrong with the circuit
of the lift motor.
2) Check whether the positive and negative connection of the lift motor is correct.
3) Check whether there is leakage between the lift motor and the ground, and whether
the motor coil breaks.
If the above is irrelevant, replace the controller. The operating method is same as that of
the error code 02A00.

Error ID: 02A40
Error Description: AUX DRIV SHRT
Cause A
The driver of the electromagnetic brake is short-circuited.
Handling Method:
Check whether there is a short or low impedance among B5, B1, A4
and -BATT.
If the above is irrelevant, it may be circuit error of the logic card driver. Replace the
controller. The operating method is same as that of the error code 02A00.
16.
Error ID: 02A41
Error Description: WRONG BATTERY
When starting, check battery voltage with the controller and determine whether it reaches
what is allowed.
Cause A
The controller detects that the battery voltage is not within the nominal range.
Handling Method:
1) Check whether the value of BATTERY VOLSIGNE on the TESTER menu is
consistent with that on the voltmeter. If not, use ADJUST BATTERY function and
change the battery voltage to match the measured value.
2) Check if the battery is broken. If yes, replace the battery.

12.Error ID: 02A29
Error Description: PUMP VMN HIGH
Cause A
When the machine starts, the low-end voltage of MOS transistor
is 10% higher than that of normal battery or the phase voltage is 50% higher than
battery voltage.
Handling Method:
13. Error ID: 02A31
Error Description: VMN HIGH
Cause A
When the machine starts, the low-end voltage of MOS transistor is 10% higher than that of
normal battery or the phase voltage is 50% higher than battery voltage.
Handling Method:
1) The wiring of the drive motor is incorrect or a fault is found in the circuit of the drive
motor.
2) Check whether the three-phase connection is correct.
3) Check whether there is electric leakage in the motor connecting to the ground; check
whether the coil of the motor is broken.
4) Check whether the main contactor KM3 is firm, and whether the contact is worn.
If the above is irrelevant, replace the controller. The operating method is same as that
of the error code 02A00.
14. Error ID: 02A32
Error Description: Pump Controller VMN
Before the contactor is turned on, the software can check the output voltage of controller -
P and preset it at a steady state value (The forklift type option is set as LEVEL=1). If the
voltage is too low, an alarm will be reported.
