9. Error ID: 02A17
Error Description: LOGIC FAILURE#3
Cause A
The protection function of the logic card current is faulty. Replace the controller.
Handling Method:
Restart the key switch. If the error still exists, replace the controller. The operating
method is same as that of the error code 02A00.
10. Error ID: 02A27
Error Description: U/V/W PHASE KO
Cause A
The controller and the U, V and W wires of the drive motor are disconnected.
Handling Method:
Check whether the connection among U/V/W is normal.
11. Error ID: 02A28
Error Description: PUMP VMN LOW
Cause A
At startup, the high-end voltage of the MOS tube is less than 66% of the capacitor
voltage, or the voltage is less than the required value during the operation of the
motor.
Handling Method:
1) The wiring of the lift motor is incorrect or a fault is found in the circuit of the lift
motor.
2) Check whether the positive and negative wire connection is correct.
3) Check whether there is electric leakage in the lift 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. (DATA A)

1) The forklift bumps into the barrier, making the forklift unable to move.
2) The forklift is stopped suddenly at a high speed.
If the above is irrelevant, replace the controller.

7. Error ID: 02A10
Error Description: WRONG RAM
Cause A
Find errors when performing tests for main ram: the registration address is "DIRTY". The
fault will limit the operability of forklifts.
Handling Method:
Restart the key switch. If the error still exists, replace the controller. The operating method
is same as that of the error code 02A00.
8. Error ID: 02A11
Error Description: STALL ROTOR
Cause A
The controller detected a significant difference between the two continuous speed
readings of the encoder. The internal encoder can not change the speed in a very short
time, resulting in the error.
Handling Method:
The encoder is faulty [The phase A (D1) and phase B (D4) wire is worn or broken]. Check
for the mechanical and circuit functions of the encoder. Check whether iron filings
adsorbed by the encoder cause the interference and therefore resulting in the alarm.
Power it off and then restart the forklift. Check whether manual operation causes to this
error displayed on the controller.
For example:
The operating method is same as that of the error code 02A00.
