29. Error ID: 02A61
Error Description: THERMIC SENS. KO
Cause A
The output signal of temperature sensor of the controller exceeds what is allowed.
Handling Method:
1. Based on the monitoring menu, compare the controller temperature, and motor
temperature or the environment temperature. Check whether the temperature displayed
on the controller is correct. If not, replace the controller.
The operating method is same as that of the error code 02A00.
30. Error ID: 02A62
Error Description: TH. PROTECTION
Cause A
1) The forklift may be overloaded.
2) The sudden brake results in a large current and causes the controller over-heated.
3) The heat dissipation performance of the electric control system is not good.
Handling Method:
1) Drop the temperature of the controller below 85°. If the fault still exists, it may be
blamed for the temperature sensor or the logic board of the controller itself. Replace
the controller at this time.
2) The poor heat dissipation performance of the controller causes that the heat can not
be transmitted timely. Improve the heat dissipation performance by applying the
heat-conducting silicone grease evenly (Between the controller and the bottom plate,
between the bottom plate and the counterweight or frame)
The operating method is same as that of the error code 02A00.
31. Error ID: 02A63
Error Description: The pump motor can not be stopped.
Cause A
Handling Method: Check whether the pump motor and the pump contactor work normally.
If not, replace the controller.
The operating method is same as that of the error code 02A00.
32. Error ID: 02A64
Error Description: The handle switch is disconnected.
The sequence from the handle limit switch S3 output to the controller C6 pin input is
wrong.
Cause A
The direction switch and accelerator have input in advance before the handle limit
switch S3 is closed.
Handling Method:
1) Check whether the accelerator has output in advance.
2) Check whether the direction switch is closed before the handle limit switch S3.
3Turn off the key. Reset handle limit switch C6 and then re-open the key switch.
33. Error ID: 02A65
Error Description: The temperature of the motor is high.
Cause A
1) The forklift may be overloaded.
2) The sudden brake results in a large current and causes the controller over-heated.
3) The heat dissipation performance of the electric control system is not good.
1) The fault appears when the temperature digital switch of the motor turns on or when
the analog sig-nal exceeds the switch-off value.
2) When the temperature of the motor reaches 150, the controller will alarm. By this
time, the forklift still can move, but the maximum current is cut and the performance
of the forklift is reduced. When the temperature of the motor reaches 160
, the
motor stalls working where it should be cooled down.
3) If the fault still exists when the motor cools down, check the circuit and resistance
value of the temperature sensor (D3/D6). If necessary, replace the controller. < Refer
