Power it off. Put it aside and then restart it.
Restart it. If there is any other problems, please contact the after-sale staff.
Since the battery is running low, please charge it.
Check whether the handle connector or instrument connector is connected normally. If yes, restart for
reporting the error and contact the after-sales staff.
Since the battery is running low, please charge it.
Power it off. Put it aside and then restart it.
02A79
ENCODER ERROR02A82
The controller detects that the two consecutive speed readings of the encoder are quite different.
Since the encoder inside the system is impossible to change the speed to a large degree in a
very short time, the encoder may fail (The wiring of one or two encoders is worn or broken).
Check mechanical and circuit functions of the encoder.
The alarm may be caused by electromagnetic interference on the sensor bearing. If not the
above causes, replace the controller.
Please note:
Manual operation may also cause that the controller displays the fault, and thereby the forklift
needs to be powered off to restart.
For example:
02A84
CAN BUS KO BMS
Check whether the BMS communication circuit is normal.
canbus ko bms
Check the BMS communication circuit.
PUMP VACC NOT OK
POWER MOS SHORT
02A89
Detecting time: the standby state
The alarm displays that the voltage of the accelerator is at least1V higher than the minimum value
set in the accelerator signal（
PROGRAM VACC）.
Possible causes:
1.
The upper and lower voltage limits of the accelerator are not collected.
2.
Enter the PROGRAM VACC menu and Recollect again.
3.The controller has been broken.
02A86
Check whether positive and negative terminals of the accelerator are connected to the controller.

Check the lowering switch triggered at startup.

CURRENT GAIN
CARD TILLER
Handle communication fault .
The software will check the power bridge before the master contactor closes down wherein the
power bridge will be converted into low-end power and phase voltage will be reduced to –BATT
(rise to+BATT). If the phase voltage value doesn’t vary with the indicator, the fault signal will occur.
Replace the controller.
1. The upper and lower voltage limits of the accelerator are not collected. Enter the PROGRAM
VACC menu and Recollect again.
2. Check whether the lift speed-sensor is connected correctly.
The maximum current gain parameter is the factory set value, showing that the program of
maximum cur-rent adjustment parameter has not been enabled.
Solutions: ZAPI technicians set thecurrent gain parame-ters correctly.
BYD system is unused.
When the interlock is not closed down, the high-end driver of the electromagnetic brake outputs
high voltage.
1.
Check if any other high voltage circuits are connected to the highend outlets of the
electromagnetic brake.
2.
Otherwise, the high voltage still exists and the driving circuit inside the controller has been
broken.
LIFT+LOWER
LIFT LOW ACTIVE
CANBUS KO TILLER
1.
The forklift bumps into an obstacle suddenly, making itself impossible to move.
2.
A driver slams on the brakes when the forklift is moving at high speed.
INCORRECT START
1. The direction switch has been closed before starting.
2. The operation sequence is wrong.
3. The wire connection is incorrect.
4. If a fault cannot be eliminated, the controller shall be replaced.
PUMP INC START
The pump startup sequence is not correct. Possible reasons are as follows:
1. The lifting, tilting and other switches have been closed and before starting the machine.
2. The operation sequence is wrong.
3. The wire connection is incorrect.
4. If a fault cannot be eliminated, the controller shall be replaced.
02A93
Check whether the battery works normally.
02A94
It is not allowed to change the set of controller parameters when the controller works.
02A96
ANALOG INPUT
When A/D input by analog signals is converted into a fixed value, the fault signal appears
where delay time exceeds 400ms. The function is used to detect A/D converter fault or
analyze conversion fault of analog signal. If the fault persists, replace the controller.
