MAXIMUM CURRENT=90% 88℃
MAXIMUM CURRENT=100% 86℃
Now, the max. current of controller decreases with the
increase of the max. current temperature. When the
temperature is 105℃, the current of controller decreases
to zero.
The fault appears if chopper is in the cold state:
(1) Temperature calibration parameter of logic card is
incorrect, check parameters.
(2) The internal temperature sensor of controller has
trouble and change the controller.
65
MOTOR
TEMPERAT.
High motor
temperature
If temperature digital switch of motor is turned on or
analog signal exceeds the cutoff value, the trouble is
produced. When the motor temperature reaches 120℃, the
controller gives alarm, the vehicle can move at this time.
But the max. current and performance are cut down.
When the motor temperature reaches 125℃, motor stops
working. Now try to lower the temperature of the motor.
If the fault still exists when motor is cooled, check the
circuit and change the controller if he circuit is OK.
66
BATTERY
LOW
Low capacity
of battery
If parameter of “BATTERY CHECK” for battery test is
not set as 0 and when charging capacity of battery is lower
than 15% and there is no grid on instrument, fault alarm is
given and the lifting function is locked, now charge it
timely. In case the battery has electricity, check if the
value of parameter “ADJUST BATTERY” of controller is
consistent with battery voltage.
74
DRIVER
SHORTED
Short circuit
of driver
When electric lock is close, the microprocessor will detect
if driver of main contactor is short-circuited and alarm
will be given if yes. Check if there is short circuit on the
positive pair A 16 of main contactor coil or negative pole.
Change the controller if everything is OK.
75
CONTACTOR
DRIVER
Fault of
contactor
driver
The coil of main contactor can not be normally driven and
change the controller if the coil of main contactor has no
fault.
78
VACC NOT OK
Accelerator
error
Detection time : Standby state
The alarm indicates the voltage of accelerator is 1V larger
than the min. value set in the signal scope （PROGRAM
VACC）of accelerator.
Possible causes：
(1) The upper and lower voltage limit values of
accelerator have not been collected and do it again when
entering into PROGRAM VACC.
(2) Accelerator error: Accelerator pedal possibly fails to
return or internal error of accelerator.
(3) The failure of controller
79
INCORRECT
START
Incorrect
starting
sequence
Possible causes for incorrect starting sequence:
(1) Direction switch is closed before starting.
(2)Incorrect operation sequence.
(3)Incorrect wire joining.
(4)If the trouble still can not be eliminated, change the
