is 45V,limitation voltage is 9V in 24 controller undervoltage
。
Static or start-up failure solutions; Static or starting may arise when voltage fault, need to check
A) The lock of the pulse signal input voltage drop (below the voltage limited voltage), the reason is
external load, like start DC/DC converter, relays and contactor switch, incentive/disconnect solenoid
。
B) If detected no voltage signal of input end, once closed electricity lock switch will be alarm,May be
controller hardware failure. That need to change the controller.
Solution ways of motor operation fault
；
arise undervoltage or overvoltage fault when motor running.
A) If alarming in traction speed up or drive hydraulic function, probably owes pressure fault, check the
battery power, power cable connection.
B) If alarming in releasing the brake period is likely to be pressure fault, check the connection and main
contactor power cable of connection

“LOGIC FAILTURE#2”Logic card fault #2
Reson
：
Logic card used in voltage feedback ,its hardware parts will have fault.
Solution ways
：
It doesn
’
t matter with the external constitute.so need to change the logic card when ha
s fault.
15
）
“LOGIC FAILTURE#3” Logic card fault #3
Reson
：
circuital current of logic card is overtop(overload) resulted in hardware failure.
Solution ways
：
It doesn
’
t matter with the external constitute.so need to change the logic card when has fault
。
16
）
“STBY I HIGH” quiescent current is overtop.
Cause
：
The controller current sensor or current feedback circuit damaged.
Solution
：
It doesn
’
t matter with the external constitute.so need to change the logic card when has fault.
18“WRONG SET BATTERY”
Cause
：
controller will test battery voltage and displays in the window to calibration of voltage value is in
nominal level when start.
Solution
：
A) “SET BATTERY” Check the controller parameter value if matchs with battery voltage of nominal
value or not
。
B) Check if the TEST MENU / BATTERY VOLTAGE indications of the parameters equal with voltage value
measured by voltmeter or not. if not equal, “ADJUST BATTERY” to adjust the voltage.
C) Change the battery.

“ANALOG INPUT”
Cause
：
When the analog input is frozen, all the signals are converted over for freezing time more than 400
milliseconds,then the fault alarm.
