8) “EEPROM KO”EEPROM damaged
Reason
：
Built-in Storage controller parameters “eeprom” damaged or hardware or software fault. This
alarm will not banned the operation of trucks and works according to default.
Solution ways
：
Try to perform "CLEAR EEPROM" clear memory command (portable unit)
。
Disconnect the electric
lock switch then closed, and check the result
。
If the alarm persists, need to replace controller
。
If the alarm disappear, previously stored parameter values are replaced by default values
。
9
）
“MOTOR TEMPERATURE”
Reason
：
The temperature probe has broken down (numeric type )or more than 150
℃
(
analogue type)
Check the temperature of the motor
（
Read “MOTOR TEMPERATURE” motor temperature value
through TESTER menu
）
；
Check the sensor resistance and sensor wiring
。
If the sensor no
problem, improve the air cooling device, if still happen alarm, may be motor internal
malfunction
。

）
“THERMIC SENSOR KO”
temperature probe fault
Cause
：
Controller of the temperature sensor output beyond the range.
Solution
：
This type of fault form has no relationship with external constitute,change the controller.
。

）
“CHECK UP NEED”Sevice warming
Reason
：
It is time to examine and repair.
12
）
“DATA ACQUISITION”
Reason
：
Current gain
Solution ways: Obtained
13
）
“PEDAL WIRE KO”
REASON
：
The connection of two input terminals of continuation detection potentiometer. two input
terminals connection of software which is testing accelerator potentiometer continuation. Testing
including induction diode on both ends of the voltage drop,the two s is NPOT(AMP SAAB ADAPTING
PIECE CNA#23 end) and GND
，
Cascaded with potentiometer
：
If potentiometer is not connected to the
ppot end or npot end
，
no current through inductive diode, so to the voltage of npot connection
slumped
。
When the voltage of the npot is below 0.3 v, or higher than dc2v, alarm happen.
。（
Also can test the
damage of the diode's damaged condition
）
Solution ways
：
Inspect for the connection between valtage NPOT and potentiometer.
14
）
“TILLER OPEN”
Reason
：
Alarm
：
After 30s ,main contactor disconnection when release the bat-handle switch.
Solution ways
：
when active the next operation request,alarm disappear.
15
）
“CURRENT GAIN”
Reason
：
obtained parameter values of maximum current is default
，
This suggests that haven't execute
the maximum current to adjust program.
