14.5 Main controller alarm analyze and solution
1)
“PUMP WARNING” lift request .
Cause
：
Fault from controller.
Solution
：
handheld unit and controller connection ,inspection alarm.
2
）
“SLIP PROFILE”
Reason
：
Choice wrong preferences of slip profile.
Solution
：
Check the parameter values of hardware setting
。
3
）
FORW+BACK
When activate back and forward request meanwhile will be happen alarm.
Solution
：
Check back and forward input connection request
（
Use TESTER functions to solve
）
Check
whether the micro switch fault or not
。
Also may be logical card fault, so when has the request switch
to ensure operation proofreading good work, its correctness, need to replace controller.
4
）
“INCORRECT START” Abnormal start
Cause
：
improper start-up alarming
Solution
：
The possible causes of the alarm (using TESTER functions to solve)
：
A) activate operation request of electricity lock switch.
B) The operator of the existing electric lock switch signals effectively.
Check the wiring, check the micro switch, may be the the order of operation is wrong , also may be the
logical card fault. So when examined above may reasons, then if any mistake, replace the controller
。
5
）
“VACC NOT OK” Accelerator fault
Cause
：
Test after the request of electric lock closed or broke 20S,When release the accelerator,
If accelerator value read from the TESTER menu higher than that read from the minimum voltage
accelerator set 1 V, fault alarm
。
6
）
“HIGH TEMPERATURE”
Reason
：
When the underpan temperature of controller is over than 85
℃
,alarming will be
happen.TheMaximum current with the temperature from 85
℃
to 105
℃
rise, reduced in
proportion
。
Current is 0 ampere when in 105
℃
.
Solution ways
：
improve the cooling device of controller. When the controller cooling,if has occurs alarm ,
may be due to temperature sensor fault or logic card fault
。
In this case,need to replace the
controller
。
7
）
“BATTERY LOW”
Reason
：
When battery electric energy less than 10% of all over voltage, cause faults.“BATTERY CHECK” ,
parameter values of battery electric quantity is not zero
。
（
reference menu SET OPTION
）
Solution ways
：
Battery charging
，
If the battery doesn't work, use voltmeter to measure thr battery voltage
value
，
compared with BATTERY VOLTAGE
values.if the two vaues can
’
t equal, “ADJUST
BATTERY” parameter
。
