Here is a list of error codes for common electric forklifts:
Xilin Electric Forklift (Shunt - wound Controller)
| LED Code | Programmer Display | Fault Cause | Solution |
|---|---|---|---|
| 0,1 | NO KNOWN FAULTS | None | None |
| 1,1 | CURRENT SHUNT FAULT | 1. High - current spike caused by wrong vehicle operation. 2. Current sensor out of range. 3. Controller failure. | Turn off and then turn on the key switch again. If the problem persists, ｒｅｐｌａｃｅ the controller. |
| 1,2 | HW FAILSAFE | 1. Severe environmental interference. 2. Self - check or watchdog error. 3. Controller failure. | Turn off and then turn on the key switch again. If the problem persists, ｒｅｐｌａｃｅ the controller. |
| 1,3 | M - SHORTED | 1. Internal or external short - circuit between M - and B-. 2. Incorrect motor wiring. 3. Controller failure. | Check the wiring; turn off and then turn on the key switch again. If the problem persists, ｒｅｐｌａｃｅ the controller. |
| 1,4 | SRO | 1. Incorrect operation sequence of interlock switch, direction switch and key switch. 2. Open - circuit of interlock switch or direction circuit. 3. Too short operation sequence delay time. 4. Incorrect start - up operation sequence (SRO) or wrong accelerator type selection. 5. Incorrect accelerator adjustment. | Check the operation sequence; check whether the accelerator adjustment is correct; check whether the programmer parameters are correct. |
| 2,1 | THROTTLE WIPER HI | 1. Open - circuit or short - circuit of accelerator input to B+. 2. Accelerator failure. 3. Wrong accelerator type selection. | Correct the accelerator wiper input to make it return to the normal input range from the wrong high input. |
| 4,1 | LOW BATTERY VOLTAGE | 1. Battery voltage is lower than the minimum operating voltage of the controller. 2. Corroded battery terminals. 3. Loose battery or controller connection terminals. 4. Controller failure. | Make the battery voltage higher than the minimum operating voltage of the controller. |
| 4,2 | OVERVOLTAGE | 1. Battery voltage is higher than the maximum cut - off operating voltage of the controller. 2. The charger is still connected during vehicle operation. | Make the battery voltage lower than the upper - limit cut - off operating voltage of the controller. |
