error codes

2 diagnostic LED diodes, traction and pump foult codes separately

RED LED Description
1 BLINK EEPROM error, wrong parameters, watchdog circuit has been trigerred
2 BLINKS Incorrect start, wrong sequence - eg. keyswitch, directions, accelerator, function switch active after key-on
3 BLINKS Wrong VMN output voltage, short to B-
4 BLINKS Accelerator high in standby or lift potentiometer not calibrated
5 BLINKS Error in read motor current, sensor inside controller
6 BLINKS Malfunction of contactor driver circuit, short-circuit
7 BLINKS Temperature too high, more than 80 deg. C
8 BLINKS Contactor don't open or VMN voltage is high in stanby
9 BLINKS Contactor contact stucks
32 BLINKS Battery charge low, less than 10%
ON Forward and reverse direction inputs are both active
