15) INCORRECT START AL 79 MDI 2 LED FLASHES
Forwards/reverse, tiller, quick inversion present at key-on; traction running request
given before tiller/seat.
16) THERMAL PROTECTION AL 62 MDI 7 LED FLASHES
Temperature alarm activated if the temperature is >+75°C in which case the
maximum armature current is reduced linearly until it reaches nil at a threshold
temperature of 90°C; the speed is reduced to 60%; the alarm is reset only if the
temperature drops to below 70°C. If the temperature falls to below –10°C the
maximum armature current is reduced by 20%.
17) EEPROM OK AL 13 MDI 1 LED FLASH
Fault in the memory area where configuration parameters are recorded. If the fault
persists when the key is turned off and turned on again, replace the EEPROM and
check the connections between the EEPROM and the µP. If the alarm no longer
occurs, remember that the previously recorded parameters have now been
cancelled and replaced with default values.
18) PEDAL WIRE KO AL 86 MDI 4 LED FLASHES
Indicates that the negative wire of the potentiometer is disconnected.
Possible causes:
a) one of the potentiometer wires is disconnected;
b) the potentiometer is not wired correctly;
c) the potentiometer is faulty.
19) CURR. PROTECTION AL 96 MDI 5 LED FLASHES
Current protection; if for any reason the current exceeds the calibrated values, the
microprocessor disengages the functions until the current drops to the required
value.
AL 98 on MDI: MDI and chopper have different counter.
