17. EEPROM KO
Fault in the area of memory in which the adjustment parameters are stored; this alarm
does not inhibits truck operation, but the controller will use default parameters. If the
defect persists when the key is switched OFF and ON again, replace the logic. If the
alarm disappears, remember that the parameters stored previously have been can-
celled and replaced by the default values.
18. HIGH TEMPERATURE
Master or Slave or both temperatures are greater than 75°C. The maximum current is
reduced proportionally to the temperature increase. At 100°C the max current of both
inverter is reduced to zero.
If the alarm is signalled when the controller is cold:
a) thermal sensor failure;
b) failure in the logic card.
19. MOTOR TEMPERATURE
This warning is signalled if right or left or both motors temperature switches open
(digital sensor) or if the analog signals overtakes the cut off level. If it happens when the
motor is cold, check the wiring. If all is ok, replace the logic board.
20. BATTERY LOW
If the "battery check" option is ON, a battery discharge algorithm is carried out. When
the charge level is 20% , this alarm is signalled and the current is reduced to the half of
the programmed level.
21. VACC NOT OK
The test is made in standby. This alarm indicates that the accelerator voltage is 1V
greater than the minimum value programmed by the PROGRAM VACC function.
Possible causes:
a. the potentiometer is not correctly calibrated;
b. the potentiometer is defective.
22. INCORRECT START
This alarm signals an incorrect starting sequence. Possible causes:
a. Fw or Rev or Enable microswitch failure;
b. error in sequence made by the operator;
c. incorrect wiring;
d. if the default persists after checking the harness, replace the logic.
23. FORW + BACK
The test is carried out continuously. An alarm is signalled when a double running re-
quest is made simultaneously. Possible causes:
a. defective wiring;
b. running microswitch failure;
c. incorrect operation;
d. if the defect persists, replace the logic.
