Table 4-2 TRACTION CONTROLLER
Error Message Possible Cause Fault Elimination
Code Error Text
99 SLIP PROFILE This is an error on the choice of
the parameters of the slip pro-
file.
Check the value of the parameters in the hard-
ware setting menu.
80 FORW+BACK This alarm occurs when both the
travel (Fwd and Bwd) are
active at the same time.
Check the wiring of the Fwd and Rev travel
demand inputs (use the readings in the
TESTER to facilitate the troubleshooting).
Check the microswitches for failures.
A failure in the logic is possible too. So, when
you have verified the travel demand
switches and wiring are correct, it is neces-
sary to replace the controller.
79 INCORRECT
START
This is a warning for an incorrect
starting sequence.
The possible reasons for this alarm are (use
the readings in the TESTER to facilitate the
troubleshooting):
• A travel demand was active at key-on.
• Presence man sensor was active at key-on.
Check the wiring. Check the micro-switches. It
could also be an error sequence made by
the operator. A failure in the logic is possi-
ble too; so when all of the above are
checked and nothing was found, replace
the controller.
78 VACC NOT OK The test is made at key-on and
after 20 sec that both the travel
demands have been turned off.
This alarm occurs if the
ACCELERATOR reading in the
TESTER menu is 1.0V higher
than PROGRAM VACC min
acquisition when the accelera-
tor is released.
Check the mechanical calibration and the
functionality of the potentiometer.
62 HIGH TEM-
PERATURE
This alarm occurs when the tem-
perature of the base plate is
higher than 85  . Then the max-
imum current decreases pro-
portionally with the
temperature increases from
85  to 105  At 105  the Cur-
rent is limited to 0 Amps.
Improve the air cooling of the controller. If the
alarm is signalled when the controller is
cold, the possible reasons are a thermal
sensor failure or a failure in the logic card.
In this case, it is necessary to replace the
controller.
