DUAL AC2 TRACTION SLAVE UNIT
CODE ALARM
DESCRIPTION
61
WATCH - DOG
It is a self-diagnostic test within the logic between the Master and Slave
µcontrollers. This alarm could also be caused by the canbus malfunctioning
or data transmission interferences.Therefore, before replacing the Dual AC2
unit check the correct canbus functioning and the general turck insulation.
62
EEPROM KO
Fault in the area of memory in which the adjustment parameters are stored;
this alarm inhibits the 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 previously stored have been deleted and replaced by the default
values (see adjusting tables).
63
LOGIC FAILURE #3 Logic defect. Replace the traction unit.
64
LOGIC FAILURE #2 Fault in the hardware section of the logic boardwhich manages the phase
voltage feedback. Check the power cables connected to the left traction
motor. If the fault is not caused by external reasons, replace the Dual AC2
traction unit.
65
LOGIC FAILURE #1 This alarm signals that the interruption of protection against undervoltage /
overvoltage has been triggered. The possible reasons are:
a. Real battery undervoltage / overvoltage, or voltage loss after tht ignition
key or after the battery connector
b. Fault in the hardware section of the logic board which controls the
overvoltage protection. Logic defect. Replace the traction unit.
c. The alarm appears also when one or more phases of the left traction
motor doesn't present a correct insulation. Check the motor insulation
(with deconnected battery): it must be higher than 1 Mohm. Otherwise
check the power cables insulation to the motor.
66
VMN LOW
Failure in the VMN test. This test starts when the ignition key is turned ON.
The alarm appears if there is a creepage on one or more phases; check
the connections of the 3 power cables from the Slave unit to the left traction
motor and the cables condition also. In order to point out if the fault is
produced by an internal or external cause invert the connection of the
traction motors. It means Slaveto right motor and Master to left motor.
If the problem jumps on the Master it means that the left traction motor is
demaged, otherwise replace the traction unit.
67
VMN HIGH
Failure in the VMN test. This test starts when the ignition key is turned on.
The alarm appears if one or more pover cables are not connected; check
the connections of the 3 power cables from the Slave unit to the left traction
motor and the cables condition also. In order to point out if the fault is
produced by an internal or external cause invert the connection of the
traction motors. It means Slaveto right motor and Master to left motor.
If the problem jumps on the Slave it means that the right traction motor is
demaged, otherwise replace the traction unit.
68
CONTACTOR OPEN Failure on the contactor driver.
- Check main contactor coil and relevant wirings.
69
STBY I HIGH
Failure on the current sensor.
- Replace the traction unit.
