10.2 Analysis of traction related alarms displayed on console
1) WATCH DOG
It is a self-diagnosis test within the logic between Master and Slave
µcontrollers. This alarm could also be caused by a canbus malfunctioning,
which blinds Master-Slave communication. So, before replacing the
controller, check the canbus.
2) LOGIC FAILURE #3
Fault in the hardware section of the logic board which manages the hardware
current protection. Replace the logic board.
3) LOGIC FAILURE #2
Fault in the hardware section of the logic board which manages the phase' s
voltage feedback. Replace the logic board.
4) LOGIC FAILURE #1
This alarm signals that the undervoltage / overvoltage protection interrupt has
been triggered. Two possible reasons:
B) A real undervoltage / overvoltage situation happened.
C) Fault in the hardware section of the logic board which manages the
overvoltage protection. Replace the logic card.
5) VMN LOW, VMN HIGH
The test is carried out during initial diagnosis and in standby.
Possible causes:
D) problem with the motor connections or the motor power circuit; check if
the 3 phases are correctly connected; check if there's a dispersion of the
motor to truck frame.
E) fault in the inverter power section, replace the controller.
6) STBY I HIGH
The µCs verify if the feedback of current sensors device output is within the
zero current window. Possible causes of the alarm:
A) current sensor failure;
B) failure in the logic card: first replace the logic card; if the defect persists,
replace the power unit.
