24. THERMIC SENSOR KO
The range of inverter temperature sensor is always checked and a warning is signalled
if it is out of range.
When this alarm is signalled, the maximum current of the controller is reduced to halt.
25. WAITING FOR NODE #4
The Slave has detected a failure, the Master cannot close the main contactor because
of the alarm status of the Slave (which the Master knows by the CAN-BUS line). The
failure must be looked for in the Slave controller, use the remote console to get connec-
tion to the Slave µC.
26. WAITING FOR NODE #3
The Master µC has detected a fault condition, the Slave is aware of this thanks to
canbus communication; it cannot drive the motor until the Master has resolved its
problem. The fault has to be looked for in the Master.
27. NO CAN MESSAGE #4
Master (node #3) signals that it has lost can communication with the Slave (node #4).
This fault could be determined by a problem in the truck canbus line or by an internal
problem in the controller logic card.
It is suggested to preliminary check canbus connection.
28. NO CAN MESSAGE #3
Slave (node #4) signals that it has lost can communication with the Master (node #3).
This fault could be determined by a problem in the truck canbus line or by an internal
problem in the controller logic card.
It is suggested to preliminary check canbus connection.
