9 FAULTS DIAGNOSTIC SYSTEM
The fault diagnostic system of ACE3 controller consists of two main groups of faults:
ALARMS
Faults which cause the power section to stop, meaning the power bridge opens
and, when possible, the main contactor opens and the electromechanical brake
is applied.
Alarms are related to:
- Hardware failures in the motor or in the controller that forbid to run the truck.
- Safety-related failures.
WARNINGS
Faults which do not stop the truck or stop it by mean of a controlled regenerative
braking. The controller still works well, but it has detected conditions that require
to stop the truck, or at least to reduce its performance, without opening the
power devices.
Warnings are related to:
- Wrong sequences of operations by the operator.
- Conditions that require performance reduction in order to prevent major
failures (high temperature, …).
