Stop (DCL voltage out of operating range OR
internal failures)

Flashing slowly
Ready (waiting for enable in CAN mode)

Single pulse mode (Mode 3)
Flashing quickly: approx 10Hz; Flashing slowly: approx 2Hz
Internal failures: temperature failure, overcurrent, gate driver fault/not ready, HW trip from overcurrent,
overvoltage, uC supply.
The state diagram of the implemented SW is shown in Figure 10. The operator has with the led’s a simple
and fast way to determine the current state without using CAN communication, where much more detailed
information is given.
