State

Flashing quickly

complementary to LED1

Self test, wait due to low DCL voltage. Increase

>25V for continue operation.

Flashing quickly

Off

Self test, error due to problems in passive

sequence test part

Off

Flashing quickly

Self test, error due to problems in active sequence

test part

Off

Stop (DCL voltage out of operating range OR

internal failures)

Flashing slowly

Ready (waiting for enable in CAN mode)

Flashing quickly

Run (PWM output active)

Flashing slowly

synchronize to LED1

Error (repetitive internal failures)

Flashing slowly

complementary to LED1

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.
