11 LED Diagnosis on the Bus Coupler

The bus coupler monitors the power supplies for the electronic components and actuator control.
If they exceed or fall below a set threshold, an error signal will be generated and reported
to the controller. In addition, the status is displayed by the diagnostic LEDs.
The LEDs on the top of the bus coupler reflect the messages listed in Table 15.
Before commissioning and during operation, regularly check the bus coupler functions by
reading the LEDs.
