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 26.
Before commissioning and during operation, regularly check the bus coupler functions
by reading the LEDs.

State Meaning
Illuminated The electronics supply voltage is greater than the lower
tolerance limit (18 V DC).
Flashes The electronics supply voltage is less than the lower
tolerance limit (18 V DC) and greater than 10 V DC.
Illuminated The electronics supply voltage is less than 10 V DC.
Off The electronics supply voltage is significantly less than
10 V DC (limit not defined).
Illuminated Actuator voltage exceeds the lower tolerance limit
(21.6 V DC).
Flashes The actuator voltage is less than the lower tolerance limit
(21.6 V DC) and greater than UA-OFF.
Illuminated The actuator voltage is less than UA-OFF.
Illuminated The configuration is OK and the backplane is working
perfectly.
Flashes The module was not configured correctly in the controller
(too few cyclic objects were mapped to the PDOs).
Illuminated Diagnostic message from module present.
Flashes Valve unit incorrectly configured or backplane function
error
Illuminated Module in the OPERATIONAL (RUN) status
Flashes Simple Ethernet connection, no POWERLINK
quickly communication

Flashes 2x Module in PRE-OPERATIONAL-2 status
Flashes 3x Module ready for OPERATIONAL (RUN) status
Illuminated Communication error
Flashes Communication aborted (module in STOP status)
Off Initialization of the Ethernet system
Illuminated The physical connection between the bus coupler and
network has been detected (link established).
Flashes Data packets received (flashes for each data packet
quickly received)
Off The bus coupler does not have a physical connection with
the network.
Illuminated The physical connection between the bus coupler
and network has been detected (link established).
Flashes Data packets received (flashes for each data packet
quickly received)
Off The bus coupler does not have a physical connection with
the network.
