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 22.
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 has not yet been configured (there is no connection
to a master).
Flashes Diagnostic message from module present
Illuminated Valve unit incorrectly configured or backplane function error
Illuminated The bus coupler exchanges cyclical data with the controller.
Flashes Waiting to establish communication with the controller
Flashes Communication was disrupted (no communication with the
master)
Illuminated Severe network problems, IP address assigned twice
Off An IP address has not yet been assigned and the DHCP service is
off.
Illuminated The physical connection between the bus coupler and network
has been detected (link established).
Flashes Data packets received (flashes for each data packet received)
quickly
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 received)
quickly
Off The bus coupler does not have a physical connection with the
network.
