5.1 Summary of diagnostic possibilities
The valve terminal offers the following possibilities for diag-
nosis and error treatment:
– Diagnosis by means of the integrated LEDs
– valve terminal status
– valve status display
– Diagnosis by means of the valve test
– Diagnosis by means of the field bus
Diagnosis by means of
module/network status
LED The combination LED for module/network status is a two-
coloured LED. This lights up or flashes either green or red,
or green and red simultaneously (orange) depending on the
operating status of the valve terminal. It indicates the status
of the module and the network.
Diagnosis by means of sig-
nal status display There is a yellow LED for each valve solenoid coil. This
indicates whether or not the relevant valve solenoid coil is
energized.
Diagnosis by means of
valve test This integrated test routine enables the valves to switch
automatically and cyclically.
Diagnosis by means of
field bus You can evaluate the Device Failure Table via the user pro-
gram.
