LC display of electronic base modules
The electronic base modules (part of the valve unit) feature an LC
display for displaying the device status. The switching position
and possible fault states of the outputs are graphically presented
on the display. Depending on the module configuration, further
information can be displayed, e.g.
– Position of the actuator assigned to the output
– Measured value of the pressure sensor of a connection unit
(PSU-...-PS).
Arising messages (information, warnings, faults) appear as text
on the LC display. The text message is displayed alternately with
the graphical display of the channel status.
Electronics modules with eight valve slots are equipped with
two LC displays. In this case, numbering of the channels occurs
across both displays.
Example:
