12 Service and Maintenance
Service Switch and “Service“ Position
!
CAUTION
You must actuate the service switch before starting maintenance work on the
Unical 9000(X), the retractable fitting or the sensor.
We recommend installing the switch next to the retractable fitting.
The service switch moves the retractable fitting into “Service“ position and
actuates an additional safety valve. The retractable fitting is safely in “Service“
position when the yellow LED is permanently lit. Now, you can start your
maintenance work. You can remove the sensor from the retractable fitting
for replacement or regeneration. The Ceramat retractable fitting contains a
dismount guard which prevents probe movement when the sensor has been
removed.
After maintenance work has been completed, actuate the service switch to end
service mode. The retractable fitting moves into its original position (before
activation of service mode).

When the service switch is actuated, the
yellow LED blinks faster and faster until
it lights permanently to indicate that the
retractable fitting is in “Service“ position and
the safety valve has interrupted the control
air.
When the retractable fitting is in measuring
position, the yellow LED flashes.
If the safe “Service“ position is not reached,
the red LED is lit.
