Operation and Use
9.1
Notes on Operation
Type SOPA-C..
•
To prevent the contamination of the sensor modules and the measuring
nozzles, switch on the instrument air.
•
Activate the exhaust air to clean contaminated measuring nozzles.
The switching status of the valves, which are integrated in the control module and
used for activating the measuring and exhaust air, is indicated by the status LED
[Sense] and [Clean].
Type SOPA-C..-H
•
The electric manual override function for the measuring and exhaust air on
the control module can be deactivated by switching off the supply voltage for
the manual override.
Ä
The LED which indicates the ready status of the manual override is then
switched off.
9.2
Restoring Factory Settings (Restore)
By resetting to the factory settings, the current settings are lost. Note down cur-
rent settings before resetting.
1. Switch off operating voltage.
2. Press and hold the A pushbutton, B pushbutton and Edit button.
3. Switch on the operating voltage.

Using the Differential Pressure Regulator
In order to enable faster response times with low measuring distances or com-
pletely sealed measuring nozzles, a differential pressure regulator
(LRLL-1/8-QS-6) can be used instead of the vent screw. The valve function
enables the pressure to be exhausted significantly quicker than via the vent
screw.
Connecting and Checking the Differential Pressure Regulator
1. Remove the vent screw (SW 14).
2. Mount the differential pressure regulator (LRLL-1/8-QS-6) to the connection
for the vent screw (
è
Fig.3).
3. Press the CLEAN pushbutton (CLEAN = OFF) and then the SENSE pushbutton
(SENSE = ON) on the control module.
4. Make sure that no object is inserted in the area of the measuring nozzles
è
5. Turn the adjusting screw on the differential pressure regulator clockwise
(towards LOW) until no air flows from the differential pressure regulator.
6. Turn the adjusting screw on the differential pressure regulator counter-clock-
wise (towards HIGH) until air starts to flow from the differential pressure reg-
ulator.
Checking the Settings of the Differential Pressure Regulator
1. Seal the measuring nozzle (for example, clamp the workpiece).
2. Press the CLEAN key (CLEAN = OFF) on the control module.
Ä
Sensor module is supplied with operating pressure. [SUP.P] is displayed.
3. Press and hold the SENSE button (SENSE = ON) on the control module until
[SUP.P] is no longer displayed.
4. If the delay ([SUP.P] in the display) is too great, reduce the time by turning the
control valve (towards HIGH).

Maintenance and Care
1. Switch off the energy sources (operating voltage, compressed air).
2. Clean sensor with non-abrasive cleaning agents.
