Setting of the system
Operating principle:
Pneumatic bridge
circuit
Setting of the
pneumatic bridge:
Electronic fine tuning
(if required):
Locking
0
workpiece
gap to be
monitored
backpressure
nozzles
1. Select gap distance:
• Create real operating conditions (e.g. put the workpiece into the
machining position);
• or simulate backpressure by external micrometers with integrated
nozzle.
The external micrometers with integrated nozzle (nozzle diameter
= 1.5 mm) are available under the order no. E30074.
Other nozzle diameters on request.
2. Pull and turn the setting dial until the smallest positive or negative
value is displayed. The differential pressure is then near 0 mbar.
Because of the pneumatic bridge circuit the system functions to a large
extent independently of fluctuations in the supply pressure after set-
ting.
Adjust the setpoint when the gap distance is specified.
There are 2 options:
• Teach the switch point 1 and / or the switch point 2 (TSP1/TSP2).
Or:
• Enter the displayed value (differential pressure) manually as switch
point 1 and / or switch point 2.
Mechanical securing of the setting dial:
• Remove the snap ring.
• Pierce the plastic cover (orange) in the middle of the setting dial and
remove it.
• Tighten the self-locking screw (to unlock: loosen the screw).
• Insert a new plastic cover (supplied as accessory) and reinsert the
snap ring.
