WORKING PRINCIPLE
Products are piston type pressure switches. Applied pressure push the piston and switch is sending signal when the set pressure is reached. 3 pin connector is used to able both normally closed or open connections.
PRESSURE ADJUSTMENT
To adjust the pressure remove cover rubber and turn the adjustmet screw (in the middle) with 2 mm allen tool to wanted positions. Turning clockwise reduces the pressure and vice versa.
CONNECTION DRAWING
Normally open and closed connections shown in the drawing below.
