Setting the switch point
The following instructions describe the procedure for a Normally Open Contact (NOC).
The actual state (open or closed), can be determined using a continuity meter.
1. Loosen the switch contact set screws (1) using a
screwdriver
2. Slide the switch contact to the flow value to be
monitored. Make sure that the arrow on the switch
contact label is in exact alignment with the desired
flow value on the body scale.
3. Re-tighten the switch contact housing set screws (1)
using a screwdriver. Observe the correct tightening
torque of 0,4 Nm.
The set switch point corresponds to the switch-off point of the switch contact by decreas-
ing flow.
