Flow switch VHS07 M2 KKTKR01
Type of Contact
The reed switch unit of the switch provides 2 different types of contact:
1.
working contact (make contact):
„RED“ arrow to switch unit
2.
break contact (breaker):
„WHITE“ arrow to switch unit
The following table explains the two types of contacts:

If not requested otherwise, the switch unit is set to 'working contact' on delivery, i.e. the reed contact breaks when the
flow rate decreases under the adjusted set point.
Adjusting the Reed Switch Unit
To adjust the reed switch unit, open the junction box of the
switch head (fig. 3).
Then loosen the locking screw (Allen screw 2,5 across flats with
brass or stainless steel version and cross head with plastic
version) and move the reed switch unit so far that with set
'working contact' (fig. 4) the red arrow (or with set 'break
contact' the white arrow, fig. 5) is visible at the entry of the
switch units guiding.
Fig. 3
After adjustment tighten the locking screw again.
Close the snap-in cover.
When a fixed switch point was set at work, then there is no adjustment of switch unit.
