ELECTRICAL CONNECTIONS AND CONTACT SETTINGS
The contact is connected in series to the desired device (solenoid valve, etc.).
CNL 200 & CNL 250:
On metallic models, the threshold is adjusted by moving the contact stem. Loosen
the locking screw (hexagonal female 1.5) and move the stem until the red arrow is
visible at the entrance if closed contact is desired, and, the blue arrow if the open
contact is desired. Once the adjustment has been made, tighten the locking screw.
Fine adjustment of the switching point can be carried out between limit points 2 and
3 of the adjustment range.
Move to arrowhead (2) → The switching point is advanced.
Move to the base of the arrow (3) → The switching contact is delayed.
After adjusting the switching point, we recommend sealing the locking screw of the
stem with a suitable varnish.
CNL 320 & CNL 450:
On the PPH models, the threshold is not adjustable, in all cases, it is done when the float is in line with the controller. The threshold, or for an
increasing, or a decreasing level, is chosen according to the orientation of the controller.
In position (A): The contact detects when
level is rising.
In position (B): The contact detects when
level is going down
