7.5 Adjusting sensors on the control top
Adjusting the sensors
Caution!
► When actuating the valve for adjusting the sensor or for checking the
switching function, make sure that no media are inside the valve.
Caution!
► There is the risk of over-tightening the pin screw (1)! Therefore only turn
the pin screw (1) with a torque of max. 0.3 Nm up to the upper or down to
the lower limit stop of the sensor.
Hint!
Turning the spindle (A) or (B) clockwise moves the sensor upwards,
turning anti-clockwise moves the sensor downwards!
Notice
The assignment of spindle (A/B) to sensor (S1/S2) depends on
the electrical connection of the sensors at the terminal strip.
The connection is determined by the valve actuation “spring-closing” or
“spring-opening” and is described in more detail below.
► For each valve, a tolerance according to Tab. 1 must be added after the
sensor has been recorded.
Tab.1 Tolerance setting
Adjustment of sensor tolerance Δ S using spindles A and B
Valve type Spindle [turn]
from start of illumination
Seat valve 1
Bellows valve 0.5
Valve with air support: Y1 NC/ Y2 NO actuated via DO 1.5
Butterfly valve 6
Hint!
The spindle turn, not the LED brightness, is decisive for setting the
tolerances.
