Changing the wiring of sensor S1 and S2 in accordance with Table 2
Requirement:
® Switch off the supply voltage
Carry out the following steps:
1. Loosen both wires of sensor S1 and S2 from the terminal strip S1+/S1- and
S2+/S1- using a flat-blade screwdriver.
2.
Insert the wires from sensor S2 into terminal strip S1+ (brown wire) and S1-
(blue wire).
3. Insert the wires from sensor S1 into terminal strip S2+ (brown wire) and S2-
(blue wire).
4. Check the cables for a tight fit.
® Switch on the power supply.
Valve is not actuated!
Adjusting sensor S1
Carry out the following steps:
1.
Loosen lock nut M5 S1.1 using jaw wrench AF 8 in counter-clockwise
direction.
2. To adjust sensor S1, turn the sensor position on spindle B into the upper area
in accordance with Fig. 35. LED A may light up during this, and must go out
again after the upper switching edge (5) has been passed.
Attention: Sensor S1 must be moved from the top into the detection range (3).
3. Move sensor S1 into the detection range (3) of the target by turning it to the
left (anti-clockwise) until the green LED A starts to light up slightly (orange line
in Fig. 39).
4. To adjust tolerance depending on the valve type from the beginning of LED A
illumination, complete the necessary spindle rotation by turning to the left
(anti-clockwise) in accordance with Table 1 to add the necessary tolerance
allowance (green line in Fig. 39).
® The light intensity of LED A changes.
5. Loosen lock nut M5 S1.1 using jaw wrench AF 8 in clockwise direction.
®
Sensor S1 is adjusted with tolerance.
