Installation of the proximity switch
(not included in the scope of supply):
→
Fasten each of the proximity switches with two nuts (normally
included in the scope of supply of the proximity switch) into the
holes in the mounting bracket ⑥ provided for that purpose.
→
Adjust the screw-in depth of the proximity switches to match the
switching distance to the switch cams.
If necessary loosen the mounting bracket ⑥ on the nut ③
and turn it around the actuator axis.
Positioning of the switch cams:
→
Align the position of the lower switch cam ① to the lower prox-
imity switch while the actuator is in the lower end position. Fas-
tening of switch cam ① on the switch spindle ② with setscrew
⑦, tightening torque: 0.4 ... 0.6 Nm.
→
Align the position of the upper switch cam ① to the upper prox-
imity switch while the actuator is in the upper end position. Fas-
tening of switch cam ① on the switch spindle ② with setscrew
⑦, tightening torque: 0.4 ... 0.6 Nm.
→
Check the valve for function and leaks.
Note the hardening time of the Loctite before placing the
valve in operation
Fig. 18: Positioning of the switch cams
For control function A the lower end position is the rest position.
The upper end position is reached by applying pilot pressure at con-
nection 1.
For control function B the lower end position is reached by
applying pilot pressure at connection 1. The upper end position is
the rest position.
For control function I the lower end position is reached by a
pressure pulse on connection 2 and the upper end position is
reached by a pressure pulse on connection 1.
