4.2.1 Fitting the end position sensor
Remove the screws (34) and the window (35). Remove
the white indicating element 833.1) and fit instead the
sensing element (see item 4.2) (100.1 or 100.2) with
the screw (33.2) fitted into the mounting plate (33). Refit
the window (35) together with the brackets (101). Refit
the screws (34). Before tightening the screws, hold the
brackets slightly apart, so that the distance between them
will be at least 18 mm. Fit the selected sensor (103) and
set the required end poistion. The sensor can be adjusted
in height as well as sideways. Finally, fit the protective
cover (102), and secure it in position with its Velcro
locking.
4.3 Junction box
The actuators have mounting holes for fitting a junction
box. The junction box (see Fig. 17) contains terminals
for connecting one solenoid valve and two end position
sensors. The junction box is made of cast aluminium
and has a tightly-seating cover. Degree of protection: IP
65. If the junction box is factor-fitted to the actuator by
NAF, it also contains a wiring diagram for the appropriate
sensors.

4.4 Solenoid valves
Sizes 0-3
The actuators have mounting holes in accordance with
NAMUR (Fig. 18). Solenoid valves conforming to this
standard can thus be mounted directly on the actuator.
However, first contult NAF if both solenoid valves and end
position sensors are to be fitted.
