auxiliary switches, each with its own cable. Auxiliary switch S1
switches when the stem reaches its fixed switchpoint.
Auxiliary switch S2 switches when the stem reaches its
adjustable switchpoint.

Adjustment of Auxiliary Switch 2
Auxiliary switch 2 should be adjusted by a skilled person,
only.
Move the actuator to the position where the switch is to be
tripped. Cut the plastic skin with a sharp knife. Below the skin,
the adjustment screw can be accessed. Turn the screw
clockwise until the end stop is reached. Turn the screw
counterclockwise until the switch point is achieved. To check
that the required position has been set, move the actuator.
Finally, seal the adjustment hole with a piece of tape.

Electric Wiring of Auxiliary Switches
The electrical installation must comply with the wiring diagram
shown in Fig. 9. If the auxiliary switch is connected to
230 Vac, a switch with a contact gap of at least 3 mm for each
pole must be fitted with the installation.
