9.1 Setting of the internal limit switches
Ensure that the mains supply is secured against accidental switching-on!
The limit switches are pre-adjusted in the factory. An additional adjustment of the two lower switching
cams is normally not necessary. If you wish to adjust the limit switches yourself, please follow the these
instructions:
Run the actuator by using the hand wheel in direction to the closed position until the required position
is reached.
Turn the cam of the CLOSE limit switch (Figure 9, Pos. D) with a suitable screw driver (4 mm blade width)
clockwise until you hear the micro switch click.
Run the actuator by using the hand wheel in direction to the open position until the required position is
reached.
Turn the cam of the OPEN limit switch (Figure 9, Pos. C) with a suitable screw driver (4 mm blade width)
counter-clockwise until the micro switch is heard to click.
Check the switching position and repeat the adjustment if necessary.
