The adjusting buttons are located on the side of the housing and are covered
by dummy screw unions (see Fig. 1 “Components of a device”). Before the
programming or adjustment of the limit positions you must remove the dummy
screw unions with a standard screwdriver.
The electronic limit switch has the function of monitoring the position of the con-
necting rod and switching the corresponding relay contacts when the taught-in
positions are reached. These must be evaluated by your control unit and must
lead to the immediate switching-off of the motor. In the case of the optional
brake, it must be switched simultaneously (see section 4.3.1 “Optional brake”).
Furthermore, a third relay contact is provided for the display of an intermediate
position that can be randomly taught in. If the intermediate position is overrun
the relay contact changes its switching status.
Permissible adjusting range of the limit switches:
The limit switches “Retracted” and “Extended” can be adjusted via the total
stroke. You have the possibility of setting the limit positions between 0 and maxi-
mum stroke. In doing so, a minimum stroke of 10 mm has to be maintained.
