 MOUNTING

4.3.3.2  Readjusting the micro switch

 cAUTION

Loss of braking efficiency!

Before checking the micro switch settings, mechanically secure the load 

against unintended movements and disconnect the brake from load!

 

►

Loosen the hexagon nut (5).

 

►

Turn the hexagon head screw (4) 

towards the micro switch (1) until it 

contacts the micro switch tappet.

 

►

Connect the measuring instrument 

to terminal 1 and 4 (normally open 

contact) of the micro switch.

 

►

Turn the hexagon head screw (4) 

towards the micro switch (1) until the 

normally open contact is closed (ON 

signal).

 

►

Turn back the hexagon head screw 

(4) until the normally open contact 

opens again (OFF signal).

 

►

Lock the hexagon head screw (4) 

with the hexagon nut (5).

Figure 9: 

Readjusting the micro switch

Check the setting again. If the ON signal does not properly switch to the OFF signal, 

repeat the readjustment.
