Operating principle of the command point with ID key-operated switch 
The ID key-operated switch is used primarily to set the current key position by rotation. To 
set the current key position, the rotary knob of the ID key-operated switch is turned clockwise 
or counter-clockwise. There is an opening in the rotary knob into which the ID key is 
inserted. Actuation is only possible if a valid ID key has been detected, and the authorization 
level of the relevant ID key corresponds to, or is higher than, the current key position. The 
rotary knob can be turned clockwise and counter-clockwise through 360° in 45-degree steps. 
The switch position delay is started and the temporary key position is incremented by turning 
clockwise. 
The temporary key position is indicated by the illuminated surfaces in the ID key-operated 
switch flashing green. During the switch position delay, the temporary key position can be 
changed by turning the knob clockwise or counter-clockwise. The switch position delay is 
restarted by turning the knob clockwise. During the switch position delay, the outputs are not 
yet affected by the temporary key position. After the delay has expired, the temporary key 
position is adopted as the current key position, and the outputs are switched in accordance 
with this position. 
By turning counter-clockwise, the current key position is changed to 0, and the outputs are 
switched immediately in accordance with this position. 
Note 
In a configuration with electronic module for ID
 key-operated switches for IO-Link, the 
parameters can be set via IO
-Link. 
Settings on the electronic module for ID key-operated switches 
The electronic modules for ID key-operated switches have five digital outputs. Setting of 
outputs 0 to 3 depends on the current key position and the module settings. If a valid ID key 
has been detected, output 4 is active; otherwise output 4 is inactive.
