Pollution on the 
reflector 

The Pollutants on the reflector has to be assumed if the limit distance has 
been reached and the corresponding safety-related relays switched off, AND 
after switching off the safety-related relays a sufficiently large distance has 
been driven which should generates a larger reflector signal level than the 
specific V-level itself. 

Incomplete 
reflector view 

A permanently very small reflector view with signal level less than V-level 
BUT signal level high enough to stop the travel movement. 

Pollution Control 
signal 

The pollution warning signal is displayed with a relay (VK). The relay is 
switched on with a delay of approx. 3s up to 5s if the current signal level 
does not exceed the specific V-level during this period. 
The pollution warning signal is reset immediately if the current signal level 
exceeds the V-level again.
