7.1  Safety instructions 
If there is a chance that safe operation is no longer possible, 
take the device out of operation and secure it against 
unintended startup. 
 
7.2  Parameterization of the device 
The LCD indicator has capacitive operating buttons. These 
enable you to control the device through the closed housing 
cover.

The transmitter automatically calibrates the capacitive 
buttons on a regular basis. If the cover is opened during 
operation, the sensitivity of the buttons is firstly increased to
