**  Difference between switching pressure and pos-

sible reset.

***  Mean switching differential at min. and max. set-

ting

 

Deviation from the switching point during testing 
pursuant to EN 1854: air pressure switch: ± 15%.

 

If the DL does not trip at the desired switch-
ing point, correct the adjusting range using the 
hand wheel. Relieve the pressure and repeat 
the process.

Function check

 

We recommend a function check once a year.

DL..A

 

Press the test key during operation – the pressure 
switch switches.
