DANGER!
Risk of injury via a short-circuit.
Because of technical reasons, the adjusting screw of
pressure control device unit is on a tension potential of 5V.
Use isolated tools.
Do not touch components connected with mass.
At the new pressure control device you have to set the
switch-point. For this procedure, the compressed air supply is
set to 2 bars at manometer. In the 'Service Functions' menu
the value 'P' for compressed-air control is examined. Turn at
the adjusting thread of pressure control device (between flat
connections!) until the value changes from 0 to 1.
If you set at manometer a value smaller 2 bar, then value 'P'
must be again set to 0. Adjust finely again if necessary.
Service instructions
