NOTE
The pilot pressure of the pneumatic controller is dependent on the pressure of the flow of
medium: it must not exceed a maximum of 8 bar!
Observe the permissible pressure range given on the rating plate!
Pressure difference between Ports 1 and 3/5
≥ ≥ ≥ ≥ ≥
2 bar
ATTENTION!
ATTENTION!
When screwing down the instrument socket onto the coil, ensure that the flat seal is
well seated!
Media
