Fluidic installation

See the relevant data sheet for dimensions of TOP Control on/off and the variants of the complete
device, consisting of TOP Control on/off, pneumatic actuator and valve.

Installation of the valve

For dimensions and threads, see data sheet for the process valve.

Turning the TOP Control on/off

If, after installation of the continuous valve, the LEDs of the TOP Control on/off are poorly visible or it is
difficult to attach the cable or hoses, the TOP Control on/off may be rotated relative to the pneumatic
actuator.
Procedure:
Disconnect the fluidic connection between TOP Control on/off and pneumatic actuator.
Loosen the grub screws (hex socket SW 3) recessed into the side of the housing.
Rotate the TOP Control on/off without lifting into the desired position.
Retighten the grub screws with moderate torque.
Remake the fluidic connection between TOP Control on/off and pneumatic actuator, using longer hoses
if necessary.

Fluidic connection of the TOP Control on/off

Apply the supply pressure to connection 1 (3...7 bar, instrument air, free from oil, water and dust).
Attach an exhaust line or a silencer to connection 3.
ATTENTION!
No back pressure shall be built up as a result of the installations. This could be
detrimental to the functioning of the device! Use a hose with sufficient cross-section!

Opening the housing

Remove any lead seals or fastenings present between cover and housing.
Turn the transparent cover of the TOP Control on/off slightly anticlockwise and lift it off.
