NSTALLATION
See data sheet for dimensions of TOP Control and the variants of the complete device,
consisting of TOP Control Continuous, pneumatic actuator and valve.
Installation of the valve
The actuator must not be connected.
For dimensions and threads, see data sheet for the process valve. NOTE
NOTE
Turning the TOP Control Continuous
If, after installation of the continuous valve, the display of the TOP Control Continuous is poorly visible or
it is difficult to attach the cable or hoses, the TOP Control Continuous may be rotated relative to the
pneumatic actuator.
Procedure
➔ Disconnect the fluidic connection between TOP Control Continuous and pneumatic actuator.
➔ Loosen the fixing screws recessed into the side of the housing (hex socket SW3, see chapter System
description - Construction of the TOP Control Continuous).
➔ Rotate the TOP Control Continuous clockwise without lifting into the desired position.
➔Retighten the fixing screw with 1.2 Nm moderate torque.
➔ Remarke the fluidic connection between TOP Control Continuous and pneumatic actuator, using longer
hoses if necessary.
ATTENTION!
If theTOP Control Continuous is lifted during rotation (axially displaced), the mechanical
coupling to the position sensor mechanism may be damaged. By turning in the wrong
direction (anticlockwise), there is a risk of unhooking the position sensor mechanism.
This can be reconnected only with a special tool!
ATTENTION!
To assure leak tightness of the device (IP65), the screw for connecting TOP Control
Continuous and process valve shall be tightened with a torque not exceeding 1.2 Nm!
