In case you need to deactivate the control valve action, deactivation
may only be carried out by switching off the electric control signal, do not
disconnect the supply air!
3.2 Pneumatic connections
The electropneumatic actuator has tapped holes with G1/4 thread.
The customary male connections for metal pipes or plastic hoses can be used.
Connect the supply air to the "Supply" connection.
The required supply pressure is on the name plate.
Important:
Supply air must always be dry, oil- and dust free. Thoroughly flush the
air pipes prior to installation.
3.3 Electrical connection
1) Unthread the fastening screw of the plug connector and remove the plug
connector (3, fig.2) from the female connector on the actuator housing.
Note: Do not remove the female connector from the actuator housing. Correct
ground connection can only be guaranteed when it is in its original position.
2) Unthread the fastening screw of the plug connector and remove the rubber
gasket.
3) Lever the plug insert out of the plug connector case using a screw driver.
4) Connect the wires transmitting the control signal via the PG screw joint of the
plug connector case to the terminals of the insert which are marked 1 + , 2 – and to
its ground terminal. Secure them with screws.
5) Re-install the insert in the plug connector case. Be sure that the Pg screw joint
points to the desired direction (the plug connector case can be turned by 90°
around the insert to point to all four directions).
6) Put on the rubber gasket.
7) Plug the plug connector back in the actuator housing and secure with fastening
screw.
