Our cable glands (appendix p.14 mark 15) are designed for cables with a diameter between 7mm and 12mm. The used cables
must be able to withstand the ambient conditions (maximum temperature 70°C).
•
Remove the position indicator, unscrew the four screws and take off the cover.
SUPPLY AND CONTROL WIRING
•
Ensure that the voltage indicated on the actuator ID label (appendix p.14 mark 11) corresponds to the voltage supply.
•
Connect to earth through the exterior bolt M5 located under the cable gland (appendix p.14 mark 16). It is also possible to
connect the actuator to earth inside the actuator through the bolt M3 next to the terminal strip
(appendix p.15 mark A).
•
Unscrew the left cable gland and insert the cable.
•
Connect the wires to the terminal strip (appendix p.15 mark B) in accordance with the required control mode.
3-points modulating mode
On-Off mode (pre-set to closed)
•
Put a lacing cord around the wires (see the picture beside) and re-tighten the cable gland.
WIRING OF THE FEEDBACK SIGNAL
Our actuators are equipped with two simple limit switch contacts normally set in their
open position (NO). As per factory setting, the white cam is used to detect the open
position (FC1) and the black cam is used to detect the closed position (FC2).
This feedback system accepts voltages between 24V and 240V AC/DC.
•
Unscrew the right cable gland and insert the cable.
•
Remove 25mm of the cable sheath and strip each wire by 8mm.
•
Connect the wires to the terminal strip
(appendix p.14 mark 12) in accordance with
the diagram beside.
•
Tighten the cable gland.
SETTING OF END LIMIT SWITCHES
The actuator is pre-set in our factory. Do not touch the two lower cams in order to avoid any malfunctioning or even damage to
the actuator.
•
To adjust the position of the auxiliary contacts, make rotate the two superior cams by using the appropriate wrench.
•
Re-mount the cover, fasten the four screws and attach the position indicator.
