Emergency manual override


The actuator is set to its closed position in our factory and operates in electric priority. Ensure that the power supply is cut off
prior to manually operation. No declutching is required, the hand wheel has simply to be turned (appendix p.14 mark 11): Anti-
clockwise to open.

The end mechanical stops are preset to 90° and stuck (Tubetanche Loctite 577 or equivalent). It is posible to adjust then by mov-
ing the 2 screws (appendix p.14 mark 10) but you need to stick them again in order to ensure a proper sealing.
Mounting / dismantling of the cover and position indicator

For the wiring and setting of the actuator, it is necessary to remove the cover.

Mounting of the cover (appendix p.14 mark 2) : make sure that the seal ring (appendix p.14 mark 6) is correctly placed in its posi-
tion, grease of the flame path (Molydal 3790 grease or equivalent), mount the cover and tighten the 4 screws M6 (appendix p.14
mark D, torque : 6Nm).

Mounting of the position indicator (appendix p.14 mark 1) : mount the seal ring and the indicator then the window with the 4
screws M4.
