Before proceeding in setting the operator, bleed it.
Start the operator after having checked the setting
of the pressure relief valves, move it to stroke end
either in open or close position and, acting on the
screw (see fi g. C18), lock and release the operator
a dozens of times.
3.11.2 Adjusting the brake in close
position
!
Warning
The operator is standard supplied with cut-out
brake.
For an easy adjustment, proceed as follows:
• Retract the rod inside the operator by means of the
manual release device or by powering the operator
opening.
• Tighten the slow-down setting screw (C19 pos. 1)
by rotating clockwise.
• Power the operator closing (rod extension) for a
longer time than the one necessary to complete the
maneuver. The rod movement stops.
• Rotate the slow-down setting screw (C19 pos. 1)
counter-clockwise. Rotate slowly for max. 4 complete
turns until the rod starts moving again.
• Adjust the slowing-down as required by rotating the
screw of half-turn.
