11) Levelling the beam
Important
: This manoeuvre must be executed only if at the
end stroke the beam is not in perfectly horizontal position in
closing or in perfectly vertical position in opening.
- Unlock the actuator through the release screw so that the
beam opens and closes manually.
- Release the end stroke screws unscrewing the lock nuts on
the limit switch (Fig.14).
- Screw or unscrew the end stroke screws so that the beam
stays in perfectly vertical position in opening and in perfectly
horizontal position in closing (Fig.14).
- After levelling, fix the end stroke by tightening the lock nuts
on the limit switch and block the actuator.
