MECHANICAL INSTALLATION
The yoke is normally hung in vertical position, on trusses
or pipes of 50 mm diam.
The pipe has to be strong enough to carry the weight of
the yoke(s) and rigid enough to avoid oscillations during
the use that can reduce the precision of the focusing and
disturb the position of the other units already focused.
If you wish to install the yoke on the floor instead of
hanging it, you can fix it by using a special base plate
that can be ordered as an option.
The yoke is foreseen to work always in vertical position
(either from horizontal pipes or on horizontal floor).
Don’t install it in different positions in order to avoid
overload of motors and of ball bearings.
Even though the motors are protected with a clutch
and electronic cut-off if the yoke hits an obstacle, it is
important to allow reasonable space around the fixture.
Don’t forget to connect the safety rope, as well if
required by the local country safety regulations.
MOUNTING OF THE VIDEO PROJECTOR ON THE
YOKE
The yoke is equipped with a rectangular plate screwed on
the mobile part of the yoke that can be easily removed .
The video projector has to be fixed on this plate..
Normally it can be done as follows:
• Unscrew the plate from the yoke
• Take away the adjustable feet on the bottom of
the video
• Put the video on the plate as it should be later
mounted.
• When you define the position of the video on the
plate, if the connectors of the video are on the side
of the fixture don’t forget to leave room enough
for their insertion;
• Mark on the plate the position of the holes of the
removed feet.
• Drill the plate in correspondence of these points
with holes that should be approximately of the
same diameter of the holes on the video.
• Fix the plate to the bottom of the video with screws
of the same diameter and pitch of the original feet,
together with lock washers.
• Tighten them strongly in order to be sure that the

INTRODUCTION
ARC System ( Automated Remote Control system) is a
family of motorised yokes for remote control of stage
and studio luminaires , video projectors, and many
other products.
ARC Video is the version studied for the remote
control of video projectors.
The standard controlled parameters are:
• Horizontal (X) movement (pan) for more than 370°
• Vertical (Y) movement (tilt) until 270°
All the above functions are controlled through
DMX 512
digital signal.
Being silent and accurate, Arc can be installed both
on the stage and in the auditorium, and operated even
during the show without disturbing the audience.
