FRAMING ROTATION
REPLACE MOTOR OR GEAR
1 Separate the gobo module from the
framing/iris module.
2 Remove the rack from the framing wheel as
shown here or separate the framing/iris
module. Loosen 2 set screws and pull the gear
assembly off the motor shaft.
3 Remove and unplug the motor.
4 Arrange the nuts on the new motor and turn it
so the socket faces away from you. Note that
the nuts between the motor and the plate are
oversized and used as spacers only.
5 Place the module over the motor as shown and
replace the screws loosely.
6 Put the gear assembly on the motor shaft but
do not tighten. Put the framing wheel back in
the framing module, or, replace the rack using
new M3 x 12 CS Torx screws (P/N 08050801) to
replace the taptites.
7 Position the frame rotation motor so that there
is a paper-thin gap and the slightest amount of
play between the motor gear and the rack.
Tighten the motor screws and verify that the
framing wheel turns smoothly with even
resistance through its range.
8 Center the motor gear on the rack and tighten
both set screws.
9 Plug in the new motor and reassemble the
module.
ADJUSTMENT
Frame rotation is electrically indexed: no mechanical adjustment is required.
