City Theatrical Follow Spot Yoke
Getting Started with the City Theatrical Follow Spot Yoke for source four
LED
Congratulations on the purchase of your City Theatrical Follow Spot Yoke for
Source Four LED. The City Theatrical Follow Spot Yoke is a professional
quality device that can provide smooth pan and tilt operation to your Source
Four LED. A heavy steel yoke gives mass and prevents vibration, and ball
bearings on the pan and tilt create extremely smooth movement, even on very
long throws.
The 1502 City Theatrical Follow Spot Yoke can be configured for use with the
Source Four™ Series 1 and Series 2 LED fixtures as well as the ETC ColorSource
Spot. All lenses from 5º to 50º can be used. A track allows the lighting
fixture and any accessories to be perfectly balanced for ease of
operation.
Mounting your Follow Spot Yoke
The City Theatrical Follow Spot can be mounted in a variety of ways. The
bottom of 1503 follows spot yoke has a 5/8” male pin and can be attached to
any holder which will accept the 5/8” male pin. If needed the Pin can be
removed and threaded onto any 1/1/2” NPT pipe thread.
Example mounting Method:
Preparing Your Lighting Fixture
If you are planning to use a 14º-50º or a 10º Source Four, you will need to
remove the shutters from the lighting fixture. This is not necessary, but may
be desirable for a 5º Source Four to prevent the shutter blades from
accidentally being moved during operation. Remove the shutters by removing the
four machine screws which hold the two halves of the Source Four barrel
together and exposing the shutter, pressure plate, and shutter spring parts.
Remove the shutter blades, but reinstall the pressure plates and springs. Do
not reinstall the existing four machine screws into the barrel. Go on to the
next step:
Two Angle Brackets allow your Source Four to be installed in the Follow Spot
Yoke Source Four LED. Replace the four ETC machine screws with the enclosed
8-32 x 1 ½” pan head Philips machine screws into the Source Four’s existing
8-32 hex nuts.
Next, install the two Tee Slot Extrusions using the enclosed #8-32 x 3/8” flat head Philips machine screws (three screws per extrusion) as shown in the illustration below.
Note: If you experience difficulty installing new #8-32 x 1 ½” screws it may be due to incompletely threaded holes on the Source Four barrel. Threads can be formed completely with the following steps:
- Remove the bottom half of the barrel, and locate the threaded holes in the barrel.
- With the top half of the barrel removed Screw the original ETC machine screws into the hole completely then remove. This will form the remaining threads.
- Reassemble barrel and insert longer 1-1/2” machine screws into completely formed threaded holes.
Installing the Source Four into the Follow Spot Yoke
Note the two Tee Blocks that slide into the Tee Slot Extrusion. Using a 3/16”
Allen key, slightly loosen the two 3/8” x ½” socket head shoulder screws to
free the Tee Blocks. Carefully insert the Tee Slot Extrusions onto the Tee
Blocks. Tighten the tilt handwheel.
Temporarily tighten the shoulder screws
Install four 4-40 x ¼” pan head machine screws, one at each end of each Tee
Slot Extrusion.
These screws serve as safety devices to prevent the Tee Blocks from
accidentally slipping out of the Tee Slot Extrusion track.
Install the Lens Tube into the Source Four
Install the Lens Tube into the Source Four and install the two #10-32 screws (one plastic thumbscrew and one Philips machine screw) that hold the Lens Tube to the lighting fixture. Plug in the lighting fixture into a switch or dimmer and dress the cable to ensure that it does not restrict the yoke’s movement or its balance. Turn on the lighting fixture and adjust the sharpness of the beam to the degree that you think is appropriate.
Balance the Lighting Fixture in the Yoke
The lighting fixture can be adjusted forward or backward in the Tee Slot Extrusion to establish a perfect balance point. To test the balance, carefully loosen the tilt locking knob and feel if the fixture is front heavy or back heavy. To adjust the balance, loosen the two shoulder screws and evenly push the fixture forward or backward in the Tee Slot Extrusion until it balances exactly. Lock the shoulder screws again. Test and repeat if necessary.
****Adjust balance as needed
