Connecting an External 
Power Supply/Ballast to 
the Projection Head
The SC-1 is optionally available in a split-body configuration in which the power 
supply/ballast is separate from the projection head. This configuration is useful for 
installations where the projection area is too small to accommodate a single-body SC-1, 
or the 220-VAC source cannot be conveniently accessed from the projection area. 
The external power supply/ballast connects to the SC-1 in two places: the lamp igniter 
connection panel and the AC/lamp control input panel, as shown in 
Figure 3-21. 
Figure 3-21. External Power Supply/Ballast Connection
➤
If the power supply/ballast is internal to your SC-1 (as shown in Figure 
2-1), continue with the next step, Connecting to AC Power. Note

Connecting the Ballast to the Lamp Igniter: The external power supply/ballast 
connects to the lamp igniter via two, high-voltage DC power cables with “twist-lock” 
connectors. The connectors are color-coded and of different genders for easy 
identification (red=positive; black=negative); see 
Figure 3-22.
To connect the external power supply/ballast to the igniter: 
1. Connect the positive (red, male) DC power connector to the red (female) terminal on the 
lamp igniter connection panel. Insert the connector all the way in, then turn it 90 
degrees clockwise to lock it.
2. Connect the negative (black, female) DC power connector to the black (male) terminal 
on the lamp igniter connection panel. Insert the connector all the way in, then turn it 90 
degrees clockwise to lock it.

The Projector Status LED indicates the current operating state of the projector, as follows: 
OFF: Projection head is unplugged. 
Amber: Head is plugged in but turned off. 
Green: Normal operation. 
Red: Error preventing normal operation. 
During operation, the AC voltmeter displays the number of AC volts reaching the 
projector. Monitor this and make sure the display reads within the acceptable nominal AC 
range (200-240) at all times. If the window is dark, this indicates that the projection head is 
either unplugged or not powered up, or that inadequate, excessive or faulty AC has 
automatically “tripped” (opened) the ballast breaker and caused a shutdown.

Connecting to AC PowerThe SC-1 system includes two (2) AC power cords (one each for the DHD Controller and 
projector). 
DHD Controller: Plug the female end of one power cord into the AC receptacle on the 
rear of the DHD Controller. Connect the other end to your AC power source 
(100
 to 240 VAC). 
Projector: Similarly connect the SC-1 to a nearby AC outlet. The input voltage must be 
between 200 and 240 VAC. 
The LED status window displays an active pattern of segments to 
indicate the projector is changing its state from powered down to 
standby. At this point, the projection head is in a type of “standby” 
mode only; the light engine compartment fans are running but the 
rest of the projection head is off. “--” appears in the display when 
the projector is ready to be turned on.
 
AutoScope Lens Motor: With AutoScope-equipped projectors, a third power cord is 
provided for the lens motor. Plug the female end of the AC power cord into the AC input 
on the rear of the lens motor assembly (see 
Figure 3-19). Connect the other end to a 
110 VAC power source. 
The SC-1 requires a dedicated, 220-VAC/30A circuit. Connect 
only the SC-1 to this circuit. 
The input voltage to the AutoScope lens motor must be between 
100 and 120 VAC. Do not connect the AutoScope lens motor 
to a 200-240
 VAC power source!

2000, 3000, 4500 or 6000 watts. See 
Figure 3-24. 
Figure 3-24. Checking or Setting Lamp Size 
2. Enter the Lamp Password or the Runco service password. (You must enter a 
password unless the “Enable Password” service option has been turned off.) 
3. Press  or  to select 2000, if a different lamp size is shown. 
4. When the Status Display shows the correct lamp type, you can turn on the projector 
and lamp. 
Explosion hazard. DO NOT turn the projector on until you have 
defined the lamp size. WARNING
➤
The Lamp Size can also be changed in the Service menu (Service 
password required) if the projector is running, but the change will not 
take effect until the next power-up. Whenever possible, define the 
lamp size before igniting the lamp.

Maximizing Light 
Output
Upon powering up the projector with a newly installed/replaced lamp, use the LampLOC 
feature of the SC-1 to adjust the lamp position to help ensure optimized operation as well 
as peak brightness at the screen. You do not need to display an image on-screen to do 
this; however, the lamp must be on and the shutter open. 
To perform the LampLOC adjustment: 
1. Press MENU on the built-in keypad or TheaterMaster remote control to display the 
Main Menu. 
2. Select Lamp from the Main menu. 
3. Select LampLOC from the Lamp menu (see Figure 3-25). 
Figure 3-25. Using LampLOC to Align the Lamp 
4. For best results in most applications, select Do Auto. The motorized lamp adjustments 
will begin and, in conjunction with an internal light sensor, will take a minute or two to 
position the lamp for optimized brightness. If desired, you can operate the motors 
individually and use the Intensity reading at the top of the menu for feedback. 
Once you have done this LampLOC adjustment, the lamp will be well-centered and 
distanced correctly from the remainder of the illumination system. You can re-adjust it as 
needed at any time.

Adjusting the Picture 
Orientation
By default, the SC-1 is configured for a “floor/front” installation, in which the projector is 
installed upright and in front of the screen. If it is installed behind the screen, you must 
switch to a “floor/rear” picture orientation. To do this:
1. On the DHD Controller, press MENU and enter the Service Menu passcode.
2. Select Service from the Main Menu.
3. Select Display Device from the Service Menu.
4. Select Configure from the Display Device menu, then select Installation.
5. Choose Floor/Rear.

Primary Lens 
Adjustments
This initial optical alignment procedure is the foundation for optimizing your displays, 
ensuring that images reflected from the DMDs are parallel to and well-centered with both 
the lens and screen. 
Before you begin, properly position the 
projector relative to the screen (refer to 
Vertical and Horizontal Position on 
page 22). 
Double-check projector leveling (refer to 
Adjusting the Feet on page 31) so that the 
top edge of the image is parallel to the top 
edge of the screen.

FocusTo focus the projected image: 
1. Display a good test pattern appropriate 
for analyzing image focus and geometry, 
such as a single crosshair centered 
across the image. 
2. Rotate the knob as needed to produce a 
tightly-focused image. 
ZoomWith the projector in its permanent location, turn the lens zoom 
ring on the primary lens to enlarge or shrink the image in each 
direction as necessary.
 
Horizontal and Vertical 
Lens Shift
Using a 4.0-mm hex wrench, turn the horizontal offset knob as necessary so that the 
image fills the screen area with no keystoning. 
To access the vertical offset knob from the front of the projector, remove the round, black 
plastic cover just below the lens; see 
Figure 3-26. Turn the knob by hand to adjust the 
vertical image position. For best results, avoid extreme offsets characterized by corner 
vignettes on a white test pattern. 
Figure 3-26. Horizontal and Vertical Lens Shift Controls
For more vertical offset range, you can tilt the projector to compensate for significant 
differences in screen and lens height; refer to 
Tilting the Projector on page 31.
