Source Four jr and Source Four jr Zoom

Adjusting the C-clamp

The C-clamp attaches the ﬁxture to the mounting pipe and allows you to adjust the

position of the ﬁxture once it is mounted.

Tightly fasten the C-clamp to the yoke with the yoke bolt and lock washer.

Place the C-clamp on mounting pipe, then tighten the pipe bolt to secure it.

Loosen the C-clamp pan screw and rotate the yoke to the desired position.

Tighten the pan screw to lock the ﬁxture into position.

Adjusting the yoke

To adjust the ﬁxture's position, loosen the yoke locking knob and tilt the ﬁxture to

the desired position. Retighten the yoke locking knob to secure it.

Source Four jr/Zoom's two-position yoke allows you to modify the overall height of

the ﬁxture in the yoke.

To change the yoke position, remove the yoke locking knob, then remove the hex

bolts on either side of the ﬁxture.

Move the ﬁxture to the desired position (

Figure 2

Replace and tighten the hex bolts and the locking knob.

Color frame retaining clip

The color frame holder is equipped with a spring-loaded retaining clip that prevents

color frames and accessories from falling out of the holder.

Caution!

Always hang Source Four jr/Zoom with the color frame retaining clip in

the locked position.

Release the retaining clip by pushing it sideways. The retaining clip will pop open.

Insert the color frame.

Press the retaining clip down until it locks into position.

HPL lamps

HPL lamps are tungsten halogen lamps.

Verify that the HPL lamp you use is suitable for the voltage at your facility. 230V and

240V HPL lamps are available. Operating HPL lamps above their rated voltage

reduces lamp life and can cause premature lamp failure.

Installing the HPL lamp

The lamp must be installed before you use the ﬁxture.

Caution!

Always replace the lamp if it becomes damaged or thermally deformed.

Disconnect the unit from power before installing and replacing the lamp.

Loosen the knurled bolt on the back of the lamp housing and pull the housing

straight out.

Remove the HPL lamp from its box, holding it by the base.

Note:

To avoid premature lamp failure, do not touch the lamp glass. If you do

touch the lamp, clean it carefully with rubbing alcohol and a clean, lint-free

cloth before operation.

Line up the ﬂat sides of the lamp base with the retention brackets on either side

of the socket. See

Figure 4

Push down on the lamp base until the lamp seats ﬁrmly. (The top of the lamp

base will be even with the top edges of the retention brackets when it is properly

installed.)

Caution!

Improperly installed lamps cause premature lamp failure and socket

problems.

Press lamp retainers down across lamp base and clip securely.

To reinstall the lamp housing, line up the side ﬁns and the bolt hole, then tighten

the knurled bolt to secure the housing.

Aligning the lamp

Use the two concentric knobs on the rear of the lamp housing to align the lamp. The

outer knob centers the lamp within the reﬂector and locks it in position; the inner

knob ﬁne tunes the ﬁeld. See

Figure 5

Note:

The ﬁxture must be on to align the lamp.

Unlock the outer knob by turning it counterclockwise one turn.

Gently push the outer knob from side to side and up and down until the lamp is

centered in the ﬁeld.

Once the lamp is centered, tighten the outer knob to lock it in place.

Turn the inner knob right or left to adjust for optimum ﬂat ﬁeld.

WARNING!

Do not use lamps other than the HPL in Source

Four jr/Zoom ﬁxtures.

Use of lamps other than HPL will void

UL and cUL safety conformity and warranty.

Focusing the beam

On a ﬁxed ﬁeld angle Source Four jr, with a 26

, 36

or 50

lens, adjust the lens posi-

tion to focus the edge of the beam. On a Source Four jr Zoom, adjust the position of

both lenses to set the beam's spread and to focus the edge of the beam. The Zoom

lenses give you a range from 25

to 50

Loosen the beam focus knob(s) on the underside of the barrel. See

Figure 6

Slide the lens(es) forward or backward to achieve the desired beam edge.

Once the ﬁxture is focused, tighten the beam focus knob(s).

Gel notes

For best results, always use a high quality, high temperature color medium. ETC

does not guarantee performance with low temperature, saturated color gels.

Shaping the beam

You may shape the beam with the shutters, a pattern, or an optional drop-in iris (ETC

part #7062A1011). See

Figure 7

Pattern projection

The pattern holder slot is on the top side of the barrel, immediately in front of the

shutters. It accommodates the M-size pattern holder shown in

Figure 8

. The M-size

pattern holder’s handle should bend away from the shutter handle at a 30

angle. If

your pattern holder’s handle is straight, you may bend it far enough to not interfere

with the action of the shutter handle.

Use an optional donut (ETC part #7060A1037) in the accessory holder to enhance

pattern projection.

Drop-in iris slot

The drop-in iris slot is on the top side of the front barrel, immediately in front of the

pattern holder slot. See

Figure 9

. When it is not in use, a small sheet metal cover

secured with two crosshead screws prevents light leakage and retains the iris

assembly. To install an iris, follow these steps.

Caution!

Be certain the ﬁxture is not hot before installing the iris.

Use a crosshead screwdriver to loosen the screws on the drop-in iris slot cover.

Do not remove the screws.

Slide the cover completely forward, exposing the slot.

Insert the iris. The ﬂat side must be toward the shutters and the iris handle

should extend out of slot.

Slide the slot cover back toward the shutters until it meets the iris handle. Leave

enough space to move the iris handle. Tighten the screws.

Switching lens assemblies

Follow these steps to replace a ﬁxed ﬁeld angle lens with Zoom lenses.

Loosen the screw at the front of the light bafﬂe. See

Figure 10

Pull the light bafﬂe out of the barrel.

Remove the beam focus knob from the bottom of the barrel and slide the lens

assembly from the barrel.

Slide the Zoom lens rear assembly into the barrel and install its beam focus knob.

Slide the Zoom lens front assembly into the barrel and install its beam focus

knob.

Slide the light bafﬂe back into place.

Replace and tighten the screw at the front of the light bafﬂe.

Note:

Reverse this procedure to replace Zoom lenses with a standard lens.

Change lenses if they become visibly damaged to the extent that their

effectiveness is impaired, for example, by cracks or deep scratches.

Remove the lens assembly. (See

Switching lens assemblies,

above, steps 1-3.).

Remove safety screen.

Dampen a clean, lint-free cloth with vinegar or household ammonia. You may also

use water, but it will leave spots which you may remove by polishing the lens

gently with a clean, dry cloth.

Starting from the center, gently wipe the lens.

Replace safety screen.

Replace the lens assembly.

Accessories

WARNING!

Never use glass and window cleaner or any abrasive material to

clean lenses. Glass and window cleaners will stain the lens surface. Abrasive

materials (such as steel wool) will damage lenses.
