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.
1.
Disconnect the unit from power before installing and replacing the lamp.
2.
Loosen the knurled bolt on the back of the lamp housing and pull the housing
straight out.
3.
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.
4.
Line up the flat sides of the lamp base with the retention brackets on either side
of the socket. See
Figure 4
.
5.
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.
6.
Press lamp retainers down across lamp base and clip securely.
7.
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.
1.
Unlock the outer knob by turning it counterclockwise one turn.
2.
Gently push the outer knob from side to side and up and down until the lamp is
centered in the field.
3.
Once the lamp is centered, tighten the outer knob to lock it in place.
4.
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
°
.
1.
Loosen the beam focus knob(s) on the underside of the barrel. See
Figure 6
.
2.
Slide the lens(es) forward or backward to achieve the desired beam edge.
3.
Once the fixture is focused, tighten the beam focus knob(s).
Gel notes
For best results, al use a high quality, high temperature color medium. ETC ways
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 from the shutter handle at a 30away
°
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.
1.
Use a crosshead screwdriver to loosen the screws on the drop-in iris slot cover.
Do not remove the screws.
2.
Slide the cover completely forward, exposing the slot.
3.
Insert the iris. The flat side must be toward the shutters and the iris handle
should extend out of slot.
4.
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.
1.
Loosen the screw at the front of the light baffle. See
Figure 10
.
2.
Pull the light baffle out of the barrel.
3.
Remove the beam focus knob from the bottom of the barrel and slide the lens
assembly from the barrel.
4.
Slide the Zoom lens rear assembly into the barrel and install its beam focus knob.
5.
Slide the Zoom lens front assembly into the barrel and install its beam focus
knob.
6.
Slide the light baffle back into place.
7.
Replace and tighten the screw at the front of the light baffle.
Note:
Reverse this procedure to replace Zoom lenses with a standard lens.
