Introduction
GUS 51 LED Fresnel Operating Manual

General Information
The GUS 51 is designed to maximize “throw” or “punch” by collimating the light when the beam adjustment knob is
turned clock-wise to the stop, producing an 11 degree beam angle. This setting is called the “Full Spot”, while the
other extreme of the adjustment, called ‘Full Flood” provides near uniform light intensity over a field angle of 80
degrees. This adjustability covers a ratio of 15 to 1 light intensity. Unwanted spill is controlled with barn doors. The
GUS-51 is available in CCTs of 3200 Kelvin and 5600 Kelvin which can be altered with the color frame by adding a gel.
The GUS-51 is made of machined and extruded aluminum and selectively powder coated in distinctive dark blue.
Accessories are made of cold rolled steel. Standard luminaires are equipped with detachable 10’ long power cords.
Each 120 volt cord is equipped with Edison 3 prong connectors. Other voltage models are shipped with optional plug
specified. A fused power inlet receptacle is supplied for most models. Adjacent fixtures may be powered with this
connector so long as the load does not exceed 4 amps. (fig. 2) Fuse is fast acting type 217, 6 Amp. The switch controls
the power to the one fixture. Power is indicated when the switch is lit.

1. Fused power inlet receptacle. Fuse rated at 6 A.Spare fuse in carrier.
2. 120 Vac outlet. May be used to daisy chain power to other fixtures totaling 4 Amps.
3. Analog dimming signal out for optional slave fixtures if used. If the fixture is not equipped with
DMX these BNC Connectors may used for analog signal in from optional 8 channel DMX-analog
decoder. Discontinued.
4. DMX Signal cable outlet for daisy chaining DMX signal.
5. DMX signal cable inlet.
6. Power switch to fixture. Power is on when switch is lit.
7. Local (manual) dimming switch/controller. Discontinued.
8. DMX signal present indicator light, green if signal is present, red if absent.
9. DMX Channel selector (1-512). Signal must be present for fixture to light. For a preset light level
without DMX signal set selector to between 605-699 to obtain 5-99% of light.
10. DMX Signal terminate switch. To prevent signal reflection switch #1 to “on” at last fixture in
signal chain.

Operation
1. ON / OFF - To turn on, push the lighted power switch (6) to the “on” position.
2. 10 V Dimming – Each GUS Fresnel comes equiped with 10 V analog dimming. This is designed
for us with our“DE8” DMX to 10 V converters. 10 V connections are made with BNC (3) cables, and
can be daisy-chained.
3. DMX Dimming – Each GUS Fresnel is equiped with DMX dimming. Control connection is made
via 5-pin XLR cables. Each GUS has DMX“in” and “out” connections daisy-chaining (5).
•To operate DMX, the manual dimming knob (7) must be turned all the way to the left (counter-
clockwise) to engage DMX control.
•Set DMX address via 3-digit window (9).
•DMX termination can be set via dipswitch (10).
4. Manual Dimming – 3-digit DMX address (9) must be set to“699” for full brightness. On-board
manual diming is controlled via Dimming-knob (7). Knobs should be turned clockwise to dim.
NOTE: As knob is turned clockwise the rst 1/8 turn, user will feel a “click”. This is the DMX being
disengaged for manual dimming.
5. On-board Digital Dimming – Each GUS Fresnel can be dimmed with on-board digital dimming.
This is achieved via the 3-digit window (9). The numerical range from 600 to 699 controls brightness
from 0 to 99%. EXAMPLE: A setting of 650 will establish a brightiness of 50%.
This feature can only be used when not connected to DMX.
One of the premier features of the GUS 51 is that it is thoroughly passive in the rejection of heat. No
fans or other mechanical devices are needed to insure that no damage occurs due to overheating.
This product was designed from its inceptions as an LED Fresnel, not an adaptation of an old
incandescent model. The robustness of the heat sink and the design of the external housing, along
with several proprietary design features, insures that the luminaire will not over heat in ambient air
as hot as 120 degrees F. Continuous operation in ambient air in excess of 120 degrees F (49 degrees
C) is not advisable.

Cleaning
Periodic dust removal is necessary to maintain light intensity and quality.
Caution: Never open the Fresnel xture unless the unit has thoroughly cooled.
Never touch the LED diodes even when cool as skin oils will cause damage.
Caution: disconnect power to the xture before opening.
The lensed bezel will swing open by loosening the 1/4” Allen bolt opposite the hinge. This will
expose the heat sink and the LED Cluster. Low pressure compressed air, not canned Freon is best for
dust removal. A feather duster is acceptable if not used too vigorously. Small quantities of Isopropyl
alcohol is the only acceptable cleaning agent, when applied by a soft cotton cloth. DO NOT touch or
use a cleaning agent on the diodes.
Caution: Again, make sure that the xture is cool and electrically disconnected as isopropyl alcohol
is highly ammable. When cleaning is complete, make sure the xture is dry and mechanically
closed and fastened before applying power.
Safety Precautions
Caution: Never look directly the light source
