3.
Connect wiring to the control system as shown in the diagrams to the right. (If
flush mounting, feed the cable through the base before terminating.)
4. Make sure the footcandle range jumper is in the correct position for the
expected light level. (Refer to “Range Adjustment” below, and the control
system instructions for information about photocell range adjustment.)
5. Return the base to the lens assembly.
a) Align the arrow and sun icon inside the base with the lens.
b) Use gentle pressure to snap the parts together.
6. Power-up the controller. Verify the photocell wiring by reading the controller
display. As you cover and uncover the photocell, the reading should change.
The controller reading shows the minimum value of the programmed range if
the light level is below the range, or if the photocell is not properly connected.
Range Adjustment
The 2-pin jumpers next to the wiring terminals set the light level range for the GLS-LOL. In
most applications, the default range of 30 to 3000 footcandles is appropriate. If the range
needs to change (e.g., 3-300fc for darker applications, 60-6000fc for skylight applications)
be sure the control system programming is adjusted accordingly.
MOUNTING
After selecting a location and wiring it to the control system, test for the optimum lens
orientation before permanently mounting the photocell.
The GLS-LOL comes with a circular piece of double-sided foam adhesive tape. You can use
this tape to temporarily mount the photocell during placement testing.
CAUTION: The tape may permanently adhere to some surfaces. The surface may be
damaged if the tape is removed.
The GLS-LOL can be mounted so that the cable enters through the photocell base and is
not visible (flush mount) or so that the cable exits the side of the lens assembly and runs
along the exterior of the ceiling or
wall (surface mount). Refer to the figures in the right
column as necessary during mounting procedures.
1. Remove the base from the lens assembly.
2. Open a wire entry location in either the Base or the Lens Assembly.
A. Flush Mount (wire entry through base). Use this mounting procedure when
the wires will be concealed within the wall or ceiling.
1) Put the base on a sturdy, flat surface so that the inside of the base is
on the flat surface and the outside of the base is facing you. Locate
the horseshoe shaped area in the center of the base.
2) Apply firm pressure to the center of the horseshoe with a punch tool
and tap with a hammer to knockout the wire entry.
3) Thread the cable
from the controller through the outside of the base
toward the inside.

B. Surface Mount (wire entry through lens assembly). Use this procedure
when the wires will run on the surface of the wall or ceiling.
1) Locate the wire entry location in the opaque white plastic cover at
the opposite side from the translucent lens opening.
2) Use needle-nose pliers or wire cutters to break away the white plastic
covering of the wire entry.
3. Connect the wires to the terminals on the lens assembly as shown in the
connection diagrams.
4. Return the base to the lens assembly.
A. Align the arrow and sun icon inside the base with the lens opening.
B. Use gentle pressure to snap the parts together.
5. Remove the opaque white cover from the photocell. Insert a thin screwdriver
blade between the white cover and the lens opening, then pop off the white
cover.
6. Secure the photocell with screws
(not provided). Use two #4 screws of the
appropriate length. For ceiling tiles, use machine screws with appropriate
washers and nuts. Use wood or masonry screws for solid surfaces. The “Field
of View & Mounting” figure on the first page shows flush mounting to a ceiling
tile or drywall using machine screws, washers and wing nuts.
Insert screws through the mounting holes as shown in the last figure in the next
column. Make sure the placement and orientation is the same as it was during
testing. Tighten the screws and fastening hardware.
7. Snap the white cover in place over the lens assembly.

TROUBLESHOOTING
Refer to the wiring diagrams
in the right column.
Improper sensor location.
Verify that sensor is located
such that it can detect the
desired workspace light
levels.
Incorrect wiring between
sensor and GLS-SIM (or
other compatible interface.
Improper control system
programming
Check logic in control
processor or contact Crestron
for assistance.
Lights don’t respond to
change in ambient light
level.
