US Automatic PHOTO EYE User manual

1. INSTALLATION
NOTE: Mounting brackets should be installed to a rigid object to
prevent movement which could affect alignment and cause failures.
IMPORTANT: Conduit should be used from the control box to the
photo eye wiring box to protect wires from damage and moisture.
The wiring box has ½ inch knockouts located on the back and
bottom for the conduit connection. Do not remove the
TX-Transmitter wiring box knockout if using battery option.
1. Determine the best location for the photo eyes considering the
correct distance from the ground, conduit for wiring, location
of any irrigation system that might exist (avoid water spray) and
mounting surfaces are aligned with one another.
2. Install the mounting brackets and verify they are aligned with
each other. See figure 1.
3. Install the Transmitter and Receiver wiring box to the mounting
brackets using 4 screws and nuts.
4. Install the conduit to the receiver wiring box. If hardwired
installation install conduit for transmitter wiring box.
5. Install the receiver wires into the wiring box. If hardwired
installation install transmitter wires into the wiring box.
6. Route wire through the photo eye back plate.
7. Install the Transmitter and Receiver photo eye back plate to the
wiring box using the 4 sheet metal screws.
8. Connect wires per the wiring instructions.
9. Do not install covers at this time, this will be done after alignment
is complete.

Read all instructions before installing this product.
Monitoring Method: N/C Contact
The infrared photo eyes are a People and Property safety device
intended for use with automatic gate operating systems. Swing gate
operators require at least one external monitored entrapment device
for gate operation and Slide gate operators require at least two
external monitored entrapment devices (one for each direction) for
gate operation per UL325 the standard for gate operator safety.
See gate operator installation manual.
The transmitter can be powered by two 3.6 vdc lithium batteries
(model - ER14505) or it may be hard-wired to the gate operator
control board. The expected battery life should exceed 1 year.
Rated range up to 42 feet / 13 meters in most conditions.

3. ALIGNMENT
The RX / Receiver has a red LED which will illuminate when
power is applied to the RX / Receiver. When aligned with the
TX / Transmitter, the red LED will go OFF and the green LED
will come ON. When beam is broken, the red LED will come
ON and the green LED will go OFF.
A feature to assist in the
optimal alignment allows
for a voltmeter to be
connected to the TP- and
TP+ test points located on
the RX / Receiver. With
voltmeter attached use
alignment chart verify the
optimal alignment.
Alignment Chart
TP-/TP+ readings
DCV Signal Strength Red LED Grn LED
0 Vdc No Signal ON OFF
3 Vdc Minimum useful signal OFF ON
5 Vdc Maximum useful signal OFF ON
Once alignment is complete, install the covers using the 4 black
screws. Install the hood onto each unit.
4. BATTERY INFORMATION
TX / Transmitter battery Requirement - Two 3.6 vdc lithium
batteries (model - ER14505) or equivalent. When installing
