OPERATION NOTES
• A thru-beam sensor is generally more powerful and able to function reliably with dirty optics and in
poor weather.
• A retro-reflective sensor does not require the installation and extra wiring of a separate emitter and
receiver as is required in a thru-beam system, but retro-reflective eyes are generally more problematic
in poor weather. Avoid using retro-reflective devices across outdoor distances greater than 24 feet
(7.3m) because of performance and reliability issues.
Mount thru-beam type photo eyes approximately 15” to 30” (.38m to .76m) above the ground and as
close to the gate as possible. A minimum of two photo eyes are required, one photo eye to guard the
open direction and the other for the close direction of travel, unless gate edges for entrapment protection
are installed. Mount the emitters and the receivers just beyond the travel of the gate in both the full open
and full closed positions of travel. The installation locations described above are intended for pedestrian
detection. If photo eyes are to be used for vehicular detection, install a low elevation photo eye for cars
and another photo eye at a height of about 55” (140cm) to detect semi-trucks.
Figure 43. Connections for Entrapment
Protection Only
If the photo eye has an internal switch for
setting Light Operate vs. Dark Operate, select
Light Operate. If the photo eye has a relay
output and has both NO and NC terminals, some
experimentation may be required to determine
the proper connection. This is because, in the
Light Operate mode, the output relay is normally
energized and releases when the beam is blocked.
Some manufacturers label an output as NO, when
it is actually an NC contact. If the photo eye has a
solid-state output you must choose a sinking type
connection.
Three wires to the receiver and two wires to the
emitter are all that is required.
• Depending on how the photo eyes are to be
wired, +24VDC or +12VDC, power is provided
via spades located just to the right of the COM
terminal strip near the left side of the board.
Wire all eyes to 24V or all to 12V; do not mix
voltages.
• The receiver common wire is connected to the
SENSOR COM terminal at the bottom left of
the SmartDC Controller. The emitter common
wire is connected to the COM terminal at the
top left of the controller.
• The photo eye NC output wires connect to the
SmartDC Controller at the appropriate Sensor
Input (1, 2, or 3).
If photo eyes are to be used for
vehicle detection and logically
function the same as a vehicle
detector, connect the common wires
to the COM terminals on the left
side of the board and wire the NO
output contact to the appropriate
vehicle detector input: EXIT LOOP,
IN OBS LOOP, and OUT OBS LOOP.
