Photo Eye Installation
MX3650-01 Rev. D
55
Configuration
Configure photo eyes attached to gate operators manufactured in 2016 or beyond according to
UL 325 –
Monitored Entrapment Wiring Diagrams
.
NOTE:
HySecurity gate operators, manufactured with 2016 (or later) in the serial number, require Normally Closed output sensors.
Some manufacturers label an output as N.O. (normally open), when it is actually an N.C. (normally closed) contact. Review
External
Entrapment Protection Sensors monitored by HySecurity Gate Operators on page 9
.
If your gate operator is manufactured prior to 2016 and/or your gate operator is set to Build
Year 1, consider the following:
NOTE:
To check the Build Year for your gate operator, press the Menu button. The gate status scroll reveals
the Build Year. “Build Year Pre-2016” means the gate operator is configured for Build Year 1.
1. If the photo eye has an internal switch for setting Light Operate versus Dark
Operate, select Light Operate.
2. If the photo eye has a relay output and has both N.O. and N.C. terminals, some
experimentation may be required to determine the proper connection because,
when its in the Light Operate mode, the output relay is normally energized and
releases when the beam is blocked.
3. If the photo eye has a solid-state output, your must choose a sinking-type connection.
Photo Eye Connections: Smart Touch & Smart DC Controllers
CAUTION
All external entrapment protection sensors must be NC sensor outputs and wired to the SENSOR COM terminal for
monitoring and powering purposes. The sensor becomes actively powered when the gate operator’s motor runs.
Connect the four wires to the receiver and two wires to the emitter according to the following procedure.
A. Supply power to the sensor.
1. Find the +24V spade-terminals inside the inputs edge or use +24V from RADIO OPTIONS located at
the base of the SDC Controller. (If connecting to STC, obtain the +24 Volt source power at one of the
three spade-terminals on the STC Power Supply Board. )
2. Obtain the 24 Volt Common from SENSOR COM on the Controller.
B. Wire connection so the controller recognizes the sensor device.
3. For the relay output, obtain the COM along the SDC inputs edge (or from the STC Power Supply Board
on an STC).
4. Connect the N.C. output to SENSOR 1, 2, or 3.
5.
Configure the Installer Menu according to your site device set up. Refer to
UL 325 – 2016, Monitored
Entrapment Wiring Diagrams.
NOTE:
Jumper between terminals on Photo Eye sensor so you don’t need to pull a fourth wire to the Controller terminal
.
Photo Eye Function
If the gate is stationary, a tripped photo eye will prevent the gate from starting in either direction. If tripped
while in motion, the standard function is to pause the gate motion and then automatically restart again if the
photo eye is clear within five seconds. Optional settings exist in the Installer Menu. Refer to Eye Close Logic
and Eye Open Logic (EC and EO) in
Table 4: Installer Menu on page 25
for more information.
