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. 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. Obtain the COM from the STC Power Supply Board.
4. Connect the N.C. output to SENSOR 1, 2, or 3.
5. Congure the Installer Menu according to your site sensor set up. Refer to Table 4: Installer Menu
Settings for SENSOR Inputs on page 42.
NOTE: Jumper between terminals on Photo Eye sensor so you don’t need to pull a fourth wire to the Controller terminal. For
examples of wiring diagrams, refer to Wiring HySecurity Sensors: Smart Touch on page 131. To test Photo Eyes, see Supply Power to
the Sensors on page 43.
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 ve seconds. Optional settings exist in the Installer Menu. Refer to Eye Close Logic
and Eye Open Logic (EC and EO) in Table 6: Installer Menu on page 59 for more information.
Alignment:
Most photo eyes require careful optical alignment in order to aim the emitter beam to the center of the
receiver or reector. In order to avoid false triggering, it is important to carefully alignthe system, especially
with retroreective photo eyes. The best way to assure true centering of the beam is with some trial testing
where the emitter is shifted to move the beam left and right and up and down until the range of the invisible
cone of the infrared beam is known. Photo eyes usually provide alignment aid LED’s for this setup, but they can
be hard to see. HySecurity has provided a unique feature that turns power on to the photo eyes and causes
the buzzer to chirp when the photo eyes enter and exit alignment. See “Table X. Smart DC Controller - User
Menu Functions” on page XX to enable this feature. Set the menu item PE - PHOTO EYE ALIGN from a 0 to
a 1. The buzzer chirps once when the emitter and photo eye receiver are not aligned. When the emitter and
receiver are aligned, the buzzer chirps twice. If they go out of alignment again, the buzzer will chirp once. This
“alignment mode” will automatically reset to 0 the next time the Close Limit Switch is triggered or the RESET
key is pressed.
