Photo Eye 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 align the system, especially with retro-
reective photoelectric sensors. To that end, HySecurity has provided a unique feature that turns power on to the
photo eyes and causes a buzzer to chirp when the photo eye enters and exits alignment. Align the photo eyes
using this feature by taking the following steps:
1. Move the gate off (away from) the close limit.
2. Access the User Menu and select PE. Refer to User Menu: Table 1 on page 39.
3. Set the menu item PE 0 to PE 1.
4. More the photo eyes to align the emitter beam. The buzzer will chirp twice when the beam is broken and
once when remade.
5. When the buzzer chirps once, indicating the photo eyes are aligned, close the gate. When the close limit
is triggered, the menu item PE resets to 0.
Monitored Connection
A monitored connection tests for the presence and correct operation of the photo eye prior to each gate
activation and prevents gate operation if any fault is present. The Installer Menu item PC 0 must be changed to
PC 1 to enable this feature.
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. An optional setting in the Installer Menu will cause a 2 second reversal of travel. Refer
to EC and EO in Installer Menu: Table 2 on page 42.
