Connecting Infrared Photocells
The below steps must be completed by licensed electrician.
Highly recommend the use of infrared photocells as an additional safety feature.
While closing, if the ray of the Infrared Photocell is blocked, the gate will stop and open
immediately, to protect user and property security. To install photocells, connect wiring as
per Figure 21. You must remove the wire jumper between terminal IR and terminal GND on
X5 (ref to Figure 22).
The distance between photocell receiver and photocell transmitter should not be less than 2
meters; otherwise, the induction effect of photocell may be affected.
