RS-500 5K Walk-In Cooler Door Installation and Operation Manual
Section 3.4: Infrared Safety Beam
The infrared emitter installed near the bottom of the door produces a constant, invisible beam that is ordinarily intercepted by
the receiver. If this beam is interrupted (
e.g.
by a person or a forklift) while the door is closing, the door will stop and reverse to the
fully open position.
