13.9. Safety Beams
• The CENTURION i5 or other four-wire Safety Beams may be connected to the RDO II (For two-wire beams, set
the jumper to 2W. For four-wire beams, set the jumper to 4W (Figure 19))
• The installation of Safety Beams greatly enhances safety by constantly monitoring for persons or objects which
may pass within the path of the moving garage door
• The RDO II will commence to Safety Reverse if the Safety Beams become momentarily or permanently
interrupted during a Close Cycle
Mounting
• Mark the inside garage door framing so that the bottom edge of the i5 beam sits 125mm off the floor
• Using a small angle bracket, fasten each beam to the wall so that they face each other across the garage door
Connection
• Follow Safety Beam instructions and connect to the Output Terminals. Use the normally-open contacts of the beam
to connect to input SB4 on the RDO (Figure 19A/B)
Important note: RDO II provides 24V DC output and normally-open input.
Alignment
• Adjust the Safety Beam module marked “Transmitter” (by turning the mounting bracket) so that it is aimed
directly at the lens of the Safety Beam module marked “Receiver”. A GREEN indicator lamp located on the
“Receiver” will glow once the correct alignment has been achieved
• Test the Safety Beam alignment several times, each time ensuring that when the Safety Beams are obstructed
the green indicator lamp extinguishes and when unobstructed the indicator lamp glows solid
• Firmly tighten the Safety Beam mounting bracket fixing screws
• Installation of the Safety Beams is now complete
Enabling
• Remove the Courtesy Lamp and Control Box Covers to expose the Control Board
• Select Dip 2 (SB) to the “ON” position (Figure.20)
• Replace the Control Box and Courtesy Lamp Cover
