Safe guard (Infrared device or Photocell)
It is recommended that the installer purchase and install infrared photocells for additional
safety. Photocells work by inhibiting the movement of the gate if the beam is broken. Infrared
safety devices may be required by law in some areas. If the infrared beam is broken during
closing, the gates will reverse and open immediately. During opening, the beeper will ring.
Infrared photocells come in active and passive varieties. Active photocells require power on
both sides of the driveway, passive photocells employ a reflector plate so that power is only
required on one side of the driveway. Most photocells will provide DC power input wires +
and -, and normally closed switch wires. To install the photocell, attach the DC power + wire
to terminal 12 on jack JX3, and the common, ground or – DC wire to 0 on jack JX3. Attach
the normally closed wire to IR and the common normally closed wire to 0. In most cases
these signal wires are not polarized so they can be interchanged without issue. Consult your
manufacturer’s documentation for details. See Figure 4 for a diagram of external interface
connections. The infrared device can be obtained through your dealer. To find a dealer, go

Maintenance
Every six months check the following items for proper operation of the unit:
l
Check the chain lubricant and add 1# grease regularly.
l
Lubricate shafts and sprockets.
l
Keep opener clean at all times. Check inside cover for insects.
l
Check and tighten anchors bolts.
l
The operator can be powered by battery in case of power failure. It still can provide
enough power for operating 10 cycles after power disruption. Operating should be less
than 20 cycles a day. Please switch off the battery if no power is available for more than
5 days (remove the plastic cover, Turn the switch on top of the operator to the off
position). Failure to comply with the above instructions may damage the battery or
shorten its life.
l
We recommend you put some grease in the keyhole to avoid rusting, also regularly
grease the wheels and axles if the gate was jammed or cannot be moved smoothly.
Occasionally inspect the chain to ensure that it is well lubricated, and oil the chain as
necessary.
