WIRE AND MOUNT THE TRANSMITTER(S)
For best results, install with a clear line of sight between transmitter and operator.
1. Route the wires from the edge sensor into the transmitter. Connect the wires to either
terminal block (polarity is NOT important). The operator will beep once to indicate the
edge sensor has been learned. Apply pressure to edge. The red LED will flash if the
transmitter is wired correctly. Tighten the Heyco connector with 25 in. lbs. of torque
to make transmitter watertight. Use double hole Heyco connector when connecting 2
edge sensors (for gate operations only).
2. Attach the mounting bracket to the door with the screws provided (8-32 3/8" or 10-16
3/4") at least 3.28 ft. (1 m) above the ground. If installing on a round surface, use zip
ties (not provided).
3. Attach the transmitter housing with the screws provided.
4. Place the transmitter onto the mounting bracket and secure with the
1/4" screw provided.
TEST
Apply pressure to edge. The red LED on the TRANSMITTER will flash. The controller
LCD should state WLESS BLOCKED. If the TRANSMITTER LED does not flash, check
the transmitter for proper installation and wiring. See the Transmitter and Receiver
Troubleshooting page and check the edge sensor for proper installation and wiring.
Battery is fine.
Battery is low; the operator will beep twice.
Battery is critically low; the operator will not function until the battery is
replaced. The operator will either open automatically (fail-safe) or latch
at close (fail-secure) based on the operator setting (see the operator's
manual for more information).
