Troubleshooting Guide
If your Wireless Vehicle Sensor is not operating properly, please follow this checklist:
IMPORTANT: If you make any of the following adjustments, you will need to recalibrate the
Transmitter Module before retesting (see page 3).
A. IF THE GATE IS NOT OPENING:
1. Check the batteries:
a. Verify batteries are installed correctly (align the “+” signs on the battery and in the battery compartment).
b. Verify batteries are working. Remove and reinstall the batteries. The Transmit Indicator on the Transmitter
Module should blink for 30 seconds. If not, try installing a new pair of “AA” batteries.
NOTE: When reinstalling batteries, the system will need to recalibrate (page 3). Do not move any metal
objects or the Transmitter Module for 60 seconds after reinstalling batteries.
2. Verify that the Sensor Cable is connected to the base of the Transmitter Module.
3. Increase the Sensitivity Adjustment on the Transmitter Module (page 3).
4. Verify that you have properly placed the Transmitter Module. Be sure it is installed:
• on the same side of the driveway as the gate opener/receiver.
• within 100 ft. and “line of sight” of the gate opener/receiver.
• 12 in. above ground level.
5. Verify that the Sensor is not more than 2 ft. from—and parallel to—the driveway edge.
6. If the RB709U-NB Receiver was installed:
a. Repeat the “learn” process (pages 4–5).
b. Verify that the Receiver is correctly wired to the gate opener control board (page 5):
c. Verify that the Receiver was mounted correctly (page 4):
• not mounted upside down.
• not mounted on a metal surface.
7. If the RB709U-NB Receiver was NOT installed:
a. Verify that the Transmitter Module DIP Switch settings were adjusted to match the Entry Transmitter’s DIP
Switch settings (page 1).
b. Verify that the Entry Transmitter opens the gate. If not, you will need to program the Entry Transmitter’s
settings into the gate opener receiver (see your gate opener Installation Manual), and then match the
Transmitter Module’s DIP Switch settings with the Entry Transmitter.
B. IF THE GATE IS OPENING “ON ITS OWN”:
1. Verify that the Sensor is at least 25 ft. from the roadway and/or neighbors’ driveways.
2. Verify that there are no moving metal objects within a 25 ft. radius of the Sensor. (NOTE: in areas with high
winds, metal objects such as flag poles/swing sets can trigger the Sensor if they are within range.)
3. Make sure Sensor Cable is not run in PVC conduit along with other AC or control wires.
4. Adjust the Sensitivity on the Transmitter Module (page 3).
