Use Table C (below) as a guide. 3. Use XLP (cross-linked-polyethylene) type of wire. This wire reduces the effects of moisture and other environmental events in altering the functionality of the vehicular loop detector. 4. Twist the lead wire at least 6 turns per foot. 5. Use BACKER-ROD to minimize damage to the loop detector wire prior to using the sealant. 6. Place the loop detector wire and adjust the sensitivity of the vehicular loop detector unit in a way to minimize the effects of the gate over the loop detector wire. IMPORTANT – Some of the following parameters may affect the proper functionality of the vehicular loop detector (consult the installation manual and the manufacturer of the vehicular loop detector). • Gate size, • Number of turns in the loop sensor wire; • Distance from the loop sensor wire to the gate either at the open or close position.

The SECONDARY ENTRAPMENT PROTECTION like the edge sensor and the photoelectric beam MUST BE PART OF EVERY SINGLE INSTALLATION to prevent pedestrian or animal entrapment (see pages 6 and 7). The edge sensor and/or the photoelectric beam must be UL325 compliant devices.

The maximum voltage that the control board provides for external accessories is the maximum voltage of the battery, which is about 28 volts. In the event of an electrical short the board will protect itself by shutting down and will remain shut down until the short is corrected.

By having the radio receiver connected as illustrated and with the Hold Open Timer OFF (see below): Every command of the radio transmitter will control the gate as follow: a) First command opens the gate, b) Second command stops the gate and c) Third command closes the gate d) Any subsequent commands will continue in the same order to control the gate. This type of configuration is not recommended for a commercial installations. Open Only 2. By having the radio receiver connected as illustrated and with the Hold Open Timer ON (see below): Each command of the radio transmitter is ALWAYS AN OPEN COMMAND to the gate.

Set the Timer to the desired time, from 1 to 60 seconds. If this feature is not needed, turn the Trim Pot clockwise to the “off” position. Note: The Hold Open Timer affects the “radio receiver command” and the sequence of operation for the gate (see page 23).
