EXPANSION AND RELAY ADAPTER BOARDS Auxiliary Relays The expansion board and relay adapter board provide Normally Open (N.O.) and Normally Closed (N.C.) relay contacts to control external devices, for connection of Class 2, low voltage (42 Vdc [34 Vac] max 5 Amps) power sources only. Function of relay contact activation determined by switch settings.

Use this Aux Relay setting to conserve battery power. OFF OFF ON Energizes at open limit. Use with SAMS (Sequenced Access Management System, jointly with barrier gate). OFF ON OFF Energizes when not at close limit. For an additional audible or visual display, connect an external light (low voltage). Energizes when motor is on (gate in motion). For an additional audible or visual display, connect an external buzzer or light (low OFF ON ON voltage).

ON OFF ON Energizes if gate is manually tampered with by being pushed off of close limit. For an additional audible or visual display, connect an external buzzer or light (low voltage). The 1, 2, and 3 LEDs will blink out the cycle count (cycle count is Red/green light functionality, see below. ON ON ON stored on the control board). See below. * Cycle count First, note the current Aux Relay switch positions. To determine the actual cycles that the gate operator has run (in thousands), set all three Aux Relay switches to the ON setting for Aux Relay 1. The Expansion Board's 1, 2, and 3 LEDs will blink out the cycle count, with 1 LED blinking 1000's, 2 LED blinking 10,000's, 3 LED blinking 100,000's, and simultaneously all three LED's blink 1,000,000's (e.g. 1 LED blinks 3 times, 2 LED blinks 6 times, and 3 LED blinks once. Cycle count is 163,000.). Cycle count displayed is between 1,000 and 9,999,000 cycles. After servicing, set Aux Relay switches back to their appropriate positions. Cycle count cannot be reset or changed. If under 1,000 cycles the 1, 2, and 3 LEDs will turn on for 10 seconds, then turn off. NOTE: The expansion board will flash the cycle count 3 times then all the LEDs will turn on solid for 10 seconds then turn off. RED/GREEN LIGHT FUNCTIONALITY Red light wired to AUX RELAY 1.
