EXPANSION BOARD AUXILIARY RELAYS AUX RELAY 1 Normally - open and normally - closed relay contacts to control external devices, function of relay contact activation determined by AUX Relay 1 option switch settings. (For connection of Class 2, low voltage (42 Vdc [34 Vac] max 5 Amps, power sources only.) AUX RELAY 2 Normally-open and normally-closed relay contacts to control external devices, function of relay contact activation determined by AUX Relay 2 option switch settings. (For connection of Class 2, low voltage (42 Vdc [34 Vac] max 5 Amps, power sources only.) AUX RELAY SETTING SWITCH SETTINGS AUX RELAY 1 AUX RELAY 2 123 Off (no feature OFF OFF OFF selected) Relay always off. Use this Aux Relay setting to conserve battery power. Open Limit Switch OFF OFF ON Energizes at open limit. Use with SAMS (Sequenced Access Management System, jointly with barrier gate). Close Limit Switch OFF ON OFF Energizes when not at close limit. For an additional audible or visual display, connect an external light (low voltage). Gate Motion OFF ON ON Energizes when motor is on (gate in motion). For an additional audible or visual display, connect an external buzzer or light (low voltage). Pre-Motion Delay ON OFF OFF Energizes 3 seconds before gate motion and remains energized during Energizes 3 seconds before gate motion and remains gate motion. The onboard alarm will sound. For an additional audible energized during gate motion. For an additional audible or or visual display, connect an external buzzer or light (low voltage). visual display, connect an external buzzer or light (low voltage). Power ON ON OFF Energizes when AC power or solar power is present. There is approximately a 10-12 second delay before relay cutoff, after AC shutdown. Energizes when on battery power. There is approximately a 10-12 second delay before relay cutoff, after AC shutdown. Tamper ON OFF ON Energizes if gate is manually tampered with by being pushed off of Energizes if gate is manually tampered with by being pushed close limit. For an additional audible or visual display, connect an off of close limit. For an additional audible or visual display, external buzzer or light (low voltage). connect an external buzzer or light (low voltage). Cycle Quantity ON ON ON The 1, 2, and 3 LEDs will blink out the cycle count (cycle count is Feedback* stored on the control board). See below. Not used. 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.
