EXPANSION BOARD OVERVIEW
ADDITIONAL FEATURES
To AVOID damaging the circuit board, relays or accessories, DO NOT connect
more than 42 Vdc (32 Vac) to the AUX relay contact terminal blocks.
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 OPEN, CLOSE, and STOP LEDs will blink out the cycle count, with OPEN LED blinking 1000’s, CLOSE LED blink 10,000’s, STOP LED blinking 100,000’s, and
simultaneously all three LED’s blink 1,000,000’s (e.g. Open blinks 3 times, Close blinks 6 times, and Stop 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 Open, Close, and Stop 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.

Off (no feature selected) OFF OFF OFF 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
gate motion. The onboard alarm will sound. For an additional audible or
visual display, connect an external buzzer or light (low voltage).
Energizes 3 seconds before gate motion and remains energized
during gate motion. For an additional audible or 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 close
limit. For an additional audible or visual display, connect an external
buzzer or light (low voltage).
Energizes if gate is manually tampered with by being pushed

EXPANSION BOARD OVERVIEW
1 QUICK CLOSE Switch:
OFF: No change to the gate's normal operation.
ON: When CLOSE EYES/Interrupt loop is deactivated it causes an opening or a stopped
gate to close (ignores the Timer-to-Close).
2 AC FAIL OPEN/BATT Switch:
OPEN: Loss of AC power will cause the gate to open approximately 15 seconds after AC
power fail and remain OPEN until AC power is restored (enabling the Timer-to-Close).
BATT: With loss of AC power, gate will remain in present position and operator is
powered from batteries.
3 LOW BATT/EXIT LOOP FAIL Switch:
• When AC power is OFF and battery voltage is low the gate will latch at a limit until
AC power is restored or batteries voltage increases.
• Option select switch set to OPEN forces gate to latch at the OPEN limit if it is at the
OPEN limit or on next open command until AC power is restored or battery voltage
increases.
• Option select switch set to CLOSE forces gate to latch at CLOSE limit if at CLOSE limit
or on next CLOSE command until AC power restored or battery voltage increases.
• Constant pressure on a hard command input overrides to open or close the gate.
• Low battery detect point = 22 V
• When set to OPEN, if the EXIT plug-in loop detector detects a fault, then the gate will
open and remain open until fault is cleared. When set to CLOSE, then plug-in EXIT
loop detector faults are ignored (EXIT loop is faulted and inoperative).
4 ANTI-TAIL OPEN/CLOSE SELECTION switch:
OFF: When CLOSE EYES/Interrupt loop is activated it causes a closing gate to stop and
reverse.
ON: When CLOSE EYES/Interrupt loop is activated it causes a closing gate to pause. Once
the vehicle is clear the gate will continue to close.
5 AUX RELAY switches: Set the AUX RELAY switches as needed to obtain the desired
function as shown in the table below.

6 Firmware Version: To check the firmware version for the expansion board:
1. Locate the OPEN, CLOSE, STOP, and DATA LEDs on the expansion board.
2. Disconnect AC/DC power to the main control board for 15 seconds.
3. Connect power. The OPEN, CLOSE, and STOP LEDs will flash in sequence until
the main control board firmware revision is displayed. When the green DATA
LED glows solid the OPEN LED will flash the version number, then stop, then
the CLOSE LED will flash the revision number (for example: For version 5.1
when the green DATA LED is solid the OPEN LED will flash 5 times, then stop,
then the CLOSE LED will flash once).
