EXPANSION BOARD 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. 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 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 EXIT LOOP FAIL Switch: When set to OPEN, if the EXIT plug-in loop detector (Model LOOPDETLM) 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 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 on the following page. 6 EYE/EDGE Switches: Set the EYE/EDGE switches as needed to obtain the desired OPEN or CLOSE functionality. 7 1, 2, and 3 LEDs: LEDs indicating the status of the EYE/EDGE inputs. Also used to check the firmware version of the expansion board: 1. Locate the 1, 2, and 3 LEDs on the expansion board. 2. Disconnect AC/DC power to the main control board for 15 seconds. 3. Connect power. The 1, 2, and 3 LEDs will flash in sequence until the main control board firmware revision is displayed. When the green POWER LED glows solid the LED 1 will flash the version number, then stop, then the LED 2 will flash the revision number (for example: For version 5.1 when the green POWER LED is solid the LED 1 will flash 5 times, then stop, then the LED 2 will flash once). 8 MAIN BOARD Input: Input Connection for the main board connector. 9 Input LEDs: LEDs indicating the status of the SBC, OPN, CLS, and STP inputs. 10 Loop Detector Inputs: Inputs for the Plug-In Loop Detectors (Model LOOPDETLM) 10 5 SHADOW INTERUPT EXIT 1 23 4 31 OPEN CLOSE POWER TO MAIN BOARD 8 6 7 1 EYE ONLY 2 EYE/ EDGE 3 EYE/ EDGE COM 9 SBC OPN CLS STP COM

EXIT LOOP FAIL Switch:
When set to OPEN, if the EXIT plug-in loop detector (Model
LOOPDETLM) 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).

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.

AUX RELAY Switches:

1, 2, and 3 LEDs:
LEDs indicating the status of the EYE/EDGE inputs.
Also used to check the firmware version of the expansion board:
1.
Locate the 1, 2, and 3 LEDs on the expansion board.
2.
Disconnect AC/DC power to the main control board for 15
seconds.
3.
Connect power. The 1, 2, and 3 LEDs will flash in sequence until
the main control board firmware revision is displayed. When the
green POWER LED glows solid the LED 1 will flash the version
number, then stop, then the LED 2 will flash the revision number
(for example: For version 5.1 when the green POWER LED is solid
the LED 1 will flash 5 times, then stop, then the LED 2 will flash
once).

MAIN BOARD Input:
Input Connection for the main board connector.
9
Input LEDs:
LEDs indicating the status of the SBC, OPN, CLS, and STP
inputs.
10
Loop Detector Inputs:
Inputs for the Plug-In Loop Detectors (Model
LOOPDETLM)
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.
