Expansion Board Overview

1. QUICK CLOSE switch:
OFF: No change to the gate/door'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/door 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/door will remain in present
position and operator is powered from batteries.
3. EXIT FAIL switch:
When set to OPEN, if the EXIT plug-in loop detector (Model
LOOPDETLM) detects a fault, then the gate/door 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/door to stop and reverse.
ON: When CLOSE EYES/Interrupt loop is activated it causes a closing
gate/door to pause. Once the vehicle is clear the gate/door 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)
11. Wireless edge input:
Input for the Wireless Edge Kit (Model LMWEKITU)
