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 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)
11.
Wireless edge input:
Input for the Wireless Edge Kit (Model LMWEKITU)
