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)
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.
