1
QUICK CLOSE Switch:
OFF: No change to the door's normal operation.
ON:
When CLOSE EYES/Interrupt loop is deactivated it causes
an opening or a stopped door to close (ignores the Timer-to-
Close).
2
AC FAIL Switch:
OPEN: Loss of AC power will cause the 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, door will remain in present position
and operator is powered from batteries.
3
EXIT LOOP FAIL Switch:
OPEN: if the EXIT plug-in loop detector detects a fault, then
the door will open and remain open until fault is cleared.
CLOSE: The 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 door to stop and reverse.
ON: When CLOSE EYES/Interrupt loop is activated it causes a
closing door to pause. Once the vehicle is clear the door will
continue to close.
5
AUX RELAY Switches:
Set the AUX RELAY switches as need-
ed to obtain the desired function as shown on pages 20-21.
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
WARNING
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.
