EXPANSION BOARD OVERVIEW l 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. EXIT FAIL Switch 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. CLOSE: If the EXIT plug-in loop detector (model LOOPDETLM) detects a fault, faults are ignored (EXIT loop is faulted and inoperative). AC FAIL Switch NOT USED 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. 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). 30

AC FAIL Switch
NOT USED
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.
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).
