CYCLE COUNT
* First, note the current Aux Relay switch positions. To
determine the actual cycles that the gate operator has
run (in thousands), set all three Aux Relay switches to
the ON setting for Aux Relay 1. The Expansion Board's
OPEN, CLOSE, and STOP LEDs will blink out the cycle
count, with OPEN LED blinking 1000's, CLOSE LED blink
10,000's, STOP LED blinking 100,000's, and
simultaneously all three LED's blink 1,000,000's (e.g.
Open blinks 3 times, Close blinks 6 times, and Stop
blinks once. Cycle count is 163,000.). Cycle count
displayed is between 1,000 and 9,999,000 cycles.
After servicing, set Aux Relay switches back to their
appropriate positions. Cycle count cannot be reset or
changed. If under 1,000 cycles the Open, Close, and
Stop LEDs will turn on for 10 seconds, then turn off.
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).
OPEN: Loss of AC power will cause gate to immediately OPEN 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.
• When AC power is OFF and battery voltage is low the gate will latch at a limit until AC power is restored or batteries voltage increases.
• Option select switch set to OPEN forces gate to latch at the OPEN limit if it is at the OPEN limit or on next open command until AC power is
restored or battery voltage increases.
• Option select switch set to CLOSE forces gate to latch at CLOSE limit if at CLOSE limit or on next CLOSE command until AC power restored or
battery voltage increases.
• Constant pressure on a hard command input overrides to open or close the gate.
• Low battery detect point = 22 V
• When set to OPEN, if the EXIT plug-in loop detector 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).
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.
Set the AUX RELAY switches as needed to obtain the desired function:
AUX RELAY 1
Relay always off. Use this Aux Relay setting to conserve
battery power.
Energizes at open limit. Use with SAMS (Sequenced Access Management
System, jointly with barrier gate)
Energizes when not at close limit. Connect "Gate Close/Secure" indicator
(e.g. light).
Energizes when motor is on (gate in motion). Connect "Gate In Motion"
indicator (e.g. warning light or sounder).

a 10-12 second delay before relay cutoff, after AC shutdown.
Energizes if gate is manually tampered with by being pushed off of close
limit. Connect alert (e.g. light or sounder).
The OPEN, CLOSE, and STOP LEDs will blink out the cycle count.
