EXIT) and the RELAY COMMON signal connected to Terminal #16 (COMMON) of the GS4000, See Figure 19. DO NOT CONNECT THE FREE EXIT OUTPUT SIGNAL TO ANY OTHER TERMINAL, SUCH AS RADIO OPEN, BECAUSE THE GATE WILL CLOSE AFTER REACHING THE OPEN LIMIT AND THE TIMER TO CLOSE HAS COMPLETED ITS CYCLE, EVEN THOUGH THE VEHICLE HAS NOT EXITED THE FREE OUT LOOP.

PRESETTING THE MOTOR OVERLOAD

SENSITIVITY POTENTIOMETERS

The GS4000 has independent adjustments for Open and Close Overload Sensitivity. The GS4000 is shipped from the Factory with the overload settings at their most sensitive setting. During the initial check out phase, it will be necessary to adjust the sensitivity to prevent inherent overloads from gate friction and other gate anomalies. See Figure 20. Adjust the OPEN and CLOSE OVERLOAD potentiometers approximately 1/4 turn clockwise.

Note! Turning the potentiometer clockwise decreases sensitivity. Turning the potentiometer counterclockwise increases sensitivity.

WARNING: THE OVERLOAD POTENTIOMETERS MUST BE SET MORE PRECISELY PRIOR TO COMPLETING THE GS4000 INSTALLATION. (See, FINAL SETTING OF THE MOTOR OVERLOAD SENSITIVITY)

CONNECTING THE LOOP WIRES

Follow the instructions of the Vehicle Detector Manufacturer when connecting the loop wires. Good, tight connections are most important. It is recommended that these wires be soldered to the wiring harness of the Vehicle Detector.

#	NAME	DESCRIPTION
1	24 VAC	Provides maximum 10 VA auxiliary
		power for accessories.
2	24 VAC	Provides maximum 10 VA auxiliary
		power for accessories.
3	ALTERNATE	Momentary input, must be released
		and re-entered to be recognized.
	This input is used for “COMMAND OPEN/COMMAND
	CLOSE” applications. The 1st signal will cause the gate
	to begin opening. A 2nd signal received during the open
	cycle will stop the gate immediately. A 3rd signal will
	close the gate. Connect appropriate access control
	devices to this terminal and #16 COMMON. Disable the
	Close Timer (rotate pot fully counter-clockwise).
4	RADIO OPEN	Momentary input, must be released
		and re-entered to be recognized.
	Once activated the gate will open fully. Activation while
	the gate is closing will cause it to re-open.
5	FREE EXIT	Momentary or continuous input.
	Once activated the gate will open fully. Activation while
	the gate is closing will cause it to re-open. Continuous
	activation while the gate is open will prevent the Timer-
	To-Close function from automatically closing the gate.
6	OPEN	Momentary or continuous signal. On/
		Off mode set by Switch #1
	WITH SWITCH 1 OFF: Once activated the gate will open
	fully. Activation while the gate is closing will cause it to
	re-open. Continuous activation while the gate is open
	will prevent the Timer-To-Close function from
	automatically closing the gate. Continuous signal
	required to move the gate when in the alarm mode.
	WITH SWITCH 1 ON: Gate does not respond to
	pushbutton input when in the normal mode. Continuous
	signal required to move the gate when in the alarm
	mode.
