SYSTEM OPERATION REFERENCE

CONTROLS, INDICATORS, INPUTS AND ADJUSTMENTS

For control and indicator locations, refer to Figure 11. For detailed explanations of the Gate Operator's various, controls, indicators, inputs and adjustments, refer to the following pages.

CONTROLS

KEYPAD	The 12-key keypad is used for local operation, programming and
	service.
SWITCH S2
GATE OPEN TO	Selects the direction the gate will open (LEFT/RIGHT).
LEFT/RIGHT
SWITCH S3
LOW BATTERY	Selects the direction the gate will move and remain when the LOW
LEFT/RIGHT	BATTERY input is activated by an Uninterruptible Power Supply (UPS).

INDICATORS

LED indicators light when controls and inputs are active. Additional indicators are as follows:

DISPLAY	This is a seven segment character display that gives numerical
	response to service personnel during programming and operation.
LEFT LIMIT	Indicates that the LEFT limit switch is activated.
RIGHT LIMIT	Indicates that the RIGHT limit switch is activated.
MTR LEFT	Indicates the gate is moving to the left.
MTR RIGHT	Indicates the gate is moving to the right.
RECV	Indicates data is being received from the other unit in a Master/
	Slave system.
XMIT	Indicates data is being sent to the other unit in a Master/Slave
	system.
OFF HOOK	Indicates the gate operator is off hook and using the phone line.
OBSTRUCTION	Indicates the peak or average motor current threshold was reached
	and the motor was stopped. See Fault List.
INTERRUPT BAR	Indicates Interrupt Bar (Edge Sensor) switch was activated
(EDGE SENSOR)	and the motor was stopped.
OPEN MTR	Indicates the motor is engaged, but is not drawing any current. The
	thermal overload switch on the motor may need to be reset. See
	Fault List.
STUCK LIMIT	Indicates that a limit switch is stuck closed.
MAX RUN TIME	Indicates the motor ran for 75 seconds without reaching a limit switch
