NOTE: DO NOT FORCE 270-DEGREE POTENTIOMETERS

BEYOND THEIR NORMAL RANGE OF MOTION

OR DAMAGE MAY RESULT!

Auto Close Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to close automatically,

provided no open, reversing or obstruction signals are present from the fully-open position. This timer is adjustable from 0 to 124

seconds. This feature is turned on or off using dip switch #1.

Maximum Run Timer Adjustment: This 270-degree adjustable potentiometer sets the amount of full speed run time for the

operator, as well as the maximum run time. There should be approximately three seconds of slow speed travel before reaching

the end of travel. Maximum run is set automatically as 10 seconds longer than the length of time at full speed.

Open Direction Current Sense Adjustment: This multi-turn potentiometer is used to calibrate the built-in current sensing

feature for detection of obstructions while running in the open direction.

Close Direction Current Sense Adjustment: This multi-turn potentiometer is used to calibrate the built in current sensing

feature for detection of obstructions while running in the closed direction.

Dip Switches:

This switch turns the auto close timer off/on.

This switch is used in conjunction with alarms and flashing lights that may be added to the operator. When the switch is

in the ON position, these devices will start approximately two seconds prior to the operator starting. In the OFF position,

the devices will only work while the operator is running.

This switch is used in conjunction with single-button controls and radio receivers. In the ON position, successive inputs

will cause signals in the order of OPEN-STOP-CLOSE-STOP. In the OFF position, inputs will cause an OPEN signal

unless the gate is fully open, in which case it will signal CLOSE.

Not used at this time.

When turned ON, this switch will allow a one-second delay for solenoid locks to unlock before the motor starts.

When turned ON, this switch disables the soft start/stop feature. If the switch is in the OFF position and the soft start/stop

isn't noticeable, remove one of the two R2 resistors.

Not used at this time.

Not used at this time. Set to OFF.
