Potentiometers

The three (3) potentiometers on the control board operate like a volume control on a radio. They control the auto close timer, inertia, and obstruction sensitivity of the operator. Use a small slotted screwdriver to turn the arrow in the center of the potentiometer. Clockwise rotation increases the setting (MAX). Counterclockwise rotation decreases the setting (MIN).

INERTIA

AUTO CLOSE (auto close timer): Determines how long the gate will remain open before it automatically closes. The limits are OFF to 120 seconds. The factory setting is OFF.

INERTIA: Fine tunes obstruction sensitivity in the opening and closing modes. INERTIA allows the opener to attempt to push an obstruction clear of the gate path. When INERTIA is set to MIN the opener will obstruct quickly (i.e., will attempt to push an obstruction briefly); when set to MAX, the opener will obstruct

slowly (i.e., will push against an obstruction for a longer period). The factory setting is MIN.

OBSTRUCT SENS. (obstruction sensitivity): Determines the amount of force exerted by the gate on an obstruction before the operator stops and reverses. The gate will exert minimum force before obstructing when set to MIN. When set to MAX, the opera-

tor will exert maximum gate force before obstructing (i.e., the operator will require greater resistance before stopping and revers- ing.). The factory setting is MIN.

READ WARNING BELOW!

NOTE: Heavy gates and gates with high wind resistance may require the OBSTRUCT SENS. potentiometer to be set closer to MAX to prevent the operator from obstructing. Keep in mind, however, that while you must determine the best setting for smooth gate operation, you must ALSO determine the lowest possible setting for safe gate operation.

ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST WHEN ADJUSTING OR

SERVICING YOUR AUTOMATIC GATE OPERATOR!

WARNING!

All three potentiometers were set to minimum at the factory. The OBSTRUCT SENS. potentiometer MUST be adjusted above the factory setting for your GTO/PRO 2000 series operator to function properly. If the potentiometer is left at MIN, your gate operator may "obstruct" (i.e., stop and reverse) as soon as it is activated.

BE SURE TO PROPERLY RETEST THE GATE OPERATOR AFTER MAKING ANY ADJUSTMENTS; FAILURE TO DO SO MAY RESULT IN SERIOUS INJURY OR DEATH.
