GTO SL-2000B, SL-1000B installation manual Potentiometers

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).

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 operator to attempt to push an obstruction clear of the gate path. When INERTIA is set to MIN the operator will obstruct quickly (i.e, will attempt to push an obstruction briefly); when set to MAX the operator will obstruct slowly (i.e., will push against an obstruct 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 operator 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 OB- STRUCT SENS. potentiometer to be set closer to MAX to prevent the opera- tor from obstructing. Keep in mind, however, that while you must determine the best setting for smooth gate operation, you must ALSO determine the low- est 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 SL-1000 or SL-2000 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.
