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, or from 3 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
object 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 reversing). The factory setting is MIN.

WARNING!
All three potentiometers were set to minimum at the factory. The OBSTRUCT SENS.
potentiometer MUST be adjusted above the factory setting for your SL-2000B 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.
