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 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.
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.
