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 (will
attempt to 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 reversing.). 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 1000 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.
