3.3 Limit Sensors Adjustment -
Select your specific operator
The limit sensors on the operator MUST be adjusted to control the travel of the gate and to precisely set the full open and full
closed position of the gate. Use ONLY the limit sensor instructions for your SPECIFIC operator type (6004, 6006 or 6400).
This feature is especially useful in applications where the gate opens partially, such as on a curved driveway.

Two thru-bolts 13 mm can be
loosened to allow the electronic

Make sure ALL 4 limit switches
make good contact with the
2 limit rings.
If factory wired jumpers are installed on
operator terminals, they must be
removed or operators will not function.
The operator MUST OPEN GATE upon initial power up
and OPEN command.
If the operator closes gate after giving first open
command, shut off power and reverse DIP-switch SW1,
switch 1 setting otherwise operator will NOT function
correctly.
