The limit sensor activators MUST be
installed on BOTH ends of chain to
indicate the OPEN and CLOSE positions
of the gate or DAMAGE will occur. They
will activate the corresponding LIMIT
SENSOR (Gray or Black) when they
move within range, stopping the gate at
the desired positions.
The limit sensors have been FACTORY
INSTALLED for front mounting position.
If rear mounting position is being
installed, make sure the limit sensors
have been moved to the correct
positions (see below).

IMPORTANT: Cycle the gate OPEN and CLOSED AFTER the
limit sensor activators have been installed. Operator will cycle
slowly to LEARN the open and closed gate positions. After
the operator learns the gate positions, it will cycle at the
GATE SPEED selected for normal operation, see page 28.

Push and HOLD the JOG LEFT or JOG RIGHT buttons
accordingly on the MAX MC-200 motor controller to
move the gate (release the button to stop gate). This
allows gate to be moved back and fourth without leaving
the operator to “fine tune” the open and close gate
positions if desired.
“Fine Tune” Limits Adjustment
WARNING: Avoid moving gate while “Fine Tune” adjusting.
IMPORTANT: LEDs MUST light up when gate
reaches OPEN and CLOSE positions or operator
WILL NOT learn gate positions. If gate positions
are not learned, gate cycling speed will remain
slow during normal operation.
IMPORTANT: Remove breather pin from
gear reducer BEFORE cycling operator.
