SETTING THE LIMITS
Travel limits regulate the points at which the door will stop
when moving up or down. Follow the steps below to set the
limits.
NOTE: The door must be in the mid or closed position to
begin setting the limits.
TURN POWER ON.
Setting the limits :
1. Press and hold the black button until the yellow indicator light
starts flashing slowly then release.
2. Adjust the position of the door to the desired up position by
using the black button. Black moves the door UP (open) and
orange moves the door DOWN (close). Check to be sure the
door opens high enough for your vehicle.
3. Push the transmitter or door control. This sets the UP (open)
limit and begins closing the door.
Immediately press either the orange or the black button. The
door will stop.
Adjust the desired DOWN (close) limit position using the black
and orange buttons. Check to be sure the door is fully closed
without applying excessive pressure on the rail (rail should not
bow upwards and the chain/belt should not sag or droop below
the rail). Push the transmitter or door control. This sets the
DOWN (close) limit and begins opening the door.
4. Open and close the door with the transmitter or door control 2
or 3 times. Leave door in the open position ready for force
setting.
NOTE:The force must now be set in order to complete your
installation (refer section 23).

SETTING THE FORCE
The force, as measured on the closing edge of the
door, should not exceed 400N (40kg). If the closing
force is measured to more than 400N, the Protector
System (IR Beams) must be installed (refer section
TM
26).
The force setting regulates the amount of power
required to open and close the door.
1. Locate the orange button (2).
2. Push the orange button (2) twice to enter unit into Force
Adjustment Mode. The LED (3) (indicator light) will flash
quickly.
3. Push the programmed transmitter (4) or push bar on the
door control that was shipped with your opener. The door
will travel to the DOWN (close) position. Push the
transmitter (4) again, the door will travel to the UP (open)
position.
The LED (3) (indicator light) will stop flashing when the
force has been learned.
The door must travel through a complete cycle, UP and
DOWN, in order for the force to be set properly. If the unit
cannot open and close your door fully, inspect your door to
insure that it is balanced properly and is not sticking or
binding.
