Additional setup for trackless tilt

doors (jamb fittings) only

The aim of these steps is to make the opener push in the direction that the door edge is

moving. Preferably the door edge is being forced upward slightly as the closing cycle begins.

You must adjust the top limit of travel so that if you sight along the fully open door the sight

line intersects the pole in front of the trol-

ley - not behind the trolley.

If the door does not open far enough af-

ter setting the top limit of travel correctly

then it will be necessary to make some

installation changes. You will need to try

some or all of: raising the location of the

header bracket further, lowering the power

head further or increasing the length of

the door arm further.

WARNING The door is not safe for un-

supervised operation until the force sensitivity has been be set.

Setting the force sensitivity

STEP 1: Remove the lamp cover by turning the catch on its underside. Remove the green

control panel cover.

STEP 2: Identify the green and the red control knobs marked open-force and close-force.

Note: The opener can be set to either determine its own safe operating force level, or it can

STEP 3: Press and hold the green operate button to move

the door up and down into the required fully open or fully

closed positions. Each time the operate button is pressed

the door will stop or move in the opposite direction.

STEP 4: When the door is at the fully closed position, turn

the down-limit screw (located adjacent to the courtesy lamp)

until the red close-LED stays on continuously.

STEP 5: When the door is at the fully open position, turn

the up-limit screw (located adjacent to the courtesy lamp)

until the green up-LED stays on continuously.

STEP 6: If the door can not be moved sufficiently far then

look at the red and green LEDs. If one of these is on con-

tinuously then the door has stopped at a limit point. Adjust

that limit to allow more travel. One turn of a limit adjust-

ment screw results in 250mm of door travel.
