F.
HOW TO: SET AND ADJUST UPPER AND LOWER LIMITS
1.
ALWAYS SET THE LOWER LIMIT FIRST
2.
USE THE DOWN ARROW ON THE REMOTE TO MOVE THE BOTTOM BAR DOWN. IF THE BOTTOM
BAR DOES NOT STOP BEFORE 1’ FROM THE BOTTOM, PRESS THE STOP BUTTON TO STOP IT 1’
FROM THE BOTTOM.
3.
THE WHITE RECTANGULAR BLOCK ON THE VISIBLE END OF THE MOTOR HAS TWO HOLES
CONTAINING THE LIMIT ADJUSTMENT SWITCHES. THE LIMIT ADJUSTMENT SWITCH THAT
CONTROLS THE LOWER LIMIT IS ALWAYS IN THE TOP HOLE REGARDLESS OF WHICH SIDE (left or
right) THE MOTOR IS MOUNTED. ABOVE THE TOP HOLE, THERE IS AN ARROW ABOVE THE PLUS
(+) SIGN AND THERE IS AN ARROW ABOVE THE MINUS (-) SIGN. TURNING THE LIMIT
ADJUSTMENT TOOL IN THE DIRECTION OF THE PLUS (+) ARROW or the counter-clockwise
DIRECTION INCREASES THAT LIMIT AND TURNING THE LIMIT ADJUSTMENT TOOL IN THE
DIRECTION OF THE MINUS (-) ARROW or the clockwise DIRECTION REDUCES THAT LIMIT.
4.
NOW ADJUST THE LOWER LIMIT:
1. IF THE SCREEN STOPPED BEFORE IT GOT TO
WITHIN 1' OF THE BOTTOM
2. IF YOU HAD TO STOP THE SCREEN BEFORE
IT GOT TO WITHIN 1' OF THE BOTTOM
1-A. YOU HAVE FOUND THE FACTORY-SET
TEMPORARY LOWER LIMIT. HOWEVER, THE
FACTORY-SET TEMPORARY LOWER LIMIT IS
TOO SHORT. SO, YOU NEED TO INCREASE THE
LOWER LIMIT POSITION
2-A. THE FACTORY-SET TEMPORARY LOWER
LIMIT IS SET TOO LONG. THEREFORE, YOU
NEED TO REDUCE THE LOWER LIMIT POSITION.
1-B. PLACE THE LIMIT ADJUSTMENT TOOL
INTO THE TOP HOLE ON THE END OF THE
MOTOR. TURN THAT LIMIT ADJUSTMENT
SWITCH IN THE DIRECTION OF THE PLUS (+)
ARROW or the counter-clockwise DIRECTION.
THE BOTTOM BAR WILL JOG DOWN WITH
EACH TURN. CONTINUE TO TURN UNTIL THE
BOTTOM BAR REACHES THE DESIRED LOWER
POSITION. AT THAT POINT YOUR LOWER LIMIT
IS SET.
2-B. PLACE THE LIMIT ADJUSTMENT TOOL
INTO THE TOP HOLE ON THE END OF THE
MOTOR. TURN THAT LIMIT ADJUSTMENT
SWITCH IN THE DIRECTION OF THE MINUS (-)
ARROW or the clockwise DIRECTION FOR 25
COMPLETE TURNS.
Note: 7 complete turns of the Limit
Adjustment Tool results in one complete
rotation of the screen tube.
2-C. USING THE REMOTE, RAISE THE BOTTOM
BAR 2 FEET AND THEN LOWER IT. IF IT DOES
NOT STOP BEFORE IT REACHES 1' FROM THE
BOTTOM, STOP IT 1' FROM THE BOTTOM.
2-D. REPEAT STEPS 2-B AND 2-C UNTIL THE
BOTTOM BAR STOPS BY ITSELF. WHEN THE
BOTTOM BAR STOPS BY ITSELF YOU HAVE
FOUND THE TEMPORARY LOWER LIMIT.
2-E. PERFORM INSTRUCTION 1. (1-A AND 1-B)
ON THE LEFT COLUMN OF THIS TABLE OF
INSTRUCTIONS TO FINE TUNE THE LOWER
LIMIT.
