LIMIT SWITCH ADJUSTMENT INSTRUCTIONS
Check to ensure there are a minimum of three wraps of cable on the drum(s).
2. Check to ensure that the hardware that secures the micro switches in the box is fully tightened. IT WILL
nuts left or right.
NOT BE POSSIBLE TO MOVE THESE SWITCHES - all adjustments will be made by moving the traveling
1.
3. Run the curtain or backstop to the desired down position. Ensure
that there is no slack in the cables. The bottom of the curtain
should be between 1" and 3" above the finished floor or the
backstop brace hinge should be fully extended and locked.
Depress the pressure lock guide plate down (use fingers only - use
no tools) and turn the right-hand traveling nut until the "DOWN" limit
switch engages (listen for the click). Turn the nut an additional full
revolution toward the limit switch. See Detail "B". Check to ensure
that the tab on the pressure lock guide plate engages a notch in the
traveling nut. See Detail "C".
4. Raise the curtain or backstop to the desired storage position.
IMPORTANT NOTE - Allow a MINIMUM of 8" clearance to any
overhead structure, ceiling, lights, or other equipment.
5. Depress the pressure lock guide plate once again (use fingers
only - use no tools) and turn the left-hand traveling nut until the
"UP" limit switch engages (listen for the click). Turn the nut an
additional full revolution toward the limit switch after it engages.
Check to ensure that a notch in both traveling nuts is seated firmly
on the tab on the pressure lock guide plate. See Detail "C".
6. Operate the unit up and down several times over the full range of travel, to adjust and fine-tune both the up
and down limits, until the limits are set correctly.
7. After all adjustments are made, once again check to ensure that both traveling nuts are seated properly on
the tab of the pressure lock guide plate. See Detail "C".
8. Operate each curtain or backstop through THREE COMPLETE UP-DOWN CYCLES, to ensure the cable (or
strap) has seated properly on its drum. Afterwards, make additional adjustments to the limit switches as
required, according to the instructions on the previous page.
11. Demonstrate the operation of this unit to an individual at the site who is responsible for the safe operation
and maintenance of this equipment. Hand this instruction sheet to that individual, to keep for future reference.
Point out the safety concerns and the necessity of using a Porter key switch or control system in the event that
same has not been installed.
