IMPORTANT NOTE: To avoid danger of possible damage to the door and operator, limit switches must be adjusted to their approximate positions before applying power to the operator.
WARNING
NEVER PLACE HANDS OR TOOLS INSIDE OPERATOR OR NEAR MECHANISM UNLESS POWER IS OFF!!
Auxiliary limit switches to control other functions are also present and should not be confused with the -Aand -B- limit switches. There are two(2) limit nuts on the threaded shaft that transverse the shaft as the operator opens and closes the door. When a limit nut nears the end of the shaft, it activates a switch(es).
WARNING
A. Set Limit Direction Switch Open the cover on the electrical enclosure and locate dip switch SW1 on circuit board. The direction of the limit travel is determined by the switch SW1 - pole #2 setting.
B. Manually raise the door to a nearly open position. Depress the limit nut retaining bracket away from the slots in the limit nuts, and manually rotate to the OPEN limit nut until it depresses the OPEN limit switch lever (you can hear the switch click when the switch contacts transfer). Lubricate. * Check set screw tightness Check & tighten as required Check & Operate Check for wear & lubricate
