LIMIT SETTING INSTRUCTIONS
To avoid serious injury or death DO NOT calibrate motor or operate door unless doorway is in sight and free of obstructions. Keep clear of opening while door is moving.
WARNING
WARNING
To avoid damage to the door system, set the limits according to the instructions on this page:
-DO NOT use the door for standard operation before the limits have been set.
-The slat curtain can be over extended when lowered, and alternatively, the slat curtain can be wound up against the bottom bar stop, both situations could cause
damage to the system.
-Be prepared to stop the motor at any moment while setting the motor limits.
WARNING
CAUTION
• Looking up at the bottom of the operator you will see two colored limit setting screws. One red and one white. Adjust them according to the guide below to find and set
the upper and lower limits.
NOTE:
Each motor has a Thermal Cut Off to prevent it from over heating. Factory set limit is about 4 minutes of operation. This is a thermal setting and not a timed setting.
The environmental condition of the job site will shorten the operating time before the Thermal Cut Off will activate. Allow at least 20 minutes of cooling time (it may take up
to 45 minutes) before the motor will return to regular operation.
