An inconsistent opening is normally caused by the arm not being installed correctly. The arm must be installed while the operator gearbox is in the full open position, and the door at 90° open position.
The following step are used to properly install the arms on the Benchmark 9100 Series and Falcon 8200 Series operators.
1. Make sure the Operator Power is connected and the operator turned on.
2. Install a jumper across the control box Main Act and Main Act Com.
3. The operator motor will activate and drive to the Full Open position, and remain there.
For Push Arm Installation:
4. Open the door to 90°, and attach the Main Arm to the operator spindle at 90° to the opening (+/- 10°) with the 8mm socket head screw.
5. Remove the arm locking screw from the Rod & Shoe. Attach Rod & Shoe to door. Insert rod into forearm tube and reinstall the arm locking screw loosely. With the door open to 90°, tighten the arm locking screw.
6. Undo the jumper that is across main activation inputs and let the door shut. After the door is closed, attach the actuators. Momentarily push the actuator, the door should open to 90, stay open for 5 seconds at least and then close.
For Pull Arm Installation:
4. Slide the pull arm roller into the track, then insert a track end cap on each end of the track and install track to door.
5. Attach the Pull Arm to the track roller with the roller locking screw and to the operator spindle loosely with the 8mm socket head screw. Open the door to 90° and tighten the 8mm socket head screw.
6. Adjust arm if required. Due to the mesh of the arm to operator spindle, the door may be open to slightly more or less than 90°. To adjust arm, remove arm adjustment screws, push door open to 90° and reinstall arm screws.
7. Undo the jumper that is across main activation inputs and let the door shut. After the door is closed, attach the actuators. Momentarily push the actuator, the door should open to 90, stay open for 5 seconds at least and then close.
