The torque motor drive ships from the factory completely assembled, ready to install into the batten tube. In addition, the torque motor
drive’s drive tube alignment is preset at the factory. Field adjustment should not be required. Start by referring to the installation drawing
for the motor location (drive end). Position the torque motor drive assembly at the drive end of the curtain batten tube with the drive tube
grooves in alignment with the batten tube keys. Slide the assembly into the batten tube until the limit collar of the drive assembly is near
the end of the batten tube. At this point, ensure the machined crown slot is engaged with the motor limit key, and the flanged end of the
crown is against the torque motor limit collar’s flange. See detail below. Now, with the machined crown grooves rotated and aligned with
the batten tube keys, insert the torque motor fully until the machined crown’s flange is tight against the end of the batten tube. To secure
the torque motor drive to batten tube, carefully drill two (2) 13/64” dia. holes approximately 180 degrees apart and exactly 25 5/8” from
the end of the batten tube. See drilling detail.
Note: Drill through two walls only (the batten tube wall and the outer drive tube wall)!
Install two (2) pop rivets. See Figure D.
