NOTE: The new DC logic board includes inputs for CTM (Cable Tension Monitor). Although, not required to operate the
unit, it is highly recommended to include Cable Tension Monitors (part #s: K41-0157-000 and K41-0156-000) in all
Jackshaft installations. The Cable Tension Monitor detects cable slack and will stop and reverse the door.
NOTE: Pusher springs should be used with the door system to help get the door moving in the Close direction. For
certain types of doors, such as standard lift, angled track may also be recommended. Please check with the door
manufacturer for details.
