  • Page 12: Installing The Support Rope

    Edition February Installation Manual OMEGA 2020 Installing the support rope  Feed the support rope into the lower tube and make sure the tension rope engages well into the motor drive wheel. Make sure you put some cover on the lower floor so the support rope does not get dirty when it gets out on the lower tube end.
  • Page 13 Edition February Installation Manual OMEGA 2020  Loosen this spring – move the safety nut to the end of the screw. After tensioning the cable put the safety nut back into its original position. Move nut  Now you need to define the right length of the support rope. Approach the over speed governor tube to the lower rail end to measure necessary support rope element length.
  • Page 14 Edition February Installation Manual OMEGA 2020  It is important that there are not too many support elements on the support rope as then it is not possible to tension the cable. A gap between the last support element and the fixing bracket of the support rope is ideal. This gap depends on the length of the rail and number of curves and is later reduced when the rope is tensioned! Below a table that shows approximate gap length based on rail length.
