Direction Control Modification
  
 

Direction Read Out Modification. From incremental to absolute enconder.

My previous tower control was was build in 2002. Because the incremental read did have a small % misreadout, I decided to install a absolute encoder with 1:1 drive


First I had to drill a hole.

      
 

The hole in the concrete was needed to place the alu rod of 6mm (0,235'') for coupling a 1:1 drive with the absolute encoder.

      
 

Centre the rod before using Hilti.

A high strength, two part adhesive epoxy with a long working (gel) time. Used in solid based concrete applications.

I designed a service friendly adjustable and removable decoder using two stainless steel (A2) plates.

The white box on the left within the remote unit.

      
 

Also using a flexcoupler for adjustment to the shaft.

Here you can see the way how easy it is to remove the decoder for service reasons. Just loosen the srews and remove the unit.
