Rotor controller

The design of the front and back starts with a drawing program in which 1:1 scale the design is projected. All dimensions are measured accurately.

     
 


     
  Counter

The SLE-73 meter is designed exclusively for applications (NCRT) where a progressive counting of impulses is required. Its feature two entry ports: counting and with a programmable function that can be used for resetting the meter to zero or stopping / changing its direction of travel (as required).The built-in entry port divisor with programmable value from 1 to 9999, along with an adjustable decimal point, permits a
simple transfer of incoming impulses into the units required. The counter can be configured with the local keyboard or free S-Config software via RS-485 comm port.
     
       
  Modeling

After printing the design onto standard paper, the components has been placed at the correct position. In this case the 1-0-1 switch is to close to the CW/CCW so that the design has to be redrawed. Using preassmabled 24V LED which are rather cheap and saves the trouble of tinkering with small connections of the LED
     
       
  Punching

the printed model is placed over the aluminum plate and with a punch, small reference making holes are punched in the cover
     
       
  Edit material

Drilling and the old-fashioned handiwork of files and drills...
     
       
  Positioning

The SLE-73 meter is supplied with brackets which will have a screw-free connection from the front.
     
       
  Backcover

The same procedure as the front cover. When this is finished I am using a hole punch for better position the model.
     
       
  Standard Power Supply

I use industrial components such as the Mean Well switched power supply MDR20-24VDC-1.00A.
     
       
 

Labeling

Cleaning the surface with alcohol and slighly heating the aluminium plate to ensure the best adhesive.

The final design is printed in full color on AN Avery 3655 LABEL. Cutting the model firmly and applyling it to the front and back.

     
       
 

Onlay

the final finishing is done by sticking a transparent foil over the label.

After this has been done, the components are placed with caution.

     
 

     
  9POL dSUB

Wiring the 9-pol DSub connector and testing the remote control unit close to the mainunit with external 24VDC.
     
  Result

The result is a cheap but professional looking control box for controlling the NCRT
     
 

Modification DRV and SPD

Added tweo extra LED's which signal refers to the drive (DRV when its turns) of the V1000 and when the drive frequency has reached the setpoint (SPD = 30Hz) These signals are directly supplied from the drive controler.

Replaced the "snap-in'' LED's for those one's which can fixed with a nut.

     
 

New and Old

Previous home made rotating tower control boxes with different methodes of readout and drive.
