Hi Jan, PE0SAT

The G-5400 has the starting AC capacitor C installed into the control box
only for the azimuth motor wich is a KR-400 and obviously there is not limit
switch into the azimuth rotator KR-400
Instead for the Elevation motor the starting capacitor C is located inside
the rotator and there are limit switches.

The G-5500 has the capacitors C installed into the rotators one C for the
azimuth and one C for the elevation.
In addition there are limit switches both for azimuth and elevation.

The G-5600 is like the G-5500 with capacitors C installed into the rotators
and there are limit switches both for azimuth and elevation.

If you want to use the G-5600 controller with an old KR-400 for azimuth and
a KR-500 for the elevation you must connect an AC capacitor of 100 uF 70
volt across terminals A4 and A5 of the controller for the azimuth and
another 100 uF 70 volt capacitor across terminals E4 and E5 for the
elevation.

A capacity for C of  50 uF and 70 volt insulation will work equally well.
Since the above capacitors are relatively big in size I suspect that there
is no room to put them into the controller and if so they should  be
connected outside the controller across the above mentioned terminals.

The rest of the controller don't need modifications.

In a separate email I will send to you the original schematic diagrams of
the above rotators.

Have fun and 73" de
