2.14 Programming of nominal voltage and current inputs
and ratios.
The program allows the user to program the nominal
voltage and current inputs and ratios. Please note the ratios
can be changed as long as the secondary (the input to the
M560) stays as shown on the data label which is on the side
of the product. For example if the M560 had been set by the
factory to have a C.T. ratio 200/5A and the change required
was for the input C.T. ratio to be 500/5A this can be
achieved by program changes. But if the change required
was for a C.T. ratio 500/1A then the unit would have to be
returned to the factory or distributor to have the internal
C.T. changed from 5A to 1A. The same applies to the
voltage if the M560 input voltage is 110 Volts L.L then an
external voltage transformer ratio can be programmed as
long as the nominal input to the M560 stays at 110V L-L

For example if the input was originally programmed for
6.6kV/110 and a V.T. of 11kV was required then this change
could be achieved through software. (See example below)
