Example: a V.T. with a 660V primary and a 100V secondary (660/100V)
means a ratio (P-S value) of 6.6. The position of the decimal point has
been previously selected as 11.1 to perform a V.T. ratio from 0.1 to 99.9.

Lo.A
: programming of the minimum electrical scale of the analogue
output. Value to be expressed as % of the output range (20mA, ±20mA,
±10mA, ±5mA, 10V, ±10V, ±5V, ±1V) to be generated in correspondence
with the minimum measured value (Lo.E parameter). Value programma-
ble within the range:

Lo.A
≤
99.9.
Example: (0/20mA output) “Lo.E” = 0kW that must correspond to an
output signal of 4mA.
“Lo.A” (%) = 100 x?mA
20
that in our example corresponds to 100x4mA/20 = 20%; then enter 20.0.
Example: (0/10V output) “Lo.E” = 0kW that must correspond to a
retransmitted signal of 1V.
“Lo.A” (%) = 100 x?V
10
that in our example corresponds to: 100x1V/10 = 10%; then enter 10.0.
Example: (±10V output) “Lo.E” = -100kW that must correspond to a
retransmitted signal of -10V.
“Lo.A” (%) = 0
that in our example corresponds to an output of -10V when we have the
minimum of the range as electrical input.
