Switch position "P"
If the rotary coding switch is at the "P" position, the measured values of the power are output
via the four channels:
A01: Active power phase P
L1
A02: Active power phase P
L2
A03: Active power phase P
L3
A04: Total apparent power S
total
To calculate the full-scale deflection value of the active power per phase, the value of the
rating plug must be multiplied by the rated voltage of the system. The full-scale deflection
value is then subdivided into a value range shown in the table below.
For the total apparent power and the total active power (position f), the calculated value still
has to be multiplied by 3 before the full-scale deflection value can be read from the table.
The table below gives the value ranges for power [W/VA]:
