Overranges
Overranges are displayed as long as they exist
and cannot be acknowledged. An overrange exists
if at least one of the four voltage or current measurement
inputs lies outside their specified measuring range.
The "upwards" arrow indicates the phase where the
overrrange occured. The appropriate error message for
current path I4 is generated as shown below.
The “V” and “A” symbols indicate whether the overrange
occurred in the current or in the voltage path.
I = 7 Aeff
UL-N = 300 Vrms
Overrange limits:
A = current path
V = voltage path
Indication of the phase (L1/
L2/L3) with overrange.
The current phase l4
overranges occur as shown
in the figure below.
Examples
A = current path

in the current path of phase
2 (l2).

path L3.
