Overranges
Overranges are displayed as long as they exist and can-
not be acknowledged. An overrange exists if at least one
of the voltage or current measurement inputs lies out-
side 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 = 520 VL-N
Overrange limits:
A = current path
V = voltage path
Indication of the phase (L1/L2/
L3) with overrange. The cur-
rent phase l4 overranges
occur as shown in the figure
below.
Examples
A = current path

range in the current path of
phase 2 (l2).

range in current path l4
