Statistics data of the maximum pointer
Maximum pointers are used for preventive diagnosis:
– The maximum measured value is stored in the device.
– The higher-level PLC can collect the measured value at any time.
– The higher-level PLC can delete the measured value at any time.
The following data are available as maximum pointers:
• Number of overload trips.
• Phase current I
L1max
to I
L3max
and I
L1min
to I
L3min
. The maximum and
minimum phase current are indicated as a percentage [%] of the set current I
e
and in amperes [A].
Data format: Each 1 byte, 8-bit current format.
The measured maximum and minimum phase current in bridging mode is
stored for each phase.
• Minimum and maximum phase-to-phase voltages U
Lx
- U
Ly
as r.m.s values in
0.1 V. Minimum and maximum line frequency in 0.5 Hz resolution.
