Statistics data of the maximum pointer
SIRIUS 3RW44 System Manual
GWA 4NEB 535 2195-02 DS 04
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 is available as maximum pointers:
• Number of overload trips.
• Phase current I
L1max
minimum phase current are indicated as a percentage [%] of the set current I
and in amperes [A].
Data format: 1 byte, 8-bit current format each
The measured maximum and minimum phase current in bridging mode is
stored per phase.
• Minimum and maximum phase-to-phase voltages U
0.1 V. Minimum and maximum line frequency in 0.5 Hz resolution.
