4.12 Overflow of Measured Values

4.12 Overflow of Measured Values
If the measured values determined in a measurement circuit are higher than the possible values
of the parameterized measuring range, a value overflow will be displayed. In addition, this value
overflow is signaled via Modbus or IEC 60870-5-103 protocol.
The overflow is displayed or transmitted if the nominal AC voltage or AC current values are
exceeded by 20 %.
Presentation of the measured value overflow in the display
An overflow of the measured values AC voltage and AC current, as well as the derived quantities
such as active power, reactive power, harmonic, power, THD and cos φ is displayed by ***. The
energy counting is only stopped, not reset.
Transmission of the measured value overflow using the Modbus protocol
A special Modbus register (register address 40200) has been reserved for the transmission of
the measured value overflow. For detailed information, please see the Powermeter SICAM P -
Modbus manual (order no. E50417-B1076-C241).
Transmission of the measured value overflow using the IEC 60870-5-103 protocol
The measured value overflow is transmitted using the IEC 60870-5-103 protocol. For detailed
information, see the Power Meter SICAM P 7KG7750/55 - Communication Protocol IEC 60870-
5-103 manual (order no. E50417-B1000-C375).
