15.7 Performance characteristics of functions
The measurements are made via current transformers ../5 A with a frequency of 50 / 60 Hz.
INFORMATION
Note on saving measured values and configuration data:
Since the following measured values are stored in a non-volatile memory every 5 minutes, an
operating
voltage failure
can result in an interruption of the recording of max. 5 minutes:
·
Comparator timer
·
S0 meter readings
·
Min. / max. / average values
(without date and time)
·
Energy values
Configuration data is saved immediately.
A detailed Modbus address and parameter list can be found at www.janitza.com.
