10.8 Mains signalling voltages
Mains signalling voltages are used by the network operator to communicate via the energy network using ripple control signals.
These differ regionally. Global settings (frequency of the mains signalling voltage, duration and trigger threshold) must be made
here for correct detection of these signals. These apply both to the standard parameter set according to EN 50160 and to the
individual PQ parameter set.
Frequency of the mains signalling voltage
Frequency of the ripple control signal, the 3-second mean value of which is compared with the limit.
Duration
Period over which compliance with the limit is monitored.
Trigger threshold
If this is exceeded, the duration of the monitoring starts. Specified as a deviation in% of the nominal voltage.
You will find the setting range and devault values in the chapter "PQ configuration" on page 51.
10.9 Factory reset
To reset the device to the factory settings, press button 1 (Option) for at least 10 seconds.
As soon as both LEDs go out, DEHNrecord SD restarts and is reset to the default values.
Warning: this will also reset the network settings.
