All analog outputs are updated at a 1-cycle rate.
See Configuring Analog Outputs in Chapter 5 on how to
configure analog outputs in your meter.
Operating the Logical Controller
The embedded logical controller allows monitoring any
measured quantity or external contacts to provide indication,
counting and recording events whenever the value exceeds
the predefined threshold or when a status transition is
detected on the meter inputs. It provides a 1/2-cycle
response time for fast analog and digital triggers.
The controller can monitor internal diagnostic events and
meter operation status to give a fault indication via relay
outputs or provide cross triggering multiple devices.
All controller operations can be recorded to the meter Event
log with indication of the event time, source and a trigger
value.
See Using Control Setpoints in Chapter 5 on how to configure
the meter logical controller for your application.
Operating the Event Recorder
The Event recorder automatically records time-tagged self-
supervision events related to configuration changes, resets,
and device diagnostics.
It can also record setpoint-monitored events and setpoint
operations for setpoints individually configured for triggering
the Event recorder.
See Configuring the Event Recorder in Chapter 5 for more
information.
Operating the EN50160 Power Quality Recorder
The EN 50160 Power Quality (PQ) recorder provides
EN 50160 power quality statistics for EN 50160 compliance
reports, and long-term harmonics survey statistics for
trouble-shooting harmonic problems throughout an electrical
network. It also records time-tagged voltage disturbances
and voltage fault events into the Power Quality event log.
All power quality triggers have programmable thresholds and
can be adjusted for a specific application.
The PQ recorder is configurable for triggering the Waveform
recorder to record fault voltage and current waveforms
before, within and after an event, and can also trigger the
Data recorder for long-duration profiling of RMS voltages and
currents while the event continues, using a variable recording
rate and variable averaging intervals.
See Configuring the EN50160 Recorders in Chapter 5 and
EN50160 Evaluation and Recording in Appendix F for more
information on configuring and operating the PQ recorder.
