Configuring the Fault Recorder
The Fault recorder automatically records all fault events to
the Fault log file. It can be triggered via the embedded fault
detector, or externally through any of the 8 digital inputs.
The Fault recorder can be globally disabled or enabled in your
meter.
The Fault recorder setup allows you to adjust thresholds and
hysteresis for different fault triggers, and to define the
waveform and data log options for synchronous recording
during fault events.
To configure the Fault recorder:
1. Select Memory/Log from the Meter Setup menu, and
then click on the Fault Recorder tab.
2. Enable fault triggers suitable for your application.
3. If you wish to change the default settings, adjust
thresholds and hysteresis for your fault triggers.
4. Select the waveform and data logging options for fault
events.
5. Download your setup to the device.
