Indications
General
During operation, indications deliver information about operational states. These include:
•
Measured data
•
Power-system data
•
Device supervisions
•
Device functions
•
Function procedures during testing and commissioning of the device
In addition, indications give an overview of important fault events after a failure in the system. All indications
include the date, time, and it's state.
Indications are saved in logs inside the device and are available for later analyses. The following number of
indications are saved at least in the respective buffer (depending on the scope of the indications):
•
Event log 5000 indications
•
Fault log 100 indications
•
Waveform log 20 indications
•
Data log average values of current, voltage, and power (where applicable)
If the maximum capacity of the user-defined log or of the operational log is exhausted, the oldest entries
disappear before the newest entries. During a supply-voltage failure, recorded data are securely held by means
of storage in the memory. You can read and analyze the log from the device with Reydisp Manager 2. The
device display and navigation using keys allow you to read and analyze the logs on site.
Indications can be output spontaneously via the communication interfaces of the device and through external
request via general interrogation.
