Rectifiers are identified via their respective serial number which are accessible via the MMI
(display) and also via SNMP and HTTP.
If a rectifier is added this will be found and the number of registered rectifiers incremented.
If a rectifier is removed this will cause the number of registered rectifiers to be decremented and
a Comms lost alarm raised if the alarm has been enabled in the configuration.
Energy Metering, Logging
Energy metering function
The EFX48 utilizes the independent current readings from each load output in order to record
energy usage in kWh.
Bus voltage (V), individual load currents (A), total and per load output powers (W) are
available as live readings, via SNMP and the web pages.
There are 7 energy meters, one for each output and a total load energy meter. Each energy
meter has a range of 99999.99kWh and resolution of 0.01kWh, which for a total load of 2kW
gives a roll over to zero of 5.7 years. Each energy meter will sample at the Energy log sampling
rate and update to non-volatile memory at a user configurable interval.
The energy meters are held in non-volatile memory but the configurable memory update time
can cause a short gap in energy accumulation through a total system power cycle.
Energy meters can be read and reset via HTTP or SNMP and can be viewed on the web pages
and on the MMI.
Data Logging
The EFX48 includes a log of 10,000 events that can be downloaded for inspection on an external
device.
Event Logging, Data Logging and Energy Meter logging are all contained in the single log
which makes correlating system events easy and convenient.
The log is held in non-volatile memory which is updated at configurable intervals and will
remain uncorrupted through any form of power cycle, although the memory update interval
can cause a short record gap through a total system power cycle.
The log is accessible via SNMP and the web pages.
The log may be cleared by a user with Admin access via HTTP(S), by entering “0” into the
“Download from entry” box. In this case the first entry in the cleared log will record the Log
Clear event with the User ID and date/time.
When the log is full the EFX48 will delete the oldest entries in order to make space for new
entries. Approximately 2% of the log will be deleted.
Event Log entries
There are 3 different types of event log entries :
• Event Log entries
• Data Log entries
•
Energy Log entries
The Event Log entries include:
•
Power on events (system started)
