9.7 Consulting inverter statistics and manufacturer data
In order to consult the inverter statistics, go to [/Welcome/ESI Monitoring]. This menu
allows to monitor the inverter load and to get an idea of its operating point compared
to the nominal rating of the inverter. In addition, logged warnings, faults and events can
be retrieved for troubleshooting the inverter operation and any abnormal network
conditions. Also, an indication is given of fan running hours and inverter running hours.
The ‘ESI Monitoring’ menu can also be used to verify the status of the individual units in
a multi-master units system.
The ‘ESI Monitoring’ menu is discussed in depth in
Section 7.10.
In order to obtain background manufacturer data on your ESI, go to [/Welcome/User
interface/About ESI]. This menu gives basic data on the inverter. This data includes:
−
Basic manufacturer settings such as inverter type, maximum voltage rating and
ESI-S serial number. These settings can be accessed in [/Welcome/User
interface/About ESI]
−
Firmware version numbers for the ESI-Manager, the
µ
controller and the DSP
controller
When communicating with your ABB representative on a specific inverter, please provide
always the data shown in the ‘About ESI’ menu.
9.8 Inverter behavior on fault – retrieving error information
Under normal conditions the inverter is either running or stopped and the ESI-item in the
ESI-Manager ‘Welcome’ screen shows the message ‘START’ or ’STOP’. In this case, if the
inverter is stopped it can be started and if it is running it can be stopped. The start and
stop commands will be stored in the event log accessible in [/Welcome/ESI
Monitoring/Event logging].
All faults that occur are stored in the same event log. A fault can either be non-critical or
critical.
−
A non-critical fault is a transient fault (e.g. a voltage spike). When a non-critical
fault occurs the inverter may stop the switching of the IGBTs momentarily (< 40
ms) but they will automatically restart. The only way to pick up this type of fault
is to analyze the event log. Given the transient/random character of this type of
fault, the inverter performance will hardly deteriorate when it occurs.
−
A critical fault is a fault that after occurrence cannot be successfully automatically
cleared by the system within a reasonable time. The time frame considered
depends on the error type. If the fault is considered critical by the system, the
label ‘Critical’ will be shown in the event logging window. In addition, the ESI-item
in the ESI-Manager ‘Welcome’ screen will show the label ‘ACK. FAULT’. Note
however that if the fault disappears fast, this label disappears too. Depending on
the type of critical fault and the number of occurrences, the inverter, when
running, may either:
