Fig. 12. Screen of the history of PSU’s parameters.
In order to change the displayed parameter, highlight its name by pressing the „SET” button and use the
„<” or „>” buttons to choose the requested parameter. Pressing the „SET” button again will highlight the time
range of the chart, which also can be changed with the „<” or „>” buttons. Pressing the „SET” button again will
enable moving the cursor (vertical dotted line on the chart) along the time line with the „<” or „>” buttons. The
values of current parameter and the recording time pointed by the cursor will also be highlighted.
Among the available positions on the chart, it is possible to view the following values:
- current - the value measured at the end of the measuring cycle
- minimum - the lowest value measured during 5 minutes
- maximum - the highest value measured during 5 minutes
of the following parameters:
- U
AUX
- AUX output voltage
- U
AUX MIN
- AUX output voltage - minimum
- U
AUX MAX
- AUX output voltage - maximum
- I
AUX
- output current
- I
AUX MIN
- output current, minimum
- I
AUX MAX
- output current, maximum
To optimally read and analyze the values shown in the chart, it is possible to change the time range on the
bottom axis of the chart. The following ranges are available:
<8h>
<24h>
<2days>
<week> (weekly)
5.4.5 LCD screen – history of events
In case of abnormal electrical parameters during the operation, the PSU will indicate a failure by displaying
a message on the LCD, periodically turning on and off the LCD backlight, turning on the red LED ALARM on the
panel, activating acoustic indication (if enabled) and changing the status of a dedicated technical outputs.
To choose the history of events screen, press the „ESC” button, use the „<” or „>” buttons to choose the
icon and press the „SET” button to confirm.
Fig. 13. The history of events screen.
The history of events screen enables overviewing the events recorded by the internal diagnostic system.
The internal memory can store up to 2048 events, carrying information about the fault type, time of occurrence and
the values of other electrical parameters. In addition, the diagnostic system assigns the failure code for a particular
event on the basis of the stored parameters.
In order to preview the history of events, use the „<” or „>” buttons. It can be done in two modes: short
mode(date, time, code, fault description) or full mode - with additional information about electrical parameters and
status of inputs and outputs. To switch between the modes, press the „SET” button.
