Screen of the history of PSU’s parameters.
In order to ch
ange 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
-

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>

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.
