– 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

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.

Section 6.4.6 lists all codes that may occur during the operation of the PSU. The individual codes are
accompanied by appropriate optical indication on the panel, acoustic indication and activation of a dedicated
technical output.
The memory of the new power supply remembers the events that are the result of the efficiency tests
carried out at the production stage.
