Failure history
“FLh”
The PSU stores 30 last failures in non-volatile memory, which can be reviewed later.
In order to review the failures, use the "<" or ">" button to set the
FLh
parameter and confirm by pressing "OK".
The display will show the number of failure in the memory and its code. Pressing the "OK" button again will display
the next failure in the memory.
The memory of the new power supply remembers the events that are the result of the efficiency tests
carried out at the production stage.
-
press „<” or „>” button to set the „FLh” parameter on the display
-
press „OK” button
- number 1, indicating the number of failure in the memory (the highest priority),
will be displayed. Then, after one second, failure code will be automatically displayed
-
press „OK” button
- the number 2, denoting the next number of failure in the memory, will be displayed.
Then, after one second, the next failure code will be automatically displayed.
- if the memory has more failures, pressing the "OK" button will result
in displaying subsequent codes
-
the „- - -„ parameter on the display marks the end of the list of failures
5.2.4
Current failures
„FLc”
In case of abnormal electrical parameters, the power supply provides optical and acoustic indication of the
failure via corresponding LED and a beeper (if not disabled).
The PSU can simultaneously indicate several failures. Thanks to this solution, codes of all failures and their
priority can be previewed in the
FLc
menu. In the
FLc
menu, each press of the "OK" button on the panel displays
the next error code that caused the failure. If there are multiple failures at the same time, pressing the "OK" button
will display the next code. The display order of failures is arranged by priority of importance. The first failures in the
display order are of the highest priority.
Section 5.2.5 summarizes all the failure codes that may occur during the power supply operation. The
individual codes are accompanied by appropriate optical indication on the panel, acoustic indication and activation
of the dedicated technical output.
