Display of LED Error
The display of the LED Error depends on the firmware version of the device.
Devices up to firmware version 33407 of the IO-CPU are flashing in the case when an
overtemperature is detected. Other faults will not be signaled.
Device with firmware version 33408 or newer of the IO-CPU have different blink
codes displaying differnt faults. Are there multiple faults only one fault will been
shown.
9.1
Sequence of the blink code
The blink code consists of 6 bit and a sychronisation. A bit will be shown by a
short
signal
or a
long signal
. Between the bits is a
pause
. After the 6 bits have been
transmitted the synchronisation is shown with a
End signal
and a
End pause
. After
the synchronisation the blink code will be repeated. It will always complete blink
codes transmitted.
The blink code has 5 differnt signals:
Short on:
short signal
, Duration duration 50 ms, indicates a logical 0
Medium on:
long signal
, Duration about 500 ms, indicates a logical 1
Long on:
end signal
, duration about 2000 ms, End of the code
Short off:
pause
, duration about 1000 ms, after a bit
Long off:
end pause
, duration about 2000 ms, End of the code
9.2
Meaning of the blink codes
In the following illustrations, the diagrams correspond qualitatively to the sequence
of the blink code.
9.2.1
Loss of communication with the LT-CPU
Error number: 1
If this code remains after power off and on of the device a board is defect and the
device must be sent in for repair.
9.2.2
Failure of the power converter
Error number: 2
Is intermedient in the case of an overload. If the overload disapers the failure will go
away within 10 s.
If this code remains after power off and on of the device a board is defect and the
device must be sent in for repair.
