Description Information Corrective Action
Display failure. After selecting any key, the whole display
remains dark or the display is defective.
Check the following issues:
• Is the supply voltage connected? This is the case•
when the System LED is illuminated.
• Is the environmental temperature within the allowed•
range?
• Try to adjust (increase / decrease) the contrast of the•
display by using PowerPort-E.
•
If all these checks do not yield any results, send the
•
device back to the manufacturer.
The Self-Supervision Contact has opened. An open Self-Supervision Contact indicates that
no protection functions are active (anymore).
In general, the Self-Supervision Contact is closed only
during normal operation (and with active protection
functions), and this is also indicated by the System LED
shining in green color, or ashing red+green. See also
╚═▷ “3 System LED Signals”.
• Check whether there is an obvious cause, e. g.•
outage of power supply.
•
Check whether the device is booting, or has been
•
started into the special Bootloader mode. (In these
cases the Self-Supervision Contact gets intentionally
opened.)
If these mentioned reasons can be excluded the device
has detected a severe internal fault, that could not
be solved by an automatic restart. Since no protection
functions are being active it is strongly recommended to
replace the device by a new one as soon as possible, and
the device should be sent back to the manufacturer for a
detailed fault analysis.
Failure of a relay output. The physical status does not match the reported
state, as it is being shown via HMI or PowerPort-
E.
Check the following issues:
• Is the output in latched state? If yes, acknowledge•
(reset) the latching.
• Is the inverting parameter »Inverting« set to “Active”•
for the particular output?
• Check the wiring.•
