4 Problems with the Device
Corrective Action
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.
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 flashing 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.
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.
