Messages of the Sunny Display in case of a failure
In case of a failure the Sunny Display switches to „ Failure“ and
the background illumination is activated.
The bottom line indicates the type of failure for 5 seconds.
Failures that result from a specific value that e.g. exceeds a
limiting are specified with the value that caused the failure as well
as the current value.
The normal operating data is displayed after 5 seconds.
The display starts from the beginning again in case the failure is
still present. Chapter 6.4 „ Measurement Channels and
Messages” (page 34) gives more detailed information
concerning the failure messages.
“Failure ROM“ indicates that the Sunny Boy has detected a
defective firmware in the EPROM. Contact SMA in order to
remove this failure.
Indication of DC Overvoltage
A too high voltage on the input (DC) side is indicated with a
blinking background illumination and the display shown on the
side.
Disconnect the Sunny Boy from the supply voltage immediately.
The Sunny Boy can otherwise be severely damaged.
Check the input voltage and your module configuration before
you reconnect the DC voltage to the Sunny Boy again!
