20.9 Troubleshooting
Answers are provided below for faults that may occur in practice:
Why does the Sunny Island not connect to the running generator?
• Is the AC disconnection unit on the generator ok?
• Has the power which is allowed to be fed back into the generator during the permissible time
been exceeded (parameter "233.14 GnRvTm")? If yes, "!" is displayed. Generator connection
is blocked for the set time. Set the parameter "540.02 GnAck" to Ackn.
• If the generator control relay (GnReq) is open has the generator been started manually
(parameter "234.07 GnStrMod")? Change the setting to autostart, if required.
• Is a GenMan used in the system?
– Check the return signal (DigIn)
– The generator can only be started manually using GenMan.
