Operation
?
Generator voltage and/or frequency are outside of the set limits. The Sunny
Island 5048 will not connect the generator to the stand-alone grid while this
situation exists.
! The maximum permissible generator reverse power has been exceeded
and the Sunny Island 5048 disconnected the generator from the stand-
alone grid.
The following letters indicate why the generator was requested:
B(attery)
Generator has been requested as a result of the battery charge level.
L(oad)
Generator has been requested as a result of the load-dependent generator
request.
S(tart)
Generator has been requested by the operator manually setting the
generator request in the Sunny Island 5048 from "Auto" to "Start". The
generator is then NO LONGER automatically controlled or switched off by
the Sunny Island 5048.
T(ime)
Generator was started for 1 hour via the "Run1h" setting at the Sunny Island
5048. Once this time has passed, the Sunny Island 5048 automatically
switches off the generator.
The generator status and the reason for the request are shown on the display
alternatively under "status of external sources".
If, for example, the display changes every 2 seconds from "*" to "B", this means
that the generator voltage and frequency lie within the specified limits and that the
generator was requested as a result of the battery charge level.
If the generator has been manually set to "Stop", then no generator status
information is shown on the display. The field remains empty.
The messages for both relays (filled in circle = activated / open circle = deactivated)
follows in the lower line.
The line ends with a warning display (!). This symbol blinks until you have viewed the
warning in the menu "#300 Diagnosis".
If faults occur, the device switches into standby mode and shows the fault on the
display. The fault must be remedied and then confirmed. The Sunny Island 5048 can
be restarted thereafter.
In the Home Screen, the Sunny Island 5048 also shows the following values in
succession (in 4-second intervals: parameter name for 2 seconds, parameter value for
2 seconds) in the upper line:
