SMA America, LLC 10 Operation
Operating Manual SI4548-6048-US-BE-en-20 91
10.7 Parameter Display
Parameters on the Sunny Island are displayed as follows:
In the upper line, the parameter number comes first, then
a separator (hash) followed by the parameter name. In
the lower line, there is the value with the unit and the
modification mark (enter arrow) is on the far right.
"Start" request reason:
The generator has been requested by the operator manually setting the generator
request in the Sunny Island from "Auto" to "Start". The generator is then no longer
automatically controlled or switched off by the Sunny Island.
"Time" request reason:
The generator was started for one hour using the "Run1h" setting in the
Sunny Island. Once this time has passed, the Sunny Island automatically switches
off the generator.
Display for relay (solid circle = relay is activated; empty circle = relay is
deactivated)
Warning message is displayed (at position (H):
This symbol blinks until you have confirmed the warning or the error in the menu
"410# Failures Current" or "420# Failure History".
Display "Generator Status" and "Request Reason"
The two displays above are cyclically shown on the display as the status of the external source.
Example:
If the display changes every three seconds from "*" to "B", this means that the generator voltage
and frequency are within the set limits and that the generator was requested as a result of the
battery state of charge.
Stopping the generator manually
If the generator has been manually stopped, no generator status information is displayed. The
field remains empty in this case.
Indications of a warning
If faults occur, the device switches into standby mode and shows the fault on the display. The
fault must be eliminated and confirmed, then the Sunny Island carries out an autostart.
Parameter/value list
If you would like to switch from a menu (regardless of whether it is a main or sub-menu) into a
parameter/value list, the menu numbers are not included on the display.
