The following table provides information as to the reasons why the generator is being
requested. One of the following six letters will appear in the display:
The generator status and the reason for the request are shown (alternating) in the
"Generator status" in the display.
If the generator has been manually set to "Stop" then no generator status information
is shown in the display. The field remains empty.
Display Description
B(attery)
The generator has been requested as a result of the battery
management system.
H(eat)
The generator has been started as a result of a temperature
dependent request.
L(oad)
The generator has been started as a result of a load dependent
request.
R(emote)
The generator was started for one of the following reasons:
• The user directly started the generator.
• The user switched the (optional) GenMan switch to "ON".
• The GenMan automatically started the generator due to a too
low starter battery voltage.
• The Sunny Island 3324/4248 automatically switches to an
external voltage source (displayed in backup systems, as long
as the public grid is present).
In all three situations the Sunny Island 3324/4248 CANNOT start
or stop the generator but may charge the batteries if required.
S(tart)
The generator is requested by the user manually setting the
generator request in the Sunny Island 3324/4248 from "Auto" to
"Start". The generator is then NO LONGER controlled or switched
off by the Sunny Island 3324/4248.
T(ime)
The generator was started for one hour using the "Run1h" setting
in the Sunny Island 3324/4248. Once this time has passed, the
Sunny Island 3324/4248 automatically switches off the
generator.
If (e.g.) the display changes every 2 seconds from "*" to "B" then this means
that the generator voltage and frequency lie within the specified limits and that
the generator was requested by the battery management system.
