241.01 Rly1Op: Operating mode of the multifunction relay 1
Value
Explanation
Tm2
Timer 2
The Sunny Island controls external processes time-dependently. When the set time
#243 Timer
is reached, the multifunction relay is activated.
ExtPwrDer
Control of additional loads: the Sunny Island controls additional loads in order to put excess
energy to practical use. When excessive energy can be used, the multifunction relay is acti-
vated.
GnRn
Relay is activated when generator is running: When the generator is in operation, the multi-
function relay is activated.
ExtVfOk
Relay is activated when external source is present: When the voltage and frequency of the
external energy source are within the valid range for the connection, the multifunction relay is
activated.
GdOn
Relay is activated when utility grid is present: When the utility grid is connected, the multifunc-
tion relay is activated.
Error
Relay is deactivated during error: When an error message is pending, the multifunction relay
is deactivated.
Warn
Relay is activated during warning: When a warning is pending, the multifunction relay is acti-
vated.
Run
Relay is activated when cluster is running: When the Sunny Island or the cluster is in opera-
tion, the multifunction relay is activated.
BatFan
Relay is activated when battery room fan is running: The Sunny Island controls the battery
room fan for all clusters together. When the battery room is to be ventilated, the multifunction
relay is activated.
AcdCir
Relay is activated when the electrolyte pump is running: The Sunny Island controls the elec-
trolyte pump of the battery. When the electrolyte is to be circulated, the multifunction relay is
activated.
MccBatFan
Relay is activated when battery room fan is running: The Sunny Island controls the battery
room fan for all clusters together. When the battery room is to be ventilated, the multifunction
relay is activated.
MccAutoLod
Load shedding in a multicluster system
When all batteries have reached the upper SOC threshold, the Sunny Island ends load shed-
ding. When the loads are to be shed, the multifunction relay is deactivated.
CHPReq
No function
CHPAdd
No function
SiComRemote
Multifunction relay is controlled via ComSync.
Overload
When the Sunny Island limits its power, the multifunction relay is deactivated.
