15 Relay
The Sunny Island 5048 provides you with many options to control internal and external
operations. For this purpose, two relays are integrated into the device with which you
can assign functions using the "#261.01 Rly1Op" and "#261.02 Rly2Op" parameters.
Information on the connection of both relays is provided in section 6.4.4 "Multi-function
Relay 1 and 2" (Page 47). The different settings have the following meanings:
Function/
Settings
Meaning
Functional description
Off
relay is permanently switched off
(deactivated)
On
relay is permanently switched on (e.g. relay
function test during commissioning)
AutoGn
Auto Generator
automatic generator connection
AutoLodExt
Auto LoadShedding Extern
automatic load disconnection
load is connected if sufficient battery
charging current flows (by external supplier,
e.g. generator)
AutoLodSoc
Auto LoadShedding Soc
automatic load disconnection
load is only connected if SOC has exceeded
the set value again
Tm1
Timer 1
programmable timer (once, daily, weekly)
with duty cycle
Tm2
Timer 2
programmable timer (once, daily, weekly)
with duty cycle
Apt-Phs
Absorption phase is active
battery charge is in the absorption phase
GnRn
Generator Run
generator is running (generator is
connected)
ExtVfOk
External voltage and frequency is OK
external voltage and frequency are within
the valid range for connection
GdOn
Grid On
external grid is connected
Alm
Alarm
Sunny Island 5048 has a fault, in case of
fault, contact is open (relay is deactivated)
Rn
Run
Sunny Island 5048 is in operation, contact is
closed (relay is activated) if the device is
running in inverter operation
BatFan
Battery Fan
switches the battery room fan on
AcdCir
Acid Circulation
activates the electrolyte pump (acid
circulation)
You can only assign one function to each relay. If the devices are connected in
parallel, the relays of the slaves can also be used. They are set using the master.
