The <strong>Sun</strong>ny Island offers you several options for the control of internal and external processes. For this<br />
purpose, two relays are integrated into the device, to which you can assign functions using the<br />
parameters "241.01 Rly1Op" and "241.02 Rly2Op".<br />
You can find more information on both relays in section 6.4.4 ”Multi-function Relay 1 and 2”<br />
(page 45). The different settings have the following meanings:<br />
Function/Setting Meaning Function description<br />
Off Off Relay remains permanently switched<br />
off (deactivated).<br />
On On Relay remains permanently switched<br />
on (e.g. relay function test during<br />
commissioning)<br />
AutoGn Automatic generator request The generator is automatically<br />
activated due to set criteria (see<br />
section 14.1.5 ”Automatic Generator<br />
Operation” (page 114)).<br />
AutoLodExt Automatic load shedding dependent<br />
on an external source<br />
Automatic connection / disconnection<br />
of loads. Connection occurs if the<br />
device is connected to an external<br />
source (e.g. generator), or if the<br />
Lod1Soc limits are exceeded. See<br />
section 12.1 ”Load Shedding”<br />
(page 92).<br />
AutoLodSoc1 Auto LoadShedding Soc1 Automatic connection / disconnection<br />
of loads. Connection only if Lod1Soc<br />
limits are exceeded. See section<br />
12.1 ”Load Shedding” (page 92).<br />
AutoLodSoc2 Auto LoadShedding Soc2 Automatic load disconnection.<br />
Connection only if Lod2Soc limits are<br />
exceeded. See section 12.1 ”Load<br />
Shedding” (page 92).<br />
Tm1 Timer 1 (time-controlled switching of<br />
relay 1)<br />
Tm2 Timer 2 (time-controlled switching of<br />
relay 2)<br />
Programmable timer (once, daily,<br />
weekly) with duty cycle.<br />
Programmable timer (once, daily,<br />
weekly) with duty cycle.<br />
AptPhs Absorption phase is active Relay switching when battery charge is<br />
in absorption phase.<br />
GnRn Generator active Relay switching when generator is in<br />
operation and connected.<br />
ExtVfOk External voltage and frequency is OK External voltage and frequency are<br />
within the valid range for connection.<br />
