Relays SMA Solar Technology AG 15 Relays The Sunny Island offers you several options for the control of internal and external processes. For this purpose, two relays are integrated into the device, to which you can assign functions using the parameters "241.01 Rly1Op" and "241.02 Rly2Op". You can find more information on both relays in section 6.4.4 ”Multi-function Relay 1 and 2” (page 45). The different settings have the following meanings: Function/Setting Meaning Function description Off Off Relay remains permanently switched off (deactivated). On On Relay remains permanently switched on (e.g. relay function test during commissioning) AutoGn Automatic generator request The generator is automatically activated due to set criteria (see section 14.1.5 ”Automatic Generator Operation” (page 114)). AutoLodExt Automatic load shedding dependent on an external source Automatic connection / disconnection of loads. Connection occurs if the device is connected to an external source (e.g. generator), or if the Lod1Soc limits are exceeded. See section 12.1 ”Load Shedding” (page 92). AutoLodSoc1 Auto LoadShedding Soc1 Automatic connection / disconnection of loads. Connection only if Lod1Soc limits are exceeded. See section 12.1 ”Load Shedding” (page 92). AutoLodSoc2 Auto LoadShedding Soc2 Automatic load disconnection. Connection only if Lod2Soc limits are exceeded. See section 12.1 ”Load Shedding” (page 92). Tm1 Timer 1 (time-controlled switching of relay 1) Tm2 Timer 2 (time-controlled switching of relay 2) Programmable timer (once, daily, weekly) with duty cycle. Programmable timer (once, daily, weekly) with duty cycle. AptPhs Absorption phase is active Relay switching when battery charge is in absorption phase. GnRn Generator active Relay switching when generator is in operation and connected. ExtVfOk External voltage and frequency is OK External voltage and frequency are within the valid range for connection. 130 SI5048-TB-TEN110340 Technical Description
SMA Solar Technology AG Relays Function/Setting Meaning Function description GdOn Power distribution grid Relay switching when power distribution grid is available and connected. Error Error Sunny Island has a fault; in case of fault, contact is open (relay is deactivated). Warn Warning The Sunny Island has warning pending. Run Run Sunny Island is in operation, contact is closed (relay is activated) if the device is running in inverter operation. BatFan Battery fan Relay is used for automatic battery room ventilation (switching the fan). AcdCir Acid circulation Relay is used for automatic acid circulation (switching the electrolyte pump). MccBatFan Multicluster battery fan Relay is used for automatic battery room ventilation (switching the fan). MccAutoLod Multicluster auto loadshedding Automatic connection/disconnection of loads due to an extension cluster in the Multicluster system. CHPReq CHP plant request Request of the CHP plant through the CHP plant control CHPAdd Request additional CHP plant Request of additional CHP plant through the CHP plant control SiComRemote Remote control via SI Com module Currently unavailable Overload Overload When using the Sunny Island's output limitation (temperature-dependent), the relay opens.
