Setting Remote Shutdown
Setting Dry Contact Remote Shutdown
Context
The SmartLogger has four DI ports, and the OVGR can connect to any DI port. The SmartLogger shuts down the inverter over OVGR signals.
When setting this function, ensure that the user-defined DI port is not occupied. Otherwise, the setting will fail.
Procedure
- Set dry contact remote shutdown parameters.Figure 6-82 Dry contact remote shutdown
Parameter
Description
Access port Set the parameter to the DI port connected to OVGR signals.
Effective dry contact status The value can be Open or Close.
NOTE:If OVGR shutdown is enabled and this parameter is set to Close, the SmartLogger sends an inverter shutdown command only when the corresponding DI port is in the Close state.
OVGR shutdown Specifies whether to enable shutdown over OVGR.
Cubicle alarm enabling If this parameter is set to Enable, the Abnormal Cubicle alarm is generated when the dry contact signal is effective and the Cubicle is abnormal.
Setting NS Protection Remote Shutdown
Context
- The NS protection function applies to areas complying with the VDE 4105 standard. Choose and set Grid Code to VDE-AR-N-4105 or SWITZERLAND-NA/EEA:2020-LV230.
- The NS protection device is connected to the AI1 port and 12V power output port. The SmartLogger shuts down the inverter over the voltage change detected at the AI1 port. When the NS protection device is disconnected, the AI1 port voltage is 0 V, and the inverter shuts down. When the NS protection device is connected again, the AI1 port voltage is 12 V, and you need to start the inverter manually.Figure 6-83 Networking
Procedure
- Set NS protection remote shutdown parameters.Figure 6-84 NS protection remote shutdown
Parameter
Description
Access port Set the parameter to AI1 port connected to AI signals. The SmartLogger shuts down the inverter over the voltage change detected at the A1 port.
- Set the protocol type of the RS485 communications parameters. Protocol of the COM1 port is set to Modbus by default, and that of the COM2 port should be set to Modbus-Control. Set Baud rate, Parity, Stop bit, Start address, and End address based on the actual situation.
- If only one inverter is connected to the SmartLogger, connect the COM1 port on the SmartLogger to the RS485-1 port on the inverter, and connect the COM2 port on the SmartLogger to the RS485-2 port on the inverter.
- If inverters are cascaded, connect the COM1 port on the SmartLogger to the RS485-1 port on the inverter, and connect the COM2 port on the SmartLogger to the RS485-2 port on the inverter. Connect the RS485-1 and RS485-2 ports on one inverter to the RS485-1 and RS485-2 ports on the other inverter, respectively.
Because there are many types of inverters, the RS485-1 port may be named RS485_1, 485B1, or 485A1. The RS485-2 port may be named RS485_2, 485B2, or 485A2.
