Setting DI Parameters
You can set parameters for DI ports over the WebUI.
- When a valid level is delivered into a DI port, an alarm is generated. You can set the alarm name and severity.
- A DI port shuts down the inverter using OVGR signals.
The SmartLogger provides eight DI ports, that is, DI1 (GND1) to DI4 (GND1) and DI1 (GND2) to DI4 (GND2). For the connection method, see Connecting the SmartLogger to a Ripple Control Receiver.

- To enable the DI port function, set Activation Status to Activated, and set Alarm Generation, Trigger Shutdown, Trigger Startup to Enable.
- When Dry Contact Status is set to Close, the SmartLogger sends a shutdown or alarm command to the inverter if the external input dry contact is closed. It sends a start command to the inverter if the external input dry contact is open.
- When Dry Contact Status is set to Open, the SmartLogger sends a shutdown or alarm command to the inverter if the external input dry contact is open. It sends a start command to the inverter if the external input dry contact is closed.
- Startup delay: specifies the time for the SmartLogger to send a start command to the inverter.
When using multiple DI ports, ensure that the shutdown signal of each port and OVGR shutdown in Dry contact remote shutdown have recovered. The SmartLogger then sends a start command to the inverter.
Alarm Name is set to DI X (GND X) custom alarm by default on the SmartLogger WebUI and LCD, which can be changed by the user. If Alarm Name has been changed by the user, the new name is displayed on the WebUI but the default name is displayed on the LCD.
