Dry contact remote shutdown
You can remotely shut down dry contacts on the WebUI.
The SmartLogger provides eight DI ports, that is, DI1
(GND1) to DI4 (GND1) and DI1 (GND2) to DI4 (GND2). The OVGR can be
connected to any DI port, as shown in Figure 7-57.
Figure 7-58 shows the DI ports
of the SmartLogger.
Table 7-14 describes the DI ports.
Before setting the function of remote
shutdown over dry contacts in the following method, ensure that Dry contact remote control is not set in Power Grid Scheduling.
On the Settings tab page, select Dry
Contact Remote Shut and set relevant parameters, as shown
in Figure 7-59. Because of permission restriction, log

- The OVGR sends dry contact signals and can be connected to any DI port of the SmartLogger. Set related parameters based on the actual connection between the OVGR and the SmartLogger. Otherwise, the dry contact remote shutdown function cannot be implemented.
- Set Connection port based on the actual connection between the OVGR and the SmartLogger.
- Effective dry contact status can be set to Close or Open. If OVGR Shutdown Setting is set to Enable and Effective dry contact status is set to Close, the SmartLogger sends the inverter remote shutdown command only when the DI port specified by connection port is closed.
- OVGR Shutdown Setting can be set to Enable or Disable. Set OVGR Shutdown Setting as required.
- Cubicle alarm enabling can be set to Enable or Disable. If Cubicle alarm enabling is set to Enable, if the dry contact signal is effective and the Cubicle is abnormal, an alarm indicating abnormal Cubicle is generated.
