| NO. V-3EFE | Valve No.: V-3EFE | 100% | Current valve opening |
|---|---|---|---|
| I:0.0A | Current actuator current | T:22℃ | Current temperature of drive motor |
| 192.168.4.1 | Hotspot IP (fixed) | 192.168.0.183 | LAN IP after network configuration (depending on user environment) |
| Offline | Not connected to cloud or remote | Analog | Current control mode is analog |
Network Configuration and Control
Built-in WiFi hotspot (can be disabled or hidden), default hotspot: Saide_Valve NO.(V-3EFE)
After connecting to the hotspot, access the IP: 192.168.4.1 via browser, the interface is as follows:
| POT.V | Valve position voltage | ACS.V | Current sensor feedback voltage |
|---|---|---|---|
| Protect: ACTIVE | Valve status: Normal | Cloud: OFFLINE | Remote or cloud offline |
| ANALOG | Control mode: Analog | MANUAL | Control mode: Manual After switching to manual mode, the valve opening can be adjusted via the slider on the web page |
Opening Data Interface
The actuator can store 7 days of opening data, which can be exported and saved here. You can also use the software we provide (valve_monitor_app.exe) to enter the relationship between valve opening and Cv value or valve opening and pressure, and calculate the physical quantity changes in real time:
Network Configuration Settings
Fill in the LAN name and password, click Save and Restart. The device will automatically obtain the LAN IP address and display it on the screen or web page. In this way, there is no need to connect to the device's hotspot later, and the same page can be freely opened through the IP assigned by the LAN.
It is possible to set whether the hotspot WiFi is hidden;
