4. Applications in Industrial Automation
The 8434-246 plays a critical role in industrial automation and power generation environments:
- Steam Turbine Control: Manages startup, speed regulation, and extraction/admission control of steam turbines.
- Power Generation Systems: Used in power plants to regulate turbine-driven generators for stable frequency and load management.
- Compressor and Pump Drive Control: Ensures precise speed control for turbine-driven compressors and pumps.
- Process Industry Applications: Applied in chemical plants, refineries, and other industries requiring precise turbine operation.
- Safety and Protection Functions: Includes overspeed protection, critical speed avoidance, actuator travel limits, and event logging for operational safety.
Time Controller
When the power of the electrical appliance does not exceed 1320W, a 220V AC contactor is required:
1. Connect the fire neutral wire of the air switch to the inlet of the time controller, and then connect another set of fire
neutral wires from the air switch to L1 and L2 of the 220V AC contactor.
2. The output terminals of the time controller are connected to A1 and A2 of the AC contactor, and the neutral wire
of the electrical appliance is connected to T1 and T2 of the AC contactor.
Time Controller
How to adjust the time of the time controller?
1. Turn on your phone”s Bluetooth and GPS, scan the QR code on the switch, and use the mini program to control the layout.
2. Click on the device and enter the password. The initial password is 0000 (password can be changed).
3. Click on the timer settings, set the timer switch time, and click save and send.
Time Controller
Note: The time controller is a networked automatic time calibration system. When the week is selected, click OK (the start and
end week options are the same). When the hour, minute, and second are selected, swipe to complete and click OK.
