4. Applications in Industrial Automation
The 9907-1198 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.
2、 Function and performance
1. Function
1) The fire linkage controller can receive fire alarm signals from the fire alarm controller and emit fire alarm sound and light signals.
In a non delayed state, it can send a start signal to various controlled devices connected to it within 3 seconds, directly or indirectly control the
controlled device according to the set control logic, and at the same time send a start light indication signal. The fire linkage controller can receive
feedback signals from controlled equipment actions and display the corresponding equipment status.
2) The fire linkage controller can receive alarm signals from related triggering devices such as the pump start button, water flow indicator,
and gas fire extinguishing system start button, display their location, emit alarm sound and light signals, and send the alarm signals to the connected fire alarm controller.
3) The fire linkage controller can complete all control functions and indicate status manually or automatically. In automatic mode,
manual insertion operation takes priority.
4) The fire linkage controller has a direct manual control unit. The direct manual control unit shall have at least six independent manual
control switches, each corresponding to a direct control output. When the direct manual control unit can be used
independently, various working states such as startup and feedback of the controlled equipment can be displayed separately next to
the manual control switch. When the direct manual control unit cannot be used independently, the other working states of the controlled equipment,
except for the startup state, are indicated separately next to the manual control switch or displayed on the shared display of the linkage controller.
5) The fire linkage controller can initiate logical relationships through manual or programmed input, and has
corresponding input “OR” logic and/or “AND” logic programming functions for control outputs.
