Users can read the data clearly at a glance. The display supports both Chinese and English modes. Users can switch them freely based on personal habits and regional requirements. It delivers friendly and intuitive human‑machine interaction. It also shows parameter setting prompts, operation steps and alarm messages. These help users finish calibration, commissioning and troubleshooting quickly. The dot‑matrix LCD display improves convenience in daily operation and monitoring. It also provides important information that helps users detect abnormalities in time and ensure system stability.

Non-intrusive Design

In addition, the Multi-turn Frequent Regulating Type Actuator BD45-C6 adopts a non-intrusive design concept, enabling safe, convenient and maintenance-free valve operation and parameter configuration. All operating functions can be completed through external magnetic control knobs or infrared setting devices, including parameter setting, status query, calibration adjustment and function switching. There is no need to open the electrical enclosure or touch any internal components during operation, which effectively avoids potential risks such as electric shock, short circuit or misoperation, and makes on-site operation simpler and more secure. This non-intrusive structure completely blocks the intrusion of dust, moisture, oil mist and corrosive gases commonly found in industrial sites, effectively protecting the core control board and precision electronic components from damage, and greatly improving the overall sealing performance and service life of the actuator. It integrates Hall sensors and non-contact signal transmission technology, delivering excellent stability and strong anti-interference performance without signal drift or mechanical wear. This design fully meets the high-protection requirements of heavy-duty industrial equipment, significantly reduces on-site maintenance workload, and effectively enhances the safety and operational reliability of the entire actuator system.
