Selection Suggestions
- For the speed control scenarios of generator sets, marine main engines, and gas turbines in harsh environments such as oil and gas fields and marine engineering, WOODWARD 8273-1017 is preferred for its high control accuracy, strong anti-interference performance, and explosion-proof characteristics.
- When selecting, it is necessary to match the corresponding speed sensor type (magnetic pickup or Hall effect) according to the engine model, and configure the relay output function according to the fault protection requirements.
- For applications in hazardous areas, it is necessary to confirm that the module meets the local explosion-proof certification standards, and cooperate with explosion-proof junction boxes and wiring during installation.
Precautions
- When installing WOODWARD 8273-1017, wear an anti-static wristband to prevent static electricity from damaging the internal circuit board; ensure that the wiring of the speed sensor is shielded to avoid signal interference caused by electromagnetic radiation.
- Parameter configuration must be carried out in accordance with the WOODWARD official manual. The PID parameters should be adjusted according to the engine load characteristics, and it is prohibited to modify the parameters without authorization to avoid equipment failure.
- During long-term operation, regularly check the connection tightness of the power supply and signal lines to prevent poor contact caused by vibration; regularly back up the configuration parameters to avoid data loss due to module damage.
- In marine and coastal applications, it is necessary to perform regular anti-corrosion treatment on the module backplane and wiring terminals to prevent corrosion caused by salt spray.
