1: Functional Features

The control module uses advanced hybrid integrated circuits, featuring powerful functions; it has non-invasive remote control operation capabilities, allowing parameter adjustment and setting without opening the cover; it supports on-site manual operation and can output contact feedback; it also has self-diagnosis and alarm functions for faults.

Features and Functions of the 3720 Series Intelligent Electric Actuator:

The control module uses advanced hybrid integrated circuits, offering strong functionality.

Non-invasive remote control operation: parameters can be adjusted and set without opening the cover, supporting on-site manual operation and outputting contact feedback, displaying manual/automatic working states.

The control module employs menu settings, making parameter setting and function adjustment simple and convenient.

Input signal setting function: allows selection between analog control (DC4~20mA) or switch control (AC220V) based on working conditions, with independent wiring and no interference, both can output DC4~20mA feedback signals.

Valve position display and fault alarm function have input signal and valve position display capabilities, along with indicators for signal, manual/automatic, forward/reverse action, limit, and fault.

Action time and number of actions memory function.

Calibration function for input signals and feedback signals to improve control accuracy.

Anti-interference function: sets reverse action delay time to avoid reverse impact.

Zero point and travel calibration are convenient and accurate, can be set at any position.

Four state settings for small signals: fully closed, fully open, self-set (full stroke), hold in place.

Electronic limit function: has in-position contact feedback.

Self-diagnosis function for faults: can diagnose fault phenomena, protecting the actuator.

Overload protection function: overload protection time can be set as needed.

Temperature protection function: equipped with a temperature protection switch inside the motor to prevent burnout.

Uses an embedded click structure, with a reasonable overall design, compact mechanism, small size, light weight, and good heat dissipation.

The actuator self-locks after power off.
