1. Overview
Built on the LU-607M smart position-proportion controller (valve position control), the LU-907M smart position-proportion controller (valve position control) further improves noise immunity and overall performance through a modular structure, EMI suppression, and other technologies.
The LU-907M smart position-proportion controller (valve position control) is mainly used for kiln temperature control. It can eliminate the servo amplifier and directly drive the actuator, and is widely used in ceramics, glass, and other industries. The LU-907M incorporates advanced Italian instrument technology; it can work both with a valve position feedback signal and without the cumbersome feedback signal wiring. The LU-907M provides hard manual operation and bumpless manual/automatic switching; the minimum and maximum valve positions can be freely set to limit the valve position, and it is compatible with various input signals. A bar graph displays the valve position. The LU-907M provides a valve position dead band, control dead band, and jog function, with the dead band range freely settable.
