The external dimensions of the rotary model are approximately 221 × 166.5 × 113.5 mm (L×W×H). Weight: Approximately 2.8 kg. Installation Method The YT-1000R is a rotary positioner, and its installation focuses on the correct setup of the cam and feedback shaft. The main steps are as follows: Install the Positioner: Fix the positioner to the rotary actuator using a bracket, ensuring that the positioner's main shaft is concentric with the actuator's main shaft. Connect the Feedback Shaft: Connect the positioner's feedback shaft to the actuator's main shaft, ensuring a secure and tight connection. Cam Installation: This is a critical step. Choose the cam installation face (DA face or RA face) based on the actuator's direction of motion (clockwise or counterclockwise rotation). DA (Direct Acting): When the input signal increases, the actuator shaft rotates clockwise. RA (Reverse Acting): When the input signal increases, the actuator shaft rotates counterclockwise. Zero Point Calibration: With a 4mA input signal, loosen the cam's locking nut, rotate the cam to align its zero point scale with the bearing contact point, then tighten the nut. Span Adjustment: Input a 20mA signal and check if the actuator has rotated to 90°. If the stroke is too large or too small, make fine adjustments using the span adjustment knob. Repeated Calibration: After span adjustment, recheck the zero point, and repeatedly adjust the zero point and span until both meet the requirements. The positioner comes with mounting plates and accessories that match various types of actuators, making installation and adjustment relatively easy. ️ Measurement Medium Medium Type: The product itself does not directly measure the fluid medium in the pipeline. It receives an electrical signal and uses clean compressed air as the power source (working medium) to drive the rotary pneumatic actuator, thereby indirectly controlling the opening of valves (such as butterfly valves, ball valves). Air Source Requirements: The supplied air must be purified, removing moisture and dust, to maintain stable operation of the positioner.
