1. Introduction General Information for the users Thank you for purchasing Young Tech Co., Ltd products. Each product has been fully inspected after its production to offer you the highest quality and reliable performance. Please read the product manual carefully prior to installing and commission the product. ...
2. Product Description General YT-3300 series Smart Valve Positioner accurately controls valve stroke in response to an input signal of 4-20mA from the controller. Built-in micro-processor optimizes the positioner’s performance and provides unique functions such as Auto-Calibration, PID Control, Alarms, and HART Protocol Communications.
Product Number ** YT-3300 series can be used for direct-mounting application. ** YT-3301 standard cable length is 5 meters. Maximum cable length is 20 meters. YT-3300/3301 series...

3. Installation Safety When installing a positioner, please ensure to read and follow safety instructions. Any input or supply pressures to valve, actuator, and / or to other related devices must be turned off. Use bypass valve or other supportive equipment to avoid entire system “shut down”. ...

3. Attach the positioner with bracket to the actuator yoke – DO NOT TIGHTEN POSITIONER COMPLETELY. 4. Connect positioner’s feedback lever to the actuator clamp. The hole gap on the feedback lever is 6.5mm. The connection pin’s outer diameter should be less than 6.3mm.
9. After installing the positioner, operate the valve from 0% to 100% stroke by using direct air to the actuator (manual position). On both 0% and 100%, the feedback lever should not touch the lever stopper, which is located on the backside of the positioner. If the feedback lever touches the stopper, the positioner should be installed further away from the yoke.
2. Mount YT-3300L onto actuator’s yoke by using 2 bolts. As you mount the positioner, please be careful not to lose o-rings from the air channel. Please ensure that the lever adapter connection has been properly installed onto actuator’s stem before tightly fastened.
Using hexagonal bolts and washer, fasten YT-3300R with the supplied bracket. Do not tighten bolts completely before correct mounting of YT-3300R has been confirmed. Insert YT-3300R’s main shaft into actuator’s stem, and place the bracket align to the actuator’s bolt holes.
The length of pipeline system should not be extremely long. Longer pipeline system may affect flow rate due to the friction inside of the pipeline. Connection – Actuator 4.4.1 Single acting actuator – YT-3300 Singe acting type positioner is set to use OUT1 port. OUT1 port should be connected with supply pressure port from actuator when using single acting type of spring return actuator.
4.4.4 Double acting actuator – YT-3301 Double acting linear (left) and rotary (right) type actuator Connection – Power 4.5.1 Safety When installing in hazardous and explosive gas area, conduit tube or pressure-proof packing union must be used. The compound charging box should be the flameproof type and must be sealed completely.

4. When using inside ground, use 3mm wrench to loosen locking bolts of the terminal box cover. 5. Adjustments Limit Switch Adjustment YT-3300 series can have limit switch option. If user wants to adjust the position, please loosen cam bolts and adjust cam. Mechanical Type Proximity Type...
Auto/Manual Switch (A/M Switch) Auto/Manual Switch allows the positioner to be functioned as by-pass. If switch is set as Auto, the positioner will operate per input signal. If switch is set as Manual, the positioner will send supply pressure directly to the actuator. Variable Orifice Adjustment Positioner can cause hunting with extremely small size of the actuator.
6. Operation Safety Following process will operate valve and actuator. Before proceed with any AUTO Calibration, please separate valve from the entire system, so AUTO Calibration will affect entire valve process. Button Description Positioner has 4 buttons, and they enable to perform various functions. Fig.
6.3.1 Auto Calibration (AUTO CAL) Auto Calibration (AUTO CAL) automatically calibrates the positioner. “AUTO CAL” process takes about 2~3 minutes, and the duration of the process varies upon the size of the actuator. There are 3 types of AUTO CAL. Zero Point End Point KP, KI, KD...
