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”. ... - Page 18 5. Connect supply pressure to the actuator temporarily. Supply enough supply pressure to the actuator in order to position the actuator clamp at 50% of the total valve stroke. 6. Insert connection pin into the feedback lever. The pin should be inserted when the actuator clamp is at 50% of the total valve stroke.

5. After setting fork lever position, assemble lock nuts which are located on the bottom of the fork lever. Ensure to set the height of the upper fork lever between 6~11mm, which is lower than the upper bracket’s height. 6. Attach the positioner to the bracket. Fix the clamping pin on the main shaft’s center of the positioner and insert connection pin into the fork... -

Pipeline should have more than 6mm of inner diameter (10mm outer diameter) to maintain flow rate. 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 –... -
Page 23: Ground
Positioner should be grounded. Please use twisted cable with conductor section are 1.25mm and that is suitable for 600V (complying to the conductor table of NEC Article 310.) The outer diameter of the cable should be between 6.35 ~ 10mm. Use shield wire to protect against electro- magnetic field and noise. -

will be calculated automatically. 2. 5 Point Setting This setting set 5 points (0%, 25%, 50%, 75%, and 100%). This requires more setting, but feedback setting will be more accurate than 2 point setting. 5.4.2 Calibration 1. Supply 4mA input signal to the positioner and check if valve position made to its target position. -
Page 27: Adjustment - Orifice
Adjustment - Orifice If the actuator size is too small relative to the flow rate, positioner can have hunting / oscillation. In order to avoid hunting, the orifice must be inserted. 1. Remove the pilot relay assembly from the positioner. 2. -

6. Maintenance Maintenance on pilot relay valve is recommended to perform at least once a year of with or without operation. When dissembling the pilot relay valve, please be careful not to loose any o- rings or stabilizer spring. Please refer to below instruction and diagram. 1. -
Page 29: Troubleshooting
▶ Actuator only operates by On/Off. (1) Check actuator and positioner's acting type. Air pressure exhausts from YT-1000L's OUT1 port as input signal level increases. Therefore, it is standard to connect to OUT1 port when single actuator is used.
