Features and functions 1. LCD equipped outside of product makes to check the positioner condition in the field directly.
11. Tight Shut-Close and Shut-Open can be set voluntarily.
2. It endures severe vibration.
12. PID parameters can easily adjusted in the field without additional communicator.
3. It is operated normally regardless of change of supply pressure during operation.
13. The pressure of Air filter regulator is sent to Actuator directly with using A/M switch.
4. Auto calibration method is very simple.
14. Split range such as 4-12mA, 12-20mA is available.
5. It is easily equipped on small actuator because of its small size.
15. Setting Zero and Span as partial section is available by Hand Calibration function.
6. Air consumption is so small that operating cost in huge plants is decreased.
16. The valve defect is easily checked because the valve can be operated voluntarily.
7. Because it can be used in low voltage (8.5V), there is no limitation in controller.
17. It has IP 66 protection grade. 18. Air filter regulator can be attached with the product with only one linear nipple without extra piping.
8. Variable orifice is applied and so in case of small actuator the hunting is controlled to the optimum condition during operation.
19. Because of Epoxy polyester powder coating, it can be used for long period of time in corrosive air.
9. The adjustment of Valve characteristics (Linear, Quick open, Equal percentage) is available.
20. Because of simple and modulized inner structure, maintenance is very easy.
10. Specific flow control is available with setting 16 point at users' command.

Manual
Auto Adjustment of A/M switch
If this switch is set as auto, supply pressure is transmitted to actuator by the operation of YT-2400 and if it is set as manual, supply pressure of air filter regulator is transmitted to actuator regardless of YT-2400.
Minimum open Adjustment of variable orifice
The actuator volume is too small, hunting can be occurred. In this case, adjust variable orifice with using (-) driver, then hunting is prevented by reducing flow rate of supply pressure transmitting to actuator.
