The standard size of bolt is M8 x 1.25P, and other bolt sizes are available. Please contact YTC sales department. 3) Attach YT-2700L (with bracket) to the actuator yoke – DO NOT TIGHTEN COMPLETELY. - Page 11 4) Connect YT-2700L feedback lever to the actuator clamp. The gap on the YT-2700L feedback lever is 6.5mm. The connection bar thickness should be less than 6.3mm. <Figure 3> 5) Connect air filter regulator to the actuator temporarily. Set supply pressure of the regulator in order to position the actuator clamp at 50% of valve stroke.

Note After installing YT-2700L, operate the valve from 0% to 100% stroke by using air filter regulator on the actuator. Both of 0% and 100%, the feedback lever should not touch the lever stopper, which is located on the backside of YT-2700L. <Figure 7> If the feedback lever touches the lever stopper, YT-2700L should be installed further away from the center of the yoke. - Page 13 1) Attach bracketed YT-2700R to the actuator by using hexagon-headed and wrench bolts. Size of the bracket hole is 6mm. When tightening bolts, please use spring washer or similar for firm attachment to the actuator, so YT-2700R will not be affected by vibration or any other impact.

Following process will operate valve and actuator. Before starting Auto Calibration, please separate valve from the entire system, so Auto Calibration will not affect entire valve process. Button Description Run Mode (RUN) After power connection to YT-2700 series, following message will appear on LCD screen within 6 seconds. -
Page 18: Auto Calibration (Auto Cal)
"RUN" indicates that YT-2500 adjusts valve stroke with receiving signals (4~20mA) and "PV" indicates the process value. In RUN mode, the valve stroke continuously changes according to the input signal. There are six types of display message in RUN mode To change display, push <ESC>... -

Page 20: Manual Mode (Manual)
Auto HF Calibration sets all of the parameters, like Auto 2; however, it is used for high friction valve environment Manual Mode (MANUAL) MANUAL MODE is used to move valve stem manually. During MANUAL MODE, YT-2700 moves valve strokes, not by input signal. The movement of the stroke does not affect YT-2700 saved data values, and it just moves valve strokes up/down physically.
