Smart Positioner SP740 Series ⓐ Check a valve's full stroke. ⓑ Connection bar should be consisted with feed back lever's value and full stroke value's equal point . ⓒ If positioner lever and actuator connection bar has not consistent , move and adjust positioner bracket or connection bar.
Smart Positioner SP740 Series 3.4 Rotary positioner Installation Rotary positioner is used for 90 ˚ rotating valve. There are fork lever type and namur type ⑥ NAMUR TYPE ⑤ Fig3-6 Fig 3-7 SP740 Fork lever type SP740 Namur type 3.4.1 Bracket Set assembly for Rotary Positioner Installation ①...
Smart Positioner SP740 Series 3.4.2 Rotary Positioner Installation Step ① Connect upper/lower bracket assemblies onto an actutor with bolts. Note the positioner manufacturer does not supply bolts to fix an actuator. Actuator Lower/upper bracket Clockwise / counterclockwise ② With an actuator's initial start point of 0%, install the fork lever as seen in figure according to the rotation direction of stem.
Smart Positioner SP740 Series 4. Connection - Air 4.1 Supply Pressure Conditions Caution ☞ Make sure that air filter regulator should be installed on the front of positioner. ☞ Supplying air should not be mixed with oil, moisture or impurities.
Smart Positioner SP740 Series 5. Connection - Power 5.1 Safety Warning ☞ Please check whether power is disconnected before connecting terminals. ☞ Supply the lower than described currenct and votlage ☞ Do not install cable on near equipments incurred by noise such as high capacity transformer or motor.
Smart Positioner SP740 Series 5.4 Instrinsic safety's parts terminal Connection ☞ Make sure that instrinsic safety wire must be separated with general wire. ☞ Make sure that electrical parameter must be maintained lower than values indicated on explosion proof certificate.

Smart Positioner SP740 Series 8. Auto Calibration & PCB Operation 8.1 Warning Warning Before working auto calibration , make sure that they have not influence on overal process after saparating valve and actuator in system completely. 8.2 Button Description The positioner has four(4) buttons.
Smart Positioner SP740 Series 8.4 Auto Calibration Mode (AUTO CAL) In case of using AUTO CAL function , control position and function necessary in adjustment can be set automatically. 5-10 minutes are required and according to driving size, the requiring time can increased or decreased.
Smart Positioner SP740 Series 8.5 Manual Mode ( MANUAL ) Manual mode is a mode to check if there is no mechanical interference and problem when installing the positioner and valve in the first time. Press the <UP> and <DOWN> button while the air and command signal (4 ~ 20mA DC) are supplied to the positioner and make sure there is no mechanical interference.
Smart Positioner SP740 Series 8.6.2 KP-UP ( KP_UP) In case of upward motion within 0--> 100% , adjust operation velocity until instruction position. It is used when driving facilities are so small or when friction load is too high , the upward velocity is too slow.
Smart Positioner SP740 Series 8.7.1 SV NORM Positioner's SV value can be output with same open value or reverse value. i.e.) In NORM , input 4mA =0% opening . In REV input 4mA = 100% opening <ENTER 5 <ENTER> <ENTER>...
Smart Positioner SP740 Series 8.8 Valve Mode (VALVE) VALVE mode is mode which can be set various function on control valve's operation . 8.8.1 Valve's operation direction setting mode (ACT DA / RA) If Auto Calibration executes , valve's operation direction set into direct action ( DA ) automatically.
Smart valve positioner SP740 Series 8.8.3 User Defining Flow Characterics Curve mode (USER SET) Users can make flow charerics cusrve randomly and use it. Total 10 point can be defined and can be used. In initail time PO (4mA ) is valve stroke (0% ), PI (5.6mA ) is 6.00 % … P10( 20mA ) is 100% as basic setting mode .
Smart valve positioner SP740 Series 8.8.5 Tight Shut Close (TSHT CL) Tight Shut Close indicates the setting position as %. Tight Shut Close value set as 0% basically . When user want to change opening value if rhe instruction value is input below setting % value, the driving position return into 0% immediately.
Smart valve positioner SP740 Series 9. Error and Warning Code While using products , if there is any problems, Error code can be checked in LCD monitior and warning code can be checked in VIEW mode. 9.1 Error code It is indicated when positioner's control is imposssible or any incorrect operation is expected.
Smart valve positioner SP740 Series 9.2 Warning code Control is possible but it indicates when it can be happened abnormal operation or precsion degree can be degraded. Warning Code Warning contents and cause Action ▶ Reduce discharge air pressure ▶ Indicates that FULL OPEN / FULL CLOSE time is shorter than 0.8 second.
