  • Page 3: Part Ismc Series Basic Type Operation Manual

    SMC series could be electrically remotely controlled (in the control room) and could also controlled by control buttons on site so as to be operated locally. SMC series’ manual operation mechanism realize local manual operation against valve.
  • Page 4 worm and worm gear and various motor gears and worm shaft gears combination, so that can get wider output speed range.
  • Page 5 4.3 Driving tubular shaft: it is the electric actuator’s power take-off component, including three types which are 2-PC, 1-PC and jaw type. For its structure, refer to Fig.10 to Fig.12. 2-PC driving tubular shaft has a inside valve stem nut and electric actuator bears valve’s axial force. actuato uato Generally, valve stem’s inner thread is processed by user.
  • Page 6 The stroke control movement of SMC-04~2 starts from low-speed shaft(driving tubular shaft). The limit control movement of SMC-3~5 starts from high-speed shaft(worm gear shaft). Limit control mechanism of SMC series is also called “gear limit switch” (herein after referred as G·L·SW).
  • Page 7 For its structure, refer to Fig.16. It can provide two kinds of contact types which are 4R-2C and 4R-4C. 4R-2C type has 8 self-cleaning, large capacity, swiveling contact switches. 4R-4C has 16 this kind of switches. According to control modes, it shall be chose by user when places orders. Each row of the swiveling contact on the G·L·SW’s position could be arranged freely.
  • Page 8 4.8 Position indicator mechanism: it is used to show valve’s position. It is also called MDPI. Two functions: ow valve’s position. It is a w valve’s position. It i pointer-dial scale type, indicating valve position on site; potentiometer makes feedback of valve position to n on site;...
  • Page 9 It is necessary to fill it with oil before putting it into operation. 7. Electric control principle diagram and electric wiring. Because the electric control principle of SMC series electric actuators are in wide range, the electric control...
  • Page 10 principle diagram which used in practice behind the instruction as an attachment. The terminal contrast table, electric element data table are on the Basic electric control principle diagram. Procedure and precaution for wiring: 7.1 Confirm that power supply voltage is identical with motor voltage shown in the name plate. 7.2 For actuators SMC-04, 03, 00, 0, 1, 2, without field push button lamp box, before wiring, remove the G.L.SW cover (the cover with indicator window), the G.L.SW upper and front terminal plates are visible.
  • Page 11 initial adjusting of the close position so that the adjusting would be more reliable for some multi-turn valve. The certain allowance is dependent on the valve operating experiences of customer). b. Now observe the rotor switch 8A-8B for controlling motor power, the Fig. 17 shows No. (8) switch will occur two cases: 1.
  • Page 12 Following is the procedure of “close direction” exact adjusting as an example.(including two cases) a. When the valve close position is not reached (after power-operated), properly actuate the valve manually to reach the close position from the initially adjusted position. Screw out “Adjusting screw” No.5 to make it internal gears disengaged.
  • Page 13 dispatch. The set value is slightly greater than or equal to the maximum torque (MV max) needed for opening and closing the valve. The user need not adjust it. 10.1 In case that “Torque positioning method” is used, if the valve can not be hermetically closed after T.SW acts, and there is certain distance between the indicator and the limit plate, you may adjust the indicator toward the limit plate to increase value MK.
