  • NOTE: Unit is shipped as CCW to open. If this is not correct for your application, see page 4 to reverse the unit.

    1. Mount the motor mechanism, couplings, and vertical shaft as shown on "Operating Mechanism" drawings. Install and adjust the switch units in accordance with the "Switch Installation" instructions. Connect one air switch unit (#1), only, to the motor mechanism and set it to the fully open position using the manual crank handle. The switch should work freely. Check that the levers on the switch and the outboard bearing swing an equal distance on either side of the center when the switch is in the fully open and fully closed position. (However, if the outboard bearing toggled in the open and/or closed positions, this toggled position is an important setting).

    2. Insert fuses (included) per the following fuse schedule.

      TERMINAL BLOCK POSITION 48VDC 125VDC 120VAC
      F1 25AMP 15AMP 15AMP
      F2 25AMP 15AMP 15AMP
      F3 3AMP 3AMP 3AMP

      NOTE: At this time that:
      Limit switch 1 controls a CCW rotation.
      Limit switch 2 controls a CW rotation.
      Limit switch 3 operates red/green indicator lights.

    3. Using the manual crank handle, set the motor mechanism in the "open" position (loosen the locking plates, if necessary) so that the side key on the coupling sleeve enters the "open" position slot when the coupling sleeve is raised. Raise the coupling sleeve and adjust the space between the vertical shaft knuckle and the motor mechanism knuckle in conformance with the coupling drawing. Tighten the clamps at the upper end of the vertical shaft, and the "set screws" snug to the shaft, but do not pierce the shaft with the set screws at this time.

    4. Reconnect by lowering the coupling sleeve. Using the manual crank handle, operate the motor mechanism to check adjustments for the "open" and "close" positions of the air switch. Adjust the coupling clamp at the top of the vertical shaft, and the locking plates so that the key on the coupling sleeve enters the slots on either side, when the air switch has been fully "open" or fully "closed" and the crank has been backed away, just enough to remove the strain from the coupling.

      1. Readjust the "closed" indicator on the coupling to line up with the pointer on the housing when the air switch is in the fully "closed" position.

      2. Readjust the "open" indicator on the coupling to line up with the pointer on the housing when the air switch is in the fully "open" position.

        NOTE: The indicators will then be located somewhat beyond the positions for lifting the coupling sleeve into either slot.

    5. Connect the second air switch unit (#2) per Switch Installation instructions and adjust to work freely and in unison with the first unit (#1). Adjust and lock as instructed above. Connect the third air switch unit (#3) similarly and lock as instructed above.

      To set limit switches, loosen the two set screws of the associated cam and rotate until the limit switch is depressed/released at the desired set point.

      1. Limit switch 1. Using the manual operating crank handle, operate the air switch to its fully CCW position, noting the direction of the auxiliary switch cam rotation. Following the above instructions, adjust cam 1 in the same direction (of rotation) until the cam just depresses limit switch 1.

      2. Limit switch 2. Using the manual operating crank handle, operate the air switch to its fully CW position, noting the direction of the auxiliary switch cam rotation. Following the above instructions, adjust cam 2 in the same direction (of rotation) until the cam just depresses limit switch 2.

      3. To adjust any additional limit switch contacts, follow adjusting instructions as stated in Section a and/or b.

    6. Raise the coupling sleeve and fasten in the disconnect position before connecting the motor mechanism electrically. Operate the motor mechanism electrically to check mechanism adjustments. The motor mechanism should stop at the open and closed position indicators. One-fourth inch (1/4") over travel of the position indicator is satisfactory, since the motor mechanism is operating at a no-load condition.

    7. Reconnect the mechanism by lowering the coupling sleeve and operate the mechanism electrically a few times to check the adjustments.

    8. Connect the remote control wiring (see wiring diagram).
      Three wires from the customer's equipment are required.
      COMMON found on TB1 7
      OPEN found on TB1 6
      CLOSE found on TB1 5

      NOTE: The customer's control input must be disengaged prior to the end of the operation. If not, the unit will continue to attempt to operate. The SF100/SF200 electrically seals in requiring only a short duration (sec 1) of control input.

    9. Should it be necessary to stop the mechanism in case of emergency, electrical power to the motor mechanism can be cut off by activating the Safety Guard in the direction indicated "open." This, however, should not be necessary if the adjustments have been made as instructed. Stopping the mechanism in this manner is generally discouraged! The (optional) stop push-button is designed for this purpose and should be used when supplied. When the motor mechanism is stopped in mid-operation, the "open" or "close" push button, or toggle switch must be used for re-starting.

    10. After all the adjustments have been made and checked

      1. Check to see that all the piercing set screws have been tightened properly.

      2. Check that the stops on the operating pipes limit the travel of the air switch when operated manually.

      3. Tighten down both set screws on the cams.

    LUBRICATION OF THE MECHANISM

    All bearings are packed with Amoco wheel bearing grease. All gears are coated with Graphokote gear lube #677. Under periodic inspection, both side plates of the gearbox can be removed to check that gears and bearings are adequately lubricated.

    REVERSING THE DIRECTION OF ROTATION

    To reverse the direction of rotation (i.e., CW open/CCW close to CCW open/CW close, or the opposite) the following modifications must be made:

    1. The red and black motor leads must be reversed on the M1 contactor terminals 2 and 6 (see wiring diagram).

    2. The "open" and "close" indicators on the motor mechanism knuckle must be reversed.

    3. Interchange the orange and brown wires on ASW-1 and ASW-2.
      Interchange the blue and white wires on ASW-1 and ASW-2.
      Interchange the red and green wires on ASW-3.
