① Mount a Remote-transmitter RT-100 to the control valve as shown below
② Connect the feedback lever to the control valve stem at position where the angle between the valve stem and the feedback lever becomes 90° as shown below when the input signal is set to 12mA(50%)
③ Stroke range for the best performance should be 5~80mm and the operating angle of the feedback lever should be maximum 45° to carry out accuracy and linearity perfectly |
 |
 |
 |
|
 |
 |
|
① Mount the multi-type bracket to the actuator as shown below
② Confirm the rotating direction of the actuator for air piping (see catalog and manual for details)
③ Confirm if the feedback lever shaft "A" is placed in the orifice of the fork lever "B" and they are in perfect alignment with a rotary actuator output shaft |

① Push MODE key for more than 5 seconds, and Auto Calibration will start.
② The time required for this process may be different according to the actuator volume, but it generally takes about 2~3 minutes. |
 |
| |
 |
 |
| |
 |
Note that the input signal should be provided for measurement of output signal.
① With a mA loop calibrator Select Measurement mode and connect ＋ to 4 and － to 5
② With a mulitimeter tester(mA)
|
 |
| ZERO / SPAN of position feedback will be automatically set after Auto Calibration . |
| |
 |
 |
|
Note that the alarm limits were already set at the factory to 0 ...10%for AL1(L,H) and 90...100%forAL2(L,H). Please refer to the manual for details. |
