Ing for the SAi worth must coincide with the valid pattern (see Table 6) If not Step 4.STEP 4. Checking deviations of SAi sensors: If SAi, (SAi,VN – |dmin |, SAi,VN |dmax |) No decisions. If SAi, (SAi,VN – |dmin |, SAi,VN |dmax |) Assessment of / elements linked with SAi sensor Step 5 (15) (16)exactly where dmax and dmin will be the maximum and minimum deviations permitted in the measurements from the “i” sensors. STEP 5. The trend is assessed by analysing the mean and normal deviation of your final 1000 cumulative measurements in the SAi value of sensor “i”, whose value is aside from zero.EP=SAi(10-1000) =EP=SAi-EP(17)Table 6.

The result is studied on the encoder scale. Thus, the outcome is obtained inside the quantity of cycles missing for the measurement of a sensor to go beyond its limits. NCTFSAi will be the number of cycles to failure indicated by the SAi sensor. STEP 6. Choice taking. Once the study from the trend from the SAi sensor values within the encoder position has been completed, the relationship between the encoder position scale as well as the time is defined. In this case (see beginning of Section 2): 1 perform cycle 1.000 encoder positions from 0 to 999 = 4 s MTTFSAi = NCTFSAi TC (20)Expression (20) can calculate the amount of cycles which will be performed using the sensor values within their maximum and minimum thresholds. The DBT method and also the encoder assessment scale in the maintenance management with the multi-stage thermoforming machine makes it feasible to ascertain:Deviations in the measurements of the “j” sensors, whose partnership is established together with the “i” items by Table four; Irrespective of whether the evolution of any on the “z” actuator activation/deactivation commands is appropriately coordinated and is proceeding based on the typical pattern; If any in the measurements from the “j” sensors conform to the encoder position; If any on the measurements in the “j” sensors conform for the activation pattern on the “z” actuators at every single encoder position; Irrespective of whether the absolute encoder is giving the shaft position information properly; Regardless of whether the course of action handle, PLC, is executing the commands correctly in accordance with the encoder position. It also tends to make it GYKI 52466 site probable to: Take early choices on machine elements and prevent unwanted faults by assessing the.
