5.2.5 Select the process by press F3 key and use the arrow F2 key for print out the parameter.
5.2.6 For start up process use UP and down arrow key to select F1and pressF1 key for start up cycle.
5.2.7 Similarly switch ON the Dot matrix printer for print the data.
5.2.8 For charter recorder press Func Key than screen will display print data, after that press CHUP Key twice
for print the charte. Now chart printing will start and press the Record key for recording the chart.
5.2.9 When process will complete than LCD screen display End process.
5.2.10 Now press the Open button for Open the Door from sterile side and unload the Material from autoclave.
5.2.11 After unload the material, push the door close button and press Ask button when sterile side door close
indication will glow.
5.2.12 Now check the general parameter for next cycle operation and fallow 5.2.1 to 5.2.11 points.
5.2.13 Start the Dot matrix Printer attached with the PLC so that it will record the complete operating
cycle Parameters and the temperature throughout the cycle. Preserve the Temperature chart in an
authorized record for each and every cycle operation.
