OperationLogging a Fusion JointTurn the unit on by pressing ON/OFF. In a few secondsthe display screen will appear. If this is the start of thejob, press CLEAR until you see screen 000. The screensare numbered in the upper left corner.Use the following function keys to select data units:Press F2 to select a pressure unit (PSI, BAR, or Kg/cm2).Press F3 to select temperature unit (F or C)Press F4 to select date format (month/day/year orday/month/year)Press F5 to select decimal point (. or ,)Select the appropriate language using the numeric keypad.From the Main Menu screen, check the date and time. Ifeither is incorrect, select the System Menu by pressing 3and select SET CLOCK from the menu. Follow theinstructions on the screen to set the date and time. PressENTER to return to the Main Menu.From the Main Menu select LOG DATA.Follow the instructions on the screen to enter the machineand job setup data.PH01180B-6-10-97TX01367-5-19-97Unlisted MachinesA list of machines are programmed into theDataLogger TM for selection. If your machine is not onthe list, you may enter the name of the machine. Toenter a machine, scroll to UNLISTED from the SelectMachine menu and press enter. Enter the machinedescription or name using numeric keys or arrow keys.This is an optional field. If you do not wish to enter aname, press - and YES/ENTR to enter a blank for themachine name.TX01368-5-19-97Piston AreaPiston area is required to determine recommendedgauge pressures. Machines listed in the DataLogger TMSelect Machine menu have piston area values assignedto them. If an unlisted machine is selected, the pistonarea must be entered to calculate gauge pressure.However, pressure calculation is not mandatory. Leavingthe piston area and the piston area unit entries blank,skips all the prompts for interfacial pressure entries.To enter piston area, type in the piston area value indesired units, then select the units in the next screen.TX01369-5-19-97PH01181-6-10-97PH01182-6-10-975 – 1
OperationCalculate Recommended GaugePressuresA total of six interfacial pressures can be entered; twoheat pressures, two soak pressures and two fusepressures. To skip a pressure, simply pressYES/ENTR. An interfacial pressure that is skipped willnot be displayed or printed out. Entering zero (0)pressure is not the same as skipping a pressure. Zero(0) pressure is a valid entry, and the resultingrecommended pressure is the sum of the calculatedpressure, which is 0, and the drag pressure enteredlater on.PH01183-6-10-97TX01370-5-19-97Measuring DragUse the fusion machine controls to measure dragusing the following procedure.Move the carriage so that the inner jaws areapproximately 3" apart.Shift the carriage control valve to the middle (neutral)position.Select the heating mode, and adjust the middlepressure reducing valve to its lowest pressure byturning the valve counterclockwise.Shift the carriage control valve to the left.Gradually increase the pressure by turning the valveclockwise. <strong>Inc</strong>rease the pressure until the carriagemoves.Quickly reduce the heating pressure valve clockwiseuntil the carriage is just barely moving.Record this drag pressure.To read the drag pressure you can use either thepressure gauge on the fusion machine or the pressuredisplay on the screen. After measuring drag, enter thedrag pressure using the DataLogger TM keyboard. If youdo not enter a drag pressure value, the defaultpressure of 30psi will be used.The DataLogger TM records actual hydraulic cylinderpressure. When you are analyzing the pressure profilerecorded by the DataLogger TM you must subtract thedrag pressure from the recorded pressure to get theactual fusion pressure.PH01184-6-10-97TX01371-5-19-975 – 2
