1. RT6 M45 light tester algorithms Once the HSL RT6 M45 is installed and the control system is powered back up perform the following to set up and tune the HSL RT6 M45 The set up is performed using a PC running the HSLRT6 set up program or the optional Keypad Display See sections 5 or 6 for a description of the HSLRT6 menus and variables and how to use the HSLRT6 program See section 4 for a description of the Keypad commands and menu displays of the HSL RT6 Keypad Display At the initial installation prior to performing the set up steps below verify that the default user variables see section 2 12 1 are set to the values listed HSL RT6 M45 User s Manual SYSTEMS Electronics Group 17 SECTION 2 INSTALLATION 2 12 1 DEFAULT SET UP VARIABLES As shipped the user variables of the PMT section of the M4530 are set to the following defaults PMT Gain PMT Voltage 0 1200V 1101 Gain Calibrate PMT Input Average XXX M4530 PMT Input Sensitivity maf PMT Input Offset 75 to 75 000 PMT Reject Can Threshold 075 Automatic Offset Mode Enabled Y N YES Desired Good Can PMT Value 030 Allowed Good Can Error 002 PMT Gain Calibration Mode Enabled Y N YES Desired Calibrated Leaker Reject PMT value 120 Allowed Calibrated Leaker Reject Error 005 Where XXX of the Gain Calibrate PMT Input Average can be any number This will change when a calibrate cycle is performed 2 12 2 S2. ET MACHINE ZERO Unlike the original encoder the resolver shaft is not mechanically adjusted to zero the timing but instead is electronically adjusted in the PLS section Position the machine with pocket 1 precisely aligned with the PMT this is the machine zero location Set the resolver offset per section 4 11 HSL RT6 Keypad Display Refer to section 5 Windows based setup program reference or section 6 DOS based setup program reference to set the resolver using the setup program Note The M4530 PLS is automatically programmed with the Sync timing CH00 and Marker timing CH01 No other PLS timing channel programming is required by the user The Sync timing goes on at the centerline of PMT tube to pocket alignment and goes off at the centerline in between pockets HSL RT6 M45 User s Manual SYSTEMS Electronics Group 18 SECTION 2 INSTALLATION 2 12 3 VERIFY THE B2F RFI PMT HOUSING OFFSET The C634 A1H Preamp board inside the B2F RFI housing contains an offset potentiometer used to null any offset of both the PMT and amplifier circuitry If this inherent offset of the PMT and amplifier is too great this potentiometer may have to be adjusted to null the offset to zero This is done by running cans through the machine and verifying the value the PMT offset automatically obtains The PMT housing offset only needs to be set at the initial installation or any time the B2F RFI PMT housing is replaced All other offse
3. SECTION 2 INSTALLATION 2 11 3 SY Sdev PROGRAM DEVELOPMENT SOFTWARE INSTALLATION The SYSdev Program Development software is used to perform on line trouble shooting and program modifications to the HSL RT6 M45 If SYSdev was purchased with the HSL RT6 M45 package and is not already installed on the your computer install SYSdev onto the hard drive of your computer following the steps of the SYSdev Program Development manual 2 11 4 APPLICATION PROGRAM INSTALLATION The HSLRT6 application program is a SYSdev based program loaded into the M4530 module and performs the HSL RT6 M45 logic The HSLRT6 program is written in a combination of Ladder logic and High level If the user desires to make program changes or perform on line monitoring of the program execution the files which constitute the HSLRT6 program will have to be loaded onto the hard drive of the PC which is used to support the HSL RT6 The SYSdev Program Development Software will also have to be loaded on the PC To install this program perform the following 1 Install the disk labeled HSL RT6 M45 PROGRAMS into the drive 2 For each of the HSLRT6 directories created in section 2 11 2 copy all the files from the disk to each of these subdirectories 2 12 TUNING THE HSL RT6 M45 The HSL RT6 M45 is shipped from the factory with the PLC program HSLRT6 loaded in the M4530 module PLC section This is the standard program used to implement the standard HSL

6. m observe both the Good Can Data and the Rejected Can Data The PMT Input Average should be within plus or minus 2 of the Desired Good Can PMT Value set in the M4530 Set up Menu normally set to 30 The Up Peak Max and Down Peak Min should be within plus or minus 5 of the PMT Input Average As leaker cans are rejected they will appear in the Last Reject Value through 8th to Last Reject Value stack When the calibrated leakers are run through the machine the reject values of these cans will also appear in this stack If any of the calibrated leakers are not rejected when run through the machine lower the PMT Reject Can Threshold and try again This value can be lowered to within 5 above the Desired Good Can PMT Value If some of the calibrated leakers still are not rejected increase the PMT Gain this can be increased to a maximum of 1200 volts and try again Note Running the gain of the PMT above 1100 volts will shorten the life of the PMT If some of the calibrated leakers are still not rejected verify that the quality of light is adequate both halogen lamps are on and hub of starwheel is polished If the machine seems to be rejecting an excessive amount of cans select the 4 View Can Reject Counts selection from the Main Menu of the HSLRT6 set up program or the Rejects Per Pocket selection of the HSL RT6 DSP display and observe the Per Pocket Rejec
7. t Totals If a particular pocket is rejecting a significantly higher number of cans than the other pockets then that pocket most likely has a bad light seal or some other mechanical problem In general this menu can be used to evaluate the reject performance of the machine HSL RT6 M45 User s Manual SYSTEMS Electronics Group 21
8. t variations due to temperature etc are automatically compensated for with the automatic offset adjustment feature of the M4530 This adjustment simply makes sure the offset potentiometer of the PMT housing is not set outside the normal range of operation Verify the offset as follows 1 Run the machine with cans at normal line speeds and verify that the offset is automatically adjusted until the PMT Input Average is equal to the Desired Good Can PMT Value within plus or minus 2 Up Peak Max and Down Peak Min should also be within plus or minus 5 of the PMT Input Average 2 Ifthe offset exceeds or 250 in an attempt to set the PMT Input Average equal to the Desired Good Can PMT Value the MAINT LED on the M4530 will be illuminated This indicates that the PMT is detecting an excessive amount of light both when the cans are sampled and at the in between pocket measurement Verify that the machine is timed properly per section 2 12 2 and that no light leakage is occurring at any of the PMT seals machine shutter to light seal plate PMT to light seal plate or at the PMT housing itself 3 Ifthe offset is greater then 20 disconnect the 24VDC power that powers the PS2000N1 high voltage power supply and remove the top of the B2F RFI housing side that contains connectors and adjust the potentiometer on the AlH Preamp board first board below connectors Turning the pot clockwise will decrease the o
