32 Digitizer Introduction: The major IP run steps
Animation from WBT CR30-X “Functional description / IP cycle”

33 Digitizer Introduction: Scan Principle (1)
Laser Diode: - Power max = 45 mW Polygon: - 6 facets - Ball bearings - Run-up period approx. 5 sec. - Follow-up period approx. 10 min. Calibration Board - BOL / EOL Sensor 18 diodes for geometric correction 2 diodes (BOL and EOL)

34 Digitizer Introduction: Scan Principle (2)
Data path from exposure to 16 bit raw image data Digitizer sends raw 16 bit image data to NX. Shading Calibration curve is applied on NX!

35 Digitizer Introduction: Scan Principle (3)
Timings

36 Digitizer Introduction: Scan Principle (4)
Geometric Correction: To correct irregularities in the optical path, the digitizer measures at each boot-up the timings of the laser beam between pin diode 1 and 2, 2 and 3 and so on. As a result a kind of "calibration curve" is created, which corrects possible distortions. Jitter Correction: To correct irregularities in the polygon run, the digitizer measures the timings between the BOL and EOL signal during each scan. Certain irregularities, which may be caused by external vibrations or the polygon ball bearings are smoothed by calculating mean values of several scan lines.

37 Digitizer Introduction: Scan Principle (5)
Synchronization of Polygon, Begin of Scan, Begin of Line and AD Window : When an IP is inserted the polygon starts up. The BOL/EOL sensors measure the position of the polygon mirrors (they even detect each single facet). When the IP arrives for scanning, the sensors of the calibration board detect the IP edge and generate the begin of scan signal (BOS). The begin of line signal (BOL) triggers a timer for switching on the laser beam and the AD window. The length of the AD window and "Laser On" depends on the image plate size.

38 Digitizer Introduction: Stall Detection (1)
Stall detection (= load detection) Motor stall (home/end position) detection without the use of additional sensors Made by evaluation of stepper motor control curve on the motor controller chip Advantage (compared to home/end position detection via light sensors): Monitoring of motor run not only in home and end position, but also between home and end position (except acceleration / deceleration time) Less sensors (costs, reliability) and cabling (costs).

48 Digitizer Introduction: Hardware Modules (8)
Functions of the Blue LED in the Light Collector  Signal correction before scan: AUTOZERO With laser and blue LED switched off, the system measures the output of the PMT. This value is the AUTOZERO value. Parameters: Noise of the PMT electronics; Remaining light  Error message if AUTOZERO value exceeds certain limit (e.g. covers opened)  Signal corrections during scan: AUTOCAL During laser blank time, till the next facet scans a line, the blue LED is switched on to measure the sensitivity of the PMT. By combining the measured values of several lines the sensitivity is automatically adjusted (High Tension at PMT) Blue LED

57 Installation (2) Settings of CR30-X in the configuration screen “Device configuration” of “NX service and configuration tool”

58 Troubleshooting

59 Repair Calibration & Adjustments Spare Parts E-Labels
SW Update/Upgrade

60 Repair: Calibrations and Adjustments
To be done in case .... Shading calibration After replacement of the PMT with light collector After replacement of the optic module Whenever the PMT or light collector have been removed (e.g. for replacing the slow scan module) Details see chapter 3.6, Technical Documentation

61 Repair: Spare Parts Alltogether 34 Spare Parts (Status 07/2006)
Recommended spare part: "Small parts Kit, CM+XYZ" Repairable parts (to be sent back): Optic module Slow scan unit Cassette opener unit (with IP handling board)

62 Repair: E-Labels (1) Following PCBs are equipped with E-Lables:
PMT PMI Board Slow Scan Board IP Handling Board Optic Module PCB E-Label contains module specific data

63 Repair: E-Labels (2) Two exchange scenarios: Examples:
1. Spare part (e.g. Slow scan board) is part of a larger module and requires module specific data: E-Label on Board gets SN 9999 in production This is the trigger for the processing station to copy the module specific data to the E-Label of the board.

64 Repair: E-Labels (3) Two exchange scenarios: Examples:
2. Spare part is an adjusted module (e.g. slow scan unit) which has its own module specific data: E-Label on Board gets SN 2345 in production (2345 is just an example) This the trigger for the processing station to copy the module specific data from the E-Label to the processing station for backup reasons

65 Repair: E-Labels (4) Consequence of the two exchange scenarios:
Following kinds of exchange are not allowed: Do not use a "Slow scan board" or "IP handling board" from another digitizer. Do not use a "Slow scan board" which is originally part of a spare "Slow scan module" to exchange the "Slow Scan board" only. Do not use an "IP handling board" which is part of a "Cassette fixation unit" to replace the "IP handling board" only.

66 Repair: Software Update/Upgrade

67 Maintenance Each 12.000 cycles / once a year
Indicated via message at processing station (can be de-activated: CR30-X Service Client  Maintenance Indicator) No preventive replacements ! Main Tasks Get digitizer status (Infocounter evaluation) Clean digitizer inside Check and clean image plates Check Image quality
