Water-based CPCs Update

outline
Outline
  • Water-based CPC Improvements
    • Hardware Upgrades
    • Firmware Upgrades
  • Water-based CPC Field Support Documents
    • Quick Guides
    • Recommended Operating Procedures
    • Troubleshooting Guides
water cpc improvements
Water CPC Improvements
  • Model 3781 & 3786
    • update all instruments in the field
    • flow orifice and filter kits for field upgrade
  • Model 3785 (& 3782)
    • update new units and units in for service or repair
    • kits available upon request
  • All other improvements will be included (for no additional charge at annual service and calibration (including hardware for water trap sensor)
  • Customers can upgrade firmware in the field if they choose
3786 upgrades
3786 Upgrades
  • Replace sheath damper and purge orifice with screen less orifices
  • Add 43mm screen purge filter
  • Replace the small area 73mm screen upstream of the total flow

control orifice with a large area 43mm screen

  • Install canister filters upstream of the sheath flow control orifice
  • Add a check for sheath pump and total pump drive to the

firmware. Indicate clog on status screen

  • September 2006: upstream sheath filter was changed from small

area 73mm to large area 43mm

Field Upgrade Kits Available

3781 upgrades
3781 Upgrades
  • Replace the transport, damper and flow control orifices with screen less orifices
  • Replace inlet screen (originally 25μm mesh) with 100um mesh screen
  • Install canister filter upstream of the transport orifice
  • September 2007: upstream sheath filter was changed from small area

73μm to large area 43μm

Upgraded ~20 beta customers in December 2007: Significantly reduced failures in the field (previously failures typically occurred after 8 – 10 days of operation)  Field upgrade installed base February 2008

3785 3782 upgrades
3785 (& 3782) Upgrades
  • Replace filtered purge orifice with an unfiltered orifice and a separate large area 43μm screen filter
  • Replace the small area 73μm screen upstream of the flow control orifice with a large area 43μm screen
  • Add a check for max’d total pump drive to the firmware. Indicate clog on status screen
wcpc firmware upgrade 3782 5 6 version 2 52 1 17 08
WCPC Firmware Upgrade3782/5/6 Version 2.52 (1/17/08)
  • Water Trap Sensor: Added reservoir sensor code to allow sensing of water in the trap (sensor hardware is installed during annual maintenance and calibration)
  • Analog Output: added analog output of concentration (Log-scale 0 to 7V (0 = 1 particle, 1 = 10 particles, 2 = 100 particles, etc.)
  • Recycle Timing: Changed recycle timing to be based on 10 min rather than one hour
  • Clog Indicator: Added clog indicator on status display (“Check sheath damper orifice”) if sheath pump drive is at maximum
  • ‘Over Condition’: Changed ‘over’ condition on 3786 to be displayed on concentrations over 100,000 part/cm3
wcpc continual improvement
WCPC Continual Improvement
  • WCPC Checkout
  • - 100hr run on every new instrument
  • Recommended Operating Procedures
  • 3. Quick Guides
    • - ‘cheat sheets’ that highlight some critical procedures
    • - sent with all new instruments
  • 3781, 3785 & 3786 Troubleshooting guides
    • - problem description with decision tree and pictures
    • - will be added to manuals
