APEX System & Equipment Controllers

Supervisor Systems &
Controllers
The BDF System Control is a distributed control system which uses the 7355X or 7360DDC Micro-controller as a host and individual micro-controller modules for dedicated control tasks. All modules are managed by a system controller microprocessor. Most of the control electronics are housed in a self standing control cabinet located at the end of the load station or adjacent to offset shroud. Satellite modules are located elsewhere in the Furnace system.

Engineered for additional functionality, with a focus on improved In-situ diagnostics and ease of use, the
VCVD Interface IIITM provides a three-fold increase in electrical accuracy in the leak rate measurement
circuit. Combine this with an LCD readout, self-diagnostic capabilities and additional status monitoring
LEDs, the VCVD Interface IIITM takes a major leap forward in VCVD processing.

    o User selectable pre leak check outgas delay
    o Verification of leak rate calibration by self test
    o Full 60 second leak check
    o Front panel accessible set up adjustments
  • Specifications
    o User selected leak rate trip point
    o Range 1-30mTorr
    o Increment 1mTorr
    o Accuracy +/-2 mTorr
    o User Selected outgas delay 0, 30, 60 Seconds
    o Self Test – Integrity of leak check circuit verified over two 60-second test cycles
  • Key Features
    o Improved drift stability and accuracy
    o Elimination of daughter boards
    o Backward compatibility with our VCVD Interface II board
    o LCD display of trip point and vacuum leak information
    o Operational status provided by front panel LEDs
