Cvc products inc avc-485 automatic valve controller
The AVC-485 Automatic Valve Controller is designed to permit either manual or fully automatic operation of diffusion, turbo, or cryopumped high vacuum pumping systems.
The AVC-485 is powered from a 115 volt, 2 amp source and will handle the three basic electropneumatic vacuum valves (roughing, foreline, high vacuum) and a solenoid vent valve in any vacuum system. A screw-driver switch determines the operation mode with separate panel light indicators.
* Easily set controls simplify calibrations of trip points of fore-pressure and vacuum chamber pressure circuits
* Internally switchable for use with Diffusion/Turbo Systems or Cryo pump operation
* Relay trip point settings by means of internally mounted potentiometer
* All microprocessor controlled circuitry
* Adjustable 1-15 minute auto vent stop output
* Capable of interlocking with external controls
* Tamper-resistant AUTO/MANUAL mode
* Easy service-all parts are readily accessible
* Low profile cabinet-suitable for bench top or direct rack mounting
A screwdriver-actuated switch is used to select the operating mode. LEDs indicate which mode is activated.
* Manual Mode: This mode is used when performing maintenance or when operating under exceptional conditions. All valve functions are controlled by the operator alone, using the pushbutton switches. Safety interlocks are inoperative.
* Automatic Mode: In this mode, the controller programs the vacuum system through the roughing and high-vacuum phases at the touch of the system start button.
