New Myers Vacuum AVC-485 Automatic Valve Controllers
More Info on the
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.
Time delay, for sequential automatic valve operations is preset. Settings can be changed to match a customer's requirements.
A clear and bold schematic of a typical system is on the front panel to assist in tracing the function being performed. In the automatic mode, LEDs on the schematic indicate valve status.
The panel meter indicates the station pressure in the chamber and at the foreline or regen line. The sensors are the highly reliable and stable GT-034 thermistor tubes.
Operator-Selectable Phases - Pressing the system stop button closes all vacuum valves except the foreline valve on Diffusion/Turbo pump systems, putting the system in a standby condition. Pressing the system vent button puts the chamber in the standby condition and then opens the chamber vent valve. The vent valve is closed automatically after a preset time to conserve backfill gas.
When switched to the automatic mode, the controller sets the system in a safe operating condition regardless of the position of the manual pushbuttons.
When switched to the manual mode, the controller will not latch in to the manual mode until all manual pushbuttons are in the off (valve closed) position.
These interlocks prevent inadvertent errors by the operator and protect the system during mode changes.
The operator cannot damage the system while it is in the automatic mode. The mode selector switch is tamper-resistant.
