Agilent Varian V 250 CU Turbo Pump Controller, 9699523

Agilent Varian V 250 CU Turbo Pump Controller, 9699523

V 250 CU / 9699523 Overview:

The models 969-9423 and 969-9523 are provided with a front panel with an LCD alphanumeric display to indicate the operating conditions/parameters of the Turbo-V pump and a keyboard, and a rear panel with input/output connectors. The model 969-9425 has the right panel with pump connector and hand held terminal connector, and the left panel with input/output connector, mains socket, forepump and vent coil output and fan connector. The following figure is a picture of the Turbo-V controllers. The controller is a solid-state frequency converter which is driven by a single chip microcomputer and is composed of:

• Power transformer
• PCB including: power supply and 3-phase output, analog and input/output section, microprocessor and digital section, display and keyboard circuits.

The power supply converts the single phase (50-60 Hz) AC mains supply into a 3-phase, low voltage, medium frequency output which is required to power the Turbo-V pump. The microcomputer generates the variable output frequency and controls the 3-phase output voltage according to the software and the gas load condition of the pump. Moreover, it manages signals from sensors, input/output connection information to be displayed, and gives outputs for a fully automatic operation. A dedicated non-volatile RAM is used to store pump operating parameters and the input/output programmed information upon failure for a period of 10 years accumulated off time.

• The controller can be operated via:
• Front panel (or the optional hand held terminal) switches
• Remote signals via input/output connector
• RS 232 serial link (option).
