Varian Turbo V 1000 ICE Turbo Pump Controller, EX9699547S009, (V1000ICE, 9699547)

Overview:

The Varian Turbo-V 1000 ICE series controllers are microprocessor-controlled, solid-state, frequency converters with self-diagnostic and self-protection features.

The controllers drive (within ten steps) the Turbo-V 1000 ICE pump during the starting phase by controlling the voltage and current respect to the speed reached by the pump. They incorporate all the facilities required for the automatic operation of the Turbo-V 1000 ICE pump series.

Remote start/stop commands, pump status signals, forepump start/stop commands, interlock control signals (for pressure switch, water flow switch), heater jacket control signals, flow meter control signals and purge valve management signals are provided via auxiliary connectors.

The controller is available in two versions:

• Model 969-9447 (220 Vac, 50-60 Hz)
• Model 969-9547 (120 Vac, 50-60 Hz)

The models 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 controller is a solid-state frequency converter which is driven by a single chip microcomputer and is composed of:

• Power transformer
• Front panel display and keyboard
• Rear panel with input/output connectors
• PCB including: power supply 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. The heater jacket and flow meter are also handled.

An EEPROM internal to the microprocessor is used to store pump operating parameters and the input/output programmed information.

The controller can be operated via:

• Front panel switches
• Remote signals via rear panel connectors
• RS 232/485/422 serial link (option)
