urbo-V 2000HT Controller Description
The controller is available in two versions:
Model 969-9462 (220 Vac, 50-60 Hz)
Model 969-9562 (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 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
Front panel display and keyboard
Rear panel with input/output connectors
Power PCB including: power supply and 3-phase output.
Control PCB including: 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. 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
