TURBO-V 2000 ICE CONTROLLER
DESCRIPTION
The controller is available in two versions:
•
Model 969-9448 (220 Vac, 50-60 Hz)
•
Model 969-9449 (120 Vac, 50-60 Hz)
The models are provided with a front panel with an LCD
alphanumeric display to
conditions/parameters of the Turbo-V pump and a
keyboard, and a rear
connectors.
The following figure is a picture of the Turbo-V
controllers. The controller is a solid-state frequency
converter which is driven
microcomputer and is composed of:
•
Power transformer
•
Front panel display and keyboard
•
Rear panel with input/output connectors

•
3 PCBs including: power supply analog and
input/output section, microprocessor and digital
section, display and keyboard circuits. The power
supply converts
(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
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).
