TURBO-V 550 ICE CONTROLLER DESCRIPTION

The controller is available in two versions:
•
Model 969-9434 (220 Vac, 50-60 Hz)
•
Model 969-9534 (120 Vac, 50-60 Hz)
The models are provided with a front panel with an LCD
alphanumeric
conditions/parameters of the Turbo-V pump and a
keyboard,
connectors.
The following figure is a picture of the Turbo-V
controllers. The controller is a solid-state frequency
converter
microcomputer and is composed of:
•
Power transformer
•
Front panel display and keyboard
•
Rear panel with input/output connectors

•
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
operating
frequency and controls the 3-phase output voltage
according to the software and the gas load condition of
input/output
the pump.
Moreover,
input/output connection information to be displayed,
and gives outputs for a fully automatic operation. The
single chip
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) .
