TURBO-V 70 CONTROLLER DESCRIPTION

The controller, factory set for 120 Vac, 50-60 Hz input
voltage, is a solid-state frequency converter which is
driven by a single chip microcomputer and is
composed of:
− Power transformer
− Left panel with input/output connector
− Right panel with pump connector and hand-held
terminal connector
− PCB including: power supply and 3-phase output,
analog and input/output section, microprocessor
and digital section, display and keyboard circuits
− PCB external input/output interface
− 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.

TECHNICAL INFORMATION

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 on
the hand-held terminal, 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 by remote signals via
the left panel connector
monitore/reprogrammed using the optional hand-held
terminal via the right panel connector.
