TURBO-V 301 RACK CONTROLLER
DESCRIPTION
The controller is available in two versions which differ
only in the factory-set input voltage:
•
Model 969-9437 (220 Vac, 50-60 Hz)
•
Model 969-9537 (120 Vac, 50-60 Hz)
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 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
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.
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.
