TURBO-V 6000 CONTROLLER DESCRIPTION
The controller is available in two versions:
•
Model 969-9491 (220 Vac, 50-60 Hz)
•
Model 969-9591 (120 Vac, 50-60 Hz)
The controllers 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.
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
•
RS 232/422/485 serial link (option) .
