TURBO-V 300HT CONTROLLER DESCRIPTION

The controller is available in two versions:
•
Model 969-9424 (220 Vac, 50-60 Hz)
•
Model 969-9524 (120 Vac, 50-60 Hz)
The models are provided with a front panel with an LCD
alphanumeric display
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
microcomputer and is composed of:
•
Power transformer
•
Front panel display and keyboard
•
Rear panel with input/output connectors
to indicate the operating
panel with input/output
driven by a single
Turbo-V 300HT controllers
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
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
chip
programmed information.
The controller can be operated via:
•
Front panel switches
•
Remote signals via rear panel connectors
•
RS 232/485/422 serial link (option).
