TURBO-V 250 CONTROLLER DESCRIPTION
The controller is available in three versions:
•
Model 969-9423 (220 Vac, 50-60 Hz)
•
Model 969-9523 (120 Vac, 50-60 Hz)
•
Model 969-9425 (120 Vac, 50-60 Hz)
The models 969-9423 and 969-9523 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 model 969-9425 has the right panel with pump
connector and hand held terminal connector, and the
left panel with input/output connector, mains socket,
forepump and vent coil output and fan connector.
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
•
PCB including: power supply and 3-phase output,
analog and input/output section, microprocessor
and digital section, display and keyboard circuits.

(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,
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.
The controller can be operated via:
•
Front panel (or the optional hand held terminal)
switches
chip
•
Remote signals via input/output connector
•
RS 232 serial link (option).
