GENERAL DESCRIPTION

The Turbo-V 81 PCB controller is a microprocessor-
controlled, solid-state, frequency converter with self-
diagnosis and protection features.
The controller drives the Turbo V-81 pump series by
controlling the voltage and current respect to the speed
reached by pump.
It incorporates all the facilities required for the operation
of the Turbo-V 81 pump series: pump start/stop, digital
current and speed control, analog signals for external
indicators.
The power is externally supplied.
All the input/output connections are performed on three
connectors (J2, J3 and J4).
The controller is also designed to be controlled by a
host computer via an RS-232 connection (connector J5,
RS 485 available on request).
TURBO-V 81 PCB 24 VDC CONTROLLER
DESCRIPTION
The controller is a solid-state frequency converter that
is driven by a single chip microcomputer and is
composed of a PCB that includes all the circuitry
necessary for its operation.
The microcomputer generates the variable output
voltage according to the software and the gas load
condition of the pump.
Moreover, it manages
input/output connection information, and gives output
for a fully automatic operation.
signals from sensors,
The controller can be operated via remote signals
through an RS-232 connection.
The controller can be operated in local mode through
suitable switches connected between the input pins of
J4 connector and ground (see section J4 connector for
a detailed description of the input signal present on J4
connector).
