General Description

The TwisTorr 74 FS PCB controller is a microprocessor-controlled,
solid-state, frequency converter with self-diagnosis and protection
features.

TwisTorr 74 FS PCB 24 Vdc Controller Description

The controller 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 signals from sensors, input/output connection
information, and gives output for a fully automatic operation. 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).
