Description of the TwisTorr Medium-TMP Rack
Controller
The TwisTorr Medium-TMP Rack controller models are:
X3501-64006 TwisTorr Medium-TMP One Speed rack controller

X3501-64016 TwisTorr Medium-TMP rack controller, for use with

TwisTorr 404, 704, 804 FS turbo pumps, 120-220 V
The model is provided with a front panel with an LCD alphanumeric display to
indicate the operating conditions/parameters of the Turbo pump and a keyboard,
and a rear panel with input/output connectors. The following figure is a picture of
the TwisTorr Medium-TMP Rack Controller.
The controller is a solid-state frequency converter which is driven by a single chip
DSP and is composed of one PCB which include 3-phase output, analog and
input/output section, Digital Signal Processor and digital section.
The controller converts mains voltage supply into a 3-phase, low voltage, medium
frequency output which is required to power the pump. The controller can be
operated by a remote host computer via the serial connection. A Windows-based
software is available. The DSP 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 DSP 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 and RS 485 serial link.
