HySpeed HT2000
Instruction Manual

Introduction
The HT2000, and all Hypertherm plasma systems, undergo rigorous testing prior to shipment and should
require little maintenance if proper installation and operation procedures as outlined in this manual are
followed.
After a routine maintenance section, a system initialization sequence of events flowchart is presented.
Following the flowchart, an initial checks procedure is then given, followed by a troubleshooting guide to aid in
servicing the system, a troubleshooting guide for the STATUS indicators and a chopper checkout procedure.
The microcontroller error code listing has also been included as a diagnostic tool. A gas schematic, timing
diagram and a complete wiring diagram are also available in
Section 10 Wiring Diagrams
.
It is assumed that the service personnel performing the troubleshooting testing are high-level
electronic service technicians that have worked with high voltage electro-mechanical systems
.
Knowledge of final isolation troubleshooting techniques is also assumed.
In addition to being technically qualified, maintenance personnel must perform all testing with safety
in mind. Refer to the Safety section for operating precautions and warning formats.
If you need additional assistance or need to order parts, call our Customer Service or Technical Service
Group at 1-800-643-9878.
WARNING
SHOCK HAZARD: The large electrolytic capacitor(s) (blue-cased cylinder(s)) store large
amounts of energy in the form of electric voltage. Even if the power is off, dangerous voltages
exist at the capacitor terminals, on the chopper, and the diode heatsinks. Never discharge the
capacitor(s) with a screwdriver or other implement…explosion, property damage and/or
personal injury will result. Wait at least five minutes after turning the power supply off before
touching the chopper or the capacitor(s).
