GENERAL INFORMATION

1.01 Notes, Cautions and Warnings

Throughout this manual, notes, cautions, and warnings are used to highlight important information. These highlights are categorized as follows:
NOTE
An operation, procedure, or background information which requires additional emphasis or is helpful in ef­ficient operation of the system.
CAUTION
A procedure which, if not properly followed, may cause damage to the equipment.
WARNING
A procedure which, if not properly followed, may cause injury to the operator or others in the operating area.

1.02 Important Safety Precautions

• The kinds of fumes and gases from the plasma arc depend on the kind of metal being used, coatings on the metal, and the different processes. You must be very careful when cutting or welding any metals which may contain one or more of the following:
Antimony Chromium Mercury
Arsenic Cobalt Nickel Barium Copper Selenium Beryllium Lead Silver Cadmium Manganese Vanadium
• Always read the Material Safety Data Sheets (MSDS) that should be supplied with the material you are using. These MSDSs will give you the information regarding the kind and amount of fumes and gases that may be dangerous to your health.
• For information on how to test for fumes and gases in your workplace, refer to item 1 in Subsection 1.03, Publications in this manual.
• Use special equipment, such as water or down draft cutting tables, to capture fumes and gases.
• Do not use the plasma torch in an area where combustible or explosive gases or materials are located.
• Phosgene, a toxic gas, is generated from the vapors of chlo­rinated solvents and cleansers. Remove all sources of these vapors.
• This product, when used for welding or cutting, produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code Sec. 25249.5 et seq.)
WARNINGS
OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS TO YOUR HEALTH.
Plasma arc cutting produces intense electric and magnetic emissions that may interfere with the proper function of cardiac pacemakers, hearing aids, or other electronic health equipment. Persons who work near plasma arc cutting applications should consult their medical health professional and the manufacturer of the health equipment to determine whether a hazard exists.
To prevent possible injury, read, understand and follow all warnings, safety precautions and instructions before using the equipment. Call 1-603-298-5711 or your local distributor if you have any questions.
GASES AND FUMES
Gases and fumes produced during the plasma cutting process can be dangerous and hazardous to your health.
• Keep all fumes and gases from the breathing area. Keep your head out of the welding fume plume.
• Use an air-supplied respirator if ventilation is not adequate to remove all fumes and gases.
ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process uses and produces high voltage electrical energy. This electric energy can cause severe or fatal shock to the operator or others in the workplace.
• Never touch any parts that are electrically “live” or “hot.”
• Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the welding circuit.
• Repair or replace all worn or damaged parts.
• Extra care must be taken when the workplace is moist or damp.
• Install and maintain equipment according to NEC code, refer to item 9 in Subsection 1.03, Publications.
• Disconnect power source before performing any service or repairs.
• Read and follow all the instructions in the Operating Manual.
FIRE AND EXPLOSION
Fire and explosion can be caused by hot slag, sparks, or the plasma arc.
• Be sure there is no combustible or flammable material in the workplace. Any material that cannot be removed must be protected.
• Ventilate all flammable or explosive vapors from the work­place.
Manual 0-5100 1-1 GENERAL INFORMATION
SC 3000
• Do not cut or weld on containers that may have held combus­tibles.
• Provide a fire watch when working in an area where fire hazards may exist.
• Hydrogen gas may be formed and trapped under aluminum workpieces when they are cut underwater or while using a water table. DO NOT cut aluminum alloys underwater or on a water table unless the hydrogen gas can be eliminated or dissipated. Trapped hydrogen gas that is ignited will cause an explosion.
NOISE
Noise can cause permanent hearing loss. Plasma arc processes can cause noise levels to exceed safe limits. You must protect your ears from loud noise to prevent permanent loss of hearing.

2.06 Application and System Description

The SC-3000 height control system enables a precise clearance control of plasma and oxyfuel torches on cutting machines.
Using this height control system leads to high quality results when cutting with or without the inuence
of water. The SC-3000 system automatically controls the distance between the plasma torch and the metal sheet.
Initial position finding of the work piece
Before the system starts cutting SC-3000 precisely detects the position of the work piece and nds the pre-selected PIERCE HEIGHT (ignition height). This process is called initial position nding.
When cutting with plasma
• tactile, by softly touching the work piece
Explanation of the system and using the Interface Enclosure
SC3000 Torch Height Control system consists of a Linear Drive (Torch Lifter Station), a Remote
Operator Terminal and an Interface Enclosure plus various cables. The Interface Enclosure contains a 115V/230V to 24VDC power supply, an interface module and a PCB with fuses, relays, LEDs and set up switches.
Inside the SC 3000 Enclosure 9-8145
Power Supply provides 24 VDC to operate the SC 3000. It is switch selectable for either 115 VAC or 230 VAC 50-60 Hz but failure to put the switch in the correct position can cause failure of the power supply.
Interface Module
Interface Module is the green box next to the PCB. It has 3 rotary switches which allow selecting the Address of the unit, The Baud Rate and the arc voltage input ratio. The Address and Baud Rate are used for communication over the serial Cutbus. For now they should remain at their factory settings.
The Arc voltage may be set to accommodate different divided arc voltage ratios.
