Air Supply - GYS CUTTER 70 CT Manual De Instrucciones

POWER SUPPLY / POWER UP
• This machine is delivered with a 5 pin three-phase plug (3P+N+PE) 400V 16A type EN 60309-1. It is powered by a 400V (50 - 60 Hz) three phased
earthed power supply. This machine must only be used with a three phase electricity supply system with four wires and one earthed neutral.
The absorbed effective current (I1eff) is displayed on the machine, for optimal use. Check that the power supply and its protection (fuse and/or
circuit breaker) are compatible with the current needed by the machine. In some countries, it may be necessary to change the plug to allow the use
at maximum settings. The user has to make sure that the plug can be reached.
• The machine is designed to work on a 400V +/- 15% power supply. If the input voltage is below 340Veff or above 460Veff, the machine goes into
protection and the screen displays an error code.
• Power up the machine by setting the main on / off switch (8 - FIG 1) to I position, and stop it by setting it on the 0 position.
Warning! Never disconnect the power supply while the machine is charging.
CONNECTION TO A GENERATOR
The machine can work with generators as long as the auxiliary power matches these requirements:
- The voltage must be AC, always superior to 400Vac ±15%, and the peak voltage below 700V,
- The frequency must be between 50 and 60 Hz.
It is imperative to check these requirements, as many generators generate high voltage peaks that can damage these machines.
USE OF EXTENSION LEADS
All extension leads must have an adequate size and section, relative to the voltage of the machine.
Use an extension lead that complies with national safety regulations.

AIR SUPPLY

The air supply can come from a compressor or high-pressure bottles. A high-pressure manometer must be used on any type of air supply and must be
able to transport the gas to the plasma cutter. These machines come with an integrated air filter (5μm), but an extra filtering system can be necessary
depending on the quality of the air supply (optional impurities filter, ref. 039728).
If the supplied air is of low quality, the cutting speed is reduced, the cutting quality deteriorates, the maximum cutting capacity
decreases and the life cycle of the consumables is reduced.
For best performance, the compressed air must comply with the standard ISO8573-1, class 1.2.2. The maximum steam point must be - 40 °C.
The maximum quantity of oil (aerosol, liquid and steam) must be 0.1 mg/m3.
The recommended input pressure during air circulation is 5 to 9 bars with a minimum debit of 305 L/min.

Connect the gas supply to the power source using an inert gas pipe with
an internal diameter of 9.5 mm and a quick release connector.
4 mm²
The pressure must not exceed 9 bars, or the filter tank
could explode.
