1. Regulations, Safety Regulations and Guarantee
1.1. Regulations
The “Mach-Jet” spray gun is in conformity with standard EN50050/2001. A file is open with a notified
body to obtain the standard CE test certificate (Compliance with directive 94/9/CE)
Spray gun marking and CRN 457 control module marking
:
1.2. Safety Regulations
This equipment may be dangerous if it is not used in compliance with the security regulations specified
in this manual.
• The CRN 457 electro-pneumatic control module must never be installed where there is a risk of
explosion.
• The electrostatic paint spraying equipment must only be used by qualified personnel fully informed
of rules no.° 1 to 12 as follows:
1 A warning notice written in a language understood by the operator, summarising safety regulations
nos.° 2 to ° 9, section 1.1 of this manual, must be placed in a clearly visible position close to the
powder-spraying booth.
2 Shoes intended for operator use must be anti-static and comply with the ISO 2251 publication. If
gloves are used, only anti-static gloves or gloves ensuring grounding of the operator may be worn.
3 The floor in the area in which the operator works must be anti-static (ordinary bare concrete floors
are anti-static).
4 Powder spraying must be carried out in front of a ventilated booth designed for the purpose. Start-
up of the CRN 457 must be interlocked with operation of the ventilation system.
5 Skin-contact with or inhalation of products used with this equipment may be dangerous for
personnel (cf. Safety sheets for products used).
6 All conducting structures such as floors, walls of powder-spraying booths, ceilings, barriers, parts
to be painted, powder distribution tank, etc. that are inside or near the work station
and the earth
terminal
on the electro-pneumatic control module
must be electrically connected to the ground
system protecting the electrical power supply.
7 Parts to be painted must have a resistance in relation to the ground system that is less than or
equal to 1 M
Ω

8 Powder-spraying equipment must be maintained regularly according to the manufacturer’s
instructions. Repairs must be carried out in strict compliance with these instructions.
9 Before cleaning the spray gun or carrying out any other work in the spraying area, the high-voltage
power supply must be switched off in such a way that it can not be switched back on by pressing
the spray gun “trigger.”
10 Only SAMES original spare parts guarantee operating safety of the equipment.
11 Ambient temperature must not exceed 40°C.
12 Switch off the electrical supply of the CRN 457 module before connecting the spray gun.
Before disconnecting the spray gun/ the atomizer, extinguish, switch off the power supply of the
CRN 457 (if not, a malfunction can occur).
WARNING : This equipment is intended for spraying powder paint only.
1.3. Guarantee
During the CRN 457 control module guarantee period, it is strictly forbidden to remove, attempt to
remove or cut the label (located under module) on pain of loss of guarantee.

2. Presentation
The “
Mach-Jet
”spray gun is a manual spray gun intended for powder spraying. It is connected to a
“
CRN 457
”control module that controls both the high-voltage and the powder flow rate of the spray gun
to which it is connected. These two indissociable elements constitute a manual powder-coating device.
This new spray gun integrates powder flow rate management and pre-programmed voltage and current
settings, which are adjustable from the control module.

3.2. Compressed air quality
Required characteristics for compressed-air supply according to standard NF ISO 8573-1:
*: Values are given for a temperature of 0˚ C (32˚ F) at an atmospheric pressure of 1,013 mbar.
WARNING : Non-compliance with these characteristics may result in incorrect operation of the
“CRN 457” control module.
WARNING : A 5µµ
µµ
filter must be installed upstream of the “CRN 457” control module compressed-
air supply system. The size of this filter depends on the size of the installation.
Sames Technologies advises to use a filter like the one indicated in section
(see § 10.6 page 46).
If any damage on the equipment happens because of a polluted air, the warranty could be not
applied.

4. Operation
The
Mach-Jet
spray gun is connected to the
CRN 457
control module via a serial link embedded in the
electrical connection cable. This link enables recognition of the spray gun and the exchange of data
necessary for operation.
Methods for modifying or adjusting settings are described in the following chapters. It is possible to return
to the original “factory”settings at any time (see §6.1 page 17).
In the case of a manual unit not connected to an industrial PLC
:
The first time the control module is started up, the operator selects the operating mode for powder feed;
two possibilities are proposed:
•Use of a vibrating table (factory parameter).
•Use of a round fluidisation tank.
WARNING : This use parameter can then be modified at any time in the “F” menu displayed on
the control module.
