Installing
Before carrying out the following operations, make sure the machine is switched off and
unplugged, switch (L) to position 0 (photo 1).
Physical installation advice
•PuttheGravographmachineontoastableat,cleansurfacewithmini.sizesof 12.2" x 13.4" (310 x 340 mm).
Make sure the machine is well-ventilated (pict. 1 and 2). Do not prevent the air circulation under the machine.
•Cleartheworksurfacesothatyoucan
-easilyandquicklyaccessallexternalpartsofthemachine,
- quickly gain access, in case of necessity, the general shutdown button (L) of the machine,
- make sure that all moving parts of the machine have enough room to move freely,
- avoid any accidental unplugging of the cables.
The machine’s power supply cable being used as a sectionning device, it must be easily
accessible and the wall plug must be installed near the machine and must also be easily
accessible.
The connectors screws must be very tight to avoid accidental disconnection of the cables
while the machine is turned on as this could permanently damage the electronic cards
(label ).
•ProtectGravographequipementagainst:
- Moisture (rain, snow, condensation…),
- Heat (direct sunlight, heating…),
- Brusque temperature changes,
-Dust(exhaustpipe),
- Liquid splashes, spillages on the electronic rack, cables and connections, and any other part of the machine;

Electric installation advice
This material is «class 1». The mains plug MUST always be connected to a neutral socket
and comply with the regulations in force in the country of installation. If you do not have
a plug of this type, have one installed by an approved electrician. Under no circumstances
should you depart from this instruction.
In order to avoid outside interference, the user is advised to carry out the following points.
• PlugtheGravographmachineintoamainsline,avoidinghavingseveralmachinesonthesameline(severalplugson
the same line or using a multi-plug).
Exception : If other things are connected to the machine (such as a computer and the M20 PIX
engraving machine), the machines should be connected to the same mains line.
• Avoid usingthe same line tosupplyinductiveor capacitive machines as wellasthe Gravographmachine (motors,
electrosluices, chargers...)
• AvoidusingamanualorautomaticcommutatoronthesamemainslineastheGravographmachine(relay,temporiser,
programmer, automatic circuit interrupter, automatic interrupter...).
• CheckthatmachinessurroundingyourGravographmachineareinconformitytothenormsofradioelectricperturba-
tionemissions(consultthetechnicalleaetofeachmachine).Iftheyarenotinconformity,placethemasfarawayas

• OnlyuseGravographaccessories.
The machine must always be switched off before connecting or disconnecting a cable
(label ).
Electrical connections of the machine
Position yourself behind the machine.
1. Plug power supply cord oftheexternal
power supply of the machine into the
External power supply connection of
the M20 PIX machine.
2. Plug power supply cord into the ex-
ternal power supply of the machine
and then into the mains socket.
To cut off the mains supply to
your machine in the case of
severe problems, unplug the
mains cable or switch off
the machine with the main stop
button at the side of the
machine. Make sure that you
can reach them easily.

Connecting the M20 PIX machine to a PC
The computer and the M20 PIX Machine must both be switched off.
As PCs and the Windows®graphical environment are in widespread use in the IT sector,
we have used these products as the basis for dening the installation and operating pro-
cedure for the M20 PIX machine
If you don’t have equipment which is compatible and you encounter some problems of installation or use, contact your
Gravograph agent.
Connection cables
• UseGravographconnectioncables(consultyourGravographdistributorfortheproductsavailable).
These cables are adapted for the machines to which they will be connected.
They must be in conformity with the electromagnetic compatibility standards, norm EN 55022 - class B and protect
fromexternalelectric«attacks»(conformtothenormsofimmunityandCEMsusceptibility).
• Donotusecableswhicharetoolong.Keepthemachinesascloseaspossibleanduseashortacableaspossible.

Switching the machine on
Switch on the machine main stop button (L) to position I.
The machine will then emit a short «beep».
Leave the machine plugged in even if it is not in constant use.
Problems
If one of the operational signs is absent, check the following points :
•Arethetwoendsofthemainscablecorrectlyconnected?
•Isthemainsplugconnected?Isitlive?
If the machine does not come on, before calling a technician, please check power connec-
tions to the mains socket.
Switching the machine off
Switch the main stop button (L) to position 0.
Switchoffthemachineforthefollowingreasons:
-ifyouareleavingtheworkstation(endoftheday,forexample),
-physicaldamage(fall,re,liquidscomingintomachine…),
- mechanical/electrical/electronic faults, leading to a possible breakdown,
- in case of major problem or mechanical block of the machine,
- to reboot,
- for external cleaning.
Mechanical block
In the following cases :
- danger for the operator,
- block on the support to be engraved,
- block on an object placed in the work area,
1. Cut the power supply by switching the main stop button (L) to position 0.
2. Free the tool, without switching the machine on, by manually and slowly moving the tool holder
as required.
3. Only switch the machine back on after ensuring that the tool's moving area is totally clear.
Switching on again
If the machine or the programme which runs it crashes you may have to reboot the machine.
If this happens, switch the machine off. Wait 30 seconds and switch it on again.
Respect this rule. This time allows any electric shock to the machine, possibly damaging
the power supply, to be avoided
