Grounding connection

The marking equipment must be grounded in order to provide:

- a safety feature for personnel

- a set electrical potential which serves as a reference

- a means of protection against radiated parasites

High quality grounding is necessary on-site. If thi s is not the case, put in place
grounding specifically for the equipment.

3. Coordinate system

The coordinate system used in our machines is shown in the following diagram.

1 : Axis origin
2 : X axis
3 : Y axis
4 : Z axis
5 : Column
6 : Marking zone

D

• X axis: horizontal axi s going from left to right

• Y axis: horizontal axis going from the column to the operator

• Z axis: vertical axi s
When a marking cycle is launched, the stylus al ways begins at t he origin point and retu rns to the origin at the end

of the cycle.
The coordinates are given as an absolute val ue in rel ation to this point.
The Z axis is the v ertical position. Thi s axis is used to manually adjust the height of the stylu s for marking parts of

different sizes.
A vertical positioning indi cator can be found on the right side of the machine.

AInstallation

4. Hold the part to be marked

Situation 1

Used with Pro-Pen plate-holder (optional)
To mark plates or small par ts with a thickness of less than 2 mm (0.079 in), use the pl ate holder to position the

parts and prevent them from vibr ati ng when the stylus taps.

Situation 2

No plate-holder used
To mark small or large parts, create the necessar y tool ing to position and clamp the part s un der the machine. If

the part is flexible, thi s tool ing must provide firm support under the p art to be marked. It must be held on the
worktable using the three T grooves . The position of the marking zone with relation to the T groov es is i ndicated
on the dimensional drawing of the worktable.

A poorly clamped piece c an g enerate high sound l evels, t hus becom ing har mful after long periods.

D

5. Adjusting the height of the stylus

Determining the optimum operating di stance of the stylus according to th e part to be marked.
This distance is between 1 mm (0.039 in) and 5 mm (0.197 in).
Using feeler gauges, position t he point of the stylus 2 mm (0.079 in) above the part to be marked.
Execute a marking.
The whole marking line should be legible.
Depending on the results, increase or decrease the distance between the stylus and the marking surface.

• If a stylus is set too high, it doesn’t mark because the poi nt doesn’t touch the plate
consistently while traci ng the characters.

• If the stylus is set too low, it doesn’t mark because it cannot vibr ate. The point withdraws
inside the stylus and remains in permanent contact with the plate.

Maximum adjustment distance

Carry out a series of markings while progressively lowering the head until a
uniform marking is obtai ned. With the help of feeler gauges, measure the
distance between the point of the st ylus at rest and the marked surface. Make a
note of this distance.

Minimum adjustment distance

Lower the head until the stylus i s barely touching the part to be marked. Raise
the head and set the distance from the point of the stylus to the surface to be
marked at Do (optimal distance), betwee n 0.5 mm (0.02 in) and 1 mm (0.039 in).

Amplitude of a stylus

Subtract the min. dist ance (Dm) from the max. distance (DM) to obtain the
operating amplitu de of the st ylus. This distance corr esponds to its operating
range, or its capacity to absorb variations in flatness.

Optimum adjustment distance

Take the average of the DM and Dm. Position the stylus at this distance (Do).

EMarking depth

1. Factors influencing marking depth

The principle factors are:

• choosing the stylus

• distance between the stylus and the part

• selecting solenoid valves (m arking force)

• choosing the marking speed

To avoid creating stress on fragile part s, choose the following marking parameters:

• stylus PN12 is the preferable choice.

• choose a point with the largest possib le radius.

• select marking force 25% for the marking file.

For very fragile parts, validate marking with mechanical resistance tests.



Choosing the stylus

E

Two pneumatic styli, each with a different force are available: PN12 and PN22. The force varies according to the
diameter of the tip of the point.

The points come sharpened to a r adius of 0.2 mm (0.00 8 in). Depen ding on the nee d, points can be shar pened to
different radii ranging from 0.1 mm (0.004 in) to 0.5 mm (0.02 in).

Stylus PN12 Stylus PN22

A PN22 stylus with a po int radius sharpened to 0.2 mm (0.008 in) comes standard with the mac hine. This point is
suitable for most common marking needs. A PN12 stylus is available upon request.

Ref. 9207 4 - P5000 PN_en_D

24/35

AMarking depth



Distance between the stylus and the part

The optimum distance (Do) of the stylus in relation to the surface to be marked decreas es as the marking force
decreases.

Using a stylus which is positioned too low, or which is too powerful i n rel ati on to the
hardness of the material, will result in distorted characters.

If the stylus is set too high, the marking will be lighter but there will be portions of the
characters marked which will be missing. In this case, choose a less powerful stylus .

The max. distance (DM) and min. distance (Dm) may vary slightly from one stylus to another (production
tolerances for stylus components, pressure and comp ressed air flow through the system). To mark curved parts
using the maximum amplitude (A), set the stylus at the minimum dist ance (Dm) above the highest point of the
part.



Selecting solenoid valves

The number of solenoid valves, selected from the marking program, will determine the width of the mark. Choose
a marking force according to the amount of compressed air required. The table below shows the number of
solenoid valves activated depending on the marking force, and the appropriate stylus to use with each force.

FPreventive maintenance

The maintenance operations listed here are intended as a guideline, and should be implemented upon reception
of the material. In a highly polluted environment, these operations may need to be performed more frequent ly.

Unplug the power supply plug before beginning any cleaning or maintenance operation.

This maintenance list was established based on a marking frequency of:

• 520 000 cycles per year (7 800 000 characters per year)

• 15 characters 3 mm (0.118 in) high per cycle

2

• 8 continuous working hours on steel strength 50 DaN/mm

(72518.869 lb/in2)

1. Every week

• Clean the guide bars inside the marking head with a dry cloth (no solvent, oil, or grease).

• Dismantle the stylus. Remove the point.

• Check the condition of the styl us, then clean it thoroughly.

• Clean the point with a dry cloth.

• Empty the air filter in ord er to el iminate dust or liquid
which may be present in the system. Clean, dry, non­lubricated air will reduc e the bui ld-up of grease in the
solenoid valves. This will ensu re optimal functioning
and reliability of the stylus.

GGeneral maintenance

1. General information

Maintenance consists of regul ar monitoring of marking quality. Intensive use of the equipment can impact the
guiding systems of the carriage or the styl us point, and may result in distortion of th e characters.

Contact your distributor to schedule an appointment for servicing. This "tune-up" does not take a long time.
Check the compressed air system regularly. Based on the level of soiling, establish a schedule for cleaning or

replacement.
Never lubricate any part of the stylus or carriage guide bars.
If the machine is equipped with a pressure regulator filter, empty it regularly.

• Never lubricate any element s of the stylus.

• Never use pliers to tighten the styl us.

• Never lubricate any element of the marking head.

• Purge the filter of the pressure regulator regularly.

• The air pressure should be at 5.5 Bar (79.771 PSI) nominal, 6 Bar (87.023 PSI)
maximum, and must not go below 5 Bar (72.519 PSI).

• The air must be clean and dry.

G

Unplug the power supply plug before beginning any cleaning or maintenance operation.

2. Detaching the point of the stylus for sharpening

The tip of the point is made from a grade of carbide suitable for creati ng impacts. The point should be rounded in
order to hold up well on hard material.

To remove the point of the stylus, moisten the seal very slightly with a drop of oil, then push up on the stylus from
the pointed end.
