NOMAD 2000 Marking System
2 of 8
84724A
SYSTEM SETUP
The marking head is designed to be used as a
handheld marker.
The following procedures provide only a general
overview of the operation process. For more
information, see the NOMAD 2000 Getting Started
Supplement, the NOMAD 2000 Installation &
Maintenance Manual, or the NOMAD 2000 Operation
Manual.
C A U T I O N
The NOMAD 2000 is not a sealed unit. See
Environmental Considerations for more
information.
1.
Place the controller on a flat, level, and stable
surface as close as practical to the marking
head. Standard marker cable length is 2 m (6.5
feet).
2.
To start the marking system software, press the
controller power button on the front panel to
ON.
3.
Load the pattern you want to mark.
4.
Adjust the pin stroke for impact depth as
necessary.
5.
Place the marking head on the correct location,
and mark the pattern.

Marking Characteristics
The NOMAD 2000 can accommodate character sizes
from .762 to 25 mm (.030 to 1.0 inch) in .025 mm
(.001-inch) increments. Characters can be rotated in
1° increments with printing resolutions from 5 dots/cm
(10 dots/inch) to 75 dots/cm (200 dots/inch) for an
engraved look.
Marking Speeds
The system marks a maximum of 2.0 characters per
second using a 5 x 7 font, 3 mm (.118-inch) high, 2
mm (.080-inch) wide characters. Speeds vary
depending on the selected character size, style, and
dot density. Specific times can be verified by a Telesis
representative.
Marking Noise
Sound pressure-level tests were conducted on the
Marking System using a Larson-Davis Model 710 sound
pressure meter while dry firing the marker at a 50%
duty cycle. The maximum sound pressure level during
the test cycle was measured at 80.4 dB. The time-
weighted average (LEQ) using the 3 db rule without
threshold was 72.5 dB. Typical applications average a
20% to 30% duty cycle where the time-weighted
average would not exceed 68.3 dB(A).
The sound pressure-level tests were carried out under
controlled conditions, imitating as closely as possible,
predicted normal operation. However, noise level is
heavily dependent on the part being impacted.
Conditions such as the material being marked, the
rigidity of the work piece, machine settings, ambient
noise, etc., may all vary when in operational use. Such
variables will alter the actual noise level.
Despite detailed guidance provided with each machine,
variable operating conditions are beyond the control of
Telesis. The responsibility of establishing safe working
levels of use remains with the end user. Accordingly,
you should conduct your own sound pressure-level
tests for your application while marking actual work
pieces.
Pin Life
Pin life depends largely on the type of material being
marked, how hard or abrasive it is, and the required
marking depth. On typical metals with a hardness of
Rockwell Rb47, marking at a depth of .127 mm (.005
inch), carbide pins average approximately 9 million
impressions before needing sharpened.
Marking Depth
The NOMAD 2000 can obtain a marking depth of .127
mm (.005 inch) in mild steel (Rb53) using a 25XLE
carbide pin with a 45° cone angle. The depth of mark
can be adjusted over a significant range by changing
the impact force (software parameter) or the impact
distance (pin stroke). Note the maximum pin stroke
distance is 3.8 mm (.15 inch). Specific depths can be
verified by a Telesis representative.
