requires that you observe all information, instructions, safety notes and warning messages in this operating
manual. The specifications given in chapter17 „Technical data“ on page88 apply. Any given limit values
must be complied with.
If not used as intended, the device or the system in which the device is installed can be damaged or de-
stroyed. In addition, there is an increased risk to health and life. Only use the device in such a way that there
is no risk of injury.
This operating manual is an integral part of the device and must be kept in the immediate vicinity of the place
of use, accessible to personnel at all times.
Every person who is responsible for the installation, start-up or operation of the device must have read and
understood the operating manual and, in particular, the safety instructions.
If you still have questions after reading this operating manual, please contact PRIMES or your supplier for
your own safety.
Observing applicable safety regulations
Observe the safety-relevant laws, guidelines, standards and regulations in the current editions published by
the state, standardization organizations, professional associations, etc. In particular, observe the regulations
on laser safety as well as machine safety and comply with their requirements.
Before commissioning, it must be ensured that the entire machine in which the device is installed meets
these safety requirements. Otherwise the commissioning of the device is prohibited.
Necessary safety measures
The device measures direct laser radiation, but does not emit any radiation itself. However, during the mea-
surement the laser beam is directed at the device. This produces scattered or directed reflection of the laser
beam (laser class 4). The reflected beam is usually not visible.
Protect yourself from direct and reflected laser radiation while working with the device by taking the following
measures:
• Wear safety goggles adapted to the power, power density, laser wavelength and operating mode of the
laser beam source in use.
• Wear suitable protective clothing or protective gloves if necessary.
• If possible, also protect yourself from direct laser radiation and scattered radiation by using separating
protective devices that block or attenuate the radiation.
• If the device is moved from its aligned position, increased scattered or directed reflection of the laser
beam occurs during measuring operation. Mount the device in such a way that it cannot be moved unin-
tentionally, i.e. by bumping or pulling the cables
• Install safety switches or emergency safety mechanisms that allow the laser to be switched off immedi-
ately.
• Use suitable beam guidance and beam absorber elements which do not emit any hazardous substances
when irradiated.
Employing qualified personnel
The device may only be operated by qualified personnel. The qualified personnel must have been instructed
in the installation and operation of the device and must have a basic understanding of working with high-
power lasers, beam guiding systems and focusing units.

4.2 Functional description
The PMM is used to measure laser power. After opening the shutter, the laser beam hits the absorber and
scattering light is registered by a photodiode. The absorber and the photodiode are protected from contami-
nation by the protective window. The shutter and the caps on the ports protect the PMM from contamina-
tion. Thus, the PMM can be used directly in the production environment in the process zone.
The PMM operates without cooling water and compressed air. The absorber cools off only through thermal
conduction to the ambient air.
Thanks to the availability of various fieldbus interfaces, the PMM can be integrated in nearly every existing
machine. The measurement results are transferred directly to the PLC.

4.3 Measuring principle
The PMM offers a fast, passively cooled power measurement according to the calorimetric measuring prin-
ciple. The absorber of the measuring device is briefly irradiated with the laser beam. The irradiated energy is
determined by the temperature rise of the absorber.
The photodiode simultaneously determines the laser ontime. The high-frequency sampling rate of the
photodiode enables single pulse detection for pulses not shorter than 50μs.
Thus, in addition to the average power, the peak power can also be calculated. In the second step, the ac-
tual laser power is calculated from the absorbed energy divided by the laser ontime.

4.4 Explanation of the product safety labels
Potential hazard areas are marked on the device with the symbols „Do not grab inside“ and „General warning
sign“.
4.4.1 Warning of hand injuries/damage to the device
Do not grab inside
Under the protective window is an opening with the absorber. Touching the hot absorber can cause seri-
ous burns. Touching the absorber can lead to burn-in by the laser radiation at the points of contact. Burn-in
causes damage to the absorber and increases the scattered radiation. Do not grab inside the opening.
General warning sign
The protective window is hot after a measurement! Do not replace the protective window directly after a
measurement. Let the device cool down for an adequate period of time.
Contamination and fingerprints on the protective window can lead to damage or destruction of the protective
window during measuring operation. When exchanging the protective window wear suitable gloves.
Fig. 4.3: Product safety labels „Do not grab inside“ and „General warning sign“
4.4.2 Warning of internally connected power ports
The product safety label „General warning sign“ indicates that the power connections are internally con-
nected 1: 1. Please refer to the information on the pin assignment of these two user interfaces in chapter7
„Connections“ on page21.

6 Mounting
6.1 Conditions at the installation site
• The device must not be operated in a condensing atmosphere.
• The ambient air must be free of gases and aerosols that interfere with the laser radiation (e.g. organic
solvents, cigarette smoke, sulfurhexafluoride).
• Protect the device from splashes of water and dust.
• Operate the device in closed rooms only.
6.2 Installation in the laser system
6.2.1 Prepare mounting
1. Switch off the laser beam.
2. Ensure that moving parts, e.g. robot arms, etc. are at a standstill and that they cannot be set in motion
unintentionally.
NOTICE
Damage/Destruction of the device
During operation, the shutter of the device is fully opened. Obstacles in the traveling path of the
shutter can damage the device.

Before installing the device, check that a collision of the shutter with the laser system is not pos-
sible. A dimensioned view of the swivel range can be found in chapter18 „Dimensions“ on
page91.
3. Check the space available before installing the device, especially the required space for the connection
