1.1 Intended Use
This product is a hydraulic component.
This device is an optical particle monitor used to monitor the
cleanliness of fluids. It uses the principle of light extinction
(attenuation of radiation) and measures particles in the fluid.
The measured values were converted into standardised clean-
liness classes and output on the display. Various ports can be
used to read and transmit the measurement data.
It connects to the system with the fluid via two Minimess©
M16x2 ports.
The product may be used as follows:
• Monitoring the cleanliness of a fluid,
• Contamination level trend analysis.
The product is only intended for professional use, not for
private use.
The intended use also includes reading and understanding
this documentation, particularly chapter Safety instructions
in full.
1.1.1 Improper Use
Any use not specified under intended use is considered im-
proper use, thus prohibited.
Installing or using unsuitable products in safety-related ap-
plications can cause intended operating states in the applica-
tion resulting in personal injury and/or property damage.
Therefore only use a product for safety-related applications if
this use is expressly specified and permitted in the product
documentation. For example, in Ex protection areas or in
safety-related parts of a control unit (functional safety).
Conveying media other than those listed in chapter Technical
Data is prohibited.
Bühler Technologies GmbH assumes no liability for damages
due to improper use. The user is solely responsible for the
risks associated with improper use.

CAUTION
Laser
The particle monitor contains a laser which, when used prop-
erly, is classified as a Class 1 laser according to
DIN EN 60825-1:2001-11. The accessible laser beam is safe un-
der reasonably foreseeable conditions.
In Class 1 laser equipment, e.g. blinding, impairment of colour
vision and nuisance cannot be ruled out in the upper per-
formance range.
