Safety information
This sensor has been designed for save use but must be operated with caution. If used properly according to this
user’s guide,
the Microfreeze poses no health concerns for the personnel.
4.1
General safety instructions
•
Check the voltage rating before you connect the equipment to an electrical power source to ensure that
the required voltage and frequency match the available power source.
•
Do not connect the equipment power cables the power outlet if the power cable is damaged.
•
If you use an extension power cable, ensure that the total ampere rating of the products plugged in to
the extension power cable does not exceed the ampere rating of the extension cable.
WARNING:
The customer is responsible to connect all metal parts of the Microfreeze to protective earth via a
low resistive path (< 1 Ohm).
WARNING:
A minimum distance of 1 meter from the emitter unit should be respected to stay within the
maximum electromagnetic exposure limit.
CAUTION
: If any smoke or unusual odours are detected, disconnect the device from the electrical outlet and
contact Aquantis immediately. See page 2 for the appropriate contact information.
4.2
Laser classification (Class II)
The Microfreeze sensor system includes a visible class 2 laser for measuring the product (layer) thickness. The
laser-beam is normally pointed downwards to the conveyor belt on which the products pass. Do not stare into
the beam or direct the beam to anyone’s eyes.
WARNING: Do not directly view or point the laser pointer at an eye.
Low power visible lasers do not normally
present a hazard but may present potential for hazard if viewed directly for extended periods of time.
Permitted sensor uses:
The Microfreeze system is designed for use in industrial environments
▪
Measure LOF of products (layers) on a conveyor belt or free-fall.
▪
Measure product thickness of products (layers) on a conveyor belt or free-fall.
No other uses are permitted.
Prohibited sensor uses:
▪
Compromising or deactivating safety systems built into the sensor
▪
Removal of hazard or explanatory labels affixed to the sensor
▪
Opening the sensors enclosure (during operation or cleaning)
▪
Modifying or converting the instrument
▪
Using third party accessories
Notices:
▪
Avoid shocks and impacts to the sensor.
▪
Protect the sensor cables against damage.
▪
Avoid exposure of sensor to aggressive media.
▪
Mount the sensor only by means of the foreseen mounting spaces according to the installation
guidelines.
