The personnel working on the sensor must regularly be trained and instructed by the operating
company.
2.3 Residual risks
2.3.1 Danger from electrical energy
The sensor is connected to the power supply via a 24-volt power supply unit. When connecting
the power supply to the sensor, check to ensure that the cable is routed correctly.
Prior to starting maintenance work or disassembly, pull out the mains plug, thus disconnecting
the sensor from the power supply.
Ensure that the electrical equipment of the sensor is checked at regular intervals. Defects, such
as loose connections, rubbed or scorched cables, must be eliminated immediately by a skilled
electrician.
Switch off the sensor immediately in the event of malfunctions in the electrical power supply.
2.3.2 Danger from magnetism
Powerful magnets are used to secure the sensor on surfaces. These magnets generate
electromagnetic fields that can affect cardiac pacemakers and similar devices. This can cause
cardiac pacemakers to malfunction. The electromagnetic field affects devices in the immediate
vicinity in an area of about 0.5 meters around the sensor. Persons with cardiac pacemakers
should not be inside this area.

Print version 03/2021, English
WARNING
Danger from strong magnets
The magnets generate strong electromagnetic fields that can affect and
interfere with electronic devices (such as cardiac pacemakers).
Malfunctioning cardiac pacemakers can cause death or serious injuries to
the persons concerned.
Persons with cardiac pacemakers are not allowed to be in the vicinity of
the sensor.
Persons with cardiac pacemakers are not allowed to work with or handle
the sensor.
Check this warning on the sensor or on the machine tool at regular
intervals. Replace damaged warning labels immediately.
The hazard exists even when the sensor is switched off. The magnets are always active.
Persons with cardiac pacemakers are therefore not allowed to perform any activities with the
sensor (neither transportation, startup, or disposal, nor service and maintenance).
In addition, check the warning labels on the machine tool for damage at regular intervals. These
pictograms are the only way to warn uninvolved persons of the magnets and to safeguard them.
To do this, comply with the information in the maintenance plan.
Powerful magnets are used to secure the sensor on surfaces, such as machine housings.
During the installation, the magnetic effect can pull the sensor instantaneously towards the
surface. This can squeeze the fingers of the fitter if he/she is not careful. This results in a slight
bruising of individual fingers or fingertips. To protect from squeezing, the sensor is equipped
with recessed grips on the housing. Combined with appropriate care, mounting the sensor is
thus possible without risk.
Magnets are used to secure the sensor on surfaces. The sensor can drop if there is only little or
no magnetic adhesion on the surface. The dropping sensor can bruise the feet of the fitter. The
sensor can be damaged when it drops on the floor.
Carefully approach the sensor to the surface to check its magnetic effect. While observing the
magnetic effect, hold the sensor by the recessed grips to prevent bruising your fingers.
Afterwards, watch the sensor for a short time to see if it moves and risks to drop down. Select a
different surface for mounting if the sensor moves.
2.3.3 Danger from leaks and hose lines
Hose lines connect the sensor with a coolant tank. If these lines are damaged or not installed
properly, there will be leaks, and coolant will escape.
Leaked coolant can cause injuries (risk of slipping, for example). Consequently, route the hose
lines carefully and free of tripping hazards. Prior to starting up the sensor, check the installation
of the hose lines at coolant tank and sensor. Observe the specifications in the maintenance plan
for regular inspections.
Hose lines connect the sensor with the coolant tank. These hose lines must be routed carefully
to prevent any risk of tripping. Persons tripping over hose lines can fall and injure themselves. In
addition, the lines or the connections on the sensor or the tank can be damaged and coolant
can escape in an uncontrolled way.
