Installation & commissioning of sensor unit
The operator of the system must ensure that the following condi-
tions are met and all necessary preparations are completed.
location of installation
• The sensor unit must be mounted on or near the machine.
Choose a suitable position on the machine that is only exposed
to low vibration. Alternatively, provide a suitable holder for the
sensor unit.
• Ensure that the location of installation has good radio reception.
Measure the reception field strength at several, potentially suit-
able installation points (see “Measuring reception field strength
at location of installation”, page 38).
• The distance between the measuring point and the sensor unit
can be bridged with the 2.9 m sensor cable; before mounting
the sensor unit and the sensors, ensure that they are not more
than 2.9 m apart.
Permissible ambient conditions
Temperature range for sensor unit: – 25 °C to +80 °C
Relative air humidity: max. 95 %, non-condensing
The sensor unit must not be installed in a location that is near
a strong electromagnetic field (e.g. generator, high-voltage cable,
electric drive unit, etc.).
