Assembly and disassembly
14.1
General notes
Assembly and disassembly work on and with the monitoring unit may only be performed by an
authorised specialist familiar with the safety regulations governing handling electrical
components! When using EX-certified monitoring units in potentially explosive atmospheres, the
professional must also be familiar with the relevant safety regulations!
Meaning
No bearing damage can be detected. The bearing status
parameter is very low. It is recommended to repeat the
measurement or change the installation location.
If the bearing status parameter is still in range 1, this can be
approved as the normal range after a check (e.g. frequency and
time range analysis).
The bearing status parameter is in the normal range. The
parameter is in the typical normal status. There is no bearing
damage.
The bearing status parameter is in the warning range. It is
recommended to check bearing by means of a frequency and
time range analysis.
The bearing status parameter is in the alarm range. It is
recommended to consider changing the bearing.
Before assembly and disassembly disconnect the monitoring unit from the power
supply! Separate plug connections must always be de-energized! If EX-certified
monitoring is operated in a potentially explosive atmosphere, there is otherwise an
explosion hazard, due to spark formation!
The monitoring unit housing must be earthed via the fastening - through the
machine earth of the mounting surface or through a separate protective conductor (PE)!
