5 Startup
5.1 Check connections
Although the connections are polar-
ity reversal protected, components
can be damaged by improper con-
nections and overvoltage. Before
you apply power, check the connec-
tions carefully.
5.2 Turning on the system
Note that the system may execute
uncontrolled movements when first
turned on or when the transducer is
part of a closed-loop system whose
parameters have not yet been set.
Therefore make sure that no haz-
ards could result from these situa-
tions.
5.3 Check output values
After replacing or repairing a trans-
ducer, it is advisable to verify the
values for the start and end position
of the magnet in manual mode. If
values other* than those present
before the replacement or repair are
found, a correction should be made.
* Transducers are subject to modifi-
cation or manufacturing tolerances.
5.4 Check functionality
The functionality of the transducer
system and all its associated com-
ponents should be regularly
checked and recorded.
5.5 Fault conditions
When there is evidence that the
transducer system is not operating
properly, it should be taken out of
service and guarded against unau-
thorized use.
