Wiring

Important wiring note:
Note that the displace-
ment measuring system
must be connected to the
potential compensation system in
accordance with the specifica-
tions of DIN EN 60079-14. The
external connection for the
transducer is accomplished by
means of metallic conducting
installation in a grounded area.
The flange and housing are me-
chanically fixed together and
electrically identical, so that no
potential differences between
them can occur.
If no metallic conducting installa-
tion location can be assured, the
housing must be grounded using
the ground screw on the cover.
The system and the control cabi-
net must be at the same ground
potential. A sufficient potential
compensation has to be pro-
vided such that it does not flow
through the cable shield!
To ensure electromagnetic com-
patibility (EMC), which Balluff
verifies by the CE Marking, the
following points must be strictly
observed.
BTL transducer and processor /
controller must be connected
using shielded cable.
Shield: Copper-stranded mesh,
85 % coverage. The shield is
connected to the housing of the
transducer. It must be grounded
on the control side.
Unused leads can be tied to
GND on the control side, but
they must never be connected to
the shield.
Refer to table 4-1 for wiring
assignments.
For safety reasons the maximum
current load for the RS 485
interface is 20 mA.
The installed cable fitting
was tested with reduced
tensile force in accor-
dance with EN 60079-0.
This is why the connection cable
must be routed in a permanent
location and protected against
tension and rotary loads using an
additional clamp. It may not be
used with drag chains.
