Magnets, Installation

A magnet is required for each trans-
ducer. This must be ordered sepa-
rately. ➥ ➥ ➥ ➥ ➥ Fig. 3-4.
For mounting the magnet we rec-
ommend to use non-magnetizable
material. ➥ ➥ ➥ ➥ ➥ Fig. 3-1.

Wiring

Note the following when making
electrical connections:
System and control cabi-
net must be at the same
ground potential.
To ensure the electromagnetic
compatibility (EMC) which Balluff
warrants with the CE Mark, the
following instructions must be
strictly followed.
BTL transducer and the proces-
sor/control must be connected
using shielded cable.
Shielding: Copper filament
braided, 80% coverage.
The shield must be tied to the
connector housing in the BKS
connector ➥ ➥ ➥ ➥ ➥ Figs. 4-3 and 4-5;
see instructions accompanying
the connector.
The cable shield must be
grounded on the control side,
i.e., connected to the protection
ground.
The Profibus bus line should be
routed according to the
PROFIBUS Technical Guidelines,
Assembly Guideline PROFIBUS-
DP/FMS.
Pin assignments can be found in
➥ ➥ ➥ ➥ ➥ Table 4-2.
When routing the cable between the
transducer, controller and power
supply, avoid proximity to high volt-
age lines to prevent noise coupling.
Especially critical is inductive noise
caused by AC harmonics (e.g. from
phase-control devices), against
which the cable shield provides only
limited protection.
The signal is sent to the controller
over the PROFIBUS-DP interface.
Max. cable length of the intire field-
bus: 1200 m
The transmission speed is a func-
tion of cable length. EN 50170 is the
reference for the values given in
➥ ➥ ➥ ➥ ➥ Table 4-1.
Cable length Baud rate [kbps]
< 100 m 12,000
< 200 m 1,500
< 400 m 900
< 1000 m 187.5
< 1200 m 93.7 / 19.2 / 9.6
Table 4-1:
Baud rate vs. cable length
The bus must be terminated at both
ends as per EN 50170. ➥ ➥ ➥ ➥ ➥ Fig. 4-2
The BTL5-T provides the option
of assigning the station address
and of terminating the bus inter-
nally using DIP switches. For
additional information see
➥ ➥ ➥ ➥ ➥ Section 7 Configuration.
