BTL PF _ 400- _ _ _ _ -C15A _ _ _ _ - _ _ _ _ _ _
Magnetostrictive Linear Position Sensor – Profile Style
Installation (continued)
The magnetostrictive linear position sensor is electrically
isolated from the machine with the supplied insulating
bushes.
1. Guide the BTL into the mounting clamps.
2. Attach the BTL to the base using mounting screws
(tighten screws in the clamps with max. 2 Nm).
3. Install the magnet (accessory).
The magnetostrictive linear position sensor in
profile housing is suitable both for floating, i.e.
non-contacting magnets and for captive
magnets (see images).

Electrical connection

Depending on the model, the electrical connection is made
using a cable or a connector.
Note the information on shielding and cable
routing.

can be connected to
the GND on the
controller side but
not to the shield.

and EMC-GND.
Shielding and cable routing
Defined ground!
The BTL and the control cabinet must be at the
same ground potential.
Shielding
Observe the following instructions to ensure
electromagnetic compatibility (EMC):
– Connect BTL and controller using a shielded cable.
Shielding: Braided copper shield with minimum 85%
coverage.
– Shield is internally connected to connector housing.
Magnetic fields
The position measuring system is a magnetostrictive
system. Ensure that there is sufficient distance between
the BTL and the transducer/holding cylinder and strong,
external magnetic fields.
Cable routing
All cables between BTL, control and power supply must
be routed tension-free. In order to avoid electromagnetic
interference, ensure sufficient distance to cables carrying a
heavy current and cables with high-frequency voltage
signals (e.g. of frequency converters).

Green Normal function
Warning
Yellow flashing,
3 Hz Magnet is outside the measuring
range.
Red flashing, 1 Hz Measurement error
No magnet
Red flashing, 3 Hz Output error
Short-circuit at voltage output or
interruption on current output.
1) Is only displayed for versions with 2 current outputs if the error is
present at the same time at both outputs.
With 1 magnet and 2 outputs the priority of the LED
display is as follows (highest to lowest priority):
Output error, measurement error, Warning, ormal function
For FMM (Flexible Magnet Mode) with 1 magnet the LED
display relates to output 1 (output 2 issues the error value
continuously).
For FMM (Flexible Magnet Mode) with 2 magnets the LED
display shows the status with the highest priority of both
outputs.
More than 2 magnets are ignored.
