Magnetostrictive Linear Position Sensor – Rod Style
Shielding and cable routing
Defined ground!
The BTL and the control cabinet must be at the
same ground potential.
Shielding
To ensure electromagnetic compatibility (EMC), observe
the following:
– Connect BTL and controller using a shielded cable.
Shielding: Braided copper shield with minimum 85%.
Magnetic fields
The position measuring system is a magnetostrictive
system. It is important to maintain adequate distance
between the BTL cylinder and strong, external magnetic
fields.
Cable routing
Do not route the cable between the BTL, controller, and
power supply near high voltage cables (inductive stray
noise is possible). The cable must be routed tension-free.
Inductive stray noise from AC harmonics (e.g. from phase
angle controls) are especially critical and the cable shield
offers very little protection against this.
The signal is transmitted to the controller via the
CANopen interface.
Preferably use a shielded cable where wires 2
and 3 and wires 4 and 5 are twisted.
The transfer rate is dependent on the cable length, whe-
reby the cable length is limited to a maximum of 2500 m
(Ø 6 to 8 mm) (see table).

Installation
NOTICE!
Interference in function
Improper installation can compromise the function of the
BTL and result in increased wear.
► The mounting surface of the BTL must make full
contact with the supporting surface.
► The bore must be perfectly sealed (flat seal).
Screw the BTL with mounting thread into the mounting
hole (max. torque 100 Nm).
For horizontal assembly with nominal lengths > 500 mm,
support the rod and tighten it at the end if necessar.
If installed in a hydraulic cylinder, the magnet should not
make contact with the outer rod. Minimum bore diameter
in the support piston:

Startup
DANGER
Uncontrolled system movement
When starting up, if the position measuring system is
part of a closed loop system whose parameters have not
yet been set, the system may perform uncontrolled
movements. This could result in personal injury and
equipment damage.
► Persons must keep away from the system's
hazardous zones.
► Startup must be performed only by trained technical
personnel.
► Observe the safety instructions of the equipment or
system manufacturer.
1. Check connections for tightness and correct polarity.
Replace damaged connections.
2. Turn on the system.
3. Check measured values and adjustable parameters
(especially after replacing the BTL or after repair by the
manufacturer). Recalibrate the BTL, if necessary.
Operating notes
– Check the function of the BTL and all associated
components on a regular basis.
– Take the BTL out of operation whenever there is a
malfunction.
– Secure the system against unauthorized use.
