No. 868145 EN ∙ J19; subject to modification. Replaces L16.
Screw the BTL 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 necessary (only
possible with a diameter of 10.2 mm).
If installed in a hydraulic cylinder, the magnet should not
make contact with the rod. Minimum bore diameter in the
support piston:

At least 13 mm
8 mm
At least 11 mm
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
– Regularly check function of the BTL and all associated
components.
– Take the BTL out of operation whenever there is a
malfunction.
– Secure the system against unauthorized use.
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 the BTL and controller using a shielded cable.
Shielding: Braided copper shield with minimum 85%.
– Connector version: 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, holding 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.
Bending radius for fixed cable
The bending radius for a fixed cable must be at least five
times the cable diameter.
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 (O-ring/flat seal).
