Shielding and cable routing
Defined ground!
The transducer and the control cabinet must be
at the same ground potential.
Shielding
To ensure electromagnetic compatibility (EMC), observe
the following:
– Connect the transducer and controller using a shielded
cable.
Shielding: Copper filament braided, at least 85%
coverage.
– Connector version: Shield is internally connected to
connector housing.
Magnetic fields
The position measuring system is a magnetostrictive
system. It is important to maintain adequate distance
between the transducer cylinder and strong, external
magnetic fields.
Cable routing
Do not route the cable between the transducer, controller,
and power supply near high voltage cables (inductive stray
noise is possible).
The cable must be routed tension-free.
Cable length
BTL7-A/G Max. 30 m 1)
BTL7-C/E Max. 100 m 1)
1) Prerequisite: Construction, shielding and routing preclude the effect of
any external noise fields.
Installation
NOTICE!
Interference in function
Improper installation can compromise the function of the
transducer and result in increased wear.
f The mounting surface of the transducer must make
full contact with the supporting surface.
f The bore must be perfectly sealed (O-ring/flat seal).

1) Unassigned leads can be connected to GND on
the controller side but not to the shield.
2) Reference potential for supply voltage and
EMC-GND.
To achieve a secure mounting, attach the transducer with
all 6 cylinder head screws (ISO 4762, M6 × 16 - A2-70). All
screws must be tightened to 3.5 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 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.
f Persons must keep away from the system's
hazardous zones.
f Startup must be performed only by trained technical
personnel.
f 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
regularly (especially after replacing the transducer or
after repair by the manufacturer). Recalibrate the
transducer, if necessary.
The calibration procedure is described in the
comprehensive user's guide.
