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.
– Horizontally connect the shield in the connector to the
plug housing.
– Cable version: On the transducer side, the cable
shielding is connected to the housing.
Ground the cable shielding on the controller side
(connect with the protective earth conductor).
Magnetic fields
The position measuring system is a magnetostrictive
system. It is important to maintain adequate distance
between the transducer/holding 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 and stationary.
The bending radius must be at least five times the cable
diameter.

Installing the transducer
NOTE!
Improper installation
Improper installation can compromise the function of the
transducer and result in increased wear.
The flange surface of the transducer must make full
f
contact with the mounting surface.
The bore must be perfectly sealed (O-ring/flat seal).
f
Only use the proper nut for the fastening screw thread.
Firmly tighten the transducer with a maximum torque of
100 Nm.
If installing horizontally with nominal lengths > 500 mm, we
recommend tightening the outer rod at the end (only
possible with Ø 10.2 mm) or supporting it.
If installed in a hydraulic cylinder, the magnet may not
scrape against the outer rod. Minimum bore diameter in
the support piston:
Tube diameter
10.2 mm

Starting up the system
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
f
hazardous zones.
f Startup must be performed only by trained technical
personnel.
Observe the safety instructions of the equipment or
f
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 transducer). Re-adjust
the transducer, if necessary.
The adjustment processes are described in the
comprehensive user's guide.
Operating notes
– Check the function of the transducer and all associated
components on a regular basis.
– Take the position measuring system out of operation
whenever there is a malfunction.
– Secure the system against unauthorized use.
