Installation (continued)
Only use the proper nut for the mounting thread. Firmly
tighten the transducer with a maximum torque of 100 Nm.
For horizontal assembly with nominal lengths > 500 mm,
support the rod and tighten it at the end if necessary.
If installed in a hydraulic cylinder, the magnet should not
make contact with the rod. Minimum bore diameter in the
support piston:
Tube diameter
10.2 mm
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: Braided copper shield with minimum 85%
coverage.
– 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.

Bending radius for fixed cable
The bending radius for a fixed cable must be at least five
times the cable diameter.

1) Prerequisite: Construction, shielding and routing preclude the effect of
any external noise fields.
Startup
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
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.
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.
3) The voltage outputs may exhibit a
minimal offset to the harmonized current
output.
