but not to the shield.
Shielding and cable routing
Defined ground!
The transducer and the control cabinet must be
at the same ground potential.
Magnetic fields
The sensor operates according to the eddy current prin-
ciple. It is important to maintain adequate distance bet-
ween the sensor and strong, external magnetic fields.
Cable routing
Do not route the cable between the sensor, controller, and
power supply near high voltage cables (inductive stray
noise is possible).
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.
Cable length
Max. cable length 20 m. Longer cables may be used if
their construction, shielding and routing prevent noise
interference.
Installation
NOTICE!
Improper installation
Improper installation can compromise the function of the
sensor and result in damage.
► For this reason, ensure that no strong electrical or
magnetic fields are present in the immediate vicinity
of the sensor.
Notes on installation:
– Any orientation is permitted.
– Install BAW M12MI-BLC35C-S04G flush.
– Install BAW M12MH-BLC70G-S04G with clearance.
– Observe tightening torques, see figure.

Startup
DANGER
Uncontrolled system movement
When starting up, if the distance 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 hazar-
dous 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
and readjust the sensor, if necessary.
Check for the correct values at the null point
and end point, especially after replacing the
sensor or after repair by the manufacturer.
Operating notes
– Check the function of the positioning system and all
associated components on a regular basis.
– Take the positioning system out of operation whenever
there is a malfunction.
– Secure the system against unauthorized use.
