Electrical Connection - Balluff BTL7-P511-M Serie Instrucciones Breves

BTL7-P511 -M _ _ _ _ -P-S32/KA_ _
Micropulse Transducer in a Profile Housing
Installation (continued)
In order to avoid the development of resonant
frequencies from vibration loads, we
recommend arranging the mounting clamps at
irregular intervals.
The transducer is electrically isolated from the machine
with the supplied insulating bushes.
1. Guide the transducer into the mounting clamps.
2. Attach transducer to the base using mounting screws
(tighten screws in the clamps with max. 2 Nm).
3. Insert magnet (accessories).

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 transducer and controller using a shielded
cable. Shielding: Braided copper shield with minimum
85% coverage.
– Connector version: Shield is internally connected to
connector housing.
– Cable version: On the transducer side, the cable
shielding is connected to the housing.
Magnetic fields
The position measuring system is a magnetostrictive
system. It is important to maintain adequate distance
between the transducer and strong, external magnetic
fields.

Shielding and cable routing (continued)
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.
Cable length
Max. 500 m 2)

2) Prerequisite: Construction, shielding and routing preclude the effect of
any external noise fields. Required cable cross-section ≥ 0.6 mm
≤ AWG19
Noise elimination
To avoid equipotential bonding – a current flow – through
the cable shield, please note the following:
– Use insulating bushes.
– Put the control cabinet and the system in which the
transducer is located to the same ground potential.
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 readjust the transducer, if
necessary.
Operating notes
– Check the function of the position measuring system
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.
