Shielding and cable routing 5.1
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.
Shield: Braided copper shield with minimum 80%.
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.
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
BTL5-A/G Max. 20 m
1)
BTL5-C/E Max. 50 m 1)
1)
Prerequisite: Construction, shielding and routing preclude the effect of any
external noise fields.
Cable lengths BTL5 Tab. 5-1:
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 –
BTL5 is located to the same ground potential.
Starting up the system 5.2
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.
Startup must be performed only by trained technical
f
personnel.
Observe the safety instructions of the equipment or
f
system manufacturer.
Check connections for tightness and correct polarity. 1.
Replace damaged connections.
Turn on the system.
2.
Check measured values and readjust the transducer, if 3.
necessary.
Check for the correct values at the null point
and end point, especially after replacing the
transducer or after repair by the manufacturer.
Operating notes 5.3
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. –
