Start-up

5.1

Check connections

Although the connections are polar-
ity reversal protected, components
can be damaged by improper con-
nections and overvoltage. Before
you apply power, check the con-
nections carefully.
5.2

Turning on the system

Note that the system may execute
uncontrolled movements when first
turned on or when the transducer is
part of a closed-loop system whose
parameters have not yet been set.

Setup and calibration

Please note:
The calibration device is to be at-
tached to the connection end of
the transducer, ➥ ➥ ➥ ➥ ➥ Figs. 3-2 and
6-1. Connect the transducer to the
controller. To monitor the calibra-
tion procedure, a display (controller
or multimeter) which displays the
BTL voltage or current levels is
required. All settings are done with
a magnet within the stroke area.
Please verify that the absolute null-
and endpoints are always within the
maximum and minimum possible
output values, ➥ ➥ ➥ ➥ ➥ Value table 7-1 on
page 8.

Check output values

After replacing or repairing a trans-
ducer, it is advisable to verify the
values for the start and end position
of the magnet in manual mode. If
values other* than those present
before the replacement or repair are
found, a correction should be
made.
* Transducers are subject to modifi-
cation or manufacturing tolerances.
Any desired magnet position within
the factory set nominal stroke length
can be assigned with a null- or end-
point. The null- and endpoint may
not however be reversed.
Once the calibration procedure is
concluded, the calibration device
can be removed to prevent acciden-
tal changes and to store in a safe
place for the next use.
The examples shown in this hand-
book refer to the two versions with
0 to 10 V and 4 to 20 mA outputs.
For all other versions the corre-
sponding values can be found in
➥ ➥ ➥ ➥ ➥ Value table 7-1 on page 8.

Check functionality

The functionality of the transducer
system and all its associated com-
ponents should be regularly
checked and recorded.
5.5

Fault conditions

When there is evidence that the
transducer system is not operating
properly, it should be taken out of
service and guarded against unau-
thorized use.
The buttons are automatically dis-
abled after approximately 10 min-
utes of non-use.
Advantages of this calibration

procedure:

The display will indicate the cur-
rent position value even during the
calibration procedure.
The last calibrated values remain
stored, regardless of whether the
programming mode was quite by
pressing the button or automati-
cally after 10 min.
