1 General instructions
The WAVESERIES signal conditioner PT 100 should only be
installed by qualified staff. The signal conditioner PT 100 should
only be powered up following professional installation.
2 Application
The WAVESERIES signal conditioner PT 100 can be used to
connect PT 100 sensors as well as converting temperature data
into standard linear current signals. The temperature range can
be set by DIP switches on the printed circuit board.
3 Mounting and dismounting
Warning!! Mounting and dismounting may only be carried out
16
when the power supply has be disconnected. Failure
to observe will lead to considerable damage!
3.1 Mounting onto TS 35 DIN rails
(s. Fig. 1)
3.2 Pluggable electronic components for range alteration
(depending on model)
(s. Fig. 2)
1. Remove connector, (depending on model either screw-type
or tension clamp).
2. Press locking clips on both sides of the enclosure.
3. Pull out the circuit board.
Warning!! The circuit board can only be inserted in one position.
The connectors have been coded by the manufacturer, ensuring that they cannot be reversed.
17
3.3 Setting the potentiometer (depending on model)
(s. Fig. 3)
The module has been exactly calibrated by the manufacturer.
Should nevertheless a follow-up adjustment be necessary, open
the hinged cover upwards.
The potentiometers are on the front panel.
3.4 Pluggable cross-connections for voltage supply
(s. Fig. 4)
A maximum feed through of 2 A is possible.
If a signal conditioner is accidently rotated through 180°, the
cross-connection cannot be inserted.
3.5 Labelling possibilities
(s. Fig. 5)
WS 10 connector markers can be used to label module.

4 Calibration
Warning!! The power supply must be disconnected, before
changing the signal conditioner settings using the
DIP switches.
Failure to observe will lead to considerable damage!
4.1 Equipment
– Power supply 24 Vdc, 50 mA
– Simulator for PT 100 or precision resistance decade
– Current meter/voltmeter that can be so calibrated, as to allow
an accuracy of > 0.1 % from the upper range value
4.2 Calibration with a signal output from 0 ... 20 mA
1. Select the temperature range on the printed circuit board
using the DIP switch, see table on the module or pages 22
and 23.
The DIP switches 1, 2 and 3 set the minimum input temperature ϑ
.
min
The span (difference between minimum and maximum input
temperature) is set using the DIP switches 4, 5 and 6.
19
2. Professionally install module.
3. Add 1 % of the temperature span to the selected "minimum"
temperature and set this value on a PT 100 simulator (when
using a precision resistance decade, where necessary observe DIN IEC 751 conversion table from °C to Ω!) and calibrate the signal conditioner output signal to 0.200 mA using
the null potentiometer. (The potentiometers are located behind the hinged cover).
4. Set the "maximum" selected temperature on a PT 100 simu-
lator (or precision resistance decade) and calibrate the signal
output to 20.000 mA using the Span potentiometer.
5. Repeat steps 3 and 4 (approx. 2-3 times), until the required
accuracy is achieved.
20
4.3 Calibration with an signal output from 4 ... 20 mA
1. Set the required temperature range on the printed circuit
board using the DIP switch, see table on the module or page
22 and 23.
The DIP switches 1, 2 and 3 set the minimum input temperature range ϑ
min
.
The span (difference between minimum and maximum input
temperature) is set using the DIP switches 4, 5 and 6.
2. Professionally install module.
3. Set the "minimum" selected value on a PT 100 simulator
(when using a precision resistance decade, where necessary
observe DIN IEC 751 conversion table from °C to Ω!) and set
the signal conditioners output signal to 4.000 mA with the aid
of the null potentiometer. (The potentiometers are to be found
behind the hinged cover)
4. Set the "maximum" selected temperature on a PT 100 simulator (or precision resistance decade) and calibrate the signal
output to 20.000 mA using the Span potentiometer.
5. Repeat steps 3 and 4 (approx. 2-3 times), until the required
accuracy is achieved.

4.4 Setting the DIP switches
Warning!! The signal conditioner PT 100 must be protected
against a direct electrostatic discharge when setting
the DIP switches.

Minimum input temperature: = -50 °C
Choose next lower or equal value according to table for ϑ
.
min
Table value -60 °C
Set DIP switch 1 to OFF; DIP switches 2 and 3
to ON.
The span is 200 K (150 °C - (-50 °C)).
The table value lies between 165 ... 245 °C
Set DIP switch 4 to OFF; DIP switches 5 and 6
to ON.
The input range must be raised by 10 K (-60 °C + 50 °C).
The 10 K corresponds to 5 % of the span (see calculation).
The input range can be raised by up to 25 % using the "null"
potentiometer.
Calculation:
Should the 25 % be exceeded using the above calculation, then
an adjustment to the temperature input range is not possible.
