WAVESERIES PT 100/4 Signal Conditioners for Current Output Type Screw-type connection WTS4 PT100/4 Select C Tension clamp connection WTZ4 PT100/4 Select C Cat. No. 843227 843228 Read these instructions before using the product and retain for future information.
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 boar d.
.2 Pluggable electronic components for range alteration (depending on model) (Figure 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 boar d. Warning!! The circuit boar d can only be inserted in one position. The connectors have been coded by the manufactur er, ensuring that they cannot be reversed. 3.
3.4 Pluggable cross-connections for voltage supply (Figure 4) A maximum feed through of 2 A is possible. If a signal conditioner is accidently rotated thr ough 180°, the cross-connection cannot be inserted. 3.5 Labelling possibilities Figur e 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. Failur e to observe will lead to considerable damage! 4.
4.2 Basic 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 41 and 42. The DIP switches 1, 2 and 3 set the minimum input temperature ϑmin. The span (difference between minimum and maximum input temperature) is set using the DIP switches 4, 5 and 6. 2. Professionally install module. 3.
Example Input range: -50 ... +150 °C Minimum input temperature: = -50 °C Choose next lower or equal value according to table for ϑmin. 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).
4.3 Linearity calibration 1. Proceed with basic calibration, see above. 2. Add 1 % of the temperature span to the selected " minimum" temperature and set this value on a PT 100 simulator (when using a precision r esistance 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. 3. Set the mean temperatur e "(ϑmax + ϑmin)/2" on a PT 100 simulator.
Example Chosen measurement -50 ... +150 °C → 200 K span range: 1 % from 200 K span = 2 K Set minimum temperature -50 °C + 2 K = -48 °C on the PT 100 simulator and calibrate the signal conditioner output signal to 0.200 mA using the null potentiometer . Mean temperatur e = (ϑmax + ϑmin)/2 = (150 °C + (-50 °C))/2 = 50 °C Set the 50 °C value on a PT 100 simulator Then determine ∆I: ∆I = measured value from measuring instrument - 10.000 mA → ∆I = 9.940 mA - 10.000 mA = -0.
4.4 Basic calibration with an output signal from 4 ... 20 mA 1. Set the r equired temperature range on the printed circuit board using the DIP switch, see the table on the module or sides 41 and 42. The DIP switches 1, 2 and 3 set the minimum input temperature ϑmin. The span (dif ference between minimum and maximum input temperature) is set using the DIP switches 4, 5 and 6. 2. Professionally install module. 3.
Example Input range: -50 ... +150 °C Minimum input temperature: = -50 °C Choose next lower or equal value according to table for ϑmin. 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 correspond to 5 % of the span (see calculation).
4.5 Linearity calibration 1. Carry out a basic calibration, see above. 2. Set the selected " minimum" temperatur e on a PT 100 simulator (when using a pr ecision r esistance decade, wher e necessary observe DIN IEC 751 conversion table from °C to Ω !) and calibrate the signal conditioner output signal to 4.000 mA using the null potentiometer . 3. Set the mean temperature "(ϑmax + ϑmin)/2" on a PT 100 simulator. Determine the difference to the desired value: "∆I = shown value on measuring instrument - 12.
Example Chosen measuring range: -50 ... +150 °C Set minimum temperature (-50 °C) on the PT 100 simulator and calibrate the signal conditioner output signal to 4.000 mA using the null potentiometer . Mean temperatur e = (ϑmax + ϑmin)/2 = (150 °C + (-50 °C))/2 = 50 °C Set the 50 °C value on the PT 100 simulator Then determine ∆I: ∆I = measured value from measuring instrument - 12.000 mA → ∆I = 11.940 mA - 12.000 mA = -0.060 mA Then calibrate the output signal to (12.
4.6 Setting the DIP switches Warning!! The signal conditioner PT 100 must be protected against a direct electrostatic discharge when setting the DIP switches.
