1719 Ex I/O Installation Instructions
Pt100 Short Circuit
1. Short circuit the Pt100 sensor.
2. Monitor the tag for the I/O module and make a note of the measured value.
3. In the Add-on Profile, using the Ch0x dialog, set the measuring input of the I/O module to 2-wire measurement with a Pt100 sensor.
4. Enter the measured resistance in the Wire Resistance field. The maximum permissible wire resistance is 50 Ω.
For more information, see the Add-on Profile help topic for the 1719-IR4B module.
Use a Calibrating Resistor
1. Use a calibrating terminal with an integrated calibrating resistor in the sensor supply line.
2. In the Add-on Profile, using the Ch0x dialog, set the measuring input of the I/O module to 2-wire measurement with a Pt100 sensor.
3. In the Add-on Profile, set the wire resistance to 20 Ω.
4. Replace the Pt100 sensor at the measuring point with a 100-Ω measurement resistor.
5. To measure the resistance, monitor the tag for the I/O module.
6. Set the displayed value to 0 C using the calibration potentiometer.
7. Then reconnect the Pt100 sensor.
For more information, see the Add-on Profile help topic for the 1719-IR4B module.

Interference
Electromagnetic fields can interfere with the communication path.
WARNING: Risk of explosion
• Observe the wiring specifications set out in IEC 60079-14 or NEC 500-510 for wiring in Zone 2 or Division 2. Only connect or disconnect EtherNet/IP™ and
power cables when the area is safe.
• Accessories that do not meet the requirements for use in hazardous areas can cause explosive mixtures to ignite.
• Only use accessories and devices that are approved for use in the respective environment.
