Connecting a Non-Contact Sensor
The Eccentricity module accepts input from any Allen-Bradley non-contact
eddy current probe. The figures below show the wiring of a non-contact eddy
probe to the terminal base unit.
Figure 2.17 Non-contact Sensor to Channel 1 Wiring
IMPORTANT
Figures 2.17 and 2.18 show the wiring to the XM-120
module revision D01 (and later). If you have an earlier
revision of the module, refer to Appendix D for wiring
information.
ATTENTION
You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. Recommended
practice is to ground the cable shield at the terminal base
and not at the transducer. Any convenient Chassis terminal
may be used (see Terminal Block Assignments on page 18).
IMPORTANT
The internal transducer power supply is providing power to
the non-contact sensor.
