Installing the XM-160/161/162 Direct Vibration Module 49
Connecting an IEPE Accelerometer and Non-Contact Sensor
Figure 2.44 shows the wiring of an IEPE accelerometer and a non-contact
sensor to the XM-162 terminal base unit.
IMPORTANT
The IEPE Power in the XM-160/161/162 module is
configurable in channel pairs: Channels 1 and 2, Channels 3
and 4, and Channels 5 and 6. When you have different
transducer types, such as an IEPE accelerometer and a
non-contact sensor, the non-IEPE powered transducers
cannot be in the channel-pair with the IEPE transducer.
For example, when you are connecting a single IEPE
accelerometer and a single non-contact sensor to the
XM-160/161/162, wire the accelerometer to channel 1 and
enable the IEPE Power Channels 1 and 2 parameter.
Wire the non-contact sensor to channel 3 and disable the
IEPE Power Channels 3 and 4 parameter.
Refer to IEPE Buffer Power and Signal Detection
Parameters on page 58 for more information on the IEPE
Power parameters.
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 17).
IMPORTANT
The XM-162 module provides an internal DC power
supply for powering a standard -24V non-contact eddy
current probe driver. The XM-160 and XM-161 modules
require a dedicated -24V dc power supply or an isolated
+24V dc power supply wired in reverse to power a
non-contact eddy current probe driver. Refer
to Connecting a Non-Contact Sensor to the XM-160 and
161 on page 33 for details.
