28 Installing the Absolute Shaft Module
The case mounted vibration sensor must be connected to channel 2. The
Absolute Shaft module supports the following Allen-Bradley 9000 series
sensors.
Important Considerations
When mounting the vibration sensor and the non-contact eddy current probe,
it is important to note the following:
• The two sensors should be mounted at or adjacent to each machine
bearing.
• The sensors should be mounted in the same geometric plane.
• It is preferable to mount the transducers at the same point on the same
bearing half. This can be done by using a dual mounting housing (such
as the Dual Probe Holder, Cat. No. EK-29000-DPH01). The positions
chosen should be the same at each bearing.
Connecting a Non-Contact Sensor and 9000 Series Sensor
The following figure shows the wiring of a non-contact sensor and a 9000
series sensor to the terminal base unit. The non-contact sensor must be wired
to channel 1 and the 9000 sensor must be wired to channel 2.

Cat. No. Model
EK-43781I 9000A General Purpose Sensor
EK-43808I 9100VO Velocity Output Sensor
EK-43786I 9100CSA General Purpose Sensor
EK-43805I 9100T High Temperature Sensor
IMPORTANT
The Absolute Shaft module requires the XM-121 module
revision B01 (and later). Earlier revisions of the module do
not support the Absolute Shaft wiring configuration.
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.
