Figure 2.25 IEPE Accelerometer and Non-Contact Sensor Wiring
Connecting Two Accelerometers and a Non-Contact Sensor
Figure 2.26 shows the wiring of two IEPE accelerometers and a non-contact
sensor to the terminal base unit of the XM-123. The IEPE accelerometers are
wired to channel 1 and channel 2. The non-contact sensor is wired to the
tachometer input signal.
IMPORTANT
A jumper from terminal 5 to terminal 6 is required for
channel 1 buffered output. A jumper from terminal 22 to
terminal 21 is required for channel 2 buffered output. Refer
to Configuring Buffered Output Input Range on page 27.

Jumpering terminal 21 to terminal 22

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 XM-123
terminal base and not at the transducer. Any convenient
Chassis terminal may be used (see Terminal Block
Assignments on page 18).
