Figure 25 - IEPE Accelerometer and Non-contact Sensor Wiring
Connect Two Accelerometers and a Non-Contact Sensor
Figure 27 shows the wiring of two IEPE accelerometers and a non-contact
sensor to the terminal base. The IEPE accelerometers are wired to channel 1
and channel 2. The non-contact sensor is wired to the tachometer input signal.

TYPICAL WIRING FOR IFPF ACCELEROMETER AND NON-CONTACT
SENSOR TO XM-124 STANDARD DYNAMIC MEASUREMENT MODULE
WARNING: Explosion Hazard. 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 28 ).
IMPORTANT Verify the Transducer Power Type parameter is set to IEPE for both
channel 1 and channel 2 so power is provided to the accelerometers.
See Transducer Object (Class ID 328H) on page 158 . (This setting also sets
the buffered output to the 0 Volt to 24 Volt range.)
