Figure 26 - Two IEPE Accelerometers and a Non-contact Sensor Wiring
Connect a Velocity Sensor and Two Non-contact Sensors
Figure 28 shows the wiring of a velocity sensor and two non-contact sensors to
the terminal base unit. The velocity sensor is wired to channel 1. The first non-
contact sensor is wired to channel 2, and the other non-contact sensor is wired
to the tachometer input signal.
IMPORTANT Transducer DC bias is monitored on all signals.

TYPICAL WIRING FOR TWO IFPF ACCELEROMETERS AND
NON-CONTACT SENSOR TO XM-124 STANDARD DYNAMIC MEASUREMENT MODULE
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 28 .
IMPORTANT Transducer DC bias is monitored on all signals.
