Connecting Two Accelerometers and a Non-Contact Sensor

Figure D.8 shows the wiring of two IEPE accelerometers and a non-contact
sensor to an earlier revision of the XM-122 module (before revision D01). 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 MODEL 580 VIBRATION PICKUP

TO XM-122 VIBRATION MODULE CHANNEL 2

Cable shield not
connected at this end

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
179).

IMPORTANT

The buffered outputs are valid for all signals in this wiring
scheme.
