Installing the XM-122 gSE Vibration Module 39
Connecting Two Accelerometers and a Non-Contact Sensor
Figure 2.28 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.
ATTENTION
Figure 2.28 shows the wiring to the XM-122 module
revision D01 (and later). If you have any earlier revision of
the module, refer to Appendix D for wiring information.
ATTENTION
You may ground the cable shield to 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
Make certain the IEPE Power parameter is enabled for
both channel and channel so power is provided to the
accelerometers. Refer to Channel Transducer Parameters
on page 58.
IMPORTANT
Transducer DC bias is monitored on all signals.
IMPORTANT
A jumper from terminal 5 to terminal 6 is required for
channel 1 buffered output. A jumper from terminal 22 to
terminal 6 is required for channel 2 buffered output. Refer
to Configuring Buffered Output Input Range on page 28.
