Figure 27 - Two IEPE Accelerometers and a Non-contact Sensor Wiring
Connect a Velocity Sensor and Two Non-contact Sensors
The following figure 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 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.
See Connect the Buffered Outputs on page 33 .

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 27 ).
