Installing the XM-720 Machine Monitor 21
IMPORTANT
By default, both buffered outputs have been wired for a
positive bias transducer (accelerometer and powered
sensor). This means that orange jumper wires have been
supplied on the XM-120/121/122 terminal block between
terminals 5, 6, and 22 (see Figure 2.9).
Figure 2.9 Jumpers for buffer input wiring
If the transducer is not a positive bias transducer, follow
these guidelines:
• For a non-contact sensor, remove the orange jumper
between terminals 5 and 6 (terminals 22 and 6 for
channel 2) and install it between terminals 5 and 21
(terminals 22 and 21 for channel 2).
• For a non-bias sensor, such as a velocity sensor, remove
the orange jumper between terminals 5 and 6 (terminals
22 and 6 for channel 2).
Refer to Table 2.3 for details. Refer to the XM Users Guide
for more information about the XM-120/121/122 module.
