20 Installing the XM-720 Machine Monitor
The sensitivity, operating range, and power requirements have been predefined
in the provided configuration files. The characteristics of the transducer and
the signal processing performed on the input signals can be changed using the
XM Serial Configuration Utility. Refer to Transducer Parameters on page 44.
Setting the Buffer Range for the Transducer
The XM-720 provides buffered outputs of all transducer input signals through
the BNC connectors on the front panel.
The voltage operating range of the buffered outputs must be configured to
coincide with the corresponding transducer bias range. This operating range is
configured by placing a jumper from terminal 5 (channel 1) and terminal 22
(channel 2) to terminal 6 (Positive Buffer Bias) or terminal 21 (Buffer -) on the
XM-120/121/122 module, depending on the transducer. The buffered output
operating range is configured independently per channel.

IMPORTANT
The 1440-PK02-05M2 (gSE) monitor can measure both
"standard" vibration, similarly to the 1440-PK02-05M0,
and g’s Spike Energy™ (gSE). It can produce the gSE
measurement only with an IEPE accelerometer or
externally powered sensor.
