46 Configuration Parameters
Channel Parameters The Channel parameters define the characteristics of the transducers you will
be using with the XM-320. Use the parameters to configure the transducer
sensitivity, operating range, power requirements, measurement mode, and
calibration offset. There are two instances of the parameters, one for each
channel.
TIP
The Channel LED will flash red when a transducer fault
condition exists on a channel even if you are not using the
channel. You can keep the Channel LED from flashing red
on unused channels by setting the channel’s Fault High
and Fault Low to greater than zero and less than zero,
respectively. For example, set Fault High to +18 volts and
set Fault Low to -18 volts.
Channel Parameters
Parameter Name Description Values/Comments
Channel Name (XM Serial
Configuration Utility only) A descriptive name to help identify the channel in
the XM Serial Configuration Utility. Maximum 18 characters
Sensitivity The sensitivity of the transducer in millivolts per
Eng. Units. This value can be found on the
transducer’s data sheet.
Eng. Units Defines the native units of the transducer. Your
choice controls the list of possible selections
available in the Output Data Units parameter. It
also affects other module parameters, for example
the Alert and Danger Threshold, Measurement
Value, 4–20 mA Output. Options: mils (1/1000 inch)
mm (millimeter)
degrees
%
Output Data Unit The data units of the measured values. The available options depend on the
Eng. Units selection.
Fault High The maximum expected DC bias voltage from the
transducer. Volts
Note: A voltage reading outside this
range constitutes a transducer fault.
Fault Low The minimum, or most negative, expected DC bias
voltage from the transducer.
