44 Configuration Parameters
Channel Transducer
Parameters The channel transducer parameters define the characteristics of the
transducers you will be using with the module. Use the parameters to
configure the transducer sensitivity, and operating range. There are two
instances of the channel transducer parameters, one for each channel.
TIP
The Channel LED will flash red when a transducer fault
condition exists on the channel even if you are not using
the channel. You can keep the Channel LED from flashing
red on unused channels by setting the unused 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.
Transducer 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. Unit. The sensitivity value is included with
the transducer’s documentation or it
may be imprinted on the side of the
transducer.
Eng. Units Defines the native units of the transducer. Options: mils
µm
Fault Low The minimum, or most negative, expected DC
voltage from the transducer. Volts
Note: A voltage reading outside this
range constitutes a transducer fault.
Fault High The maximum expected DC bias voltage from the
transducer.
Measured DC Bias (EDS File only) Shows the measured DC offset of the transducer
signal. This value is compared with Fault High and
Fault Low to determine whether the transducer is
working properly.
Transducer Status (EDS File only) States whether a transducer fault exists on the
associated channel. Possible status values: No Fault
