Configuring the XM EODS 51
1. In the XM-220 Speed Module Configuration Tool, click the Channel
tab. (The Channel tab is the default tab). You will see a screen similar to
this.
2. Enter or select the desired parameters to configure the operating mode,
and characteristics of the tachometer. This includes:
• Dual channel mode (two channels on the XM-220 measure two
independent speeds, usually on two separate components)
• the minimum and maximum expected DC voltage
• the DC bias time constant
• the number of tachometer signal pulses per revolution of the shaft
• the amount of hysteresis around the trigger threshold
• the multiplier value used by the internal tachometer signal to obtain
the measured speed
3. When you are finished, choose Device > Download to Device to
download your changes to the XM-220 module.
Select Dual channel parameter to
ensure proper operation of the
XM-220 in the XM EODS.
Check this checkbox to cause the XM-220
to provide a a small amount of current to
help detect transducer faults for passive
magnetic sensors.
A voltage reading outside this range
constitutes a transducer fault.
Enter zero if you are not using the tachometer
channel to disable the tachometer measurement.
Check this checkbox to enable Auto
Trigger mode. Uncheck this checkbox to
enable Manual Trigger mode and enter
Trigger threshold and Trigger slope.
TIP
Refer to Chapter 3 in the XM-220 Dual Speed
Module User Guide for a detailed description of the
configuration parameters.
