Chapter 1 Install the XM-124 Standard Dynamic Measurement Module
Connect the Tachometer Signal
The XM-124 module provides a single tachometer input signal. The signal
processing performed on the tachometer signal depends on the configuration of
the module. See
page 78 for a description of the tachometer parameters.
Connecting a Magnetic Pickup Tachometer
Figure 12 shows the wiring of a magnetic pickup tachometer to the terminal base
unit.

Connecting a Hall Effect Tachometer Sensor
Figure 13 shows the wiring of a Hall Effect Tachometer Sensor, catalog number
44395, to the terminal base unit.

IMPORTANT If you are not using the tachometer input, set the Pulses per Revolution
parameter to zero (0). This disables the tachometer measurement and
prevents the module from indicating a tachometer fault (TACH indicator
flashing yellow). A tachometer fault occurs when no signal pulses are
received on the tachometer input signal for a relatively long period.
