Installing the XM-320 Position Module 29
Connecting the Setpoint Multiplication Switch
You can configure the module to multiply the alarm setpoints, or inhibit the
alarms during the start-up period. This can be used to avoid alarm conditions
that may occur during startup, for example, when the monitored machine
passes through a critical speed.
Wire the Setpoint Multiplication switch to the terminal base unit as shown in
Figure 2.16.

Connecting the 4-20mA Outputs
The module includes an isolated 4-20mA per channel output into a maximum
load of 600 ohms. The measurements that the 4-20mA output tracks and the
signal levels that correspond to the 4mA and 20mA are configurable. Refer
to 4-20mA Output Parameters on page 62 for a description of the 4-20mA
parameters.
Wire the 4-20mA outputs to the terminal base unit as shown in Figure 2.17.
ATTENTION
The Switch Input circuits are functionally isolated from
other circuits. It is recommended that the Switch RTN
signal be grounded at a signal point. Connect the Switch
RTN signal to the XM terminal base (Chassis terminal) or
directly to the DIN rail, or ground the signal at the switch
or other equipment that is wired to the switch.
