Installing the XM Electronic Overspeed Detection System 39
Other XM-220 Connections
The XM-220 module includes two 4-20mA outputs, a buffered output for
each input channel, and a DeviceNet™ connection that allows it to
communicate with a Programmable Logic Controller (PLC), Distributed
Control System (DCS) or another XM module. It can be connected to a
Startup switch as well. For more information about XM-220 module, refer to
the XM-220 Dual Speed Module User Guide.
Mounting the XM Modules The XM-442 mounts on the XM-946 terminal base unit, Cat. No. 1440-TB-G,
and the XM-220 mounts on the XM-941 terminal base unit, Cat. No.
1440-TB-B. We recommend that you mount the modules after you have
connected the wiring on the terminal base units.
ATTENTION
The XM-442 module is compatible only with the XM-946
terminal base unit. The keyswitch on the terminal base unit
should be at position 6 for the XM-442 module.
Do not attempt to install the XM-441 module on other
terminal base units.
Do not change the position of the keyswitch after
wiring the terminal base.
ATTENTION
The XM-220 module is compatible only with the XM-941
terminal base unit. The keyswitch on the terminal base unit
should be at position 4 for the XM-220 module.
Do not attempt to install XM-220 modules on other
terminal base units.
Do not change the position of the keyswitch after
wiring the terminal base.
ATTENTION
All XM modules are designed so you can remove and
insert them under power. However, when you remove or
insert the XM module with power applied, I/O attached to
the module can change states due to its input/output signal
changing conditions. Take special care when using this
feature.
