Operating Procedure
Operating Procedure
You can register Dummy Sensors so that you do not need to change I/O assignments even if the number
of Sensor Amplifier Units changes. Explicit messages are also used to register Dummy Sensors.

Description
1
Mounting the Sensor
Communications Unit to
the DIN Track
Mount the Unit to the DIN Track. Mount the Sensor Amplifier Units to the
DIN Track and then link them together.
Refer to Installation on page 30 in Section 2 Installation and Connections.
To remove the Unit from the DIN Track, slide it on the DIN Track to
disconnect it from the adjacent Units and then remove it from the
DIN Track.
2
Connecting Sensor
Amplifier Units to the
Sensor Communications
Unit
Slide the Sensor Communications Unit, align the clips on the edge, and
press it onto the Sensor Amplifier Unit until you hear it lock into place.
Refer to Installation on page 30 in Section 2 Installation and Connections.
