3.2.2 Sensor settings
When changing sensor type, it is necessary to
change the parameters related to each sensor.
Figure 3.1 shows both the wire connection to
input terminals of the transmitter, and sensor
type selection for parameters in each connection
case. Note that thermocouples and voltage value
input are categorized as Group A, and resistance
temperature detectors and resistance are
categorized as Group B. Check the connection
between input terminals and temperature sensors,
and set the correct sensor type and the number
of wire connections in “Sensor1” or “Sensor2” (for
2-input model).
The following shows the standard setup.
(1) Setting the sensor type
Set a sensor type using the following parameters.

NOTE
If a sensor of Group A is used, the number of
wire connections is automatically changed to
“2 WIRE”. In such a case, it is not necessary
to “set the number of wire connections” of Item
(2) below. If “No connection” is set, a number of
wire connections can be set, however, it is made
invalid.
(2) Setting the number of wire connections
Set a number of wire connections using the
following parameters. However, this setup is only
required when the Group of the sensor type is “B”.
This setup is not required for a sensor of Group A.

NOTE
If “4 WIRE” is selected as the number of wire
connections of Sensor1, Sensor2 cannot be used
even for a 2-input model temperature transmitter.
Therefore, the sensor type at Sensor2 side is
changed to “No connection” automatically.
