3.4 Basic Setup
3.4.1 Sensor Configuration
When changing sensor type, it is necessary to
change the parameters related to the sensor type.
Figure 3.1 shows the wire connections to the
input terminals of the transmitter and sensor type
selections for the parameters in each connection
case. Note that TCs and mV are categorized as
Group A and RTDs and ohm are as Group B.
Check the connections between the input terminals
and temperature sensors and set the correct sensor
type and the number of wire connections for the
parameters.
The setting method is as described below.
(1) Selecting the sensor type/Setting the
number of wires
• Procedure to call up the display
Device setup → Basic setup → Sensor Basic
Setup → Sensor1 Basic Setup → set Sns1
Probe (M)
Set the sensor probe type and set the number
of wires according to the message on display.
(2) Setting the sensor unit
Set the sensor unit.
• Procedure to call up the display
Device setup → Basic setup → Sensor Basic
Setup → Sensor1 Basic Setup → Sensor1
Others → Sns1 Unit
NOTE
In case of 3 wire RTD or ohm connection, if
actual connection and connection setting is
imbalance, unforeseen alarm may be generated.
3.4.2 Process Variable Mapping
Process variable can be assigned as primary
(PV), secondary (SV), tertiary (TV) or fourth (QV)
variable and can be monitored on Integral indicator
or Handheld terminal. The primary variable (PV)
is output as a 4 to 20mA analog signal, and thus
it is necessary to map the variable as PV. Other
variable can be left as “Terminal” when they are not
required. Configuration of Sensor 1 (and Sensor 2)
must be done before changing the process variable
mapping. (See 3.4.1)
Call up the “Device Variables” display and carry out
the process variable mapping to PV, SV, TV, and
QV.
• Procedure to call up the display
Device setup → Process variables → Dynamic
Variables → PV (SV, TV or QV) → PV (SV, TV
or QV) is
Set process variables below.
Sensor1: Sensor1 input
Sensor1-Terminal: Temperature difference
between sensor1 input and terminal
temperature
Terminal: Terminal temperature
Sensor2: Sensor2 input
Sensor2-Terminal: Temperature difference
between sensor2 input and terminal
temperature
Sensor1-Sensor2: Difference between sensor1
input and sensor2 input
Sensor2-Sensor1: Difference between sensor2
input and sensor1 input
Average: Average of sensor1 input and sensor2
input
