1) Setting the Sensor Type
■ Procedure to call up the sensor type setting
parameter (Lin Type)
AI1/AI2 block: Lin Type
Set the sensor type.
■ Procedure to call up the sensor type information
parameter (Sensor Range)
AI1/AI2 block: Sensor Range : EU at 0%
AI1/AI2 block: Sensor Range : EU at 100%
Displays the lower and upper limit values that
can be measured by the sensor type set in the
sensor type setting parameter (Lin Type) as the
lower limit information parameter (EU at 0%)
and the upper limit information parameter (EU
at 100%).
2) Setting the Temperature Sensor
Connection
This is set when using the resistance temperature
sensor.
■ Procedure to call up the connection setting
parameter (Sensor Connection)
AI1 block: Sensor Connection
Select and set any of the 2-, 3-, or 4-wire
methods corresponding to the resistance
temperature sensor.
AI2 block: Sensor Connection
Select and set either 2- or 3-wire methods
corresponding to the resistance temperature
sensor.
NOTE
In 4-wire connection, first set "Not Used" to AI2:
Lin Type, then set the AI1: Lin Type/Sensor
Connection.
3) Setting the Cold Junction Compensation
(CJC) of the Thermocouple Sensor
This is set when using the thermocouple sensor.
■ Procedure to call up CJC function
parameter(Selection of Reference Junction)
AI1/AI2 block: Selection of Reference Junction
Select the CJC function.
To calibrate voltage for the thermocouple
input, set the cold junction temperature to No
Reference (0).
■ Procedure to call up external temperature
Compensation parameter(External Reference
Junction Value)
AI1/AI2 block: External Reference Junction
Value
In the CJC function parameter (Selection
of Reference Junction), the cold junction
temperature value of the thermocouple is
selected the external (2), set the external
compensation temperature.
The CJC is also called reference junction
compensation.
IMPORTANT
Setting the sensor type automatically resets the
zero-gain adjustment value to the factory setting.
7.3.10 Assignment to AI Object
Output of the process value via field wireless
network is set by AI1/AI2 block.
Either actual target value or % value of the
temperature, the voltage, and resistance is set as
the output of process value from the AI1/AI2 block.
7.3.11 Burnout Setting
Specify the direction of PV value at the burnout.
• AI1/AI2 block: Burn Out Type
Enable Hard Switch: the direction specified by
hardware switch
Up: Higher side
Down: Lower side
Selecting Up and Down disables the setting of
hardware switch
7.3.12 Write Protect
Hardware write protection and software write
protection functions are available for this
transmitter.
1) Procedure to call up the protection setting
parameter (UAP Option)
The following settings can be configured in the
UAP Option parameter.
- Setting to enable or disable software write
protection.
- Setting to enable or disable the hardware write
protection switch.
