5.6.4 Parameters of Transducer Block
The transducer block makes settings for the
temperature transmitter-specific functions of the
YTA320, such as the temperature input and display
settings. See Appendix 1 for a list of all parameters
of the YTA320; this section describes only the
settings for important parameters.
Note that you can choose “˚C” or “Kelvin” as the unit
of temperature. “˚F” or “˚R” can also be selected for
a model with the option code /D2.
 Mode Setting Parameter
MODE_BLK
Supports O/S and Auto modes. In the O/S
mode, the transducer block does not function,
as implied by the mode name “Out of Service.”
 Parameters Related to Sensor Input
The number “2” enclosed in parentheses
appearing in the following parameter names
and descriptions indicates that the preceding
number “1” should be read as “2” for the cases
of sensor 2, respectively.
SENSOR_TYPE_1 (2)
Shows and stipulates the type of sensor
connected to sensor input 1 (or 2). The
following sensors can be connected.
· Thermocouple:
Types B, E, J, K, N, R, S, and T (IEC584),
types L and U (DIN43710), and Types W3
and W5 (ASTM E-988)
· 2-/3-/4-wire RTD:
Pt100, Pt200, Pt500 (IEC751) JPt100
(JIS), Ni120, Cu (SAMARC21-4)
· 2-/3-/4-wire resistance input
· 2-wire DC mV input
IMPORTANT
Whenever 4-wire input is specified for Sensor 1,
set ‘Non Connection’ for Sensor 2.
4-wire input cannot be used as Sensor 2.
SENSOR_CONNECTION_1 (2)
Shows and stipulates the number of wires
connected to sensor input 1 (or 2). This setting
only valid for RTD and resistance input.
PRIMARY_VALUE_1 (2)
Shows the value and status of the input from
sensor 1 (or 2). The unit set in PRIMARY_
VALUE_RANGE_1 (or ..._2) applies to the unit
of the value. The damping time constant is set
in PRIMARY_VALUE_FTIME_1 (or ..._2).
NOTE
If an input exceeds the range shown in PRIMAR
Y_VALUE_RANGE_1(2), the value up to 120%
of the range will be output for upper limit side,
and -20% of the range will be output for lower
limit side. In thie case, the accuracy of the input
exceeding the range shall not be guaranteed.
SECONDARY_VALU
Shows the value and status of the terminal
board temperature. The unit of temperature
is set in SECONDARY_VALUE_UNIT, and
the damping time constant in SECONDARY_
VALUE_FTIME.
DIFFERENTIAL_VALUE
Shows the value and status of the difference
between 2 inputs [sensor 1 input value minus
sensor 2 input value] when 2 sensors are
connected. The unit of temperature is set in
DIFFERENTIAL_UNIT, and the damping time
constant in DIFFERENTIAL_VALUE_FTIME.
When there is no connection to sensor 2 input,
the status of DIFFERENTIAL_VALUE is Bad
and the value is undefined.
AVERAGE_VALUE
Shows the value and status of the average of
2 inputs when 2 sensors are connected. The
unit of temperature is set in AVERAGE_UNIT,
and the damping time constant in AVERAGE_
VALUE_FTIME. When there is no connection
to sensor 2 input, the status of AVERAGE_
VALUE is Bad and the value is undefined.
BACKUP_VALUE
When 2 sensors are connected, this parameter
normally shows the value input from sensor
1, and in case of burnout of sensor 1 (when
the backup action becomes active), shows
the value input from sensor 2. The unit and
damping time constant follow the respective
settings for the input currently selected.
