Set the calibration range using the keypad.
Value for 4 and 20 mA signal is set with actual input applied.
Adjust the output response speed of the 4 to 20 mA DC.
Enter integer value from 0 to 99 seconds.
Set the % of PV where the damping function is disabled.
When PV exceeds this value, the damping is disabled and
the output follows the PV.
Specify the value to be used as PV from: “Sensor1”,
“Terminal Temperature(Term)” and “Sensor1-Term”. The SV,
TV and 4V can also be specified and monitored from the
HART communicator or Integral Indicator.
The YTA320 variables include above plus: “Sensor2”,
“Sensor2-Term”, “Average” and “Differential temperature”.
When using differential value, select whichever is desired;
Sensor1-Sensor2 or Sensor2-Sensor1.
Specify input type.
Specify the number of wire for RTD or ohm input.
Select a unit from ° C, K, ° F, or ° R. (See note 1). This unit is
automatically referred as a PV, SV, TV or 4V unit when
Sensor1 is mapped.
Enable / disable sensor matching function. When it is set to
“enable”, sensor coefficient parameter can be entered.

R. (See note 1). This unit is
automatically referred as a PV, SV, TV or 4V unit when
Terminal Temperature is mapped.
Select CJC function
Specify constant value to be used for CJC function.
Specify input type.
Specify the number of wires.
Select a unit from
°
C, K,
°
F, or
°
R. (See note 1). This unit is
automatically referred as a PV, SV, TV or 4V unit when
Sensor2 is mapped.
Enable/disable sensor matching function. When it is set to
“enable”, sensor coefficient parameter can be set.

Enables/disables sensor back-up mode.
Shows the back-up status.
Enables the recovery from Sensor2 to sensor1 in back-up
operation.
