3. OPERATION
3. OPERATION
IMPORTANT
Do not turn off the power to the transmitter
immediately after setting the data using the
BT200. If the transmitter is turned off less than
30 seconds after parameters have been set, the
setting data will not be stored in the transmitter.
3.1 Parameters Description
The following outlines the function of the BRAIN
parameters for the YTA.
• Sensor configuration See Page 3-4
When changing the sensor type from the current
setting to another, it is necessary to change param-
eter settings.
D10: SENSOR1 TYPE ............. Sensor type setting
D20: SENSOR1 WIRE ............. Wire connections setting
E10: SENSOR2 TYPE(YTA320 only)
E20: SENSOR2 WIRE(YTA320 only)
• Process variable mapping See Page 3-5
Process variables can be assigned as the primary
variable(PV), the secondary variable(SV), the
tertiary variable(TV), and the quaternary
variable(4V).
The following items can be mapped as the process
variables.
Sensor1, Sensor2* 2 , DIFFERENCE* 2 , AVERAGE* 2 ,
Sensor1-Term, Sensor2-Term* 2 , Terminal Temp (* 2 :
These items are displayed for the model YTA320 only.)
B10: PV is, B20: SV is, B30: TV is, B40: 4V is
• Unit setting See Page 3-6
Choose the engineering unit for the process
variables assigned as the PV, SV, TV, and 4V from
degree C and Kelvin. When mV or ohm is specified
as an input type, the unit is automatically set to mV
or ohm.
B11: PV UNIT, B21: SV UNIT, B31: TV UNIT, B41: 4V
UNIT
• Range setting See Page 3-6
Changing the range of the PV as a 4 to 20mA DC
output. There are two ways to set the range value.
F10: LRV , F20: URV ....................... Setting by keypad
F30: AUTO LRV , F35: AUTO URV .
......................... Setting by applying value
• Damping time constant setting See Page 3-6
Setting the response time of the transmitter smooths
the output with rapid changes in input.
The damping time constant can be set between 1
and 99 seconds.
B12: PV DAMPING, B22: SV DAMPING, B32: TV
DAMPING, B42: 4V DAMPING

C10: TAG NO. ............... Tag number (16 characters)
O10: MEMO1, O20: MEMO2
...... MEMO (16 characters)
O30: DESCRIPTOR ...... DESCRIPTION (16 characters)
O40: DATE ..................... DATE (6 characters)
• Forced Output Function
(Manual Output mode) See Page 3-7
Setting the transmitter to output a fixed current
from -2.5 to 110 % in 0.1% increments for loop
checks.
G10: OUTPUT MODE, G20: OUPUT VALUE
• Integral Indicator Display Function
See Page 3-7
The input and output values can be displayed, as
can the type of temperature sensor and the number
of wire connections.
M10: PROCESS DISP ...... Process variable display
selection
M20: %/mA DISP ................ Output display selection
M30: MATRIX DISP ............ Sensor type/wire connec-
tions display selection
M40: BAR GRAPH .............. Output bar graph display
setting
M50: DISP UPDATE ........... Selection of a cycle speed
for display
M55: Err- NO DISP ............. Error code display
• Burn Out Function See Page 3-10
Configure the current output value in sensor failure.
Selectable from High, Low, and User setting
values.
F40: BURN OUT, F41: BURN OUT VAL, F50: TX
FAILURE
• Reverse Output Function See Page 3-10
To reverse the direction for a 4 to 20 mA DC
output relative to input.
H10: REVERSE OUT
