1. INTRODUCTION

Thank you for purchasing the YTA series Temperature Transmitter.

The YTA temperature transmitter is fully factory-tested according to the specifications indicated on your order.

This manual describes BRAIN communication functions of the model YTA110, YTA310, and YTA320 temperature transmitters and the various settings for temperature transmitter functions that can be set via the BT200 handheld terminal. The BT200 BRAIN terminal is required to change the settings of internal transmitter parameters.

In order for the YTA temperature transmitter to be fully functional and to operate in an efficient manner, read the instruction manual carefully to become familiar with the functions and operation as well as handling.

See User’s Manual IM 01C00A11-01E for details related to using the BT200 BRAIN terminal. For details of mounting, wiring and maintenance of this transmitter, see the separate User’s Manual IM 01C50B01-01E.

2. CONDITIONS OF COMMUNICATION LINE

2. CONDITIONS OF COMMUNICATION

LINE

2.1 Interconnection Between YTA

and BT200

WARNING

Do not attempt to use the BT200 in a dangerous environment where explosive gas or inflammable vapor is generated.

The BRAIN communication signal is superimposed onto the 4 to 20 mA DC analog signal. Since the modulated wave is a communication signal, superimposing it on the normal signal will, from basic principles, cause no error in the DC component of the analog signal. Thus, monitoring can be performed via the BT200 while the transmitter is on-line.

As shown in Figure 2.1, there are two methods of connecting the transmitter and the BT200: the first is to use the BT200 connection hook provided in the terminal box and the other is to use a terminal board or relay terminals on the transmission line.

Load impedance : 3.3 mH or less Communication distance: 2 km (1.25 mile), when

CEV cable is used

Distance from the power line:

Output signal line : 15 cm (5.9 inch) or more

(do not use parallel wiring)

Input signal line : 100 cm (39.8 inch) or more

(do not use parallel wiring)

Input impedance of receiver connected to receiving resistor: 10 kΩ more (at 2.4 kHz)

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.

3.2.2 Process Variables Mapping

Process variable mapping;

B10: PV is, B20: SV is, B30: TV is, B40: 4V is

Process variables can be assigned as the primary variable(PV), the secondary variable(SV), the tertiary variable(TV), and the quaternary variable(4V). The PV always outputs a 4 to 20mA DC analog signal corresponding to Lower Range Value and Upper Range Value. Mapping process variables to the SV, TV, and 4V is optional.

The following items can be mapped as the process variables.

Sensor1 : Sensor1 input value. Sensor2 : Sensor2 input value. DIFFERENCE

*1,*2,*4

: Difference between

Sensor1 and Sensor2.

(Sensor1-Sensor2 or

Sensor2-Sensor1; specified in B05: SET DIFF)

AVERAGE

*1,*4

: Average of Sensor1 and Sensor2. [(Sensor1 + Sensor2)/2]

Sensor1-Term

*4,*5

: Difference between

Sensor1 and terminal temperature

Sensor2-Term

*1,*4,*5

: Difference between

Sensor2 and terminal

temperature Terminal Temp : Terminal temperature Not used

: Showing that a process

variable is not assigned.

*1: This item is displayed only when the YTA320 2-input

temperature transmitter is used. *2: The setting in B05 applies to the PV, SV, TV, and 4V. *3: “Not used” is not displayed for B10 since the PV

requires process variable mapping. *4: When this item is selected, the sensor types to be set

for D10(Sensor1) and E10(Sensor2) should be

selected from any one of the following three groups;

Temperature sensor(T/C and RTD), DC voltage or

resistance. The combination(for example, temperature

sensor and DC voltage input) would cause an incorrect

computation due to the different unit system and is not

allowed. *5: When this item is selected, DC voltage and resistance

input should not be set for D10(Sensor1) or

E10(Sensor2).

● Example: Use two temperature sensors to map the difference (Sensor2-Sensor1) between Sensor1 and Sensor2 to the PV (the primary variable). Before mapping the process variable, complete the setting of the temperature sensor to be connected to Sensor1 and Sensor2.

Sensor1 setting: D10: SENSOR1 TYPE, D20:

3.2.3 Unit Setting

B11: PV UNIT, B21: SV UNIT, B31: TV UNIT, B41: 4V UNIT

Select the engineering unit for the process variables assigned as PV, SV, TV, and 4V from degree C, Kelvin, degree F* and degree R*. When mV or ohm is specified as an input type, the unit is automatically set to mV or ohms.

*: Degree F and degree R are available only when

optional code /D2 is specified.

3.2.4 Range Setting

(a) Changing the range with keypad

Lower range value setting;

F10: LRV, Upper range value setting; F20: URV

The range for the PV corresponding to the 4 to 20mA output signal is set at the factory before shipment. The procedure to rerange is as follows.

● Example: Changing the measurement range from 0 to 100°C to 0 to 150°C .

PARAM F10:LRV 0 degC F20:URV 100 degC F30:AUTO LRV DISABLE

DATA DIAG PRNT ESC

PARAM F20:URV 0 degC + 150

DEL CLR ESC

Note : The unit selected in B11: PV UNIT is applied to the units used

for F10 and F20.

NOTE

When entering numeric values at the range setting, the value of URV must be greater than that of LRV. Range Setting Condition: URV > LRV

1. Select F20: URV and press [ENTER].

2. Input “150” and press [ENTER] twice.

3. Press [OK].

3.2.5 Setting Damping Time Constant

B12: PV DAMPING, B22: SV DAMPING, B32: TV DAMPING, B42: 4V DAMPING

Setting the response time of each Process Variable to make the output change very slowly with a rapid change in input. Set the value from 0 to 99 seconds.

If the time constant is set to 2 seconds, the transmitter calculates a reading every cycle using the damping equation, in order to make the output 63 percent of the input range after 2 seconds.

This damping time constant is normally set to work when the temperature make a step change within 2 percent of the output range. The damping can be changed using the “B13: PV DMP POINT” parameter.

● Setting Damping Holding Point

B13: PV DMP POINT

This parameter is used to set the point where the transmitter conducts the PV damping operation, depending on a magnitude of the change in the input value. When the change value in percent exceeds the setting value, the transmitter outputs the signal without the damping operation. Set the value as a percent of span.

● Example: Output pattern for the setting value of 10%
