3. First turn on the 24 volt power supply for the transmitter, and then turn on the BT200 Brain Terminal by pressing the [ON/OFF] key. The brain terminal runs through a self-test, and then comes up in the initial data panel. From the initial data panel, you can access the main menu panel by pressing the [F4] key. Please see pages 4-6 to 4-12 of the BT200 Brain Terminal manual for the basic operations of the terminal.
To become familiar with moving around the menu structure of the BT200 Brain Terminal, follow the procedure as outlined on pages 4-6 to 4-13 of the BT200 Brain Terminal manual, “BASIC OPERATIONS”. Note that these pages are for connection to a pressure transmitter, but the menus for the temperature transmitter are quite similar.
4. Configure the YT200 Smart Temperature Transmitter for the following:
(B20) Input Type = type J thermocouple
(B21) Unit = *C
(B22) Lower Range Value = 0*C
(B23) Upper Range Value = 80100*C
(B30) Damping Time = 1 second
(B40) Display Select = user set
(C40) RJC setting = on
Note all of the above changes to the configuration are "output-related information" elements. The communication block diagram and parameter summary are the only references provided by the manufacturer, these are on pages 23 to 26 of the YT200 manual.
Note don't bother changing the non-output related information at this time... these elements do not directly affect the transmitter output, so we will ignore this information for the time being!
5. Quickly verify the configuration by measuring the temperature of each bath with a thermometer and the YT200 Temperature Transmitter. Record all required information in table 1. (Note, reference temperature measurement is the glass thermometer ... don't forget about the correction factor!)
Note, it is possible to display the temperature and transmitter output (as measured by the transmitter) on the brain terminal display. Go to the main menu panel, then select option A, “DISPLAY”. Temperature and transmitter output are updated once every 6 seconds.
Note, for table 1, error is to be calculated based on the C calculated from loop current.
6. It is possible to set the transmitter to fail up or down via software configuration. Refer to the block diagram and parameter summary on pages 24 to 26 of the YT200 manual, then configure the transmitter for upscale burnout. To verify upscale burnout, simulate thermocouple burnout by disconnecting one of the thermocouple wires from the transmitter, then observe the transmitter output signal as indicated by the DMM. Record your observations
7. Configure the transmitter for downscale burnout. To verify downscale burnout, simulate thermocouple burnout by disconnecting one of the thermocouple wires from the transmitter, then observe the transmitter output signal as indicated by the DMM. Record your observations
8. Disconnect the thermocouple from the transmitter, then connect a 3-wire, 100 ohm ice point platinum RTD (European alpha) to the transmitter. Follow the directions given on page 20 of the YT200 manual.
9. Configure the 3044C Smart Temperature Transmitter for a 3-wire RTD. Other information as follows:
(B20) Input Type = 100 ohm ice point platinum RTD,
European alpha, 3-wire
(B21) Unit = *C
(B22) Lower Range Value = 0*C
(B23) Upper Range Value = 100*C
(B30) Damping Time = 1.0 seconds
(B40) Display Select = user set
Refer to the directions given in step 4.
10 Quickly verify the configuration by measuring the temperature of each bath with a thermometer and the YT200 Temperature Transmitter. Record all required information in table 2. (Note, reference temperature measurement is the glass thermometer ... don't forget about the correction factor!)
Note, for table 2, error is to be calculated based on the C calculated from loop current.
11. Please note again that it is possible to set the transmitter to fail up or down via software configuration. Refer to the block diagram and parameter summary on pages 24 to 26 of the YT200 manual, then configure the transmitter for upscale burnout. To verify upscale burnout, simulate RTD burnout by disconnecting the RTD wires from the transmitter, then observe the transmitter output signal as indicated by the DMM. Record your observations
12. Configure the transmitter for downscale burnout. To verify downscale burnout, simulate RTD burnout by
