3-1 Setup Procedure
Use the following procedure to perform gradient temperature control.
1. Select the models.
2. Set the Communications unit numbers.
3. Make the I/O settings.
4. Make the gradient group settings.
5. Arrange the Sensors.
6. Register the configuration.
7. Set decimal point position B.
8. Make the SP and alarm settings.
9. Perform tuning for gradient temperature control.
10. Start control.
11. Perform tuning for 2-PID control.
12. Check the heater burnout alarm status.
Example: Performing 3-channel Gradient Temperature Control
• Gradient temperature control is performed for 3 groups.
• Also, 2-PID control is performed for three channels in addition to gradient
temperature control.
• Heater burnout is detected for all channels.
1. Select the models.
TC2 Basic Units are used because heater burnout detection is performed.
• Select TC2 Units to detect heater burnout.
• Select TC4 Units when not detecting heater burnout.
Note A mixture of TC2 and TC4 Units can be used.
Here, a total of 12 channels are required, so 6 TC2 Units are needed.
