Click "Auto Mode" button to set the channel to automatic mode and click "Manual Mode" button to set the channel to manual mode.
Figure 3.4.2 Channel Auto Tuning
| Field | Content |
|---|---|
| Set Value Setting | Set the target temperature value of PID control. |
| AT Bias Setting | The point set as the set value (SV) in the auto tuning can be rearranged by this value. The auto tuning is performed with having the AT point (the point rearranged by the setting) as its center. When the auto tuning is completed, AT bias is not added and a control is performed toward the set value (SV). |
| AT Loop Disconnection Detection Flag | This function detects loop disconnections during auto tuning (AT). With this function, a channel that is not controlled can be detected during auto tuning, thus the error channel is detected more than two hours before the auto tuning error occurs. The auto tuning continues even if an alert is output for the loop disconnection detection. |
| AT Loop Disconnection Detection Setting | Using this function detects an error occurring within a control system (control loop) due to reasons such as a load (heater) disconnection, an externally-operable device (such as a magnetic relay) failure, and input disconnection. |
| AT Mode Selection | Select the auto tuning mode from the following two modes according to the controlled object to be used. Standard mode: The standard mode is appropriate for most controlled objects. This mode is especially suitable for controlled objects that have an extremely slow response speed or can be affected by noise or disturbance. However, PID constants of slow response (low gain) may be calculated from controlled objects whose ON time or OFF time in the auto tuning is only around 10s. In this case, PID constants of fast response can be calculated by selecting the high response mode and performing the auto tuning. High response mode: This mode is suitable for controlled objects whose ON time or OFF time in the auto tuning is only around 10s. PID constants of fast response (high gain) can be calculated. However, the temperature process value (PV) may oscillates near the set value (SV) because of the too high gain of the PID constants calculated. In this case, select the normal mode and perform the auto tuning. |
| Backup of the Calculated Value | By enable the field at the start of auto tuning, the calculated value is automatically backed up into E2PROM on completion of auto tuning. |
| AT Status | Indicate the auto tuning status. |
Click "ON" button to request the channel to do PID auto tuning.
If the PID auto tuning is complete normally or any error occurred while doing tuning, please click "OFF" button to withdraw the request;
Note:
Figure 3.4.3 Channel PID Constants
| Field | Content |
|---|---|
| Ph | Set proportional band (P)/heating proportional band (Ph)/cooling proportional band (Pc) to perform PID control. Heating proportional band (Ph) setting: 0 to 10000 (0.0% to 1000.0%) . |
| Pc | Set proportional band (P)/heating proportional band (Ph)/cooling proportional band (Pc) to perform PID control. Cooling proportional band (Pc) setting: 1 to 10000 (0.1% to 1000.0%) . |
| I | Set integral time (I) to perform PID control. The setting range is 0 to 3600 (0 to 3600s). |
| D | Set derivative time (D) to perform PID control. The setting range is 0 to 3600 (0 to 3600s). |
| LP | Errors such as disconnection of resistors, malfunction of an external controller, and errors of the control system due to troubles such as disconnection of the sensor can be detected by the loop disconnection detection function. If temperature does not change by 2°C (℉) or more in the Loop disconnection detection judgment time, a loop disconnection is detected. The setting range is 0 to 7200 (s) . |
Click "Backup PID Constants" button to save the PID constants of all channels into E2PROM at once.
