6. Operating Instructions
The Inkbird ITC-100VH features a user-friendly interface for setting and monitoring temperature. The upper display (PV) shows the current process temperature, while the lower display (SV) shows the set target temperature.
Basic Operation:
- Power On: Once wired correctly, apply power to the controller. The displays will light up.
- Setting Temperature (SV): Press the SET button to enter the setting mode. Use the arrow keys (▲ / ▼) to adjust the Set Value (SV). Press SET again to confirm and exit.
- Monitoring: In normal operating mode, the PV display shows the actual temperature, and the SV display shows your target temperature.
- Output Indication: The 'OUT' indicator will illuminate when the control output is active. The 'AL1' and 'AL2' indicators will light up when the respective alarms are triggered.
Advanced Settings (Parameter Configuration):
The controller has various parameters for fine-tuning its operation, including sensor type, control mode (PID/ON-OFF), alarm settings, and self-tuning. Accessing and modifying these parameters typically involves pressing and holding the SET button for several seconds to enter the parameter menu. Consult the full technical manual for a complete list of parameters and their functions.
- Sensor Type: Ensure the controller is configured for the correct sensor type (e.g., K, PT100) to ensure accurate readings.
- PID Auto-Tuning: The self-adjust function (AT/RUN button) can automatically calculate optimal PID parameters for your specific heating/cooling system, improving control accuracy and stability.
- Alarm Settings: Configure alarm thresholds and modes (e.g., high limit, low limit) for the relay alarm output.
7. Maintenance
Regular maintenance ensures the longevity and accurate operation of your Inkbird ITC-100VH PID Temperature Controller.
- Cleaning: Periodically clean the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Connection Checks: Regularly inspect all wiring connections for tightness and signs of corrosion or damage. Loose connections can lead to inaccurate readings or intermittent operation.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage.
- Sensor Inspection: Check the temperature sensor for physical damage or degradation, which can affect measurement accuracy.
8. Troubleshooting
If you encounter issues with your ITC-100VH controller, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Power off | No power supply; Incorrect wiring; Blown fuse | Check power connections; Verify wiring against diagram; Replace fuse if necessary. |
| Inaccurate temperature reading | Incorrect sensor type setting; Faulty sensor; Loose sensor connection; Temperature offset needed | Verify sensor type in settings; Check sensor for damage; Secure sensor wiring; Adjust temperature offset if a consistent deviation is observed. |
| Controller not heating/cooling | Output wiring incorrect; Faulty SSR/relay; Set value not reached; PID parameters incorrect | Check output wiring; Test SSR/relay functionality; Adjust SV; Perform PID auto-tuning. |
| Alarm not triggering | Alarm settings incorrect; Alarm wiring incorrect; Faulty alarm device | Review alarm parameters; Check alarm output wiring; Test alarm device. |
