- Terminali 1-4: Output relays for Compressor, Defrosting, and Fan.
- Terminali 5-6: Power input (110V AC).
- Terminali 7-8: Room temperature probe connection.
- Terminal 9: Defrost probe connection.
- Copy Key Port: For parameter copying.
5. Setup u Operazzjoni
5.1 Tixgħel
After completing all wiring, apply power to the controller. The display will show the current temperature measured by the room temperature probe.
5.2 Issettjar tat-Temperatura
- Agħfas il- SET button once. The display will flash the current set temperature.
- Uża l- Up (▲) jew Down (▼) buttons to adjust the desired temperature.
- Agħfas il- SET button again to confirm and save the new setting.
5.3 Konfigurazzjoni tal-Parametru
Advanced parameters for cooling differential, defrost cycles, fan operation, and more can be accessed and adjusted through a dedicated menu. Refer to the detailed parameter list in the full technical manual for specific codes and ranges. Parameters can also be set and copied using a copy card for quick configuration across multiple units.
6. Modi Operattivi
6.1 Modalità tat-tkessiħ
When the measured temperature rises above the set temperature plus the cooling differential, the compressor relay activates to initiate cooling. It deactivates when the temperature drops to the set point.
6.2 Defrosting Mode
The controller supports various defrosting modes (e.g., timed defrost, manual defrost). During defrost, the defrost relay activates, and the compressor typically turns off. The defrost cycle duration and frequency are configurable parameters.
6.3 Fan Management
The fan output can be configured to operate continuously, only during cooling, or to turn off during defrost cycles, depending on the application requirements.
7. Manutenzjoni
Regular maintenance ensures the longevity and accurate operation of your temperature controller.
- Tindif: Imsaħ il-pannell ta 'quddiem b'artab, damp drapp. Tużax tindif jew solventi li joborxu.
- Spezzjoni: Periodically check wiring connections for tightness and signs of wear or corrosion.
- Iċċekkja tas-Sensor: Ensure temperature probes are clean and securely placed.
8 Issolvi l-problemi
This section addresses common issues you might encounter with the ETC-3000A controller.
| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| Display shows "HHH" or "LLL" | Temperature probe error (open circuit or short circuit) or out of range. | Check probe connection. Replace probe if damaged. Ensure temperature is within operating range. |
| Kontrollur mhux mixgħul | L-ebda provvista tal-enerġija jew wajers mhux korretti. | Verify power connection and voltage. Check wiring against diagram. |
