5. Opsætning og drift
5.1 Tænd
After completing all wiring, apply power to the controller. The display will show the current temperature measured by the room temperature probe.
5.2 Indstilling af temperatur
- Tryk på SÆT button once. The display will flash the current set temperature.
- Brug Up (▲) eller Ned (▼)-knapperne til at justere den ønskede temperatur.
- Tryk på SÆT button again to confirm and save the new setting.
5.3 Parameterkonfiguration
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. Driftstilstande
6.1 Køletilstand
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 Ventilatorstyring
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. Vedligeholdelse
Regular maintenance ensures the longevity and accurate operation of your temperature controller.
- Rensning: Tør frontpanelet af med en blød, damp klæde. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Inspektion: Kontroller regelmæssigt ledningsforbindelserne for tæthed og tegn på slid eller korrosion.
- Sensorkontrol: Ensure temperature probes are clean and securely placed.
8. Fejlfinding
This section addresses common issues you might encounter with the ETC-3000A controller.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| 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. |
| Controlleren tænder ikke | Ingen strømforsyning eller forkert ledningsføring. | Verify power connection and voltage. Check wiring against diagram. |
| Compressor/Fan not activating | Incorrect temperature settings, parameter errors, or faulty wiring to the load. | Review set temperature and differential. Check relevant parameters. Inspect wiring to compressor/fan. |
| Defrost not initiating | Defrost parameters incorrectly set or defrost probe issue. | Check defrost cycle parameters (duration, interval). Verify defrost probe connection. |
