1. Inleiding
The Selec CH-403-2 is a precision temperature chiller controller designed for industrial and commercial applications requiring accurate temperature regulation. This manual provides essential information for the safe and efficient installation, operation, and maintenance of your device. Please read this manual thoroughly before installation and operation.
2. Veiligheidsinligting
Neem altyd die volgende veiligheidsmaatreëls in ag om beserings en skade aan die toestel te voorkom:
- Maak seker dat die kragtoevoer afgeskakel is voordat enige bedrading of onderhoud uitgevoer word.
- Installasie en onderhoud moet slegs deur gekwalifiseerde personeel uitgevoer word.
- Verifieer dat die kragtoevoer voltage matches the specifications of the controller.
- Do not expose the controller to excessive moisture, dust, or corrosive gases.
- Verseker behoorlike aarding om elektriese skok te voorkom.
3. Opstelling
3.1 Uitpak
Carefully remove the controller from its packaging. Inspect the device for any signs of damage during transit. Report any damage to your supplier immediately.
3.2 Montering
The CH-403-2 is designed for panel mounting. Cut an opening of 45mm x 45mm (1.77" x 1.77") in the panel. Insert the controller into the opening and secure it using the provided mounting clamps. Ensure a snug fit to prevent dust and moisture ingress.
3.3 Bedradingsverbindings
Refer to the wiring diagram located on the side of the controller or in the detailed technical specifications. Ensure all connections are secure and correct before applying power.
- Kragtoevoer: Connect the appropriate AC voltage (e.g., 230V AC) to the designated power terminals.
- Sensorinvoer: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- Beheer uitset: Connect the chiller or heating element to the relay output terminals. Ensure the load current does not exceed the relay's maximum rating.
- Alarm Output (Optional): If applicable, connect external alarm devices to the alarm output terminals.
3.4 Aanvanklike opstart
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. Bedryf
4.1 Vertoon oorview
The front panel features a digital display showing the process value (PV) and set point (SV), along with indicator LEDs for output status (e.g., ON/OFF, Alarm).
4.2 Knoppie Funksies
- SET -knoppie: Word gebruik om parameterinstellingsmodus te betree en keuses te bevestig.
- OP/AF-knoppies: Used to navigate through parameters and adjust values.
- MODUS-knoppie: Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- Druk die STEL button once. The SV value will flash.
- Gebruik die UP or AF buttons to adjust the setpoint to the desired temperature.
- Druk die STEL button again to confirm the new setpoint. The display will return to showing the PV.
4.4 Parameterkonfigurasie
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the STEL button for several seconds until the first parameter code appears. Use the OP/AF buttons to navigate through parameters and the STEL button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. Onderhoud
5.1 Skoonmaak
Clean the front panel of the controller periodically with a soft, damp lap. Moenie skuurmiddels of oplosmiddels gebruik nie, aangesien dit die skerm of c kan beskadig.asing. Maak seker dat geen vloeistof die toestel binnedring nie.
5.2 Gereelde tjeks
- Inspekteer bedradingverbindings vir losheid of korrosie.
- Verify the temperature sensor is clean and properly installed.
- Check for any unusual noises or smells from the controller or connected equipment.
5.3 Kalibrasie
If temperature readings appear inaccurate, the sensor or controller may require calibration. Refer to the advanced parameter settings for sensor offset adjustment. For precise calibration, consult a qualified technician.
