2. Saugos informacija
Visada laikykitės šių saugos priemonių, kad išvengtumėte sužalojimų ir įrenginio pažeidimų:
- Prieš atlikdami bet kokius laidų prijungimo ar techninės priežiūros darbus, įsitikinkite, kad maitinimo šaltinis yra atjungtas.
- Montavimą ir techninę priežiūrą turėtų atlikti tik kvalifikuoti darbuotojai.
- Patikrinkite, ar maitinimo šaltinio ttage matches the specifications of the controller.
- Do not expose the controller to excessive moisture, dust, or corrosive gases.
- Užtikrinkite tinkamą įžeminimą, kad išvengtumėte elektros smūgio.
3. Sąranka
3.1 Išpakavimas
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 Montavimas
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 Laidų jungtys
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.
- Maitinimas: Connect the appropriate AC voltage (e.g., 230V AC) to the designated power terminals.
- Jutiklio įvestis: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- Valdymo išvestis: Connect the chiller or heating element to the relay output terminals. Ensure the load current does not exceed the relay's maximum rating.
- Signalizacijos išvestis (pasirinktinai): If applicable, connect external alarm devices to the alarm output terminals.
3.4 Pradinis įjungimas
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. Operacinis
4.1 Ekranas baigtasview
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 Mygtukų funkcijos
- SET mygtukas: Naudojamas parametrų nustatymo režimui įjungti ir pasirinkimams patvirtinti.
- AUKŠTYN/ŽEMYN mygtukai: Naudojamas parametrams naršyti ir reikšmėms koreguoti.
- MODE mygtukas: Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- Paspauskite NUSTATYTI button once. The SV value will flash.
- Naudokite UP or ŽEMYN buttons to adjust the setpoint to the desired temperature.
- Paspauskite NUSTATYTI button again to confirm the new setpoint. The display will return to showing the PV.
4.4 Parametrų konfigūracija
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the NUSTATYTI button for several seconds until the first parameter code appears. Use the AUKŠTYN/ŽEMYN buttons to navigate through parameters and the NUSTATYTI button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. Priežiūra
5.1 Valymas
Clean the front panel of the controller periodically with a soft, damp šluoste. Nenaudokite abrazyvinių valiklių ar tirpiklių, nes jie gali pažeisti ekraną arbaasing. Ensure no liquid enters the device.
5.2 Reguliarūs patikrinimai
- Patikrinkite laidų jungtis, ar nėra atsilaisvinimų ar korozijos.
- Verify the temperature sensor is clean and properly installed.
- Check for any unusual noises or smells from the controller or connected equipment.
5.3 Kalibravimas
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.
