3.1 ማሸግ
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 መጫን
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 የወልና ግንኙነቶች
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.
- የኃይል አቅርቦት; ተገቢውን የ AC vol ያገናኙtage (e.g., 230V AC) to the designated power terminals.
- ዳሳሽ ግቤት Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- የቁጥጥር ውጤት፡ Connect the chiller or heating element to the relay output terminals. Ensure the load current does not exceed the relay's maximum rating.
- የማንቂያ ውፅዓት (አማራጭ) If applicable, connect external alarm devices to the alarm output terminals.
3.4 የመጀመሪያ ኃይል-አፕ
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. አሠራር
4.1 ማሳያview
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 የአዝራር ተግባራት
- አዘጋጅ አዝራር ፦ የፓራሜትር ቅንብር ሁነታን ለማስገባት እና ምርጫዎችን ለማረጋገጥ ይጠቅማል።
- ወደላይ/ወደታች አዝራሮች፡- በመለኪያዎች ውስጥ ለማሰስ እና እሴቶችን ለማስተካከል ጥቅም ላይ ይውላል።
- MODE አዝራር፡- Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- የሚለውን ይጫኑ አዘጋጅ button once. The SV value will flash.
- የሚለውን ተጠቀም UP or ታች buttons to adjust the setpoint to the desired temperature.
- የሚለውን ይጫኑ አዘጋጅ button again to confirm the new setpoint. The display will return to showing the PV.
4.4 የመለኪያ ውቅር
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the አዘጋጅ button for several seconds until the first parameter code appears. Use the ወደላይ/ወደታች buttons to navigate through parameters and the አዘጋጅ button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. ጥገና
5.1 ጽዳት
Clean the front panel of the controller periodically with a soft, damp ጨርቅ። ሻካራ ማጽጃዎችን ወይም መሟሟቶችን አይጠቀሙ፣ ምክንያቱም እነዚህ ማሳያውን ወይም ጨረሩን ሊጎዱ ስለሚችሉasinሰ. ምንም ፈሳሽ ወደ መሳሪያው ውስጥ እንደማይገባ ያረጋግጡ.
5.2 መደበኛ ቼኮች
