2. Maklumat Keselamatan
Sentiasa patuhi langkah keselamatan berikut untuk mengelakkan kecederaan dan kerosakan pada peranti:
- Pastikan bekalan kuasa diputuskan sebelum melakukan sebarang pendawaian atau penyelenggaraan.
- Pemasangan dan servis hanya boleh dilakukan oleh kakitangan yang berkelayakan.
- Sahkan bahawa bekalan kuasa voltage matches the specifications of the controller.
- Jangan dedahkan pengawal kepada kelembapan, habuk atau gas menghakis yang berlebihan.
- Pastikan pembumian yang betul untuk mengelakkan kejutan elektrik.
3. Persediaan
3.1 Membongkar
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 Pemasangan
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 Sambungan Pendawaian
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.
- Bekalan Kuasa: Connect the appropriate AC voltage (e.g., 230V AC) to the designated power terminals.
- Input Sensor: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- Output Kawalan: 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 Kuasa Permulaan
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. Beroperasi
4.1 Paparan Terlaluview
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 Fungsi Butang
- Butang SET: Digunakan untuk memasuki mod tetapan parameter dan mengesahkan pilihan.
- Butang ATAS/BAWAH: Used to navigate through parameters and adjust values.
- Butang MOD: Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- Tekan ke SET button once. The SV value will flash.
- Gunakan UP or TURUN buttons to adjust the setpoint to the desired temperature.
- Tekan ke SET button again to confirm the new setpoint. The display will return to showing the PV.
4.4 Konfigurasi Parameter
To access advanced parameters such as hysteresis, calibration offset, or delay times, press and hold the SET button for several seconds until the first parameter code appears. Use the ATAS/BAWAH buttons to navigate through parameters and the SET button to select and modify values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.
5. Penyelenggaraan
5.1 Pembersihan
Clean the front panel of the controller periodically with a soft, damp kain. Jangan gunakan pembersih atau pelarut yang kasar, kerana ini boleh merosakkan paparan atauasing. Ensure no liquid enters the device.
5.2 Pemeriksaan Berkala
- Inspect wiring connections for looseness or corrosion.
- Verify the temperature sensor is clean and properly installed.
- Check for any unusual noises or smells from the controller or connected equipment.
5.3 Penentukuran
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.
