3. ຕັ້ງຄ່າ
3.1 ການຫຸ້ມຫໍ່
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 ການຕິດຕັ້ງ
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 ການເຊື່ອມຕໍ່ສາຍໄຟ
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.
- ການສະຫນອງພະລັງງານ: ເຊື່ອມຕໍ່ແຮງດັນ AC ທີ່ເໝາະສົມtage (e.g., 230V AC) to the designated power terminals.
- ເຊັນເຊີເຂົ້າ: Connect the temperature sensor (e.g., NTC, PT100) to the sensor input terminals. Observe polarity if applicable.
- ຄວບຄຸມຜົນຜະລິດ: 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 ການເປີດພະລັງງານເບື້ອງຕົ້ນ
After all connections are verified, apply power to the controller. The display should illuminate, showing the current temperature and default settings.
4. ການເຮັດວຽກ
4.1 ການສະແດງຜົນເກີນview
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 ການທໍາງານຂອງປຸ່ມ
- ປຸ່ມ SET: Used to enter parameter setting mode and confirm selections.
- ປຸ່ມຂຶ້ນ/ລົງ: Used to navigate through parameters and adjust values.
- ປຸ່ມ MODE: Used to switch between display modes or access advanced settings.
4.3 Setting Temperature Setpoint (SV)
- ກົດ SET button once. The SV value will flash.
- ໃຊ້ UP or ລົງ buttons to adjust the setpoint to the desired temperature.
- ກົດ SET button again to confirm the new setpoint. The display will return to showing the PV.
4.4 ການຕັ້ງຄ່າພາລາມິເຕີ
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 ຂຶ້ນ/ລົງ 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. ບໍາລຸງຮັກສາ
5.1 ການທໍາຄວາມສະອາດ
Clean the front panel of the controller periodically with a soft, damp ຜ້າ. ຢ່າໃຊ້ເຄື່ອງເຮັດຄວາມສະອາດຂັດຫຼືສານລະລາຍ, ເພາະວ່າສິ່ງເຫຼົ່ານີ້ສາມາດທໍາລາຍຈໍສະແດງຜົນຫຼື casing. Ensure no liquid enters the device.
5.2 ການກວດສອບປົກກະຕິ
