3.1 Монтаждоо:

• The device features a Stainless Steel Front Flush Plate for seamless integration into modular walls.
• Ensure adequate depth (Instrument Enclosure is 100×90×30 mm W×H×D) is available for proper fitment.
• Secure the unit firmly using appropriate fasteners for the wall material.

3.2 Электр байланыштары:

• Connect the device to a stable 24V DC power supply.
• For RS485 Modbus communication, connect the appropriate wiring to the isolated RS485 ports at the back of the unit. Refer to your BMS/SCADA/PLC system documentation for specific wiring diagrams.

3.3 Pressure Connections:

• Two 4mm stainless steel hose nipples are located at the back of the unit for pressure input.
• Connect appropriate tubing from the pressure source to these nipples. Ensure connections are secure and leak-free.
• Verify that the medium being measured is air or a non-corrosive gas.

4. Иштөө нускамалары

Once installed and powered, the AI-DP1-LCD will display differential pressure readings on its LCD screen.

4.1 Күйгүзүү:

Upon applying 24V DC power, the device will initiate and display the current differential pressure. The backlit LCD ensures visibility in various lighting conditions.

4.2 Reading Display:

The 128 x 64 LCD will show the differential pressure value. The unit of measurement (mm.W.C or Pascals) is factory-fixed. The display also shows the date and time.

4.3 Alarm Functionality:

• The device features a built-in buzzer alarm for high and low process set parameter violations.
• If the measured differential pressure falls outside the configured high or low limits, the buzzer will activate.
• басыңыз ACK button (located below the display) to acknowledge and silence the alarm.

4.4 Offset Provision:

The device includes an offset provision to meet audit requirements. Consult the detailed technical documentation or contact INSTRUKART support for instructions on configuring and utilizing this feature.

5. Техникалык тейлөө

Regular maintenance ensures the accuracy and longevity of your AI-DP1-LCD unit.

• Тазалоо: Gently clean the display and exterior with a soft, damp кездеме. Абразивдүү тазалагычтарды же эриткичтерди колдонбоңуз.
• Калибрлөө: The device comes with a factory calibration certificate. Periodic re-calibration by certified professionals is recommended to maintain accuracy, especially in critical applications.
• Туташуу текшерүү: Periodically inspect all electrical and pressure connections for tightness and integrity.
• Экологиялык шарттар: Зыяндын алдын алуу үчүн иштөө чөйрөсү белгиленген температуранын жана нымдуулуктун чегинде болушун камсыз кылыңыз.

6. Кыйынчылыктарды

This section provides basic troubleshooting steps for common issues. For more complex problems, contact INSTRUKART technical support.

6.1 No Display/Power:

• Verify that the 24V DC power supply is correctly connected and functioning.
• Check all power cables for damage or loose connections.

6.2 Inaccurate Readings:

• Ensure pressure connections are secure and free of leaks.
• Verify that the tubing is not kinked or obstructed.
• Confirm that the measured medium is air or a non-corrosive gas.
• Consider if re-calibration is due.

6.3 Alarm Constantly Active:

• Check if the differential pressure is genuinely outside the set high/low limits.
• Press the ACK button to acknowledge the alarm. If it immediately reactivates, the condition persists.
• Review the alarm set points to ensure they are appropriate for the application.
