- 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 ഇലക്ട്രിക്കൽ കണക്ഷനുകൾ:
- 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. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once installed and powered, the AI-DP1-LCD will display differential pressure readings on its LCD screen.
4.1 പവർ ഓൺ:
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.
- അമർത്തുക എ.സി.കെ 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. പരിപാലനം
Regular maintenance ensures the accuracy and longevity of your AI-DP1-LCD unit.
- വൃത്തിയാക്കൽ: Gently clean the display and exterior with a soft, damp തുണി. ഉരച്ചിലുകളുള്ള ക്ലീനറുകളോ ലായകങ്ങളോ ഉപയോഗിക്കരുത്.
- കാലിബ്രേഷൻ: The device comes with a factory calibration certificate. Periodic re-calibration by certified professionals is recommended to maintain accuracy, especially in critical applications.
- കണക്ഷൻ പരിശോധന: Periodically inspect all electrical and pressure connections for tightness and integrity.
- പരിസ്ഥിതി വ്യവസ്ഥകൾ: കേടുപാടുകൾ തടയുന്നതിന് പ്രവർത്തന അന്തരീക്ഷം നിശ്ചിത താപനിലയിലും ഈർപ്പത്തിലും ഉണ്ടെന്ന് ഉറപ്പാക്കുക.
6. പ്രശ്നപരിഹാരം
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.
- എല്ലാ പവർ കേബിളുകൾക്കും കേടുപാടുകൾ സംഭവിച്ചിട്ടുണ്ടോ അല്ലെങ്കിൽ കണക്ഷനുകൾ അയഞ്ഞിട്ടുണ്ടോ എന്ന് പരിശോധിക്കുക.
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.
6.4 RS485 Communication Issues:
- Verify RS485 wiring connections and polarity.
- Check Modbus address and baud rate settings on both the indicator and the master device (BMS/SCADA/PLC).
- Ensure proper termination resistors are used if required by the network.
