5. Орнотуу жана орнотуу
The AI-DP1-LCD is designed for modular wall fitment in cleanroom environments.
5.1 Монтаждоо
The instrument enclosure has dimensions of 100mm (W) × 90mm (H) × 30mm (D), allowing for flush mounting into cleanroom modular walls. Ensure adequate space for rear connections.
5.2 Басым байланыштары
Connect the pressure tubing to the two 4mm stainless steel hose nipples located at the back of the unit. Ensure connections are secure to prevent leaks. The device is designed for use with air or non-corrosive gases.
5.3 Кубат туташтыруу
Connect the provided power adaptor to the device's power input. The typical power requirement is 24V DC.
5.4 Communication (Optional)
For integration with Building Management Systems (BMS), SCADA, or PLC, utilize the isolated RS485 communication port with Modbus protocols. Refer to the Modbus communication protocol documentation for detailed setup instructions (not included in this manual).
6. Иштөө нускамалары
6.1 Кубат күйгүзүлдү
Once powered on, the Graphic Backlit LCD will display the current differential pressure reading. The display also shows the date and time.
6.2 Reading Display
The LCD shows the differential pressure value in Pascals. This model has a factory-fixed unit selection for Pascals.
6.3 Ойготкуч функциясы
The device features a built-in high and low buzzer alarm. If the measured differential pressure exceeds or falls below the pre-set parameters, the buzzer will activate to indicate a process violation.
6.4 Alarm Acknowledgment
To acknowledge and silence an active alarm, press the 'ACK' button located on the front panel below the display. Acknowledging the alarm does not resolve the underlying issue; it only silences the buzzer.
7. Техникалык тейлөө
7.1 Тазалоо
Wipe the front stainless steel plate and LCD screen with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or display. Ensure no liquid enters the device.
7.2 Калибрлөө
The device comes with a Factory Calibration Certificate with NABL Standards. Regular re-calibration may be required depending on application and regulatory requirements. Contact INSTRUKART for calibration services.
