Electrical connection requirements

• Use of explosion – proof cables: Explosion – proof cables should be used for the electrical connection of the sensor to prevent the transmission of explosion – causing energy in the cable. The cable should be laid in a safe manner, avoiding damage and exposure, and should be protected by conduits or cable trays.
• Sealing of electrical connections: The electrical connection points of the sensor should be well – sealed to prevent the ingress of explosive substances. Sealing materials and methods that meet the explosion – proof requirements should be used to ensure the tightness of the connection.

 

Operation and maintenance requirements

• Regular inspection and maintenance: Regular inspections should be carried out to check the installation status, electrical connections, and working condition of the sensor to ensure its normal operation. If any problems or damages are found, they should be repaired or replaced in a timely manner. During maintenance, the relevant safety procedures should be strictly followed, and the power should be cut off and the surrounding explosive substances should be removed before the maintenance operation.
• Training of operators: The operators who use and maintain the sensor should receive professional training to understand the characteristics and safety requirements of the sensor in explosive environments, as well as the relevant emergency handling methods. Only trained and qualified personnel are allowed to operate and maintain the sensor.
• Compliance with safety regulations: During the operation of the sensor, all relevant safety regulations and operating procedures should be strictly followed, and any illegal operations and behaviors should be avoided.

3. How to ensure the proper installation of Honeywell LG1093AA24 in explosive environments?

To ensure the proper installation of Honeywell LG1093AA24 in explosive environments, the following steps should be taken:

• Understand the environment: Before installation, conduct a detailed assessment of the explosive environment, including the type, concentration, and distribution of explosive substances, as well as environmental factors such as temperature, humidity, and vibration. This helps determine the appropriate installation location and protection measures.
• Select suitable explosion – proof enclosures: Choose explosion – proof enclosures that meet relevant standards, such as ATEX or IECEx. The enclosure should have sufficient strength and tightness to prevent the ingress of explosive substances and the spread of internal sparks or heat to the outside.
• Proper grounding: Connect the sensor’s grounding terminal to a reliable ground source using a dedicated grounding wire. The grounding wire should have a large enough cross – sectional area to ensure low – resistance conduction. Regularly check the grounding resistance to ensure it is within the specified range.
• Install in a safe location: Avoid installing the sensor in areas where explosive gases, vapors, or dust are likely to accumulate. Keep it away from potential ignition sources such as open flames, heaters, and electrical equipment that may generate sparks. Ensure there is sufficient clearance around the sensor for proper ventilation and maintenance.
• Use explosion – proof cables and conduits: For electrical connections, use explosion – proof cables that are suitable for the environment. Route the cables through conduits or cable trays to protect them from mechanical damage and ensure they are properly sealed at both ends to prevent the ingress of explosive substances.
• Follow installation instructions: Strictly follow the installation instructions provided by Honeywell. This includes proper mounting of the sensor within the enclosure, connection of electrical wires, and setting of any relevant parameters or adjustments.
• Verify and test: After installation, perform a comprehensive verification and testing of the sensor. This includes checking the electrical connections, ensuring the sensor is functioning properly, and testing its response to simulated flame conditions. Also, check for any potential leaks or breaches in the explosion – proof enclosure.
• Training and documentation: Ensure that the personnel involved in the installation and maintenance of the sensor are properly trained on the installation procedures and safety requirements. Keep detailed installation records, including the location of the sensor, the type of enclosure used, and the testing results, for future reference and maintenance.
