Steps
1. Install the detector to ensure that the electrical interfaces and cables are connected correctly.
2. Operating voltage DC24V (12V~ 30V);
3. Set the alarm value, zero adjustment, calibrate, reset, modify the address code and other parameters through remote control or interface;
4. Select Output signal type (such as 4-20mA, RS485, switch, etc.) and connect to the receiving device;
5. Start detection, monitor and display data and alarm status.
6. Regularly maintain and calibrate Sensors.
Notice
• Ambient Temperature should be kept in the range of -20~ 50 ℃;
• Environmental humidity of 10-95% RH to avoid condensation;
• Sensors have a lifespan of 2 to 3 years and need to be replaced regularly according to the Operating Environment;
• When connecting the cable, choose three-core Shielding cable for 4~ 20mA, four-core for RS485, and when the distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer is connected to the earth;
• The explosion-proof form is explosion-proof, and the installation must meet the relevant explosion-proof standards;
• Alarm settings can be configured with two levels of alarms, including conventional high and low alarms and interval control alarms;
• Optional Accessories such as Power Adapters and Monitoring Accessories need to be used on demand;
• Wireless transmission module is optional to ensure signal stability.
