Steps
1. Carry out function menu operations such as alarm value, zero adjustment, calibrate, reset, and address code modification of the detector through remote control without opening the lid;
2. Connection cable: 4~ 20mA choose three-core Shielding cable, RS485 choose four-core, when the distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer is connected to the earth;
3. Wireless transmission: built-in LORA, Zigbee module for short-range wireless transmission, or external GPRS/4G module for remote data transmission to the cloud platform;
4. Alarm settings: standard configuration of two-level alarm, can set conventional high and low alarm or interval control alarm;
5. Output signal connection: Select 4-20mA, RS485, voltage signal, switch signal or wireless signal output according to requirements.
Notice
• Operating voltage is DC24V (12V~ 30V) to ensure that the Power Adapter is connected correctly;
• Working Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (no condensation), avoid using beyond the range;
• Sensors have a lifespan of 2 to 3 years (depending on the environment used) and need to be checked and replaced regularly;
• When connecting the cable, the distance exceeding 1000 meters requires a single wire diameter ≥ 1.5mm, and the Shielding layer must be connected to the earth;
• The explosion-proof form is Probe Transmitter and Sensor are flameproof to ensure safe use in dangerous environments;
• Alarm mode includes on-site sound and light alarm, external alarm, etc., which needs to be set up and tested correctly;
• Optional Accessories such as 220V to 24V Power Adapter need to be paid by the user;
• Measurement certificate is optional, the user pays the fee;
• Wireless transmission module is optional and needs to be customized according to actual needs.
