1. Install the detector to ensure that it is firmly fixed. 2. Connect the power supply and Operating voltage DC24V. 3. Set the alarm value, zero, calibrate, reset and modify the address code through the remote control free-opening lid. 4. Select Output signal type (e.g. 4-20mA, RS485) and connect to receiving device. 5. Start the detector and observe the LCDTFT display to confirm the working status. 6. Perform signal fine-tuning or wireless transmission settings as required.
• Operating ambient temperature range is -20~ 50 ℃, Humidity is 10-95% RH (no condensation). • Sensor life is 2 to 3 years, depending on the Operating Environment. When connecting cables, choose three-core Shielding cables for 4 to 20mA, and four-core cables for RS485. When the distance exceeds 1000 meters, the diameter of a single wire is ≥ 1.5mm. Shielding layer needs to be connected to the earth. • Wireless transmission can choose built-in or external modules, and remote data transmission requires optional GPRS/4G modules. The alarm setting supports conventional high and low alarms and interval control alarms, and the standard configuration is two-level alarms. • Electrical interface default M20X1.5 internal thread, optional 3/4NPT, 1/2NPT. • Optional Accessories include 220V to 24V Power Adapter, computer monitoring accessories, etc. Measurement certificate fee is paid by the user.
