1. Installation: Select the piped or Wall-Mounted installation method according to the application. 2. Wiring: Connect the corresponding cable according to the signal output mode (such as 4~ 20mA or RS485). 3. Power supply: Connect 12~ 30VDC DC power supply, the standard power supply for a single device is 24V. 4. Boot: The device starts after power on, and the 1.7-inch high definition color screen displays real-time concentration. 5. Parameter settings: Use the standard infrared remote control, do not open the lid for one-button operation in dangerous situations, modify the alarm point, perform concentration calibrating, zero point calibrating, muffling, restore factory settings, etc. 6. Monitoring and alarm: The equipment starts to continuously monitor online. When the concentration exceeds the standard, the on-site sound and light alarm (optional) starts, the display screen visual alarm, and the relay switch output signal. 7. Data transmission: send data to the monitoring center, PLC or DCS system through wired (RS485, 4~ 20mA) or wireless remote transmission, network transmission.
• When the installation method is pipeline type, the Operating Pressure shall be atmospheric pressure +/- 30%, and the pressure reduction treatment shall be carried out beyond the range. • Connecting cable selection: choose three-core Shielding cable for 4~ 20mA output, and four-core cable for RS485 output. When the transmission distance exceeds 1000 meters, the single wire diameter should be ≥ 1.5mm, and the Shielding layer needs to be grounded. • Power configuration: The standard power supply of a single device is 24V, 1A or greater than 1A DC regulated switching power supply. A 24V, 2.1A switching power supply can drive 40 toxic Gas detectors, or 15 combustible and infrared Gas detectors. • Optional high temperature and high humidity pretreatment system can be used to detect high temperature flue gas. • Built-in Filter can be used in high humidity or high dust environment. • The equipment has a misoperation identification function, which can automatically identify and prevent misoperation of concentration calibrating. • The device has anti-reverse connection function, please pay attention to polarity when wiring. • Options include sound and light alarms, power supplies, monitoring accessories (host computer software, converters, etc.), wireless transmission modules, and various preprocessing systems and installation accessories, which users can choose according to their actual needs.
