Standards
GB/T3836.1-2021、GB/T3836.31-2021、GB3836.15-2000、GB12476.1-2013、GB12358-2006、GBZ2.1-2007、GB4208-2008
Steps
1. Install the detector to ensure that the electrical interface is connected correctly.
2. Connect the power supply, Operating voltage is DC24V (12V~ 30V);
3. Set the alarm value, zero adjustment, calibrate, reset, modify the address code and other functions through the remote control free opening lid;
4. Start the detector and monitor the gas concentration;
5. Connect Output signals to receiving devices such as computers, PLCs, DCS, etc.
Notice
• Ambient Temperature should be kept in the range of -20~ 50 ℃;
• Environmental humidity should be maintained at 10-95% RH without condensation;
• Use a three-core Shielding cable to connect a 4-20mA signal. When the transmission distance exceeds 1000 meters, a single wire diameter needs to be ≥ 1.5mm, and the Shielding layer needs to be connected to the earth;
• Sensor life is 2 to 3 years, depending on the Operating Environment;
• The explosion-proof form is that the Probe transmitter and Sensor are both explosion-proof, and it is necessary to ensure that the installation meets the explosion-proof requirements;
• Optional Accessories such as Power Adapter, computer monitoring accessories, etc., need to be selected according to actual needs.
