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 tester to ensure that the electrical interface is connected correctly.
2. Connect Power Supply (DC24V).
3. Set the alarm value, zero adjustment, calibrate and other parameters through remote control or interface.
4. Start the detector and monitor the gas concentration.
5. Connect to PLC, DCS and other systems or linkage control equipment as required.
Notice
• Operating voltage range is DC12V~ 30V to ensure stable power supply.
• Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (non-condensing).
• Use a three-core Shielding cable to connect a 4-20mA signal, and RS485 uses a four-core cable. When the transmission distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer needs to be grounded.
• The explosion-proof form is explosion-proof, and the installation and maintenance must comply with relevant explosion-proof standards.
• Sensor life is about 10 years, depending on the Operating Environment.
• Optional Accessories such as Power Adapter, conversion cable, etc., at the user's own expense.
