Do not open the transmitter or receiver junction box enclosure when an explosive atmosphere is present unless the circuit is de-energised.
The Dräger Pulsar 7000 is a stationary, open path gas detector used to monitor for potentially explosive gases and vapors. Unlike traditional point detectors that sample the air at a specific location, open path detectors project an infrared beam across a monitoring path (e.g., a pipeline or perimeter). By measuring the absorption of specific wavelengths of light as the beam travels, the Pulsar 7000 can accurately calculate the concentration of hydrocarbon gases present, even from a distance.
Connect the 24V DC power supply to the designated positive (+) and negative (-) terminals.

If you need specific help with a particular aspect of your unit, tell me:
The Drager Pulsar 7000 features a range of advanced features that make it an ideal choice for gas detection applications. Some of the key features of the device include:
Dust, salt spray, and industrial grime will degrade signal quality. Clean the sapphire windows of both units regularly using a soft cloth and a mix of isopropyl alcohol and water. Avoid abrasive cleaners that could scratch the optical coatings.
Ensure the device certification matches the hazardous zone classification of your site (e.g., Zone 1 or Zone 2). Do not open the transmitter or receiver junction
The official Dräger Pulsar 7000 Safety Manual and related technical guides emphasize ease of use for technical personnel:
The Dräger Pulsar 7000 uses designated current loop levels to communicate active device status, warnings, and error faults to the central control room or gas panel. Analog Output Current States Current Output System Status Description / Action Required Normal Operation Zero gas detected in path. 4.0 to 20.0 mA Gas Measuring Range Linear scale corresponding to 0 to 4 (or 8) LEL*m. > 20.0 mA Over-range Gas concentration exceeds maximum scale limits. 3.5 mA Beam Block / Warning Optical path obscured (e.g., heavy fog, physical blockage). 2.0 mA Maintenance Mode Device is actively undergoing calibration or testing. ≤is less than or equal to 1.0 mA Fatal System Fault Internal hardware failure or critical misalignment. Maintenance and Trouble-Free Performance
Note: Ensure the internal jumpers are correctly set if configuring the 4-20 mA loop for "Source" (power provided by the Pulsar) or "Sink" (power provided by the control system). Commissioning and Optical Alignment
A: The manual describes two methods: cycle power for 10 seconds, or use the magnetic wand in the “reset” zone for 3 seconds. Note that some configurations require alarm acknowledgment from the host controller. By measuring the absorption of specific wavelengths of
Dräger Pulsar 7000 Series manual describes a high-performance, open-path infrared gas detector designed for stationary monitoring of explosive hydrocarbons. It is widely recognized for its robust build and rapid response times, making it a standard in oil, gas, and chemical industries. Key Technical Capabilities Rapid Detection
By treating the manual as an operational tool rather than a shelf decoration, you maximize the lifespan of your Pulsar 7000 and, more importantly, protect the lives of everyone relying on its readings.
