The Dräger Pulsar 7000 is an infrared (IR) gas detection system consisting of two primary components: a which emits an infrared light beam, and a Receiver (Rx) which detects the light beam and analyzes it for target gas attenuation.
Check power supply terminal voltages; re-verify alignment via HART; check system event log via PolySoft. Fluctuating mA around 4.0 mA
A physical object (vehicle, crane, scaffolding) is blocking the line of sight, or the windows are heavily soiled.
Mount both units to rigid, vibration-free structures (such as heavy concrete pillars or reinforced steel beams) to prevent beam deviation during high winds. drager pulsar 7000 manual
ATEX, IECEx, and cCSAus certified for Zone 1/2 and Class I, Div 1 environments. Safety Integrity Level: SIL 2 certified by TÜV. Installation and Mechanical Mounting
Utilize the built-in rifle sight or the optional alignment telescope mounted on the device. Adjust the pan-and-tilt mechanism until the opposite unit is centered in the crosshairs. Tighten the mounting bolts loosely to hold the position. Step 2: Electronic Alignment using a Handheld Terminal
The manual details strict electrical guidelines to maintain the system's explosion-proof explosion rating. Wiring Configuration The Dräger Pulsar 7000 is an infrared (IR)
3.0 mA (or 3.4 mA depending on software configuration) 4. Commissioning and Alignment Procedure
Signal levels between 4 and 20 mA represent the detected gas concentration.
Upon successful completion, the analog loop will output exactly 4.0 mA. 5. Maintenance, Functional Testing, and Troubleshooting Mount both units to rigid, vibration-free structures (such
Maintenance needed (e.g., dirty optics, low signal). Red: Gas alarm.
The Pulsar 7000 uses high-intensity infrared light sources. Avoid staring directly into the transmitter lens at close proximity. 3. Installation Best Practices
When errors occur, the system will often indicate a fault condition via the status LEDs or the 4-20 mA output. The manual provides a detailed table for common issues.
Repeat the process on the receiver unit until the manual's recommended target signal percentage (typically ) is achieved. Fully torque all mounting hardware. Step 3: Zeroing the System
