Drager Pulsar 7000 Manual -

Clean the sapphire windows of both the Tx and Rx using a soft, lint-free cloth and a mild soap-and-water solution or specialized optical cleaner.

Remedy: Check input terminal voltage (must be > 18 V DC). Ensure the transmitter is cycling its pulsed light source (visible via diagnostic LEDs inside the transmitter enclosure housing).

The 4-to-20 mA current loop outputs specific fault levels to communicate device status to your safety PLC or control system. Current Output Diagnostic Matrix

Use the Dräger Pulsar Test Gas Card or specialized gas test cells to verify the detector's responsiveness without releasing actual gas into the atmosphere. Common Troubleshooting Scenarios

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

Wipe the sapphire optical windows of both the transmitter and receiver using a soft, lint-free cloth and a mild soap-and-water solution or specialized lens cleaner. Avoid abrasive pads or aggressive industrial solvents, which can scratch or degrade the anti-reflective lens coatings. Performance Verification (Bump Testing) Clean the sapphire windows of both the Tx

Initiate the command via the HART interface or PolySoft software.

Place the specialized calibration test film (which simulates a specific LEL-m gas concentration) directly into the slot on the receiver's weather shield.

The Dräger Pulsar 7000 Series consists of open-path explosion-proof gas detectors designed to continuously monitor flammable hydrocarbons. Operating over distances from 4 to 60 meters (Standard) or 30 to 120 meters (Long Range), these devices utilize infrared absorption technology to detect gases like methane, ethane, propane, and butane. The 4-to-20 mA current loop outputs specific fault
