Drager Pulsar 7000 Manual [verified] Jun 2026

Proper optical alignment is a critical requirement for the Pulsar 7000 to ensure the infrared beam maintains a consistent signal-to-noise ratio. This process typically involves specialized alignment telescopes and precise adjustments of the mounting hardware. Because the system is often used in hazardous, explosion-prone areas, all mechanical adjustments must be performed according to the specific torque and locking specifications outlined in the official Dräger technical manual to maintain the integrity of the explosion-proof housing. 3. Commissioning and Operational Principles

It continuously monitors signal strength. If optics become dirty, a configurable "maintenance" signal (typically 3.5 mA) is issued, though the unit remains capable of gas detection. Safety Precautions from the Manual Dräger Pulsar 7000 Series (OTR 00**)

Wire the current loop to your Central Control System (DCS) or PLC. The manual dictates whether to wire the unit in a "Source" or "Sink" configuration via internal jumpers or specific terminal pins.

The Dräger Pulsar 7000 consists of two main components: a transmitter that emits an infrared beam and a receiver that detects the beam. If a hydrocarbon gas cloud crosses the path, the infrared light is absorbed, and the system triggers an alarm based on the gas concentration, measured in Lower Explosive Limit meters (LEL-m).

Using the specific, correct manual for the Dräger Pulsar 7000 is not just recommended—it is a safety requirement. The technical manual states, "Any use of the device requires full understanding and strict observation of this Technical Manual". Furthermore, the Safety Manual is a mandatory reference when the device is part of a certified safety loop, as it defines all assumptions, restrictions, and proof-test requirements for maintaining SIL 2 compliance.

For detailed technical specifications, wiring diagrams, and troubleshooting, consult the official Dräger Pulsar 7000 technical documentation.
