Optics require cleaning; system is still operating but accuracy may degrade. Normal Operation Clean air baseline; 0 LEL.m detected. Gas Detection
Initial rough alignment is done by eye, followed by fine adjustment using spring-loaded screws and a handheld terminal. No additional telescopes or mirrors are typically required. Electrical Wiring What (Short, Medium, Long) you are
The system requires an intrinsically safe connection to the Dräger Pulsar Interface Adapter (PIA) . The PIA is a robust, hazardous-area certified accessory that enables communication for calibration. 3. Calibration and Maintenance (According to the Manual)
| Problem / Fault | Possible Causes (as per manual) | Required Action (as per manual) | | :--- | :--- | :--- | | | Incorrect power supply | Establish correct power supply | | "Beam Block" or "Error" indication | Measuring path blocked between Tx and Rx Lenses of the Tx or Rx are dirty Tx and Rx not correctly aligned Tx and Rx set to different channels | Clear the measuring path Clean the lenses Align the Tx and Rx Set the same channel on both units | | No 4-20 mA signal | 4-20 mA cable connected incorrectly Pulsar Interface Adapter batteries empty | Check the 4-20 mA cable Replace batteries in the adapter | | Zero calibration unsuccessful | Gas present in the measuring path during compensation Lenses are dirty Tx and Rx incorrectly aligned | Ensure no gas is in the path during calibration Clean the lenses Align the Tx and Rx | | No communication via connection port | Communication connection is faulty Connector not fully inserted | Send device to Dräger Service Establish correct connection |
Connect the to a power supply (Typically 18–30 V DC).
