Check the heater status settings via software. Inspect the housing O-rings for cracking. If water has penetrated the electronics enclosure, the unit must be sent to an authorized Dräger service center. Fault: Supply Voltage Error
:
Upon successful completion, the analog loop will output exactly 4.0 mA. 5. Maintenance, Functional Testing, and Troubleshooting
Use the integrated optical alignment sights on top of the transmitter and receiver housings. Manually adjust the pan-and-tilt brackets until the opposing unit is centered in the sight crosshairs. Lightly tighten the mounting bolts to hold this position. Step 2: Electronic Optimization via Handheld Terminal drager pulsar 7000 manual
The receiver will sample the baseline light levels for roughly 30 to 60 seconds.
: Summarizes electrical data, environmental tolerances, and hazardous area approvals (ATEX/IECEx). Technical Specifications Dräger Pulsar 7000 Series Safety Manual
: Unlike many systems, the Pulsar 7000 does not require a test gas or manual adjustment for calibration. A single person can align and commission the unit using a handheld terminal or PC software like PolySoft . Check the heater status settings via software
The manual contains strict warnings regarding the chemical nature of the device:
Cause: Physical object blocking the line of sight, severe dirt accumulation on lenses, or severe structural shifting causing misalignment.
The Pulsar 7000 is certified for use in Zone 1 and Zone 2 (or Class I, Div 1 and Div 2) hazardous areas. Ensure that the specific explosion-proof markings on your device label match the area classification of your facility. Beam Path Considerations Fault: Supply Voltage Error : Upon successful completion,
Confirm that the path is clear. The system will average the baseline readings over a short period.
Under favorable conditions (where lenses stay clean and the zero point remains stable), the maintenance interval can be extended to a maximum of 24 months . However, Dräger recommends a logbook to track all maintenance activities, including dates and personnel.
The commissioning phase ensures that the detector establishes an accurate baseline for the specific environmental conditions of the installation site. Baseline Validation
The Dräger Pulsar 7000 Safety Manual details the requirements for integrating the system into Safety Instrumented Systems (SIS) compliant with .
