Proper equipotential bonding is required. Connect the external earth terminal on both housings to your facility's structural ground. 3. Step-by-Step Installation Guide
The weather must be clear (no heavy fog, torrential rain, or blizzards). The optical windows must be completely clean and dry. Clean the sapphire lenses with a soft cloth
4 meters to 120 meters (depending on the model variant).
The optical path must be entirely free of hydrocarbon gases. Step-by-Step Zeroing Sequence:
ATEX, IECEx, FM, and CSA global certifications.
Methane, ethane, propane, butane, ethylene, and propylene. Verify that the control room display shows the
Cause: Low supply voltage, internal electronic component failure, or complete lack of communication from the transmitter unit.
By strictly adhering to the , you preserve the integrity of your facility's life-safety infrastructure. Ensure that all installation technicians are trained in optical alignment, perform semi-annual bump tests with certified Dräger test films, and address window obscuration faults immediately to maintain continuous, reliable gas monitoring protection.
