Product questions
What is the DG 6U-3 pressure adjustment range?
Published descriptions differ: some specify 0.5–6 mbar, while another specifies 0.4–6 mbar. The switching point is adjusted by handwheel. Confirm the range on the actual unit or its current manufacturer documentation, especially if the setting is near the lower limit.
Can the DG 6U-3 monitor both gas and air pressure?
The DG 6U-3 monitors gas and air pressure. The DG..U design supports positive, negative and differential pressure monitoring, but the permissible medium depends on the pressure mode: the published product data lists gas and air for positive pressure and air or flue gas for negative pressure. Confirm the medium and pressure connections for the intended installation.
What electrical connection does the DG 6U-3 use?
The DG 6U-3 is specified with screw terminals. Check the equipment's electrical requirements and the unit marking before selecting it; other DG versions use different electrical connections.
Is the DG 6U-3 interchangeable with a DG 6T switch?
Do not assume a direct interchange. Published comparisons identify differences in pressure-port threads, indicator lamp and approvals between these versions. Provide the existing switch's full part number, equipment model and serial number, operating pressure and electrical details so suitability can be checked before replacement.
