Deckma OMD-11 is a legacy bilge alarm unit designed to monitor oil-in-water concentrations in marine environments, specifically to ensure compliance with IMO Resolution MEPC.60(33) standards. Core Function & Features
Restart power; replace main electronic board if it persists. Heavy fouling inside the glass tube. Clean the measuring cell thoroughly with a brush. No display illumination Blown fuse or zero input power. Check external circuit breakers and internal glass fuses. Flashing Alarm LED Oil content exceeds the set limit. Check OWS operation; stop overboard discharge manually. The OMD-11 is equipped with to provide a margin of safety
The unit should be mounted vertically to ensure bubbles do not get trapped in the measuring cell.
The OMD-11 is known for its compact design and improved "solids suppression," which prevents non-oil particles (like iron oxide) from triggering false alarms.
