| Fault Indication | Likely Cause | Manual Page Reference (Typical Rev 5.0) | | :--- | :--- | :--- | | | LED driver board failure or degraded LED. | Section 9.2.4 – Test points for voltage (5.2V DC expected). | | "Flow Failure" | Blocked sintered filter on the crankcase fitting or damaged diaphragm pump. | Section 8.3.1 – Filter replacement interval (every 8000 hrs). | | "Zero Offset" | Contaminated reference cell due to oil carryover. | Section 10.1 – Procedure for chemical cleaning of the measuring chamber. | | "Heater Current Low" | Open circuit in the heating element (crankcase cold but not warming). | Section 12 – Wiring diagram for heater (pins 14 & 15 on terminal strip X3). | | Frequent False Alarms | Condensation (not mist) – unit too cold. Manual specifies ambient range -25°C to +55°C. | Section 2.4 – Ensure a heated enclosure is used for cold climates. | deckma omd11 manual

By following the guidelines and recommendations outlined in this article and the Deckma OMD11 manual, you'll be well on your way to optimizing your oil-water separator's performance, ensuring a safe and efficient operation, and protecting the environment. : Unscrew the top brass cap of the measuring cell

The OMD-11 utilizes advanced optical technology to deliver real-time contamination data.

A primary engineering benefit of the OMD-11 is its advanced . Older bilge monitors often misidentified solid contaminants—such as rust particles, mud, or iron oxide—as oil, leading to false alarms. The OMD-11 significantly mitigates this background sensitivity. For example, a concentration of 15 mg/L of black iron oxide registers as a severe 15 ppm oil violation on older systems, but displays as a negligible 2 ppm on the OMD-11. Alarm Integration and Failsafe Logic | Section 9

This is the most referenced part of the manual. The OMD-11 requires a 3-point calibration:

is a critical piece of maritime and industrial equipment designed to monitor oil-in-water concentration. Specifically engineered for use with oily water separators, this monitor ensures that overboard discharge remains within international regulatory limits—typically 15 ppm (parts per million).
