Mounted directly on the engine crankcase door. The manual warns: Never install the measuring head where it is exposed to direct water spray or extreme vibration without dampeners. It contains:
Reversible 0–20 mA or 4–20 mA (Corresponds to 0–30 ppm) 0.1 to 8 bar Sample Flow Rate Approximately 0.5 to 4 liters per minute Ingress Protection Rating Physical Dimensions 175 mm (W) x 190 mm (H) x 220 mm (D) Total Weight Core Principles of Operation deckma omd11 manual
The Deckma OMD11 manual is a vital resource for anyone working with this oil-water separator. By understanding the equipment's design, operation, and maintenance requirements, you can ensure optimal performance, efficient maintenance, and compliance with environmental regulations.
: If the oil concentration exceeds the 15 ppm (parts per million) legal limit set by IMO regulations, the monitor triggers an alarm. It typically activates a relay to automatically close the overboard discharge valve, redirecting polluted water back to a holding tank. Key Installation & Maintenance Rules
The Deckma OMD11 is a high-performance oil separator system that utilizes advanced technology to separate oil and water. The system consists of a series of components, including a separator unit, a control unit, and a monitoring system. The separator unit uses a combination of gravity and coalescence to separate oil and water, while the control unit regulates the system's operation and monitors its performance. The monitoring system provides real-time data on the system's performance, allowing for adjustments to be made as needed. : Marine enthusiasts or professionals might share manuals
If the main logic board requires replacement:
A 3-way cock connects the OMD-11 to the separator’s clean water outlet for cleaning and calibration. Piping Material: Use OD copper or stainless steel pipe.
A significant section of the manual is dedicated to fault finding. The most common issues, as implied by the maintenance schedule, are related to contamination. If the display fails to zero during startup, the manual instructs the operator to first perform a mechanical cleaning of the glass tube before attempting a zero adjustment. Other potential faults (like a complete loss of display or alarm function) would necessitate checking the power supply to terminals 1 & 2 and inspecting the PCB for damage or loose connections.

The manual provides a clear, step-by-step standard operating procedure (SOP) for bringing the OMD-11 online.
The distance between the separator and the monitor should not exceed 8 meters to ensure compliance with max response times. 4. Operation and Display
