The Deckma OMD-11 manual is not merely an instruction booklet; it is a class-approved safety document. During a PSC (Port State Control) inspection, the inspector will check that the manual is present, that the logbook entries match the manual’s test procedures, and that the crew knows how to navigate the menu without the book.
If you have lost your physical copy, do not wait. Download the Deckma OMD-11 manual PDF today, print the calibration section (Chapter 5), and laminate it for the engine control room. In the fight against crankcase explosions, your memory is fleeting, but the manual is permanent.
Final Tip from the Field: The most common user error is pressing "ENTER" too fast and accidentally changing the alarm threshold. When in doubt, turn the central unit off and on again – the EEPROM retains factory settings.

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).
Whether you are an engineer looking for a Deckma OMD-11 manual or a technician performing routine maintenance, this guide covers the essential operation, installation, and troubleshooting procedures for the OMD-11 series. 1. Key Specifications and Design
(Oil Monitoring Device) is known for its compact design and reliable measuring principles.
Measurement Range: 0 – 30 ppm (with an indicator up to 50 ppm). Accuracy: Meets IMO Resolution MEPC.60(33) standards.
Operating Voltage: Available in 115V or 230V AC, and 24V AC/DC variants. Here’s a helpful, practical review of the Deckma
Output Signals: Features a 0/4 - 20 mA signal for remote monitoring and two adjustable alarm relays. 2. Operating Principle: Light Scattering
uses the light scattering technique to detect oil particles. A light source passes through the sample water; if oil is present, the light scatters. Highly sensitive sensors measure this scattered light and convert it into a digital ppm reading on the front panel. 3. Installation Guidelines
To ensure accurate readings and prevent "false alarms," follow these manual-recommended installation steps:
Vertical Mounting: The unit should be mounted vertically to ensure bubbles do not get trapped in the measuring cell.
Sampling Point: Install the sampling probe on a vertical section of the discharge pipe, as far as possible from pumps or valves to avoid turbulence.
Sample Pressure: Ensure the sample water pressure is within the manual’s specified limits (typically 0.1 to 10 bar) to maintain a steady flow. 4. Calibration and Maintenance Regular maintenance is vital for MARPOL compliance.
Manual Cleaning: The measuring cell should be cleaned regularly using a dedicated bottle brush and mild detergent. A dirty glass tube is the most common cause of high ppm readings.
Zero Adjustment: Periodically flush the unit with clean, oil-free water to verify the "Zero" reading.
Calibration Check: According to most maritime regulations, the unit should be calibrated or checked by an authorized service provider every five years. 5. Troubleshooting Common Error Codes Go to product viewer dialog for this item. displays an error or fails to respond, check the following:
"Flow" Alarm: Indicates insufficient water flow through the measuring cell. Check for blocked sample lines or closed valves.
Constant 15+ PPM: Usually caused by a fouled measuring cell or air bubbles in the sample. Clean the cell and check the "Desiccator" (the small drying agent container) to ensure no moisture is affecting the optics.
System Failure: Check the internal fuse and ensure the power supply matches the unit's rating. 6. Importance of the Manual for Port State Control
Keeping a physical or digital copy of the Deckma OMD-11 manual on board is a requirement for many Port State Control (PSC) inspections. Inspectors often ask the Chief Engineer to demonstrate the alarm functionality and verify the unit's last calibration date against the manual's log.

Title: Looking for Deckma OMD-11 Manual – Bilge Alarm Calibration Help
Body:
Hey everyone,
I’m currently working with a Deckma OMD-11 oil content monitor (bilge alarm) and need the original manual (preferably the installation/calibration/maintenance section). We’re having intermittent issues with the 15 ppm alarm threshold drifting during warm-up.
I’ve found a few basic operation sheets online, but nothing with the full service parameters, zeroing procedure, or part numbers for the cleaning kit.
Does anyone have a PDF copy of the official Deckma Hamburg OMD-11 manual they could share? Alternatively, if you know the specific steps for a manual zero calibration after cleaning the measuring cell, that would be a lifesaver.
Cheers in advance.
