Training Your Crew Using the Deckma OMD11 Manual

A manual is only useful if the crew can apply it. Create a "One-Page Emergency Card" based on the manual’s Section 11: Emergency Bypass Procedure.

Drill Scenario: Crankcase oil mist alarm sounds during maneuver.

From the Manual:

Do not stop the engine immediately – dangerous propeller pitch situation.
Press Alarm Acknowledge (silences horn for 30 seconds).
Reduce engine load below 50%.
If alarm persists after 60 seconds, stop engine and open indicator cocks.
Bypass is only allowed if manual section 11.3 conditions are met (visual inspection of crankcase via drain plug – no smoke).

Post this drill summary in the ECR. The full manual remains the reference for investigation (why did it alarm?).

3. The Aspiration System (Blower Unit)

A central blower draws sample air from the engine through pipes to the measuring head. The Deckma OMD-11 manual contains a strict warning: The blower must create a negative pressure of approximately 200 mm water column. Any leak in the sampling tube results in false low readings.

Safety tips

Always start on a higher range if unsure.
Never measure current by placing the meter directly across a voltage source without using the proper jack and range.
Inspect test leads for damage before use.
Use the correct input jack (fused mA vs high-current 10A) to avoid blowing fuses.
Observe category ratings (CAT II/CAT III) printed on the meter; avoid using the meter in environments beyond its rating.

Conclusion: The Manual is a Legal Document

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.

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. deckma omd11 manual

The Deckma OMD-11 is a high-precision 15 ppm bilge alarm monitor designed to improve the reliability and operation of oily water separator (OWS) systems. Meeting the requirements of IMO Resolution MEPC.60(33), the OMD-11 utilizes advanced solids suppression technology to distinguish between oil particles, solid particles, and water turbidity. Key Technical Specifications

The OMD-11 is a compact, lightweight unit (3.5 kg) built for the harsh environments of a ship's engine room. Specification Measuring Range 0 – 30 ppm (Trend indication up to 50 ppm) Accuracy Better than ± 5 ppm (per IMO requirements) Alarm Set Points Factory set at 15 ppm; adjustable from 2 to 15 ppm Power Supply 24V AC/DC ± 15% Output Signal 0(4) – 20 mA, selectable Protection Class Sample Flow Approx. 0.5 – 4 L/min (pressure dependent) Installation Guidelines

Proper installation is critical to ensure the monitor's response time remains within the 20-second limit mandated by IMO regulations.

Location: Mount the OMD-11 as close to the oily water separator as possible, typically within 8 meters.

Mounting: Use a rigid vertical surface. Ensure enough clearance on all sides for maintenance.

Piping: Use R 1/4" female pipe connections. It is recommended to use copper or stainless steel pipes (10 mm OD) to avoid corrosion.

Sample Point: The tapping should be on a vertical section of the discharge line to prevent air bubbles from interfering with the optical sensor. Operation & Calibration

The OMD-11 features 14-segment LEDs and simple push-button controls for on-site adjustments. OMD-11 Oil-in-Water Monitor Manual | PDF | Relay - Scribd

is a light-scattering oil-in-water monitor designed to meet IMO MEPC.60(33) regulations for 15 ppm oily water separators. Key Technical Specifications

Measurement Range: 0–30 ppm (Trend indication up to 50 ppm). Accuracy: Better than ±5 ppm (within IMO requirements). Power Supply: 24V AC/DC ±15% (5 VA consumption).

Alarms: Two independent circuits factory-set at 15 ppm (adjustable between 2–15 ppm). Response Time: Adjustable between 2–20 seconds. Output Signal: 0(4) – 20 mA for external recording. Installation Guidelines

Location: Mount the unit on a rigid vertical surface using 4 x M5 screws. General Overview

Distance: It must be placed as close as possible to the oily water separator. The distance must never exceed 8 meters to ensure a response time under 20 seconds, as required by IMO regulations.

Positioning: Ideally, the display panel should be at eye level with sufficient clearance on all sides for maintenance. Operation & Maintenance

Principle: The unit uses several optical sensors to measure a combination of scattered and absorbed light to determine oil concentration.

Functional Testing: To check the unit, run oil-free water through the system to purge it and ensure the reading drops to zero.

Calibration: While the OMD-11 is an older model, it is still supported. Calibration must be performed by certified providers like Mackay Marine to meet IMO requirements.

Component Repair: Replacing electronic components (except fuses) typically requires re-calibration to avoid inaccurate readings. Troubleshooting Indicators

LED Indicators: The front panel includes "Alarm 1," "Alarm 2," and "Error/Fault" LEDs.

System Fault: In the event of a power failure or system malfunction, all internal relays automatically switch to the alarm condition.

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. Introduction : The Deckma OMD11 is designed for

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.

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.
