  5. Maintenance:

    • Regular maintenance is key to extending the life of the device and ensuring it operates efficiently.
    • This may include cleaning, replacing filters, and checking for wear and tear.

  6. Troubleshooting:

    • The manual should have a section on common issues, causes, and solutions.
    • Keep a log of maintenance and issues for future reference.

1. The Central Unit (Display and Control Panel)

This is the "brain." It houses the LCD display, keypad, power supply, and the microprocessor. The manual stresses that the central unit is usually located in the Engine Control Room (ECR).

Chapter 10: Safety Overrides – What the Manual Forbids

The Deckma OMD-11 manual has explicit "DANGER" warnings.

  1. Never bypass the alarm relay to the engine control system. (Engineers have been prosecuted for this after an explosion.)
  2. Never weld on the engine without disconnecting the measuring head. The arc flash will destroy the IR diode.
  3. Never use WD-40 or silicone sprays near the measuring head. The aerosol will coat the optics and cause a permanent "high mist" reading requiring factory cleaning.

Where to Find the Manual

This guide provides a general overview. For specific instructions, technical details, and safety precautions, refer to the official Deckma OMD11 manual.

The Deckma OMD-11 is a 15 ppm bilge alarm monitor designed to accurately measure oil content in water, primarily for maritime use with oily water separators. While it is an older model replaced by newer units like the OMD-24 or OMD-2008, it remains widely used and fully supported for calibration and repairs. Core Capabilities

Measurement Accuracy: It monitors oil content from 0 to 30 ppm, with a trend indication extending up to 50 ppm. IMO Compliance deckma omd11 manual

: The unit is designed to meet International Maritime Organization (IMO) resolution MEPC.60 (33) standards. Advanced Solids Suppression: A standout feature of the

is its ability to distinguish between actual oil particles and solids or water turbidity. This significantly reduces false alarms caused by non-oil contaminants like black iron oxide.

Dual Alarms: Features two independent alarm circuits, factory-set at 15 ppm but adjustable between 2 and 15 ppm. Technical Specifications Power Supply 24V AC/DC (standard) Output Signal 0(4) - 20 mA for external recorders or meters Protection Class IP 65 (watertight alloy enclosure) Sample Temp +1°C to +60°C Dimensions 175 x 190 x 220 mm; Weight: 3.5 kg Installation & Maintenance Highlights

Proximity: The manual mandates installing the monitor as close as possible to the oily water separator. The distance must not exceed 8 metres to ensure a response time under 20 seconds, as required by IMO regulations.

Calibration: The "Zero" point can be re-adjusted on-site using clean water via front panel buttons. However, full calibration must be performed by the manufacturer or an authorized provider like Mackay Marine during IOPP certificate renewals.

Serviceability: The unit uses plug-in technology for its optical components and circuit boards, making component replacement relatively straightforward.

to meet international maritime standards for 15 ppm bilge alarms, specifically IMO Resolution MEPC.60 (33)

. Although now considered an older model and no longer in production, it remains widely supported for calibration and spare parts. Technical Specifications General Overview

utilizes light-scattering technology to distinguish between oil particles, solids, and water turbidity : 0–30 ppm (with trend indication up to 50 ppm). : Meets IMO MEPC.60 (33) standards.

: Two independent circuits, factory-set at 15 ppm (adjustable from 2–15 ppm). Power Supply

: 24V AC/DC standard; other voltages available upon request. : IP 65 protection rating. : Approximately 3.5 kg. Installation Guidelines According to the OMD-11 manual , proper mounting is critical for regulatory compliance: : The monitor must be located within

of the oily water separator. Distances beyond this may exceed the 20-second response time mandated by IMO regulations.

: Use 10 mm OD copper or stainless steel pipe. Sampling points should be on vertical pipe sections to minimize air entrainment.

: Fix the unit to a rigid vertical surface using 4 x M5 screws, preferably at eye level. Maintenance and Calibration

B. Optical Offset Adjustment (The Service Menu)

This requires the official service code – usually not disclosed to ships’ crew to prevent tampering. However, the manual details the principle:

  1. A microcontroller compensates for lens soiling by increasing the LED current.
  2. When the required current exceeds 80% of max, the manual signals: Service required – Clean optics.

Fault 3: Intermittent Pre-Alarms – No visible mist.

Overall: ★★★★☆
The Deckma OMD-11 manual is reliable and practical for routine use, especially for maintenance and troubleshooting. It falls short in deep theory and spare parts details, but for most engineers and ship staff, it gets the job done well. Keep a copy in the engine control room and a PDF on a tablet for quick reference. Introduction : The Deckma OMD11 is designed for
