Deckma Omd11 Manual Updated Guide

While the OMD-11 is no longer in production, it remains fully supported.

The OMD-11 comes factory-calibrated, but occasional verification is mandatory.

Wire the main power supply and the alarm relays according to the specific terminal diagram found inside the housing cover. Always separate low-voltage signal lines (4-20mA) from high-voltage power lines to prevent electrical interference. 5. Daily Operation and Calibration Checks

The most common maintenance task. The glass sample tube must be cleaned using a bottle brush and mild detergent to prevent "false high" readings caused by scaling or debris. deckma omd11 manual

(For reference: unit is installed on a 2017-built bulk carrier, software version 2.1. We’re MEPC 107(49) compliant, but just doing regular maintenance.)

If the main logic board requires replacement:

: Provides a 0(4) - 20 mA output (representing 0 - 30 ppm) for external recorders or meters. While the OMD-11 is no longer in production,

The outlet piping must fall freely to an open funnel or non-pressurized drain line. Backpressure on the outlet will cause erratic readings or cell leakage.

Always isolate power sources before opening the instrument housing.

Ideally, the display panel should be at eye level with sufficient clearance on all sides for maintenance. Operation & Maintenance The glass sample tube must be cleaned using

A dedicated LED indicates a system fault, which can occur if the power supply fails or if there is a malfunction in the measuring cell. 5. Maintenance and Calibration

For more serious issues, the manual provides exploded-view diagrams and procedures for replacing major components:

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

If you have lost your physical copy, do not wait. Download the 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.

If the display reads higher despite using purely clean water, the optical tube is likely fouled and requires cleaning. 6. Maintenance and Cleaning Procedures
