Move the brush vertically up and down carefully to scrub away oil films, rust, or biological scaling.
Replace and tighten the cleaning cap securely to prevent water leaks onto the electronics. Troubleshooting and Fault Codes
Use a specialized bottle brush to clean the sample cell tube manually to prevent buildup.
The OMD-11 unit must be fixed to a rigid vertical surface, ideally at eye level, using four M5 bolts. The unit should be mounted in a manner that protects it from extreme vibrations and excessive heat. 3.2. Piping and Sample Conditioning
To ensure consistent accuracy, operators should follow a routine maintenance schedule: OMD-11 Oil-in-Water Monitor Manual | PDF | Relay - Scribd deckma omd11 manual
The manual provides a clear, step-by-step standard operating procedure (SOP) for bringing the OMD-11 online.
24V AC/DC (Standard); 230V 50Hz versions available upon request Alarm Trip Points
Accessing, understanding, and correctly applying the is not just a maintenance task; it is a legal and safety imperative. This article breaks down everything you need to know about the manual, from where to find it to how to interpret its most complex sections.
Unscrew the cleaning cap located at the top of the measuring cell housing. Move the brush vertically up and down carefully
For more serious issues, the manual provides exploded-view diagrams and procedures for replacing major components:
While it describes the light-scattering principle briefly, advanced users sometimes want more detail on how temperature, pressure, or oil type affects readings.
| Component | Function | Common Manual Warning | | :--- | :--- | :--- | | Central Unit | Data processing & UI | Do not open while powered. | | Measuring Head | Optical detection | Clean lens annually. | | Blower Motor | Air aspiration | Check carbon brushes (if type M-4) every 10k hours. |
The is an oil-in-water monitor designed to meet International Maritime Organization (IMO) regulations for bilge alarm units (Resolution MEPC. 60(33)). It continuously monitors oily water discharge, primarily set to a 15 ppm limit. Manual & Technical Documentation The OMD-11 unit must be fixed to a
The OMD-11 manual outlines a device designed for reliability and ease of use in harsh marine environments. At the heart of the device is an that uses a combination of scattered and absorbed light to continuously analyze the sample stream, with a microprocessor processing the signals to produce a linearized output. Its key features, as listed in its marketing documents, highlight a practical focus:
Two independent alarm circuits, factory-set at 15 ppm but adjustable between 2–15 ppm. Output Signal: Reversible 0–20 mA or 4–20 mA.
This is where ignoring the manual leads to catastrophic false alarms or, worse, failure to detect an actual crankcase explosion.
Insert a soft bottle brush dipped in a mild liquid detergent or a specialized oil solvent.
