Check the main switchboard circuit breaker. Isolate power, open the OMD-11 enclosure, and check the internal fuses with a multimeter. Replace if necessary with the exact rated fuse. Problem: Fluctuating or Erratic PPM Readings
: 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.
What is the of your specific model (24V, 115V, or 230V)? deckma omd11 manual
The is a widely utilized oil-in-water monitor, specifically engineered for measuring bilge water content to ensure compliance with international maritime regulations . Accurate installation, operation, and maintenance of this device are crucial for preventing marine pollution. The OMD-11 Bilge Alarm Unit, produced by Deckma Hamburg GmbH, meets the strict IMO Resolution MEPC.60(33) requirements.
The OMD-11 is equipped with to provide a margin of safety. The manual details the exact procedure for adjusting their parameters using the front panel buttons: Check the main switchboard circuit breaker
| Specification | Value | | :--- | :--- | | Range | 0-30 ppm (trend indication to 50 ppm) | | Accuracy | To IMO MEPC.60 (33) | | Output Signal | 0 (4) - 20 mA, selectable | | Sample Temperature | +1° to 60° C | | Power Supply | 24 Volt AC/DC; other voltages on request | | Protection | IP 65 | | Dimensions (W x H x D) | 175 x 190 x 220 mm | | Weight | 3.5 kg |
The OMD-11 utilizes advanced optical scattering technology to determine oil concentration accurately. The Optical Measuring Cell Problem: Fluctuating or Erratic PPM Readings : The
Verify the "Zero" reading using clean water; if the display does not show "0", re-adjust the offset in programming mode.
The has explicit "DANGER" warnings.
However, the manual does provide a procedure for an operational using a 100-FTU (Formazin Turbidity Units) calibration fluid. The engineer would apply the fluid and follow a specific sequence requiring the display to show "161" upon successful completion. This confirms the instrument is reading within acceptable parameters.
