: Run clean water through the unit to confirm a 0 ppm reading. 🔍 Troubleshooting Error Codes "EE" Code on Display Meaning : Memory read error or microprocessor failure.
If this lights up, check the sample flow, power supply, and for internal component failure.

For vessels integrating the OMD-11 into a remote alarm system or engine room display, the manual’s Modbus map is gold. It lists registers for:
0 – 30 ppm (linear indication up to 15 ppm, progressive up to 30 ppm). deckma omd11 manual
Signals an instrument malfunction, loss of sample flow, or a dirty measuring tube. Daily Operation and Zero-Adjustment
Wait for the instrument initialization phase to complete (usually a few seconds). Read the current oil content on the digital display. Fresh Water Zeroing (The Clean Water Test)
• Verify sample pump pressure and clear pipe blockages.• Perform the manual cleaning procedure.• Inspect the light source; replace the cell if defective.

Use a soft bottle brush dipped in a mild liquid detergent or a specialized solvent (like petroleum ether).
: If the oil concentration exceeds the 15 ppm (parts per million) legal limit set by IMO regulations, the monitor triggers an alarm. It typically activates a relay to automatically close the overboard discharge valve, redirecting polluted water back to a holding tank. Key Installation & Maintenance Rules | Parameter | Specification | | :--- |
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.
: Features two independent alarm circuits, factory-set at 15 ppm but adjustable between 2 and 15 ppm .
