OMD-2008 Series Operating instructions

When oily water flows through the instrument the oil content will be measured and the
display will show the actual value of oil content.
If the oil concentration exceeds the adjusted threshold (works adjustment 15 ppm), the
alarm indicator 1 will be illuminated in intervals during the selected time delay before it
changes to steady light and the associated alarm relay will operate. Accordingly, also the
alarm indicator 2 will be illuminated and its associated alarm relay will take the
appropriate shut down action.
Whenever the instrument is switched over to FW, it will be in alarm condition, too, as
required by IMO.
Additionally, alarms, oil content and separator status will be recorded in data logger to
IMO Requirement every 15 seconds.
To switch over from sample water to clean water is depending on the instrument.
The OMD-2008 is equipped with a manual valve to switch over from sample water to fresh
water (See Figure 28. Operating Instructions OMD-2008).
Do not use excessive force to operate the handle. The OMD-2008 will only allow
overboard discharge in Normal Operation setting of the valve handle.
