Operating instructions
The OMD-2008 EV has an electric switchover valve to switch over from sample
water to clean water. Whenever clean water is used, the instrument will be in
Alarm condition.
The OMD-2008 EV-FC has an additional Flow Sensor to detect the flow rate of
the water through the instrument. If the sample does not flow, the instrument
will be in alarm condition.
The OMD-2008 EV-FC MCU has the Flow Sensor, and additionally it has the
Manual Cleaning Unit.
Instrument start-up sequence:
a) Switch on the power supply.
b) Allow a period of time for water entering the sample tube.
c) Switch the Electric Valve to clean water stream and let oil free water flow
through the system for a few minutes. Check that the display shows 0 to 2
ppm. If not, clean Measuring Cell sample Glass Tube properly.
d) Switch the instrument back to sample stream from to the separator sampling
point connection.
e) The instrument is now ready for use.
11.1 Operator Notes
a) When oily water flows through the instrument the display will show the actual
value of oil content.
b) 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.
