Functional Tests - Deckma Hamburg OMD-2008 Instruction Manual

NB: The flow rate should be checked on both, the clean water supply and the
separator sample supply. If the clean water supply is obtained from a high
pressure source, the flow rate will be higher than from the sample point.
The flow rate adjustment is important for the time delay between the sample point
and the monitor. If the sample flow rate is too small, the instrument will be in
Alarm and display "Status: Flow".
On instruments fitted with Manual Cleaning Unit
(OMD-2008 EV-FC MCU), sample a higher or a
lower flow rate can be adjusted. To get the higher
flow rate, remove the smaller O-Ring (9.5x2) from
the Manual Cleaning Unit.

10.3 Functional Tests

a) Run oil free water through the instrument to purge the system
b) Verify that the water is flowing with the proper flow rate trough the
instrument.
c) Switch on the instrument and make sure, that the Power LED is
will change to the standard display, showing the actual measurement.
d) Switch the Clean Water Valve to clean water. While oil free water is
running through the monitor check the Zero adjustment. The display
should be "0" to "2" and the status will show "FW". If the display varies by
greater amounts, it may be that air entrainment is present. If this is the
case, the cause must be located and rectified.
e) If the Zero need to be adjusted, this can be done in the programming
mode as described in section 10.4. (Settings – Offset)
