Flowserve OR 52-7 - Manual (Page 23)

The memory card is on the CPU circuit board in the housing lid. Fig. 7. The design of the card ensures
that the recorded time, date, alarm, malfunction and status messages are stored for 8 months as
required by the IMO Resolution MEPC 07 (49).
Once the capacity limit of the card is reached, the oldest message will be overwritten, which means
that the card does not have to be exchanged.
The memory card is encoded with the serial number of the associated oil & turbidity detector OR 52-7
and, as a consequence, only this particular device can write data on the card. All other devices are
only able to read the data stored on the card.
Memory Card
Note
When replacing the oil & turbidity detector OR 52-7 make sure that the memory card
remains on board the ship because it contains the proof that the requirements regarding
oil separation as stipulated by the IMO Resolution were fulfilled.
To take the card out of the card holder unscrew the card locking piece
&, Fig. 7.
According to the IMO Resolution MEPC 07 (49) the time, date, alarm, malfunction and status
messages must be stored for 8 months. The measuring transducer features therefore a data logging
function.
The state of the equipment (Log MSG: Oil content, Alarm 2, Clear Water and Separator) and, in addition,
every change of state (State change: ON/OFF Alarm 2, geographic position, Clear Water and Separator)
are saved every hour.
