If the voltage is within the limits replace the Main Control Processor Board.
9.
Remove the power from the system
10.
Disconnect the power cable between the Interface board and Main Control Processor Board.
11.
Check that the connector pins are clean and there is no oxidation. If necessary, lightly clean the
pins with emery paper.
12.
Reconnect the cable and switch on the system.
13.
If the Control Panel continues to reset replace the Main Control Processor Board.
5.2.12
Replace EEPROM
The EEPROM is the flash memory which stores the system configuration data and the Event Log data in
the Graviner Mk6 OMD system.
The EEPROM is device IC17 on the Main Control Processor Board (part number 1-44782-K071-02).
(IC 17)
has reached the maximum number of write cycles recommended by the chip manufacturer and should
now be replaced. The EEPROM device manufacturer guarantees a minimum of 10,000 write cycles.
NOTE:-
This message is advisory only, all other features and functions of the OMD Mk6 will continue to
operate normally and the ability to detect oil mist is not affected.
A read/write failure could mean that recent Event Log data is not stored and any changes made to the
configurable engine parameters may not be saved.
Due to the memory capacity with normal operation of the system it is expected that memory will last
over 10 years before the memory limit is met. Earlier failure of the EEPROM may be due to underlying
faults being recorded in the event log. The event log should be examined prior to replacing the EEPROM.

Replace EEPROM
The action required to remove this warning message depends on the version of the Main Control
Processor Board fitted in the Control Panel.
On earlier versions of the PCB, the EEPROM (device IC17 in the images shown below) is soldered directly
to the Processor board. The EEPROM device cannot be de-soldered without the risk of damaging the PCB
and so requires the Main Control Processor Board to be replaced.
