Message explanations
A-12 385585/C
Possible
consequences:
There is currently no way of finding out what part of the code has been modified
and if this code is currently in use. Therefore the consequences are unpredictable.
Corrective
actions:
•
If possible, try to change or swap PS (Process Station) with another. If the
error moves with the PS, it should be returned to Kongsberg Maritime
Service for checking/repair (with indication of what processor is failing (given
in parenthesis before the alarm-text)).
•
Contact Kongsberg Maritime Service if this does not solve the problem.
Communication port reservation error
Description: This message shall not occur during normal operation, but is intended to be an aid
for the software engineer during configuration/commissioning.
Corrective
actions:
Should the message occur during normal operation, contact Kongsberg Maritime
service.
Configuration error
Description: This message is reported if there is an error in the system parameter setup or in
configuration files on disk.
The reason for the fault may be erroneous initial configuration or a disk failure.
Additional
information:
•
Failing function.
•
Dependent on function
•
Dependent on function
Possible
consequences:
The DP system may not function properly.
Corrective
actions:
Note the Additional Information and contact Kongsberg Maritime Service.
Switch over to other computer (if any). Restart the failing computer. If the error
persists, switch the failing computer off.
Demand reduced on swbd [#]
Description Power consumption exceeds the limit on this swbd. The computer has calculated
that the necessary pitch/rpm setpoints for the next sample may result in a black-
out condition. A demand reduction has therefore been done.
The method of detection is that the power consumption is calculated and
compared with the actual nominal generator effect. This message is based on
generator feedback and calculated DP power consumption based on the pitch/rpm
setpoints that are necessary to stay in position.
Additional
information
•
Power used by other consumers than DP
•
Power available on this swbd
•
Power used by DP
Possible
consequences
Degraded performance of the DP system.
Demand is reduced on thrusters/propellers to prevent blackout, which again may
result in a position / heading drift-off.
