Wind difference
See “Sensor difference”.
Wind not enabled
See “Sensor not enabled”.
Wind sensor height inconsistency
Description: Wind sensor height above sea level is not valid. Used draught may be incorrect.
No height compensation on wind speed is performed on this sensor.
The method of detection is a check on draught settings, and wind sensor height.
The reason for this fault may be that the draught measurement (or input) is
wrong. It can also be that the wind sensor height is not configured right.
Additional
information:
Sensor number (1, 2, 3, ..)
Possible
consequences:
Wind compensation may be inaccurate.
Corrective
actions:
Investigate draught and wind sensor. Correct draught. If wind sensor is in use
change to a different sensor.
Zero pointer usage (see message)
Description: BITE (Built In Test Equipment) has discovered that in some part of the SW, a
zero-pointer has been utilized to execute a memory write instruction in the
address area below 0x500 (normally an overwriting from address 0x0 and
upwards).
Possible
consequences:
This is a serious system-error, since the lower address-area is normally used for
system-purposes, and must not be used by application. The reason for this type of
error is probably an improper or missing zero-pointer test in some of the software.
The system information in the lower address-area is normally self-reinitialized, but
the functional consequences of a zero pointer usage are unpredictable.
The PS (Process Station) will probably stop.
Corrective
actions:
•
As indicated in the alarm-text, some extra information about the overwriting
is found in a system message received simultaneously as the alarm. Write
down the event-text, describe the current operation executed and what
processor is failing (given in parenthesis before the alarm-text), and report
this to Kongsberg Maritime Service.
•
It is also possible that this type of error is caused by a HW component error.
If possible, try to change with another PS (Process Station). If the error
moves with the PS (Process Station), the failing PS should be returned to
Kongsberg Maritime Service.
•
Contact Kongsberg Maritime Service if this does not solve the problem.
