Message explanations
385585/C
A-11
Corrective
actions:
Recalibrate the reference origin by disabling all reference systems, and then
enabling the required origin reference system (may be the same as used before).
Set the correct UTM zone for UTM position reference system(s).
Calibration OK
Description:
This message is reported if a position reference system is successfully calibrated
into the system.
The measurements from this reference system was sufficiently stable during the
calibration period to be accepted. Low-pass filtered values are used as
transponder coordinates relative to the reference origin system.
Additional
information:
•
Transponder coordinate north
•
Transponder coordinate east
Possible
consequences:
The DP system will start using this system for positioning.
Checksum error (see message)
Description:
This message shall not occur during normal operation, but is intended to be an aid
for the software engineer during configuration/commissioning.
Possible
consequences:
The system might not function properly.
Corrective
actions:
•
Check configuration.
•
Should this message occur during normal operation, contact Kongsberg
Maritime Service.
Clock failure
Description:
This message is reported if the values read from the real time clock (in the PS
(Process Station)) was outside accept-limits (for example, hour is negative or
greater than 24).
The reason may be an error in the real time clock chip or a battery failure.
Possible
consequences:
Error messages (also this one) will have incorrect date/time.
Corrective
actions:
Replace the real time clock's battery.
Replace the real time clock or replace PS.
Code checksum difference
Description:
When loading the SW at PS-reset (Process Station), the checksum is zero. During
normal execution, the BITE (Built In Test Equipment) system calculates, at cyclic
intervals, a new checksum to compare with the first one. If there is a difference, it
means that, from the processor point of view, the SW code has been modified
since the last reset/loading. This could be caused either by a SW error, or a HW
component error.
