Message explanations
A-76 385585/C
SysTick Timer/Interrupt error
Description: The reason is probably a failure in the Sys-Tick timer. But the probability of
getting this system alarm reported, is very low, since the whole program system is
executed based on this timer.
Possible
consequences:
Most likely the system has stopped completely if this timer is malfunctioning, so a
report of this error may also be based on an erroneous detection.
Corrective
actions:
•
Replace the PS (Process Station). Note the alarm text, describe the current
operation executed and enclose this data when delivering the PS to
Kongsberg Maritime Service for repair.
•
Contact Kongsberg Maritime Service if this does not solve the problem.
Telegram checksum error
Description: This message is reported if there is a checksum error in a telegram received from
a position-reference system/sensor.
Possible
consequences:
The data in this telegram is not used by the DP system.
Corrective
actions:
Check if there is electrical noise.
Check the serial input interface.
Telegram timeout
Description: This message is reported if an expected telegram did not arrive within the timeout
limit which indicates a fault in the net communication with the position-reference
system/sensor. The reason for the fault may be a problem with the net interface
hardware, for example:
Cable from reference system broken.
Interface - bad connection.
Plug badly inserted.
Broken interface on SBC.
The method of detection is nothing received from the reference system/sensor.
Possible
consequences:
The data from the reference system/sensor is lost. The consequences depend
upon the type of operation.
If the fault relates to a position-reference system, and no other reference system
is enabled, you will get position drop-out after 30 seconds.
Corrective
actions:
If required, enable another reference system/sensor.
Check the reference system/sensor.
Check the cabling and connections.
Replace SBC and check reference system hardware.
