Guardian Shared
Memory Failure
Indicates that one of the processors on the safety
module has detected a shared memory error. The
shared memory is a section of memory that is
continually passed between the two processors on the
safety module. When the system is started, the
processors go through an initial synchronization to
ensure they will be going through resets at the same
time. After the synchronization, the shared memory is
begun. The shared memory uses a cyclical
redundancy check (CRC) to verify that the memory
remains synchronized throughout operation. If either
the initial synchronization fails, or the CRC fails, this
error will be called. Be aware that this may also
coincide with an invalid reset error. This is a level 2
jam.
Guardian Software
Error
Indicates that one of the processors on the safety
module has detected a software error. This is a level 1
jam and cannot be cleared.
Guardian Stop
Failure
Indicates that a stop was attempted, but was
unsuccessful triggering a stop failure. This is a level 1
jam.
Guardian Test Error
Indicates that one of the processors on the safety
module has called a test error. This is only generated
from the debug menu while bench testing the safety
module. This should never be seen while running in a
live system. This is a level 2 jam.
