This alarm indicates that the read data does not mach the original data written.
Cause: [1] Faulty nonvolatile memory
[2] The memory has been rewritten more than 100,000 times.
(As a rough guideline, the nominal service life of the nonvolatile
memory is 100,000 rewrites.)
Action: If the alarm persists after reconnecting the power, contact IAI.
F6 Timeout writing to
nonvolatile memory
This alarm indicates that a response was not received within the specified time
after writing the nonvolatile memory.
Cause: [1] Faulty nonvolatile memory
[2] The memory has been rewritten more than 100,000 times.
(As a rough guideline, the nominal service life of the nonvolatile
memory is 100,000 rewrites.)
Action: If the alarm persists after reconnecting the power, contact IAI.
F8 Damaged nonvolatile
memory
Abnormal data was detected in the nonvolatile memory check upon start.
Cause: [1] Faulty nonvolatile memory
[2] The memory has been rewritten more than 100,000 times.
(As a rough guideline, the nominal service life of the nonvolatile
memory is 100,000 rewrites.)
Action: If the alarm persists after reconnecting the power, contact IAI.
