regeneration cycle step - Internal Software Error
202

407
STATUS RAM
STATUS RAM MEMORY FAILURE - Error generated when the microcontroller can't
operate properly due to corrupted data contained in the Operational Data/Status
Section of RAM memory. When this error is generated, like a "405" or "408" Error,
a "407" is recorded in the Error Log, but the control does not enter Error Mode and
continues to operate normally using previously stored Status RAM data (that can be
up to 6 hrs. old). This portion of memory includes the state of motors, relays, flow,
regen, and more. Most things that are tracked on a moment-by-moment basis that
need to be able to recover in the event of a power loss or reset is saved here.
408
DIAGNOSTIC RAM
DIAGNOSTIC RAM MEMORY FAILURE - Error generated when the microcontroller
can't operate properly due to corrupted data contained in the Diagnostic Section
of RAM memory. When this error is generated, like a "405" or "407" Error, a "408" is
recorded in the Error Log, but the control does not enter Error Mode and continues
to operate normally using previously stored Diagnostic RAM data (that can be up to
6 hrs. old). This portion of memory includes parameters normally displayed in the
diagnostic branch of the menu map.
