<How to Check>
By following the steps (1) through (4) shown below, the "Sequence" in which the error has occurred can be checked in addition to the
type of the mechanical error.
(1) First of all, check the "Sequence" that matches the data (1), referring to "Address" in the mechanical error applicability table.
(2) For the applicable "Sequence" in 1 above, if S reel error detection sensitivity level (CEh or 8Dh) is listed in the "Sreel" subfield of
the "Mecha Error" field, compare it with the data (2). If the data (2) is above the S reel error detection sensitivity level listed, the
error history indication should be "S reel error".
(3) For the applicable "Sequence" in 1 above, if T reel error detection sensitivity level (CEh or 8Dh) is listed in the "Treel" subfield of
the "Mecha Error" field, compare it with the data (3). If the data (3) is above the T reel error detection sensitivity level listed, the
error history should be "T reel error".
(4) Unless S or T reel error is determined in step 2 or 3 above, the error history should be the error condition specified in the "Mechani-
cal Error Applicablity Table" field marked with
Note : If a multiple number of items are specified, any of the applicable items should have occurred.
The DEW errors can be identified according to whether or not there is dew indication at an occurrence of an
error.
* The reference table of actual mechanical errors is given at the end of Chapter 3. (See "7: Mechanical Error
Table" on p. 3-21.)
