l
Data write was
executed outside of
the allowed setting
range.
l
The written data is retained as is.
l
In case of the mode select item, the operation is
executed using the data prlor to the write operation.
l
When the value exceeds the upper or lower limit in
temperature, time, or percentage setting, the control is
performed with the upper/lower limit value.
l
The address where the error occurred is stored.
l
When the write operations were executed to multiple
write areas, the address where the error was first de-
tected is ratained.
l
Write data within the
allowed setting range.
(The error is reset when
the data within the al-
lowed setting range is
written.)
5
l
Setting of the up-
per/lower output
limiter or the up-
per/lower setting
limiter is invalid.
l
The written data is retained as is.
l
Allowed upper and lower values are used for the
control.
l
The address where the error occurred is stored.
l
When the write operations were executed to multiple
write areas, the address where the error was first de-
tected is ratained.
l
Modify the upper/lower
output limiter and the
upper/lower setting
limiter so that the lower
limit value is less than
the upper limit value.
6
l
The set value was
modified during the
default setting
registration.
l
The written data is ignored.
l
Modification of the set value is not allowed until the
error is reset.
l
The address where the error occurred is stored.
l
When another write error occurs, the error code does
not change but the error address is overwritten by the
address of the new write error.
l
Modify the set value
after the error reset
(Y12 : ON).
Remark
1) *: When the data beyond the setting range is written in the input range
area or in the alert mode area during the setting mode, the error code “4”
is stored.
When it is changed to the operation mode without resetting the error, the
error code is changed to “3”.
In this case, execute the error processing for the error code ”3”.
2) Priorities of the errors are as follows :
When a high-priority error occurs while a low-priority error has already
occurred, the error code and the error address of the high-priority error
write over those of the low-priority error.
[Priority]

(Between the errors 2 and 4, the error with the lower error address has priority.)
