Timing Description
(1) The Program Start parameter was changed from RSET to STRT using either an event or key operations.
The RUN/STOP status automatically changes to RUN mode when the above operation is performed.
(2) The Program Start parameter was changed from STRT to RSET using either an event or key operations before
the soak time expired.
The RUN/STOP status automatically changes to STOP mode when the above operation is performed.
(3) The Program Start parameter is again changed from RSET to STRT using either an event or key operations.
The RUN/STOP status will automatically change to RUN mode when the above operation is performed.
(4) The RUN/STOP status automatically changes to STOP mode when soak time expires.
END flashes on the No. 2 display and the program END output turns ON.
(5) The Program Start parameter is changed from STRT to RSET using either an event or key operations.
The END display is cleared and the program END output turns OFF.
(6) Key operations are used to switch the RUN/STOP status to RUN with the Program Start parameter configured
to RSET (stopped).
Normal control operation is started.
(7) The Program Start parameter is changed from RSET to STRT after the process value stabilizes.
The RUN/STOP status remains as RUN.
(8) Key operations are used to change the RUN/STOP status to STOP (during program operation).
Measuring the soak time is continued within the wait band. (Measuring the soak time stops when the process
value leaves the wait band.)
(9) Key operations are used to change the RUN/STOP status to RUN.
Measuring the soak time is continued within the wait band (continuing from the time between (7) and (9)).
(10) The RUN/STOP status automatically changes to STOP mode when the measured time reaches the soak time.
END flashes on the No. 2 display and the program END output turns ON.
