Note (1) The bank number can be changed even during program operation by using
either an event input or key operations.
(2) The bank number is initialized to 0 when the program pattern is changed.
(3) Even if an event input assigned to "Program Start" is switched from STRT
to RSET while the power is OFF, the RUN/STOP status will not be
changed when the power is turned ON and the bank number will not be
initialized to 0.

The wait band is the band within which the process value is stable in respect
to the set point. The soak time is measured within the wait band. The timer
that measures the soak time operates only when the process value is within
the wait band around the set point (i.e., SP ± wait band). In the following diagram,
the timer will be stopped between the start and (1), (2) and (3), and (4)
and (5) and will measure the time only between (1) and (2), (3) and (4), and
(5) and the end.
