4.3 Wait operation
If the measured value (PV) has not reached the Wait Zone after the step time has elapsed,
the next step will not start.
However, after the wait time has elapsed, the next step begins.
At the wait operation, the indication at
SV blinks.
: Wait Zone... This means the deviation area between SV(Setting Value) and
PV(Process Value) enable to start next step.

: Wait time... This means the maximum waiting period to start next step when

．．．
Operation will start from the Ramp step including the PV at the starting time of Program operation.
In case more than one step applied, it starts the one with smaller step number.

At these area, operation will not start.
Start operation from this point.
