Ramp/Soak
This chapter covers setup and operation of ramp/soak pro-
files in CLS200 series controllers.
These features are available in controllers that have the
optional ramp/soak firmware installed.
The ramp/soak feature turns your controller into a power-
ful and flexible batch controller. Ramp/soak lets you pro-
gram the controller to change a process setpoint in a preset
pattern over time. This preset pattern, or temperature
profile, consists of several segments. During a segment,
the temperature goes from the previous segment’s setpoint
to the current segment’s setpoint.
If the current segment’s setpoint is higher or lower
than the previous segment’s setpoint, it is called a
ramp segment.
If the current segment’s setpoint is the same as the
previous segment’s setpoint, it is called a soak seg-
ment.
