11.4 Configuring Multi-Step Ramp/Soak Parameters
11.4.1 Introduction
When the eight-segment ramp/soak recipe option has been selected, several parameters
can be configured that apply to the entire recipe. These include:
• recipe holdback that prevents the setpoint from getting too far ahead of the process
value
• termination state that determines what happens when execution of the recipe has
been completed
• recipe recycle number used to specify the number of additional times the recipe
should be executed once started; this can also be use to set the recipe for
continuous execution
• resume from power failure parameter which controls whether execution of a recipe is
resumed after a power failure
After these parameters that apply to the entire recipe have been configured, you
configure up to eight individual segments.

Each consists of a ramp time, a soak level
(setpoint) and a soak time. In addition, if at least one alarm has been reserved for recipe
event annunciation, you can specify that an available alarm will go on or off when a ramp
time or soak time starts.
The following diagram shows the first few segments of a recipe and the configuration
used to implement the segments.

To configure fewer than eight segments, leave the values of all parameters associated with the un-
needed segments set to OFF or zero.
