Ramp/soak profile example
Before you perform the actual configuration, we recommend that you draw a Ramp/Soak
profile in the space provided on the "Program Record Sheet" (Figure 4-4) and fill in the
associated information. An example of a Ramp-Soak Profile is shown in Figure 4-3.
Start setpoint is at 200 degrees F.

ENABL = When the program is initially changed from HOLD to RUN the
present PV value is captured and used as the beginning setpoint
value for the ramp segment. If the program is terminated before
completion, the setpoint value will revert back to the PV value
captured at the initial HOLD to RUN transition. If the power is
cycled before program completion, upon power-up the setpoint is
set to the PV value at power-up and when the program is restarted
that setpoint value is used initially.
The program state selection determines the program state after completion.
The selections are:
• DIS = program is disabled (so program value changed to DIS)
• HOLD = program on hold
The program termination state function determines the status of the controller
upon completion of the program.
The selections are:
• LAST = controls to last setpoint
• FSAF = manual mode and failsafe output.
When enabled, this selection allows you to reset the program to the beginning
from the keyboard.
