Entering a Ramp/Soak Program
Ramp/Soak programs are created and edited from the program Entry screen. The program Entry screen can
also be accessed directly from the “Program” menu. To create an automatic ramp/soak program:
1.)
From the File menu, select “New” to create a new program.
2.) Enter the number of steps that will be in the program you want to create. The default setting, and
minimum number of steps is two. You can only adjust settings for step numbers within the range of 2 to
the Max Steps entered (maximum of 64). Thus, to adjust settings for step 5, you must have the Max
Steps set to a value of at least 5.
NOTE:
The number of steps can be changed at any time during the program entry to shorten or
lengthen the program as required without affecting steps already programmed.
3.) For each step, enter the step events, set point(s) and time duration or ramp rate (depending upon the
ramp units selection). Example shown below with step time (HH:MM).
4.)
From the File menu, select “Save” to save the program.
NOTE:
Programs can be saved with names of up to 16 characters long. However, the display only uses
the first 14 characters of the program name for display updates and record keeping. When
naming programs, try to keep the name limited to 14 characters in order to have the full program
name shown, or use the first 14 characters as a means of more clearly identifying the program
when more than 14 characters are used in the name.
The
Ramp
units selection is a global selection that applies to all steps of the program. It allows the user to
select the method of ramp step entry. Selections include ramp entry in units of time as either hours and
minutes (hh.mm) or minutes and seconds (mm.ss) and entry in rate of change as units/hour or units/minute.
The
Soak
units selection is a global selection that applies to all steps of the program. It allows the user to
select the method of soak step entry. Selections include units of time as either hours and minutes (hh.mm) or
minutes and seconds (mm.ss).
The
Hold
band entry is global setting that apply to all steps of the program. If holdback is enabled on a ramp
or soak step, this value will by applied to the current set point to determine if the process value is within the
allowed deviation from set point. If outside of the allowed deviation, the program will be automatically placed
into hold until the process value recovers within the band.
