Common Questions About Ramp/Soak Program Operation
1.
How do I start or run a ramp/soak program?
To select and start a program, you must be on the ‘Entry’ or ‘Status’ screen. Using the File menu, choose the
‘Open’ menu item to select from a list of all available programs stored on the display. Open the desired
program from the list, and then select ‘Start’ from the Program menu. Enter the desired start step and select
the loop to start the program on, then press the ‘Start button.
2.
How do I know which program is running?
When a program is running, the name is displayed on Status view screen as well as the Single and Overall
loop view screens. the display will indicate that the program is running when it is in operation. If a program is
not running, the display will display the name of the currently loaded program, i.e., present in memory and
ready to be run.

Why is the program not running to the set point entered for the step?
Automatic ramp/soak program operation is limited by the lower and upper set point limits (see section 8.3
Setpoint Limits). If a program step has a set point that exceeds the lower or upper limit, the set point will be
automatically coerced to the limit it exceeds. This prevents damage to equipment or product by insuring that
the system only operates to the range entered by the user. If a program step has a set point of 100 for
example, but the upper limit is 90, when the program is run the set point will be coerced to the maximum
allowed upper limit of 90 during operation of the step.
The original program remains unaltered, so if the user then changes the lower and upper limits to match the
range of set points within the program, the program will then operate to the programmed set points. This
insures that the operating range of the system can not be exceeded even if a user accidentally copies a
program from another system with a greater operating range.
