Automatic Program Operation - 65 - FDC MCT-MC
6.1.1 Setting Step Type
Programs are entered as a sequence of steps which define the set point and length of time that a loop should
take to reach the set point (ramp) or remain at a set point (soak). The ramp and soak units can both be set for
hours/minutes or minutes/seconds or one can be set for hours/minutes while the other is set for
minutes/seconds. To begin editing a program step, first select the type of step by pressing the first row in the
list and make the desired selection from the step type pop-up menu.
NOTE: As the step type selection is changed, the list will update to include only the items specific to the
selected step type. This simplifies step entry by only requesting user entry for the items necessary
for proper step operation.
The Ramp selection allows the user to program the loop to ramp to a set point in a specific period of time.
Simply select ramp from the pop-up menu and then enter the loop set point and time.
The
Soak selection allows the user to program the loop to maintain its set point for a specific period of time.
Simply select soak from the pop-up menu and then enter the time desired to maintain the set point.
The
Jump selection allows the user to jump to a previous step in the program and set the number of times
the program should execute the jump before continuing to the following step of the program.
The
End selection allows the user to program the last step of the program. The end step type includes a final
set point (if configured) and a cycle count entry to allow the user to enter the number of cycles the program
should repeat itself if desired.
6.1.2 Setting Step Set Point and Time
Set point entry is only provided when entering a ramp step. If “soak” is selected for the step type, the loop will
remain at the previous set point for the amount of time entered for the step. The set point entered is used as
the target set point for the step, i.e., the set point the loop control will arrive at by the end of the step.
To enter the set point, touch the set point field and enter the desired set point. The limits of entry will be
dependent upon the selected primary loop under the Program Operation window Settings. To enter the step
time, touch the time field to enter in the desired time duration. Time is entered as HH.MM or MM.SS depending
upon the selection made on the Time setup screen under the Edit icon pop-up menu. Thus, to enter a time of
1 hour for example, you would enter a value of 1.00 for one hour and zero minutes. To enter a step time of 30
minutes, the time entry would be made as 0.30 for 30 minutes. If the time selection was in minutes and seconds,
an entry of 1 minute and 30 seconds would be made as 1.30.
