The screen will automatically change to the Start screen. By default, a program will always start on step 1. If
you wish to start the program on a different step, press the start step field and enter the desired start step or
use the left and right skip buttons to adjust the step number.
Select the desired loop to download and start the program on using the drop down selection. If only one loop
is configured in the system, or the program mode is set to “All”, the loop selection will not be visible. When
the program mode is set to “All” on a multi loop system, program operation is automatically defaulted to the
primary loop.
Once the desired loop has been selected and the start step number is entered, press the “Start” button. The
program will then be transferred to the loop control and started once the transfer is complete. The Status
screen will then be automatically displayed.
To stop
a program, select “Stop” from the Program menu. When a program is stopped, the loop set points
and events will revert back to the single set point (static mode) values that were entered prior to the program
being started.
NOTE: When the program operating mode is set to “Single” and more than one loop is configured in the
system, the “Halt” menu selection will prompt the user to select a loop to perform the action on prior
to stopping a program. If only one loop is configured, or the program mode is set to “All” on a multi
loop system, the program will be stopped on the primary control loop.
Hold/Resume Ramp/Soak Program Operation
At any time during the operation of a program, it can be manually placed into hold. This stops the program
timer; however, the display continues operation under the current step settings at the time the program was
put into hold. To pause a program, select “Hold” from the Program menu. To resume the program from the
point in which it was paused, select “Start” from the Program menu.
NOTE: When the program operating mode is set to “Single” and more than one loop is configured in the
system, the “Hold” menu selection will prompt the user to select a loop to perform the action on prior
to placing a program in hold. If only one loop is configured, or the program mode is set to “All” on a
multi loop system, the program will be placed in hold on the primary control loop.
