6.7 Running (Executing) a Program
To start program execution, the beginning program step of the program to be run must be displayed. Displaying a specific program step is covered in Section 6.3.
With the first step of a program displayed, press <START/STOP> to begin program execution at that step. The program will continue to execute until it
reaches program step 100 where it will display end and wait for action from the operator.
Running programs may also be stopped at any time by pressing <START/STOP>. After a program has been stopped in this manner, pressing <START/STOP> again will cause the program to continue executing from the beginning of the step it was executing when it was stopped. Important: If the refrigeration compressor was on when the program execution was interrupted in this way, it will be restarted when program execution is restarted.
At the end of a program, the controller will not turn on further heat or cool, however, the chamber blowers will remain on unless blower shutoff mode has been enabled(see Section 8.5). The blowers can be turned off manually by an operator using the front panel mode switch. Set the switch to OFF to turn off the blowers. The refrigeration compressor (mechanically refrigerated models only) will be turned off when a program completes.
IMPORTANT: If you are controlling an chamber or platform with optional solid state relay power control, including units with compressor control, please read Section 6.8.4 at this time.
CAUTION: Chamber temperatures can exceed 70°C, without heaters energized, if high velocity blowers have been installed. If this presents a problem, be sure the test load is removed promptly at the end of the program run, or enable blower shutoff mode (see Section 8.5) to have blowers not run on at the end of a program execution.
