Running Your Series 920
To run the Series 920, you must be at one of the three main level operating parameter
menus, SYSTEM, PROGRAM, or SETUP. Press the RUN/HOLD key. The Series 920
asks you what file you’d like to run, and asks what step to begin with. After entering
the file and step number, the program begins and the RUN LED is lit. While in the
RUN mode, you can only view the current file and step.
To change your program, you must be in the HOLD mode. To stop your program
at
any time, press HOLD. When returning to your program, the Series 920 asks if
you’d
like to
RESUME? on the step you left off on. Trying to RESUME on a file that has
been changed, generates an “ER2 0040”; this is a “Change File Error.” Advance to
the START prompt and begin the program again.
When in the PROGRAM menu, SP is programmed to the steps ending set point.
When in the RUN mode it shows the current set point. In the RUN mode, SE shows
the
steps ending set point. Refer to Pages 51 - 52 for definitions of other prompts.
