132 Starting Up Your Control System
8. Conduct a Dry Run
After thoroughly checking out the controller system and program,
proceed with a dry run of the application with all of the output
devices enabled. This dry run will vary with the application. A
machine tool dry run would test the program with all outputs enabled
but without tooling an actual part.
After you check out the entire system, and your dry run has been
completed satisfactorily, we recommend that you load your program
into an EEPROM memory module for back-up program storage. Refer
to your programming software’s online help for directions on loading
the EEPROM from RAM.
This step completes start-up procedures. Your SLC programmable
controller is now ready for operation.
ATTENTION
During all phases of checkout, station a person ready to
operate an emergency-stop switch if necessary. The
emergency-stop switch will de-energize the master control
relay and remove power from the machine. This circuit must be
hardwired only, it must not be programmed.
