eBook: Automating Manufacturing Systems; with PLCs



When a new machine is being prepared for production, or has been delivered by a supplier, it is normal to go through a set of commissioning procedures. Some typical steps are listed below.

1. Visual inspection
verify that the machine meets internal and external safety codes
- electrical codes
- worker safety codes (e.g., OSHA)
determine if all components are present
2. Mechanical installation
physically located the machine
connect to adjacent machines
connect water, air and other required services
3. Electrical installation
connect grounds and power
high potential and ground fault tests
verify sensor inputs to the PLC
4. Functional tests
start the machine and test the emergency stops
test for basic functionality
5. Process verification
run the machine and make adjustments to produce product
collect process capability data
determine required maintenance procedures
6. Contract/specification verification
review the contact requirements and check off individually on each one
review the specification requirements and check off each one individually
request that any non-compliant requirements are corrected
7. Put into production
start the process in the production environment and begin normal use
