Input checks consist of all the electrical components that send an input to the Plc being manually forced to check that the Plc is receiving the signals.
Output checks consist of all the electrical components that are operated by the Plc are forced by the Plc to check that the components are operational and that the Plc is sending out the signal.
Shakedown is the first time the machines run once all the checks have been completed, its purpose is to make sure all connections are tight and haven’t become loose in transit.
Dry Run is the final test of the machine before handover, it lets the customer see the machines run consistently without product and prove that there are no serious issues with the installation. Current, Speed and Temperature readings are taken at regular intervals to make sure there are no irregular readings.
Once Dry Run is complete the machines are ready to run product and we hand over the machines to the customer.
