Approval - completing commissioning
What is an acceptance?
The machine manufacturer is responsible in ensuring that his plant or machine functions
perfectly. As a consequence, after commissioning, the machine manufacturer must check
those functions or have them checked by specialist personnel, which represent an increased
risk of injury or material damage. This acceptance or validation is, for example, also
specified in the European machinery directive and essentially comprises two parts:
●
Checking the safety-relevant functions and machine parts.
→
Acceptance test.
●
Generate an "Acceptance report" that describes the test results.
→
Documentation.
Supply information for the validation, e.g. the harmonized European standards
EN ISO 13849-1 and EN ISO 13849-2.
Acceptance test of the machine or plant
The acceptance test checks whether the safety-relevant functions in the plant or machine
function correctly. The documentation of the components used in the safety functions can
also provide information about the necessary tests.
Testing the safety-related functions includes, e.g. the following:
●
Are all safety equipment such as protective door monitoring devices, light barriers or
emergency-off switches connected and ready for operation?
●
Does the higher-level control respond as expected to the safety-relevant feedback signals
of the inverter?
●
Do the inverter settings match the configured safety-relevant function in the machine?
Acceptance test of the inverter
The acceptance test of the inverter is a part of the acceptance test of the entire machine or
plant.
The acceptance test of the inverter checks whether the integrated drive safety functions are
set up correctly for the planned safety function of the machine.
