Based on the specifications of the safety solution, safety experts from SICK create a verification and validation plan. This includes the test points for the verification of the installed physical guards and the safety-related parts of controllers as well as the validation of the functional safety components. The planned tests are then carried out on the machine and logged. This is the only way to prove that the planned safety solution has been implemented correctly and that any safety-critical errors that may exist are corrected in a timely manner. The planned protective measures and safety functions must fulfill the intended protection goals to enable safe operation of the machine.
