7.2 Function test of the relay outputs
When the relay outputs are switched on, the mechanical contact on the relay cannot be
tested automatically. Depending on the operational environment, measures to detect the
non-opening of switching elements may be required under some circumstances.
When the product is used in accordance with the European Machinery Directive, a check
must be carried out to ensure that the safety contacts on the relay outputs open correctly.
Start the device again or open the safety contacts (switch off output), so that the internal
diagnostics can check the correct opening of the safety contacts
