Important for detection of shorts across contacts: As this function for detecting shorts across contacts is not failsafe, it is tested by Pilz during the final control check. If there is a danger of exceeding the cable runs, we recommend the following test after the installation of the device: 1. -
Page 11: Operation
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. Operating Manual PNOZ X2.1C 1003973-EN-07... -
