When at least one of the semiconductor outputs of the safety device becomes de-energized, then the output contacts revert back to open circuit status. If restart interlock is needed, then this is achieved in the safety device, for example with a C4000 or S3000. External device monitoring (EDM) Category 3 or 4, which determines the performance level ac- cording to EN ISO 13849, requires monitoring of contactors for the detection of failures. This is provided in the connected protective device, for example in the C4000 or S3000. The normally closed contact (Y1 -Y2) in the UE10-3OS unit is a part of this contactor monitoring system. |
