Method for detecting faults on safety oriented sensors |
摘要 |
A method for fault detection in the operation of sensors with at least two decoupled signal-transmitting elements with contacts and with a closed conductor loop includes delaying, a first test output by a defined switching delay with reespect to a second test output and evaluating the input channels in accordance with a defined expectation. Faults being inferred from deviations between actual and expected signal variations and time intervals.
