²) In case of failure, the leakage current at the most flows to the OSSD
cable. The downstream control element must recognise this state as
LOW. A safety PLC must detect this state.
2.6 Response time (reaction time)
The response time depends on the hight of the protected field, the
resolution and the number of light beams.
