Do you have any idea why they should fail ? On the attached diagram I can actuate K1 by bridging contacts 8 & 9 on the DIN rail. There is 12 volts across 5 & 9 and 6 & 10. They where working but the system has been sat idle for some years. I have replaced S3, S4, K2 and K3.Photoelectric sensors

Hi
Diagram looks not well excplicit
Did you check proper status of the Diode ?
What you mean by fail ? Are these sensors for displacement of the crane ( or safety ..purposes )
There is 12 volts at 9 & 10 so I'm not clear on what the diode between 11 & 12 is/isn't doing.Hi

As drawing not so clear to read Diode may be defective and cause an "open circuit " instead of let passing current to activate a relay for exampleThere is 12 volts at 9 & 10 so I'm not clear on what the diode between 11 & 12 is/isn't doing.
