Please also see the attached. We have a number of underrollers that are equipped with bumper bars on the left and rights 2 sides of the machine. If one of these bars is activated the machine stops. The status of a bumper bar is detected by a Schmersal safety sensor at each end of the 2 bumper bars. Each of these sensors has 2 switches and these switches are croswired to end in a FDI (safety DI) channel. The signals are used in a safety block. However Schmersal have updated the safety sensors and if we replace both (pair) of sensors on a bumper bar the correct (unactivated) status does no longer reach the PLC. If we only replace one (pair) of sensors on a bumper bar it still works correctly. Schmersal Danish Tech support have investigated and claims that the old and new sensors are the same - except the new ones are assembled with a better glue. Can I adjust the sensitivity on a FDI (safety DI) and if so - where and how do I do it? AttachmentSchmersal.zip (208 Downloads) |
