Switching Inputs EXT (X41) 38 Switching signals As soon as the trigger points defined in parameters are reached, the corresponding outputs (pins 15,16) are activated. You can set up to two trigger points. The switching point “zero” has a separate output (see “Zero crossover”). Signals for sorting and tolerance checking If the sorting limits defined in parameters are exceeded, the corresponding outputs (pins 17, 18) are activated. Signals Operating parameters Pin Switching signals P62, switching limit 1 15 P63, switching limit 2 16 Sorting signals P18, lower sorting limit 17 P19, upper sorting limit 18 Zero crossover The display value “zero” activates the corresponding output (pin 14). Minimum signal duration is 180 ms.

Switching signal for errors The display unit permanently monitors functions such as measuring signal, input frequency, and data output, and displays an error message if it detects an error. If errors occur that seriously influence measurement or data output, the display unit activates a switching output. This feature allows monitoring of automated processes.
