WARNING
To achieve SIL3/Cat.4/PLe using this wiring, you must use a suitably qualified sensor.
Note
1L+, 2L+, and 3L+ can be fed from one power supply. The maximum permitted common
mode voltage U

Diagnostics using the LED display
The F-SM indicates faults by means of its SF LED (group fault LED). The SF LED is
activated when the F-SM generates a diagnostic message.
The SF LED flashes as long as a cleared fault has not been acknowledged. It goes dark
when all faults have been eliminated and acknowledged.
The SF LED flashes until you acknowledge passivation following a module fault.
