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.
