6.3 Multifunction input/output
The MF multifunction input/output can optionally be deactivated, or configured as an input or output.
MFIO/MFIn input functions:
•
Teach-in
•
Switching off the send LED (test)
•
Reset counter value
•
Reset extreme value memory
MFIO/MFOut output functions:
•
Operational safety alarm (Quality of Run Alarm)
•
Digital output channel 1
•
Response signal for successfully performed teach-in(feedback)
•
Error mode for signal when the measured value is outside the set range.
6.4 Wiring the digital input
The digital input can be used to start a teach-in, to switch off the sender as a test input, for an external input
signal (Smart Task), or to reset the counter value (Smart Task). Voltage level at the input starts the corresponding
function of the sensor.

6.5 Wiring the digital outputs
The number of digital inputs available at the connections will vary depending on the sensor, see "Connections",
page 14. If the allocated event occurs in the read process, then the corresponding digital output is live.
In each case, the digital outputs are short-circuit protected and overcurrent protected. The switching behavior is
selectable: push-pull, PNP or NPN (open collector).
