5 SIO mode
The yellow LEDs indicate the switching status of the sensor�
5.1 Switching function normally open
Transistor output
LED
yellow
Switched (conducting)
On
Rotational speed > SP + Hy and during the start-
up delay
Not switched (non
conducting)
Off
Rotational speed < SP
SP = switch point
Hy = hysteresis
5.2 Switching function normally closed
Transistor output
LED
yellow
Not switched (non
conducting)
Off
Rotational speed > SP + Hy and during the start-
up delay
Switched (conducting)
On
Rotational speed < SP
SP = switch point
Hy = hysteresis
6 IO-Link mode
IO-Link allows the configuration of internal parameters such as start-up delay
and switching behaviour (normally closed/normally open) as well as reading the
current measured values� Furthermore IO-Link protects against signal faults and
measured value losses as well as tampering with the device�
You will find the IODDs necessary for the configuration of an IO-Link device and
