5.4 Temperature compensation
5.4.1 Parameter
Temperature
compensation:
With this parameter the temperature compensation can be switched on and off.
-
Range of values: 0, 1
- Factory setting: 0 (off)
5.4.2 Description
The temperature compensation is used to compensate the speed of sound’s dependency on air temperature.
Provided the temperature compensation is active changes in the ambient temperature is compensated to 2%
of So (distance sensor to object). Note: the temperature compensation becomes active not until 15 minutes
after power-on. When temperature compensation is off the sensor provides correct measurements
immediately after power-on. But changing ambient temperature induces a measuring error of 0.18 % Sde/K.
5.5 Locking/releasing of Teach-in button
5.5.1 Parameter
Teach-in lock: With this parameter it can be configured if and when the Teach-in button is
locked.
-
Range of values: 0 (Button always locked)
1 (Button always unlocked)
2 (Button locked 5 min after Power-On)
- Factory setting: 2 (Button locked 5 min after Power-On)
5.5.2 Description
The Teach-in button, which is required to teach the switching point and/or the two thresholds of the switching
window in SIO mode, has been factory set to lock automatically 5 minutes after power-on. This is to prevent
any accidental changes to the sensors’ settings being executed. Whether and when the Teach-in button has
to be locked is configurable in the IO-Link communication mode. Teach-in via Teach-in wire is remains
unlocked. Note: both ways of teaching - via button and via wire - are possible only provided the sensor is in
the SIO mode. Teach-in is not possible as long as the sensor remains in the IO-Link Communication mode.
