Heating phase

The heating phase describes the time a sensor needs to reach its operating
temperature after start-up. The heating phase is signaled via LED (see Chapter
4.3.1 on p. 20) Parametrization is not possible during the heating phase, all
keys and outputs are disabled..
The heating phase is defined as a combination of a fixed waiting period (t
of 10 s and the sensor's variable heating period of (t
p. 14). That is: t
The duration of heating depends on the sensor's operating temperature and
cannot be parametrized by the user.

Operating elements

Operation and Parametrization of the main functions of the device can be done
via three pushbuttons, "Enter", "Set" and "Mode", on the front side of the device.
The "Enter" button is used to store values and to start the Quick-Teach function.
Because of safety reasons, the pushbutton is recessed and can be pushed
down with a pointed object like a pen.
