7-segment display
In normal operation, the 7-segment display shows the number of the operating mode (1-6). In addition, it
helps during the detailed error diagnostics (see chapter 11) and serves as an alignment aid (see
chapter 8.2 „Aligning the sensor“). In contrast to operating modes 1, 2 and 3, the 7-segment display is
rotated by 180 degrees in operating modes 4 and 6. This is because for many applications, the device
connection is located below the protective field, which is not the case in operating modes 1, 2 and 3.
Table 3.4: Meaning of the 7-segment display
For error diagnostics, the error's respective letter is displayed first followed by the number code. The
display is repeated cyclically. An AutoReset is carried out after 10 s for errors that do not cause locking,
with an unauthorized restart being impossible. In the case of blocking errors, the voltage supply must be
separated and the cause of the error must be eliminated. Before switching on again, the steps taken before
initial commissioning must be repeated (see chapter 9.1).
The 7-segment display switches to alignment mode when the device has not yet been aligned or when the
protective field has been interrupted (after 5 s). In this case, a fixed beam area from the protective field is
assigned to every segment.
3.3.3 Alignment display
Approximately 5 s after a protective-field interruption, the 7-segment display switches to alignment mode.
In this mode, one third of the total protective field (top, middle, bottom) is assigned to one of the three hori-
zontal segments and the state of this sub-protective field displayed as follows:
