4.8 Setting the limits
Note: In order to use the limits, it is necessary to configure the relay outputs
accordingly.
 Section 4.7
Up to two limits, with upper and
lower thresholds, can be pro-
grammed.

Figure 15
If the reading reaches the upper
threshold , the limit is activated; it
remains activated until the read-
ing falls back below the
lower
threshold .
On the dual-angle instrument, it is
also possible to make a setting for
each limit indicating whether it
should react to the 90° or the
25° reading.
