8.3.1.1.2 Connection examples that are CONDITIONALLY permitted for areas with a zone 1 explosive
atmosphere
Important note: These connection examples are only permitted if the sensors are "simple
electrical equipment" and the ATEX requirements (e.g. distances between the signal lines)
are observed and maintained.
Connection examples: Digital modes
1 myDatalog2Ex
2 Isolated relay contact
Note: If universal input 1 has to be operated in "Cnt.Day" or "Cnt.Intervl." channel mode, it must be ensured that
the sensor supply is permanently switched on. This can be achieved by setting the warmup time in the "Basic
settings" configuration section (see "Basic setting" on page 80) to a higher value than the record interval.
However, this greatly increases the energy requirements and thus significantly shortens the operating time of the
device.
