Chapter 8 Installation
8.3.1.1.3 Connection examples that are NOT permitted for areas with a zone 1 explosive atmosphere
Connection examples: Digital modes
1 myDatalog2Ex
2 Sensor with open collector output
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.
