4.4 Fan failure alarm

It is possible with a SAT3 mounted on the CBr (option) to provide the fan status (control if actual delivered airflow >
20% of airflow assignment) or if they are stopped, using the R3 relay of the SAT3. This feature provides an
increased safety with regard to the start instruction control, because there is a control on the fact that the fan is
actually running (closed loop principle)

4.5 Actual airflow / pressure output signals
A 0-10V signal representing the actual airflow or the actual pressure delivered by one of the selected fans with a
linear relation is a standard feature. The output signals are located between terminals OUT1/OUT2 and GND on the
CBr module.
Default setup : OUT1 = airflow fan 1 (supply fan) and OUT2 = pressure fan 1 (supply fan).

Via the 'advanced setup' it is possible to connect any of these 2 OUT signals to the airflow or pressure value of any
fans.
