Display On The Rc (Remote Control); Fan Failure Alarm - aldes DFE Série Manuel D'installation Et De Maintenance

4.4 Display on the RC
a) Standard display
By default, only airflow and fan pressure values as well as alarm status are displayed on the LCD.
b) Display all the parameters
Press on the left knob on the diagram so that the SETUP LED ignites
↑ ↓
By pressing and it is possible to display the status of all the working parameters:
- DFE type
- working mode and set values
- Airflow/pressure of each fan
- Pressure alarm setup (CA/LS working mode only)
- Alarm status
- Status of K1/K2/K3 inputs on the CBr
- Status of the bypass
- Status of the anti-freeze protection
- T° values of sensors 1/2/3

4.5 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)

4.6 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.
