1) Principle of wiring
The fan MUST always be grouned.
We advise the use of armoured
cable for the inputs/outputs signals
2) Wiring diagram
See appendix.
The start/stop of the fan must be activated with entries K1/K2/K3 (softstop ) and not via power supply 230V.
3) Working modes
The control box CB1 TAC3 FULL allows to operate in 4 different modes :
CA MODE:
The user defines 3 constant airflow instructions m³h K1, m³h K2 et m³h K3.
These are activated using entries K1/K2/K3
LS MODE:
The requested airflow is a function of a 0/10V signal connected to entry K2 (linear link).
The user defines the link by giving 4 values: Vmin, Vmax, m³h≡Vmin et m³h≡Vmax.
Principle :
CB1 TAC3 FULL
Value m³h≡Vmin can be smaller or greater than m³h≡Vmax.
Note: in « advanced setup » it s possible to stop the fan when the signal is
lower or higher than set value.
Installation manual
The black plastic covers (1) have
to be put on the motor connectors
(2) as shown below.
