3.5 « FAN ON » signalization
By default, R3 (O.R.2) relay of SAT3 (option) provides the fan status (running or stopped):
-
For fans with speed feedback: control if actual delivered airflow > 20% of assignment.
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).
- For fans with run contact, the FAN ON status will be delivered when the contacts of all the
fans that must turn will be closed.
It is possible to configure the signalization on O.R.1 or no signalization at all.
