Emergency mode
Not editable with step switching (see also chapter 4.4.1 “
In case of a failure of the signal source of installed fans, there is an emergency function in the EC
fan. It is independent of the TCS or upstream controls and must be activated (parametrized) in the
EC fan. The electronics integrated in the fan monitor the bus communication and the signal level of
the analogue signal.
If the bus communication or the analogue signal breaks off and takes longer than the set time (4.4.13
“Emergency delay”
), the emergency speed is activated by the internal electronics in the fan. The
height is specified in the following parameter: 4.4.12 “
Emergency mode when monitoring the analogue signal can then only take place with control
via 2 ... 10 V. If the analogue signal falls below 1.9 V, the emergency speed is activated after
the set waiting time.
Possible settings:
OFF
