Functional description RR EC

The centrifugal in-line fans RR EC are steplessly speed-controllable by means of 0-10 V control voltage. Sui-
table potentiometers (Type PU/A 10), three-step switches (Type SU/A) are offered in the Helios accessories range.
Stepless speed control is possible with the universal controller (Type EUR EC). Alternatively, the electronic
differential pressure/temperature controller EDR / ETR can be used.
m
Activation / deactivation:
EC fans can be frequently activated and deactivated via the 0-10 V control input or the release input
depending on the type . This is gentle on the electronics and ensures a long service life . Control via the
power supply (on/off) is not recommended . In general, there must be an interval of at least 120 seconds
between activation and deactivation .
m
In case of strong vibrations and/or odours, maintenance must be carried out by a specialist according to
chapter 1 .4 .
5 .0 User maintenance
The centrifugal in-line fans RR EC are maintenance-free, there are no user maintenance provisions.
