6.4 Operation
In order to ensure the proper functioning of the fan, the following must be checked regularly:
– Formation of dust or dirt deposits in the casing or on the motor and impeller
– Freewheeling of impeller. Wear protective gloves when checking freewheeling of impeller!
– Occurrence of excessive vibration and noise
If excessive vibration or noise occurs, maintenance must be carried out according to the instructions in chapter 8.
7.0 Functional description SKR../KR..
The rectangular centrifugal fans SKR../KR.. are speed controllable by means of voltage reduction. Power adjustment
through voltage reduction can be carried out using phase control devices or transformers (TSW/ TSD...). When using
electronic actuators or controllers (ESU../ESA… , ESD...), electromagnetic motor noise (humming) may occur in the low
speed range. This is not the case when using transformer controllers. With regard to noise-critical installations, this
solution is preferred.
NOTE!
In order to ensure sufficient motor cooling, a minimum speed/voltage, which also depends on on-site resi-
stances, wind pressure, etc., must be observed.
When dimensioning the control units, it is important to note that current peaks can occur within the controlled voltage
field. The control units must therefore be dimensioned according to our technical specifications.
Suitable control units are offered as accessories.
Three-phase fans are suitable for operation with frequency inverters with integrated sine filters (Helios
type FU-BS or FU-CS). The frequency inverter settings can be found on the fan type plate.
NOTE!
The use of third party products, especially other electronic devices, can lead to functional problems, the
destruction of the controller and/or fan. If control units are used, which have not been approved by Helios, all
warranty and liability claims shall lapse.
