Variable frequency inverter controlled pumps/mixers

In installations utilising variable frequency inverters for

speed control of pumps, interference from a variable

frequency drive (VFD) may cause nuisance tripping of

monitoring equipment and the electronic sensor CLS.

VFD-interference does not affect FLS and FLS10.

Interference occurs when the pilot cores are in close

proximity to the power cores.

The interference may be suppressed by connecting a

suitable filter

between the monitoring conductors (T1,

T2) and ground (PE).

The filter should ideally be situated in the pump/mixer

junction box.

Cables containing both power and pilot cores should

be kept to a minimum length.

The power cable and control cable should be run in

separate cable ducts with a distance of at least

300 mm between them.

Our pumps are CE-marked according to EMC-direc-

tive and the VFD that we buy from a subcontractor

should also be CE-marked. In order to make the VFD

pass the EMC-tests the interconnecting cable be-

tween pump and VFD has to be screened.
