ratio control
If control of the fan motor is employed for burners with pneumatic air-fuel ratio control,
only the control path is used. There is no need to connect a speed feedback signal and
to have speed control (for operating modes, refer to chapter Selection of operating
mode).
12.13 EMC of LMV37.4... and VSD
The function and EMC tests with the LMV37.4... system have been successfully
conducted in connection with the following makes and types of VSDs:
Siemens: SED2-0.37 / 22 X
Danfoss: VT2807
During operation, VSDs generate electromagnetic interference on the mains network.
For this reason, the supplier's specifications must be strictly observed to ensure that
makeup of the system is in compliance with EMC regulations:
Operating Instructions  installation conforming to EMC
Siemens:
Technical Brochure  radio suppression filter
Danfoss:
Data Sheet on Danfoss EMC filter for long motor cables
Caution!
When using other types of VSD, compliance with EMC regulations and trouble-
free operation are not ensured!
