SFC VSS
SFC 0.75-15 Hp
General
This manual is a quick aid for easy programming of the
frequency converter together with the rotary switch SFC
VSS and shall not be seen as a complete product manual.
Function
All programming is executed on the keys at the front display
Fig. 1. The jog dial (1) is used for navigating the menus and
to select or confirm information. The ESC key (2) quits a
menu/parameter or clears and reverts the value. The front
panel is opened via button (3).
Electrical wiring
The supply voltage is connected to terminal (6) Fig 3. The
supply cable for the fan motor is connected to terminal (7).
The start signal from the rotary system is wired between
DI1, DI3 and +24 at terminal (8).

Programming
Program all parameters as per the programming guide,
see page 3. Start from the top (and go down) accordingly.
During the programming, the fan must not receive any
start signal. This means that DI1, DI3 and +24 (8) cannot
be a closed circuit.
Note! The green parameters can be changed, to optimise
current system. The red parameters can be found on the
motor. The blue parameter ”LSP” indicates selected lowest
fequency (step 1), and parameter ”SP2” indicates selected
maximum frequency (step 2).

Default reset
When resetting to the factory settings, please proceed as
below:
If the display doesn’t show rdy, press ESC until it does.
Enter menu ConF and select parameter FCS-. Change the
value from FCS1 to Fry-, confirm with ENT. Change ALL,,
to ALL" by pressing ENT. Go back one step in the menu
with ESC and change from FrY- to 6FS. Press ENT and
change nO to yES by pressing and holding ENT for 5 s.
The frequency converter will now have the initial factory
settings and is ready for programming again.
The wiring is not done as per the
wiring diagram. Check the wiring.
DI1 and +24 are closed.
TROUBLESHOOTING GUIDE
Symptom Probable cause Recommended measure
1. Programming failure.
Remove wiring.
The parameters are not programmed
in the correct order.
Program the parameters, as per the
programming guide from the top to the bottom.
2. The system does not work.
Wrong rotation direction of the fan. Check rotation direction.
3. Performance loss
of the fan.
Troubleshooting
Troubleshooting when power is on, should
only be performed by an authorised electrician.
Information that makes it easier to identify occurred
problems that are easy to solve can be found in the
troubleshooting guide. Always go through trouble
shooting guide before contacting MOVEX.
