Mounting instructions
These speed controllers use miniature mo-
tor capacitors that are switched in series or
parallel in four positions to vary the voltage
supplied to the motor. Ideal application: hum-
free control of fans and ceiling fans. Selections
are done by the 6 positions switch (0-4-3-2-1-
0 position). The “0” position stops the fan.
Technical data:
Power supply: 230 Vac - 50/60 Hz
Current range Fuse
ST4-150 II: 1,0 A F 1,25 A - H
Max. load: 150 W
Enclosure external: plastic, ASA, RAL 9010 white-
ivory
Enclosure internal: polyamide According to IEC
60335
Max ambient temperature: 35 °C
All works may only be carried out by skilled
personnel following the local regulations
and
AFTER the controller is completely separated
from the mains.
Inset mounting (IP 44)
Break mains voltage. Connect according to
diagram. Mount innercase to the wall with con-
nections pointing down. Mount cover with nut
to the wall. Push knob in place at off position.
Surface mounting (IP 54)
Break mains voltage. Mount surface moun-
ting case to the wall together with included
grommets. Connect according to diagram.
Mount inner case in surface mounting case
with included screws. Mount cover with nut
to surface mounting case. Push knob in place
at off position. When needed a 5 mm hole for
condensatation water is to be drilled at the
bottom of the surface mounting case.
Connections (fig.)
1. Mains connection : 230 V - 50/60 Hz
2. Fuse-box with spare fuse. (Fast, ceramic)
3. Switched output to motor
The controller is only to be used together with
fans that are suitable for speed control by
capacitors. The motor used should be internally
protected against over heating.
In case of faulty operation, please check that:
right voltage is applied. All connections
are correct. The machine to be regulated is
functioning. The fuse in fusebox is OK. The
fuse in the controller is OK.
Change of fuse
Undo knob by first turning the knob to the
right beyond end stop and then pull. Remove
the nut. Remove fuse holder with a screw-
driver. Change fuse. Put the details back in
place. Use only recommended fuses (Appro-
ved, fast, with high breaking
capacity ) otherwise loss of warranty will
ensue.
Warranty
One year from delivery date against defects
in manufacturing. Any modifications or alte-
rations to the product relieve the manufac-
turer of all responsibility.
Maintenance
In normal conditions the controllers are
maintenance-free. If soiled clean with dry
or dampish cloth. In case of heavy polluti-
on clean with a non-aggressive product. In
these circumstances
the controller should be disconnected from
the mains. Pay attention that no fluids enter
the controller. Only reconnect the controller
to the mains when it is completely dry.
Replace fuse only with same type and rating.
