FASEC 43/43C
automatic speed controller
WHAT IT IS
GENERAL DESCRIPTION
FASEC 43/43C is designed for speed con-
trol and is particularly suitable for fan appli-
cations.
The standard version provides a triac out-
put to control a load up to 2.5 A, while a
special version ensures control up to 7 A.
The latter version contemplates the use of
an LC filter fitted outside the instrument.
Such filter is necessary to reduce conduct-
ed emissions and radio frequency due to
the type of regulation.
The temperature probe is galvanically insu-
lated from the supply voltage.
Another special model is available to con-
trol speed in ZHIEL motors.
0 °C starting temperature (0% speed) and
a 10 °C differential (100 % speed): when
the temperature reaches 0°C both fans
start spinning at a speed which is slightly
over the minimum set speed; when the
temperature reaches 10 °C (0-10) the fans
operate at maximum speed.
FASEC 43/43C is designed for
speed control and is particularly
suitable for fan applications.
MECHANICAL MOUNT
The instrument is designed for panel
mount. Drill a 45x92 mm hole and insert
the instrument holding it with the special
brackets supplied.
The operating temperature range allowed
for correct operation is from –5 to 65 °C.
Do not install the instrument in moist
and/or dirty places or near heat sources.
The filter (for the version with 7 A capacity)
is provided with a bolt for fixing.
HOW IT IS MADE
• Size: front panel 48x96 mm, depth
96 mm (excluding socket)
• Mounting: panel mount on hole
45x92 mm
• Connections: Octal socket
• Input: PTC probe
• Regulation output: 2.5 A TRIAC,
7 A TRIAC
• Filter external (in version 7 A):
maximum current for load supply
7 A; cylinder size ø 38 mm, height
28 mm; fixing bolt M8
• Regulation type: phase choking
proportional
• Function type: evaporation
• Power supply: 230 V
OPERATION
The logical operation of FASEC 43/43C is
based on decreasing the turns of the load
(evaporation) as the temperature increas-
es. The regulation Set can be adjusted
through the central “0% speed” poten-
tiometer (scale –40…30 °C/0…60 °C).
The temperature differential , which sub-
tracted from the Set determines the tem-
perature for the load maximum speed, can
be set through the “100% speed” poten-
tiometer (scale 3…31 °C).
The “min speed” potentiometer allows to
set a minimum speed below which the
motor won’t work. It is used in case of high
inertia loads which cannot be controlled by
FASEC when the output control voltage is
very low.
Example of operation: suppose to set a
A
50 Hz.
ELECTRICAL CONNECTIONS
Work on electrical connections always with
the machine turned off. The instrument is
provided with a connection for Octal sock-
et wiring.
The PTC-type probe does not need to ob-
serve any polarity, and it can be length-
ened by using a normal bipolar cable (we
remind you that an increased length af-
fects the behaviour of the instrument from
the electromagnetic compatibility point of
view: wiring should be carried out with
great care). It is advisable to keep the
probe wire away from other power cables.
CONNECTIONS FASEC 33/43 7 A
FORBIDDEN USE
Any use different from the allowed one is,
as a matter of fact, forbidden.
We remind you that the effected regulation
has a functional value, and it is subject to
failure: any protective device provided for
by the regulations concerning this product
or suggested by common sense due to
evident safety reasons, must be carried
out outside the instrument.

ALLOWED USE
For your safety, FASEC 43/43C should be
installed and used according to the given
instructions and, especially, no compo-
nents subject to dangerous voltage must
be accessible under normal conditions: the
only accessible part must be the front of
the instrument.
This device should be adequately protect-
ed from water and dust considering its ap-
plication. Its rear side should only be
accessible by using a tool.
