FASEC 33
SINGLE-PHASE SPEED CONTROLLER
GENERAL DESCRIPTION
FASEC 33 is an instrument designed to con-
trol speed and is particularly suitable for
fan applications.
Its standard version provides a triac output
to drive a load up to 2.5 A, while a special
version allows regulation of loads 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 power voltage.
Another special model is available for
speed regulation in ZHIEL motors.
OPERATION
The operation logic of FASEC 33 is based on
the concept that as temperature increases
an increase in the number of turns of the
applied load (condensation) follows.
The regulation Set is set through the central
potentiometer "0% speed" (scale 0...60 °C).
The temperature differential, which deter-
mines the temperature at which the load
turns at the maximum speed when summed
to the Set value, is set through the "100%
speed" potentiometer (scale 3...31 °C).
The "min speed" potentiometer allows to
set a minimum speed below which the
motor will never operate.
• regulador de velocidad monofásico
• régulateur de vitesse monophasé
It is used in case of high inertia loads that
FASEC 33 cannot control when the output
controlling voltage is very low. Example of
application: let's assume the starting tem-
perature is set to 30 °C (0% speed) with a
differential of 10 °C (100% speed).
When the temperature reaches 30 °C the
fans begin to turn at a speed which is slight-
ly higher than the minimum set; when the
temperature reaches 40 °C (30+10) the fans
operate at maximum speed.
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 external filter (for the version with 7 A
capacity) is provided with a bolt for fixing.
ELECTRICAL CONNECTIONS
Work on electrical connections always with
the machine turned off. The instrument is
provided with wiring for the connection to
an Octal socket.
The PTC-type probe does not need to
observe any polarity, and it can be length-
ened by using a normal bipolar cable (we
remind you that an increased length affects
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.
ALLOWED USE
For your safety, FASEC 33 should be
installed and used according to the given
instructions and, especially, no components
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 protected
from water and dust considering its appli-
cation. Its rear side should only be accessi-
ble by using a tool.
FASEC 33 is suitable to be incorporated in
household appliances and/or the like, and
it has been tested -as regards its safety- to
the reference European
Standards.
It is rated:
• according to is construction, as an auto-
matic, electronic control device to be
incorporated.
• according to its automatic operation fea-
tures, as a 1Y-type acting control device.
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 evi-
dent safety reasons, must be carried out
outside the instrument.
LIABILITY AND RESIDUAL RISKS
Eliwell Controls s.r.l. is not liable for any
damages caused by:
- installing or using this instrument in a dif-
ferent way than it was designed for, and in
particular, without complying with the safe-
ty prescriptions provided for by regulations
and/or hereby stated;
- using it on equipment which does not
ensure an adequate protection from elec-
trical shock, water or dust considering the
way it has been installed;
- using it on equipment which allows
accessing dangerous components without
using any tools;
- tampering with the product or altering it;
- using it on equipment which does not
comply with legal provisions and regula-
tions in force.
