The induction heating devices HEATER50-SMART, HEATER100-
SMART, HEATER150-SMART and HEATER200-SMART give rapid,
clean operation. Their high eciency level allows energy-
ecient heating and shorter mounting times. This reduces
the operating costs. The uniform, controlled heating allows
consistently good quality of mounting.
Operation is simple and user-friendly, the touch-sensitive
screen is oil-resistant, dustproof and waterproof.
When heating by induction is used, there is no need at
all to use oil – this gives particularly good environmental
compatibility. The scope of application is very extensive.
It is possible to heat the loose inner rings of cylindrical or
needle roller bearings as well as sealed and greased bearings.
Compared with previous models, further improvements have
been made in performance capacity and safety and the part to
be heated need no longer be of a minimum mass.
In order to ensure durability in demanding industrial
operation, the devices are extremely robust and reliable.

2. Safety, warnings and potential hazards
2.1 Explanation of the
pictograms

8Schaeer Technologies
Warning! Voltage
Be aware that you are working with an
electrical appliance. On the mains side as
well as internally, voltages occur that can lead
to serious injury and death if used inexpertly
or improperly.
■Connect the unit to the power according to
the information on the rating plate.
■Before each use, check the power supply
cable for damage.
■Safe disconnection from the power supply
must be ensured at all times before
starting maintenance and repair work. This
can be achieved by removing the power
plug from the socket.
Warning! Electromagnetic field
Be aware that you are working with an
appliance that generates electromagnetic
fields. Keep a distance of 1 metre from the
unit when switching on.
These fields can be harmful for persons with
active medical aids such as heart pacemakers.
These fields can be harmful for persons
with passive medical aids such as joint
prostheses. The wearing of jewellery can also
result in injuries due to burns.
It is forbidden for persons with active medical
aids to be in the immediate vicinity of the
unit when it is in operation. The generated
electromagnetic field may influence the
proper function of such medical aids.
It is forbidden to wear jewellery when working
with the generator and inductors. There is
a risk of the jewellery being heated by the
electromagnetic field and resulting in injuries
due to burns.
For this reason, persons with passive
implants are recommended not to enter the
immediate vicinity of the induction heater
when it is in operation.
2.2 Description of
potential hazards

Schaeer Technologies 9
Furthermore, it cannot be ruled out that the
electromagnetic fields could cause damage to
electronic and magnetic data media. Keep such
equipment away from the induction heater.
Caution! Tripping hazard
Limit the risk of injury due to tripping as
far as possible.
■Keep your place of work tidy. Remove any
loose and superfluous objects from the
immediate vicinity of the unit.
■Position any (power supply) cables as
low as possible to minimise the risk
of tripping.
Caution! Risk of burns
The workpiece becomes warm to very hot
during heating.
Parts of the unit may also become hot due
to contact with the workpiece or the heat
radiated by the workpiece.
Therefore always wear heat-resistant gloves
when handling workpieces in order to avoid
injury due to burns.
Caution! Risk of injury during lifting
A number of units in the Schaeer heater
range weigh more than 23 kg and may
therefore not be lifted by one person alone.
(see technical specs)
If a unit weighs more than 23 kg, lift it with
two persons or use suitable
lifting equipment.
Wear safety shoes to prevent injury from
unintentionally falling workpieces and/or
machine parts.

10 Schaeer Technologies
■The user must carefully read this manual and be familiar
with the safety standards in the work practice.
■Follow the instructions in the manual at all times.
■Check the connection voltage against the rating plate on
the unit. If the power cord does not have one, make sure it
is fitted with the proper plug. This must be fitted by a
qualified electrician.
■Never use or store an induction heater in a
damp environment.
■Only use Schaeer induction heaters indoors.
■If using a mobile version; always lock the castors when
not moving the device.
■If the heater is equipped with extendable horizontal supports,
always secure them with the appropriate locking pin. both in
the fully retracted and in the fully extended position.
■Use suitable lifting equipment according to the weight of
the ledge or component.
■Never use a metal strap to support workpieces or suspend
them in the magnetic field. High currents could start
running through the strap, causing it to heat up.
■Do not hold metal objects near and poles.
■Whilst heating, observe a minimum distance of 1 metre
from the heater.
■Never remove the induction ledge during heating.
■Do not modify the heater. Never use home-made ledges.
■Always check that the induction ledge is positioned
correctly against the poles, so excessive vibration cannot
cause personal injury or damage to the device.
■Do not switch on the heater until the core is closed
with a ledge.
Hazard area
The hazard area of the heating device can represent a danger
of death.
DANGER!
Danger of heart stoppage in persons fitted with
a pacemaker due to the strong electromagnetic
field. Ensure that persons fitted with a
pacemaker remain outside the hazard area of
the heating device. Erect barriers and attach
clearly visible warning signs, Figure 1.
2.3 Safety measures
to be taken

Schaeer Technologies 11
■The electronic systems switch o automatically if the
ambient temperature rises above 70ºC.
■When heating in temperature mode, the heater switches o
if no 1°C temperature increase is measured during a time
pre-set by the manufacturer.
■The coil of the heater is equipped with a temperature
monitor. If the coil becomes too hot, the heating process is
switched o entirely.
■Models with a swivel arm are equipped with a safety
positioning cam.

The operation of the heater is based
on inducing a (low frequency) current
in the bearing. This is achieved
by incorporating the bearing as a
secondary winding in a transformer.
The primary winding is connected to
the mains by means of an electronic
controller. The magnetic field induces
a high current (short-circuit current)
through the bearing, which then becomes hot. After each
heating cycle, the bearing or workpiece is demagnetized.
Schaeer induction heaters are intended for heating
bearings, so they can be assembled easily by means of a
shrink fit. Subject to professional assessment, they can also
be used to heat bushings, cogwheels, couplings and metal
objects that form a closed circuit. Bearings and workpieces are
demagnetized automatically after each heating cycle.
Bearings and workpieces can be heated to a maximum
temperature of 240ºC (464°F).
Schaeer induction heaters are suitable for continuous use.
However, when heating to a temperature of 240°C (464°F), do
not so for more than half an hour.
CAREFUL!
■Bearings may be heated to a maximum of 120°C (248°F).
■Precision bearings may be heated to a maximum
of 70°C (158°F). Higher temperatures can aect
metallurgical structure and lubrication, resulting in
instability and failure.
■Do not use a heater for bearings and workpieces that
are outside the minimum and maximum dimensions
specified in the technical specifications.
■Never switch o the unit with the main switch while it
is still heating up.
3.1 Application
3.2 Operating conditions ■Only use the device indoors.
■Fit for use in an industrial environment, at an ambient
temperature of 0ºC (32°F) to 50ºC (120°F) and humidity of
5 to 90% – non-condensing.
At temperatures below 0°C (32°F), the unit stops operating.
3.3 Principle of operation
