Safety instructions
•
Read the operating instructions in full before
starting up and follow the safety instructions.
• Keep the operating instructions in a place where
it can be accessed by everyone.
• Ensure that only trained staff work with the instrument.
•
Follow the safety instructions, guidelines, occupational health and safety and accident prevention regulations.
• Because the options for combining products,
tools, stirring vessel, experiment and medium
are nearly endless, user safety cannot be ensured simply with design requirements on the
part of the product. For this reason, it may
become necessary for users to take other precautionary safety measures. For example, glass
devices or other stirring vessels that are sensitive
to mechanical stress can be damaged or shattered by an imbalance, increasing the speed too
quickly or too little distance between the stirring
element and the stirring vessel. Users can suffer
serious injury from glass breakage or from the
freely rotating stirring element.
• Uncontrolled reactions can be triggered by mixing the heated material insuciently or by the
energy generated by selecting a speed that is
too high. In case of these and other increased
operational hazards, users must take additional
appropriate safety precautions (e.g. shatter protection). In any case, when using critical or hazardous materials in your processes, IKA® recommends to use additional appropriate measures
to ensure safety in the experiment. For example,
users can implement measures that inhibit fire
or explosions or comprehensive monitoring
equipment. Furthermore, users must make sure
that the OFF switch of the IKA® product can be
accessed immediately, directly and without risk
at any time, and above all, in case of fault.
DANGER
• Only process media that will not react dangerously to the extra energy produced through
processing. This also applies to any extra energy
produced in other ways, e.g. through light irradiation.
If installation or positioning
cannot ensure this access
at all times, an additional
EMERGENCY STOP switch
that can be easily accessed
must be installed in the work
area.
•
Do not operate the instrument in explosive atmospheres, with hazardous substances or under
water.
•
Process pathogenic materials only in closed ves-
sels under a suitable fume hood. Please contact
IKA® application support if you have any ques-
tion.
•
The instrument is not suitable for manual operation.
•
The high torque developed by the RW 47 digital
requires particular care in the choice of stand, cross
sleeve and anti-rotation element for the agitating
vessel.
• Set up the stand in a spacious area on an even,
stable, clean, non-slip, dry and fireproof surface.
• You must ensure that the stirring element is securely clamped in the chuck!
•
Use stirring shaft protective equipment and a
safety cutout for height adjustable stands!
• The agitated vessels used for stirring have to be
secured. Consider on a good stability of the entire structure.
DANGER
•
Protect the instrument and accessories from
bumping and impacting.
• Check the instrument and accessories before-
hand for damage each time when you use
them. Do not use damaged components.
•
Safe operation is only guaranteed with the acces-
sories described in the ”Accessories” section.
• Always switch the main switch in the OFF position or disconnect the power before changing
stirring element and fitting allowed accessories.
• The instrument can only be disconnected from
the mains supply by pulling out the mains plug
or the connector plug.
• The socket for the mains cord must be easily
accessible.
•
Socket must be earthed (protective ground
contact).
•
The voltage stated on the type plate must cor-
respond to the mains voltage.
• Please observe the permitted speed for the stirring element. Never set higher speed.
• Make certain that the unit is set at the lowest
speed before commissioning; otherwise, the
unit will begin running at the speed set in last
operation. Gradually increase the speed.
• Pay attention when setting the speed to any
imbalance of the stirrer tools and possible
spraying of the medium to be stirred.
Please pay attention to
the dangerous parts of the
equipment in Fig. 8.

DANGER
DANGER
DANGER
DANGER
DANGER
•
There may be electrostatic activity between the
medium and the output shaft which could cause
a direct danger.
• After an interruption in the power supply or a
mechanical interruption during a stirring process, the unit does not restart automatically.
• It is important to note that the surfaces of the
motor (cooling fins) and certain parts of the
bearing may get very hot during operation.
• Never cover the ventilation slots or cooling ns
on the motor as these are needed for cooling
the drive system.
• Avoid knocking and impacting on the lower end
of the shaft and the chuck gear teeth. Even minor, invisible damage can lead to imbalance and
uneven shaft action.
• Ensure that the stand does not start to move.
Never operate the instrument with the stirrer tools
rotating freely. Ensure that
parts of the body, hair, jewelry or items of clothing
cannot be trapped by the
rotating parts.
Wear your personal protective equipment in accordance with the hazard category of the medium to be
processed; otherwise there
is a risk of:
- splashing of liquids
- projectile parts
-
body parts, hair, clothing
and jewelry getting caught.
Beware of the risk of
- flammable materials
-
glass breakage as a result of
mechanical shaking power.
Reduce the speed if:
- the medium splashes out
of the vessel because the
speed is too high
- the instrument is not running smoothly
- the instrument begins to
move around because of
dynamic forces
- malfunction.
Do not touch rotating
parts during operation!
•
Imbalance of the output shaft, the chuck and
in particular the stirring tools can lead to uncontrolled resonant vibrational behavior of the
instrument and the whole assembly. Glass devices and stirrer containers can be damaged
or shattered by this. It can cause injury to the
operator, also can damage the rotating stirring
tool. In this case exchange the stirring tool for
one without imbalance or remedy the cause of
the imbalance.
it to the dealer or the manufacturer along with
a description of the fault.
• If the instrument is operated too long in overload or if the ambient temperature is too high,
the instrument switches off permanently.
• The machine must only be opened by trained
specialists, even during repair. The instrument
must be unplugged from the power supply before opening. Live parts inside the instrument
may still be live for some time after unplugging
from the power supply.
WARNING
WARNING
DANGER
• Before commissioning, the correct direction of
rotation of the motor must always be ensured
(test run without stirring tool: motor rotation as
indicated of the arrow on the front foil, clockwise rotation, looking down on motor). The
wrong direction of rotation can lead to the stirring tool coming off the shaft.
• If the unit is operated in different locations with
a 5-pin plug, the direction of rotation must be
checked before each commissioning, with no
stirring tool fitted.
If there is still imbalance, return

Useful information
You can set speed from 57 to 1300 rpm with the
50 Hz (mains frequency) and speed from 69 to
1560 rpm with the 60 Hz (mains frequency). The
unit may heats up during use. The ample cooling
surfaces on the motor serve to distribute and radiate the heat as evenly as possible.
You can also use large mixing vessels together
IKA® stands without any problem.
with
Drive
The motor can be infinitely adjusted via a friction
wheel drive unit but is operated in one position
only. The power output, rotational speed and
torque of the motor are regarded as constant and
are optimized for this operating position. After
the friction wheel drive the motor power output
is transmitted to the output shaft of the stirrer via
either the first or second stage of the subsequent
manually adjustable toothed gear train.
The unit comes without a connection cable because the user’s installation means that it is not
possible to issue a standard length cable due to
the different sizes of premises. Experts can determine the pin assignment from the wiring plan.
The output shaft is not designed as a hollow shaft
and allows inserting the stirring element until it
stops. It is important to ensure that the stirrer
shank is securely clamped in the chuck.
Neglecting all losses, the power at the output shaft
during power transmission (conversion) is always as
great as the power output of the motor. The gear
train merely provides rpm and torque conversion,
which can be described in purely theoretical terms
by the characteristic curve plotted in Fig. 2.
Friction wheel wear is kept low by a helical clutch
matched to the gear train. The down-pressure required at the friction wheel is adjusted by the helical
clutch according to the moment acting on the stirrer
shaft. A low torque results in a low down-pressure;
a high torque results in a high down pressure.

Motor circuit breaker
The ball race three-phase motor is maintenancefree. Its attached switching unit features a special
safety device for operation in the case of overcurrent and under-voltage (under-voltage release)
to permanently disconnect the motor and avoid
thermal damage. The instrument can only be
started up again by activating the ON switch (A,
see Fig. 1), when power permitted for the motor
is supplied.
You can nd the basic connection and rating for
the motor on its rating plate.
Gear speed change
You can select one between two gear positions (I
and II) using the toggle button (E, see Fig. 1) on
the front of the instrument. You can only switch
to a different cog wheel gear level when the instrument is switched off (motor stopped).
Output shaft
The safety switch SI 400 can also be connected
to the motor switching unit. When used in combination with an
switch on the instrument only at a defined height
in the stand’s working range.
If the stirring unit is operated in such a way that
the instrument’s OFF switch (B, see Fig. 1) is not
accessible, you must add another EMERGENCY STOP switch to the work area so that it can be
easily reached.
Otherwise this may cause damage to the gear
cogs. The arrow on the front foil indicates the direction of the chuck.

During commissioning of the machine the output
shaft starts to run at the speed setting in last operation. Therefore check the setting of the control
knob (speed). Also ensure that the speed set is
suitable for the test medium selected. If you are unsure, set the motor slide to the lowest speed (front
motor slide stop) using the rotary control knob (C)
on the side and the gear to the lowest level.
Maintenance and cleaning
The instrument will start up when you press the
ON switch (A) on the motor.
If the unit has not been used for some time, a
knocking noise will be heard when switching on,
which is due to the preload on the friction lining
of the friction wheel drive. This has no detrimental
effect on the function of the unit, and the knocking
noise will disappear after a short running-in period.
The equipment is maintenance-free. It is only
subject to the natural wear and tear of components and their statistical failure rate.
