Safety instructions

For your protection

• Read the operating instructions in full before starting

up and follow the safety instructions.

• Keep the operating instructions in a place where they can be
accessed by everyone.

• Ensure that only trained staff work with the appliance.

• Follow the safety instructions, guidlines, occupational health
and safety and and accident prevention regulations.

• Socket must be earthed (protective ground contact).
Attention - Magnetism!

ATTENTION

Effects of the magneticfield have to be
into account (e.g. data storage media,
cardiac pacemakers ...).
RT

DANGER

Risk of burns!
Exercise caution when touching the

housing parts and the heating plate.
The heating plate can reach temperatures in excess of 125 °C.
Pay attention to the residual heat after switching off.
RT

WARNING

Ensure that the mains power supply
cable does not touch the heating base
plate.

• Wear your personal protective equipment in accordance with
the hazard category of the media to be processed. Otherwise
there is a risk from:

- splashing and evaporati on of liquids

- ejection of parts

- release of toxic or combustable gases.

• Set up the appliance in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.

• The feet of the appliance must be clean and undamaged.

• Check the appliance and accessories beforehand for damage
each time you use them. Do not use damaged components.

• Gradually increase the speed.

• Reduce the speed if

- the medium splashes out of the vessel because the speed is
too high

- the appliance is not running smoothly

- the container moves on the base plate.

RT

WARNING

Caution! Only process and heat up any
media that has a flash point higher than
180 °C.
The safe temperatue limit must always be set to at least 25 °C
lower than the fire point of the media used.
Beware of hazards due to:

WARNING

- flammable materials

- combustibles media with a low boiling temperature

- glass breakage

- inkorrect container size

- overfilling of media

- unsafe condition of container.

• The appliance may heat up when in use.

• The base plate can heat up due to the action of the drive mag­ nets at high motor speeds, even if the heater is not operational.

• Process pathogenic materials only in closed vessels under a
suitable extractor hood. Please contact IKA
questions.
Do not operate the appliance in explo-

DANGER

sive atmospheres, with hazardous
substances or under water.
Only process media that will not react

DANGER

dangerously to the extra energy produ­ ced through processing. This also ap­ plies to any extra energy produced in other ways, e.g. through
light irridiation.

• Please observe the operating instructions for any accessories
used.

• Safe operation is only guaranteed with the accessories descri­ bed in the „Accessories“ chapter.

• Accessories must be securely attached to the device and cannot
com off by themselves. The centre of gravity of the assembly
must lie within the surface on which it is set up.

• Always disconnect the plug before fitting accessories.

• The appliance 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.

• It may be possible for wear debris from rotating accessory parts
to reach the material being processed.

• When using PTFE-coated magnetic bars, the following has to
be noted:
Chemical reactions of PTFE occur in contact with molten or

solute alkali metals and alkaline earth metals, as well as with
fine powders of metals in groups 2 and 3 of the periodic sys­ tem at temperatures above 300 °C - 400 °C. Only elementary
fluorine, chlorotrifluoride and alkalimetals attack it; halogena­ ted hydrocarbons have a reversible swelling effect.

For protection of the equipment

• The appliance may only be opened by experts.

• The voltage stated on the type plate must correspond to the
mains voltage.

• Do not cover the device, even partially e.g. with metallic plates
or film. This results in overheating.

• Protect the appliance and accessories from bumps and impacts.

• Ensure that the base plate is kept clean.

• Observe the minimum distances between the devices, between
device and wall and minimum distances (min. 800 mm) above
the assembly, see Fig. 2.

Commissioning

RO/RT

Observe the ambient conditions (temperature, humidity, etc.)
listed under Technical Data.

The device is switched on and off via the switch (A) located on
the right-hand side of the device. On the front panel a small
arrow labelled Power above the display (B) indicates the location
of the switch.

The safety of the user cannot be guaranteed if the appliance is
operated with accessories that are not supplied or recommended
by the manufacturer or if the appliance is opreated improperly
contrary to the manufacturer‘s specifications or if the appliance or
the printed circuit board are modified parties.

After the device is switched on a display self-test is performed.
The display cycles through the following information:

• All segments light up

• The software version and the selected mode are displayed

• The selected “Eco Mode” is displayed
(E when ECO mode is active)

• If the drive has not been started the display reads „OFF“. If
the drive has been started the selected speed is displayed.

Safe temperature limit

RT

The max. attainable heating plate temperature is restricted to 130
°C by a permanently set safety temperature limit. Once this limit
has been attained, the device switches off the heating.

Setting the safe temperature limit

RT

The safety temperature is set as follows:
Switch the device on using the On/Off switch
on the right side of the device.
As soon as the display shows SAFE, press and
hold down the Temp membrane key and use

Stirring function

The stirring function is started and stopped by pressing the „Start/
Stop“ button (C).
Pressing the +/- buttons (E or D) increases or reduces the speed.

the +/- membrane keys (H or I) to set the
desired safety temperature.

The set safety temperature is displayed.

Once the Temp membrane key is released, the safety temperature
is saved.

ECO mode

RO/RT

The heat generated in the device can be reduced by lowering the
power of the input coils.
Pressing the “ECO Mode“ (F) key to reduce the current power
setting. ECO mode is indicated by an “E” preceding the speed.
When the power is set to ECO mode, the speed is limited to 600
rpm.

Operating modes

RO/RT

To toggle between modes, press the Start/Stop key (C) when
switching on.

Operating Mode “A”
All the parameter settings are retained when the device is
switched off or disconnected from the mains.
The “Start/Stop” (C) key starts the device with the set parameters.

Operating Mode “B“
All parameter settings, including “Start/Stop”, are saved when the
device is switched off.

Direction of rotation reversal

To make the stirring power more independent from the speed
range, press the “ECO Mode“ membrane key (F) and then select
one of the following setting options.

P50 (Stirring power 50% independent of the speed range)
P75 (Stirring power 75% independent of the speed range)
P100 (Stirring power 100% independent of the speed range)

---- (Standard stirring performance with the stirring power
regulated by the speed)

Operating Mode “D“
In the D mode the device operates as per the A mode but with the
following exception:

- Switch on and then press the “Temp” membrane key to confirm
the safety temperature.

- The value flashes until it is confirmed.

Factory setting: mode A

RO/RT

The (G) key activates the “Reverse Rotation” function.
When the „Reverse Rotation“ function is switched on, a decimal
point (K) appears in the LCD display.

The running time (30, 60, 90 or 120sec) is set by pressing the (G)
key followed by the +/- keys.

After the preset running time, the drive is switched off and
restarted at minimum speed in the opposite direction after a
pause specific to the speed.

Function Heating

RT

The heating function is started and stopped by pressing the
„Temp“ button (J).

Maintenance and cleaning

The equipment is maintenance-free. It is only subject to the natu­ral wear and tear of components and their statistical failure rate.

Cleaning

For cleaning disconnect the main plug..

Use only cleansing agents which have been approved by IKA
clean devices.

®

to

In this way the magnetic rod is captured and any liquid still
rotating is gradually slowed down. Then the drive accelerates to
the target speed.

Note: If the “Reverse Rotation” key (G) is pressed again, the drive
will keep rotating in the same direction.

When the device is started up again, the drive will rotate in the
direction last set.

Pressing the +/- buttons (H or I) increases or reduces the
temperature.
