› Read the operating instructions in its entirety before using the device 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 device�
› Follow the safety instructions, guidelines, occupational health and safety and accident

prevention regulations�

!

Notice!

› Pay attention to the marked sites in Fig. 1�

/// Device design

Caution!

› Device surface is partially made of glass:

- Glass surface can be damaged by impact�

- If glass surface is damaged it could cause injury, don`t use the device anymore�

!

Notice!

› Set up the device in a spacious area on an even, stable, clean, non-slip, dry and fireproof

surface�
› The feet of the device must be clean and undamaged�
› Keep the base plate clean�
› Protect the device and accessories from bumps and impacts�
› Check the device and accessories for damage before each use� Do not use damaged

components�

/// Working with the device

Danger!

› With substances capable of forming an explosive mixture, appropriate safety measures must

be applied, e�g� working under a fume hood�
› To avoid body injury and property damage, observe the relevant safety and accident

prevention measures when processing hazardous materials�

Warning!

› 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�
› Beware of hazards due to:

- glass breakage,

- incorrect container size,

- overfilling of media,

- unsafe condition of container�

› Process pathogenic materials only in closed vessels under a suitable fume hood�

6 7

Caution!

2

1

› Wear your personal protective equipment in accordance with the hazard category of the

media to be processed� There may be a risk from:

- splashing and evaporation of liquids,

- ejection of parts,

- release of toxic or combustible gases�

› Reduce speed if:

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

- device is not running smoothly,

- container moves on the base plate�

› Please consider any possible contaminations and unwanted chemical reactions�
› 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 system at temperatures
above 300 °C – 400 °C� Only elementary fluorine, chlorotrifluoride and alkali metals attack

it; halogenated hydrocarbons have a reversible swelling effect�
(Source: Römpps Chemie-Lexikon and ”Ulmann”, Volume 19)
› The device has a vessel detection function� If this is switched on and a vessel is placed on the

footprint, the motor function is activated� Liquid or other objects on the footprint, can also

activate the motor function at this moment�

Warning / Errors

1. Motor overload

Red
circle

1. 1.

Or

Red

If the allowed motor power is overloaded by the user
application, the device automatically reduces the
speed value step by step until the motor can reach a
stable operating state�
The warning is indicated by slow or fast flashing of
the display:

- Fast flashing: Immediate reduction of the speed�

- Slow flashing: Slow reduction of the speed

The automatic reduction of the speed is indicated by
the blue setpoint LED lighting up in red�
The user has to confirm one-time the button “-” or “+”
to reset that state�

Blue

When working in Leader / Follower mode, this state
can only be deleted at the Follower units by a restart
(power interruption)�
See also the following explanation:

Behaviour in case

of motor overload of a follower or leader unit

3.Permitted minimum input voltage is too low

Display shows the following warning indication�
Solutions:

- Change the position of the device�

Red

2 digits off

- Reduce the number of the units�

- Change the position of the power plug�

Extended behaviour in Leader / Follower mode with regarding to the permissible
minimum input voltage:

If the Leader unit detects a too low input voltage, it will lead to a reduction of the stirring speed,
same as explained at warning 1� The Leader will reduce the speed until a stable operating state
was established�

4. Maximum input current allowed overshot

Display shows the following warning indication�
Solutions:

- Limit the stirring load

Red

- Reduce the number of the units�

Behaviour in case of motor overload of a follower unit:

3 digits off

If the motor power of a follower unit is overloaded, the unit may deviate from the specified
speed of the leader unit� The priority is therefore the limitation of the maximum motor power�

Behaviour in case of motor overload of a Leader unit:

If the motor power of a leader unit is overloaded, but does not apply to the follower units, they
still follow the reduced preset speed of the leader unit� Priority is therefore given to the leader
unit and its maximum permissible speed specification�

Extended behaviour in Leader / Follower mode with regarding to the permissible
maximum input power:

If the Leader unit detects a too high input power, it will lead to a reduction of the stirring speed,
same as explained at warning 1� The Leader will reduce the speed until a stable operating state

2. Maximum internal device temperature exceeded

Inner housing Temperature > 70°C:
Display shows the warning by slow flashing�
Device operation continues�

Red

Inner housing Temperature > 75°C:
Display shows the warning by fast flashing�

1 digit off

Device operation continues�

was established�

5. Motor error

Display shows the following error indication�
Solutions:

- Contact the Service department�

Red

Inner housing Temperature > 80°C:
Display shows the error steady (no blinking) and the buzzer
beeps�
