/// 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�

Caution!
› 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�

› Once a “Leader“ device has been configured in the stirring system, the “Follower“ devices are control-
led synchronously. All keys including the vessel detection of the “Follower“ devices are deactivated.
› This allows stirring operation of the “follower“ devices across the permissible footprint, e.g. in the form
of a larger container (as shown below) covering the working surface of the “follower“ devices.

4. Maximum input current allowed overshot
5. Motor error
Display shows the following warning indication�
Solutions:
- Limit the stirring load
- Reduce the number of the units�
Display shows the following error indication�
Solutions:
- Contact the Service department�
3.Permitted minimum input voltage is too low
Display shows the following warning indication�
Solutions:
- Change the position of the device�
- 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�
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
was established�
Warning / Errors
1. Motor overload
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�
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
Behaviour in case of motor overload of a follower unit:
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�
2. Maximum internal device temperature exceeded
Inner housing Temperature > 70°C:
Display shows the warning by slow flashing�
Device operation continues�
Inner housing Temperature > 75°C:
Display shows the warning by fast flashing�
Device operation continues�
Inner housing Temperature > 80°C:
Display shows the error steady (no blinking) and the buzzer
beeps�
Device operation interrupted� The Motor stops�
Allow the device to cool down�
