› Imbalance of the output shaft, the chuck and in particular the stirring

tools can lead to uncontrolled resonant vibrational behavior of the device

and the whole assembly. Glass apparatus 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. If there

is still imbalance, return it to the dealer or the manufacturer along with a

description of the fault.

› There may be electrostatic activity between the medium and the output

shaft which could cause a direct danger.

› Never operate the device 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.

› Pay attention when setting the speed to any imbalance of the stirrer tools

and possible spraying of the medium to be stirred.

› Ensure that the stand does not start to move.
› 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.

Reduce the speed if:

› the medium splashes out of the vessel because the speed is too high,
› the device is not running smoothly,
› the device begins to move around because of dynamic forces,
› an error occurs.

The stirring device is suitable for continuous operation. The motor current is
limited electronically. The device has an anti-stall and anti-overload system.
If a fault occurs, a safety circuit immediately switches off the motor
permanently. The device starts with the last settings made. If the device
vibrates too much, an error message appears on the display and an acoustic
signal sound (see chapter “Error codes”).

Speed

/// Speed – normal operation

Speed - regulated (no variation in speed):
The speed is monitored and regulated by processor controlled. The target
speed is constantly compared with the actual rotation speed value of the
output shaft and variations corrected. This guarantees a constant speed even
if the viscosity of the substance being stirred changes.
Fluctuations in mains voltage within the permitted tolerance range have no
effect on the quality of regulation and constancy of speed.
The speed is set using the front knob. During normal operations
the speed value on the display corresponds to the speed of the
output shaft in revolutions per minute (rpm).

/// Speed – overload operation

When solid or semi-viscous substances are added, the stirrer can be run for
a brief period at 130% its rated power. When running in the overload range
(for instance if the viscosity has increased at a particular stage of the process)
the speed will reduce to a degree sucient to keep the torque on the stirrer
shaft within the rated torque of the device.

Useful information | Speed 1918 Unpacking

Overload status 1

The device is already running within the overload range, however, the actual
speed does not match the set speed. This condition is maintained as long as
neither the motor current nor the device temperature exceeds their permissible
limit value. In this overload status the torque value flashes.

Overload status 2

The device stop at a load above 130 % of the nominal torque.
Message in the display (see “Error codes” section).

/// Output shaft

Caution! ( )

Please see section “Safety instructions“!

The clamping chuck and output shaft permit clamping IKA recommend stirrer
tools (see section “Permitted IKA Stirrer tools“). The output shaft is designed
as a hollow shaft and the opening on the top side of the housing is closed
with a plastic cover. When the stirrer cover is opened, it is possible for stirring
shaft to be pushed out over the top edge of the housing at standstill, e.g.
during changing container.
For safety reason, the stirrer cover must be pushed back into the opening of
the housing so that it is properly closed. This is the only way to ensure that
working with the unit is safe and that media cannot enter the device.
