2 Equipment description
Figures 1 to 4 show the components together with their position numbers.
Every magnetic stirring system MINI, MICRO, COMPACT and MAXI is equipped with
one stirring point (1). The drive is inside the housing of the stirring drive (2), which is
completely watertight. This prevents germs from penetrating into the inside of the
stirring drive (2). The stirring drive (2) is cleared for use in safety laboratories and sterile
rooms. The drive is constructed without the use of moving parts and therefore totally
wear-free.
The stirring drive (2) gets its power either from the TELEMODUL control unit
(3; Figure 2) or the TELEMODUL 20 C / 40 C control unit (5; Figure 3).
On the budget-priced equipment incorporating the TELEMODUL control unit (3), the
rotation speed can be preselected continuously. This is done using the rotation speed
control button (6). The TELEMODUL control unit (3) can be of the plug-in type, or be
fitted with a mains cable.
The TELEMODUL 20 C / 40 C (5) is available in two models, 20 C and 40 C. These two
models differ with regard to maximum speed and to stirring power (for details see the
technical specifications). The TELEMODUL 40 C control unit is additionally equipped
with a RS 232C port. The RS 232C interface can be used to remote-control the control
unit from a PC.
The TELEMODUL 20 C / 40 C (5) interface is menu-driven. The display (10) shows the
selected speed (rpm) and gives an overview over the functions selected.
You may preset speed and stirring power as well as change the stirring mode. The
adjusting wheel (8) is used for selecting the appropriate menu and for adjusting the
desired value. The three program keys (9) can be individually defined.
After the startup time (soft start) the stirring bar turns or mixes at the selected speed.
The TELEMODUL 20 C / 40 C (5) can be equipped with a four-way or eight-way
benchtop distributor (accessory), allowing you to control 2, 4, 6 or 8 stirring drives
simultaneously.
Stirring vessels and magnetic stirring bars do not fall within the scope of delivery.
