10.1 Device description and functional description
The inductive stirring system is designed for the stirring of liquids in special BOD bottles. It comprises
a super-flate stirrer drive with 6 stirring positions and the mains adapter. The inductive stirrer drive
does not have a motor and is thus wear-free. It is especially well-suited for stirring during continuous
operation in thermocabinets. It is completely protected from dripping water due to its hermetically
sealed encapsulation. It can be used in harsh environmental conditions.
The wide recess between the stirring positions also ensures greater ventilation of the containers in
the thermocabinet. The stirrer drive is supplied with power via the mains adapter and has integrated
control electronics. When switched on, a soft-start at reduced speed assures an even start-up and
centring of the magnetic stir bars.
The electronically controlled automatic monitoring unit reduces the speed about every 40 seconds. In
the process, each magnetic stir bar is re-centred in the bottle for a few seconds. Therefore, you can
easily exchange individual bottles while the unit is switched on.
Due to the synchronous operation, mutual interference of the magnetic stir bars can be practically
ruled out altogether.
10.2 Commissioning
WARNING!
Observe the SAFETY INSTRUCTIONS at the beginning of the manual.
DANGER! Electric shock.
Only use the mains adapter with dry hands! Only use the mains adapter in dry rooms! Do not use the
mains adapter if it is damaged! Only use the mains adapter in undamaged sockets which are suitable
for this purpose! Only use the mains adapter with a primary voltage and frequency which match the
technical specifications of the mains adapter!
DANGER! Magnetism
The magnetic fields can influence parts which are sensitive to magnetic fields, magnetic parts, or
metal parts (e.g. data carrying media, pacemakers, watches, magnetic strips, etc.). Keep these parts
away from the stirrer drive and magnetic stir bars.
ATTENTION!
The device may not be operated in explosion-prone rooms.
ATTENTION!
Observe the permissible environmental conditions.
NOTE!
The mains adapter and the stirrer drive do not have an ON/OFF switch. The system is ready for
operation as soon as it is plugged into the mains socket.
