Drive
The speed can be adjusted continuously over two speed range (speed range I, speed range II ) with the
knob (B, see Fig. 1).
Motor protection
The stirring instrument is suitable for continuous
operation. The motor current is limited electronically.
The instrument has an anti-stall and anti-overload
system.
Speed – normal operation
Speed - regulated (no variation in speed)
The speed is monitored and regulated by pro-
cessor 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 (B, see Fig. 1).
During normal operations the speed value on the
display (C, see Fig. 1) corresponds to the speed of
the output shaft in revolutions per minute (rpm).
Correct use
• Use
For mixing/stirring liquids with low to high vis-
cosities by various stirring tools.
Intended use: Stand device (chuck points down)
• Range of use (indoor use only)
- Laboratories - Schools
- Pharmacies - Universities
This instrument is suitable for use in all areas except:
- Residential areas
- Areas that are connected directly to a low-voltage
supply network that also supplies residential areas.
The safety of the user cannot be guaranteed:
- If the instrument is operated with accessories that
are not supplied or recommended by the manu-
facturer
- If the instrument is operated improperly or con-
trary to the manufacture’s specifications
- if the instrument or the printed circuit board are
modified by third parties.
If a fault occurs, a safety circuit immediately switches
off the motor permanently through a relay in the
power board. A fault occurs if the safe functioning
of the instrument is compromised.
