7.2 STARTING OPERATION AND USE
Improper use may damage the device.
Observe therefore these instructions:
•
Use a stirrer up to the specified diameter max Ø 300 mm.
• Load the device in such a way that the speed would not drop con-
siderably or that it would stop.
Check if the data on the rating plate correspond with the actual mains
voltage. The device´scheduled for 230V can be plugged to 220V/240V
mains.
7.2.1 Fixing a stirrer:
Screw tools with thread M14X2 as far as possible in the tool mount and
tighten properly with an open-end wrench (22mm) from among the ac-
cessories.
7.2.2 Switching on and off:
By pressing the switch button the device is brought into operation and it
stop when is relieved.
7.3.3 Permanent run:
By pressing the switch button o the stop and simultaneous pressing the
arresting pin permanent run is achieved. By subsequent pressing and
relieving of the switch button the permanent run is interrupted.
7.3.4. Remove the stirrer:
Fit a flat open-end wrench (22mm) on the hexagon end of the tool
(whisk) and unscrew the tool from the spindle by turning it to the left.
7.3 ELECTRONIC MOTOR CONTROL
7.3.1
Starting current limiting:
The electronically controlled smooth start takes care that the machine
starts without jerk. In this manner, the splashing of thin liquid materials
is prevent at the same time when switching on the machine. As a result
of the machine´s reduced starting current, a 16A fuse is sufficient
7.3.2
No-load speed reduction:
The electronic control reduces the no-load speed of the machine which
results in reduced noise and wear of motor and gear.
7.3.3
Speed pre-selection:
With the speed control, the speed can be continuously pre-selected. The
necessary speed is dependent on the type of material to be mixed. It is
recommended that it be confirmed. With a practical trial.
7.3.4
Speed selection
Two rpm ranges can be preselected with the speed selector switch
(6).
Speed 1: 150 min – 300 rpm
Speed 2: 300 min – 650 rpm
The necessary speed depends on the type of the material mixed and it is
recommended to verify it by practical test.
7.3.5 Constant Electronics
The constant electronic keeps the Speed between no-load and load
nearly constant and ensure uniform mixing of the materials.
7.3.6 Electronic overload protection:
In case that the machine is extremely overloaded, an electronic overload
protection protects the motor from damage. In this case, the motor stops
and restarts only after the feeding pressure is reduced.
7.3.7 Temperature-dependent overload protection
To protect the motor from overheating at extreme permanent load, it is
switched off by the protective electronic system when a critical tem-
perature is reached. After a cooling-down period of approx. 3-5 min. the
machine is again ready for use and can be fully loaded.
When the machine is warmed by use, the temperature-dependent over-
load protection reacts earlier as a result.
