Speed - Normal Operations - IKA EUROSTAR digital Operating Instructions Manual

Version EUROSTAR power basic
( Fig. 1 )
Please first try switching the appliance off and on again to see
if operations can continue.If the fault does not clear after a rea-
sonable interval, please call our Service department.

At the same time as the yellow signal light comes on, further
details of the fault are shown by a fault code in the LCD display
(A):
ER 3: Internal temperature too high
Generally this fault can only occur if the permitted environ-
mental temperature is exceeded.
Remedy: Switch off appliance and allow to cool; switch on
again.
ER 4: Speed fault
This fault is indicated if the output shaft is locked or the speed
was higher then permitted. If there are jerky loads which
exceed three times the nominal torque, the appliance switches
itself off as a safety precaution.
Remedy: Check whether the output shaft is locked due to an
external cause. If it is, switch the appliance off and ensure that
the shaft can rotate freely. If not, switch the appliance off with-
out taking further steps. Then switch the stirrer on again.
If any other fault code is indicated, please initially check
whether operations can be continued. If the fault cannot be
rectified by the means described, contact our Service depart-
ment. In each case we need to know which fault code was
indicated. This makes fault-finding easier and allows us to
make an initial diagnosis.

Speed - normal operations

Speed - regulated (no variation in speed)
The speed is monitored and regulated by computer control.
The NOMINAL value is constantly compared with the ACTUAL
value of the output shaft and variations corrected. This gua-
rantees 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.
Version EUROSTAR power basic
The speed is set using the front knob (B). During normal
opera tions the speed value on the scale corresponds to the
speed of the output shaft in revolutions per minute (rpm).
Versionen EUROSTAR power control - visc,
EUROSTAR power control - visc P1,
EUROSTAR power control - visc P4,
EUROSTAR power control - visc P7, and
EUROSTAR power control - visc 6000
The speed is set with the front knob (B). The ACTUAL value is
indicated directly in rpm (1/min.) on the LCD display (A). The
NOMINAL value set corresponds to the ACTUAL value.
When using the EUROSTAR power control – visc 6000 the dis-
played ACTUAL value must be multiplied by a factor of 10.
