KS 4000 i 1208
Cause
• Permitted ambient temperature has
been exceeded
• Ventilation slots or fan housing
blocked
• Motor seized or overloaded
• Value was incorrectly stored to memory
• EPROM switching error
• Short-circuit at temperature sensor
plug
• Short-circuit in connecting cable
or on temperature sensor
• SAFE Temp is set at a temperature
lower than the actual temperature on
the external temperature sensor
• SAFE Temp is set at a temperature
lower than the actual temperature on
the external temperature sensor
• Ventilation slots in incubation room
blocked
• Radial-flow fan does not rotaded
• Fault in the control or safety
temperature sensors
• Proper motion of appliance too
heavy
• Load is asymmetrical, has slipped or
is too heavy
• Power outage during operation
Effect Solution
Heating off • Switch off the unit. Allow it to cool down
and then switch on again.
• Clean ventilation slots or fan
housing
• Observe maximum permissible
ambient temperature
Heating off • Reduce the torque load
(load)
• Reduce the setpoint speed
Heating off • Repeat the calibration procedure
Heating off • Check the plug
• Substitude the temperature sensor
Heating off • Allow the unit to cool
• Set the SAFE Temp at a higher temperature
Heating off • Allow the unit to cool
• Set the SAFE Temp at a higher temperature
Heating off • Switch off the unit. Allow it to cool down
and then switch on again.
• Check fan or ventilation slots and
clean if necessary
The target speed was • Select a lower speed setpoint
reduced several times • Distribute load evely
automatically • Reduce load
Interruption of heating • Delete the display by pressing the
or shaking function shift key
