IKA KS 4000 i control Mode D'emploi page 22

Error code Description
Er 3 Temperature inside unit too
high
Er 4 Differanceberween setpoint and
actual speeds is too large
Er 8 The calibration value of the
temperature sensor is outside
the limit value
Er 14 External temperature sensor,
short-circuit
Er 16 External temperature sensor has
exceeded the SAFE Temp
Er 17 Temperature sensor - Incubation
- room has exceeded the SAFE
Temp
Er 26 Difference between the internal
control and safety temperature
sensors too large
Er 60 Power outage
Cause
• Permitted ambient temperature has been
exceeded
• Ventilation slots or fan housing blocked
• Motor blocked or overloaded
• Fault in calibration procedure
• 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
• 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
Interruption of heating or • Delete the display by pressing the shift key
shaking function
