Error Codes - IKA KS 3000 i Mode D'emploi

Error codes

An error is indicated by an acoustic signal and an error code is displayed.
E. g.:
If faults cannot be eliminated directly, you must perform a RESET (see „Resetting parameters to the factory settings")!
If the faults still cannot be eliminated, the appliance must be inspected by a technical service.
Error Description
code
Er 3 Temperature inside unit too high
Er 4 Differance between setpoint and
actual speeds is too large
Er 8 The calibration value of the tempe- • Fault in calibration procedure
rature 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
PC 1 In remote operation (PC) with
watchdog function 1 (WD) enabled:
No communication between
PC and unit
PC 2 In remote operation (PC) with
watchdog function 2 (WD) enabled:
No communication between
PC and unit
Cause
• Permitted ambient temperature has
been exeeded
• Ventilation slots or fan housing
blocked
• Motor seized or overload
• 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 rotate
• Fault in the control or safety
temperature sensors
• Power outage during operation
•PC does not send data during the
watchdog time
• The connection/cable to the PC is
broken
• PC does not send data during the
watchdog time
• The connection/cable to the PC is
broken
Effect Solution
Heating off • Switch off the unit. Allow it to cool down
and switch on again.
• Clean ventilation slots or fan
housing
• Observe maximum permissible ambient-
temperature
Motor off • Reduce the torque load
(load)
• Reduce setpoint speed
Heating off • Repeat the calibration procedure
Heating off • Check the plug
• Substitude the temperature sensor
Heating off • Allow the unit to cool down
• Set the SAFE Temp at a higher temperature
Heating off • Allow the unit to cool down
• 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 • Delete the display by pressing the
or shaking function shift key
Heating off • Change the watchdog time
Motor off • Send data from the PC within the
watchdog time
• Check the connector cable and plug
The setpoint temperature • Change the watchdog time
is set to the WD safety • Send data from the PC within the
temperature watchdog time
The setpoint speed • Check the connector cable and plug
is set to the WD safety
speed
