Error Codes - IKA RET basic Manual De Instrucciones

Any malfunctions during operation will be identified by an error
message on the display (E and F).
Proceed as follows in such cases:
Error code Cause
E3 Temperature inside device too high
E4 Motor blockage
E5 No temperature increase in sensor at
continuous temperature difference
E6 Break in safety circuit
E24 Surface temperature (temperature of
control sensor):
of the base plate is higher than the set
safe temperature limit
E44 Surface temperature (temperature of
safety sensor):
of the base plate is higher than the set
safe temperature limit
E25 Heating and switching element monitoring Heating off - Switch off device
E26 Difference between temperature of safety
sensor and temperature of control sensor
control temperature > (safety tempera-
ture + 40 K)
E46 Difference between temperature of safety
sensor and temperature of control sensor
safety temperature > (control tempera-
ture + 40 K)
If the actions described fail to resolve the fault or another error code is displayed then take one of the following steps:
- Contact the service department,
- Send the device for repair, including a short description of the fault.

Error codes

F Switch off device using the main switch (A)
F Carry out corrective measures
F Restart device
Effect Solution
Heating off - Switch off device and allow to cool down
Heating off - Switch off device
Motor off - Warning! Only to be carried out by authorized service personnel:
Carry out an internal test on the device to check the plug-in connector for the
motor
Heating off - Place the sensor in the medium
- Reduce the volume of the media
- Use a carrier fluid with better heat conductivity properties
- Replace the glass vessel with a metal pot
- Increase the "Time-out" period
Heating off - Plug in contact plug (L)
- Plug in PT 1000 contact thermometer / temperature sensor
- Replace faulty connecting cable, plug, or contact thermometer
Heating off - Switch off device until the surface temperature of the base plate is lower than the
selected safe temperature limit
- Set a higher safe temperature limit
Heating off - Switch off device until the surface temperature of the base plate is lower than the
selected safe temperature limit
- Set a higher safe temperature limit
- Set the safe temperature limit > 55 °C
