F Carry out corrective measures
F Restart device
E
rror code Cause Effect Solution
E3 Temperature inside device too high Heating off - Switch off device and allow to cool down
E4 Motor blockage Heating off
Motor off - Switch off device
- 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
E5 No temperature increase in sensor at
continuous temperature difference 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
E6 Break in safety circuit Heating off - Plug in contact plug (L)
- Plug in PT 1000 contact thermometer / temperature sensor
- Replace faulty connecting cable, plug, or contact thermometer
E24 Surface temperature (temperature of
control sensor):
of the base plate is higher than the set
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
E44 Surface temperature (temperature of
safety sensor):
of the base plate is higher than the set
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
E25 Heating and switching element monitoringHeating off - Switch off device
- Set the safe temperature limit > 55 °C
