106 Error codes
› heat accumulation between heating plate and housing
› permitted ambient temperature exceeded
› heating switched off
› switch device off, leave to cool and switch on again
› change experiment
› observe maximum permissible ambient temperature
› motor blocked or overloaded
› heating switched off
› motor switched off
› reduce load torque or use smaller magnetic rods
› reduce target speed
› sensor not in medium
› volume of medium to be measured too large
› heat conductivity of medium to be measured too low
› heat conductivity of the vessel is too low
› in the case of indirect heating, the overall heat
conductivity resistance is too large
› heating switched 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
› defective connection cable
› heating switched off
› replace cable
Err. 13 – Hotplate safety sensor, open-circuit
› target / current different of the adjustable safety circuit
Causes
for minimum temperature monitoring
Effect › heating switched off
› after switching on, change the SAFE TEMP to a different
Solutions value; if this solves the issue, the previous value can be
reset by switching the device off and on again
Err. 14 – External temperature sensor, short-circuit
› short circuit in temperature sensor plug
Causes › short circuit in the cable or temperature sensor
Effect › heating switched off
› check the plug
Solutions
› replace the temperature sensor
Err. 21 – Fault during heating plate safety test
Causes › safety relay does not open
Effect › heating switched off
Solutions › switch device off, leave to cool and switch on again
Err. 22 – Fault during heating plate safety test
Causes › S_CHECK cannot generate H_S_TEMP
Effect › heating switched off
Solutions › switch device off, leave to cool and switch on again
Err. 24 – Heating plate temperature
is higher than the set safety temperature
› SAFE TEMP H (Hotplate) has been set to lower than the
current temperature of the heating plate
Causes › disconnection of heating plate control temperature sensor
Effect › heating switched off
› leave the heating plate to cool
Solutions
› set the SAFE TEMP H (Hotplate) higher
