Cause Remedy
The temperature sensor
for calculating the vapor
temperature is not
connected, defective or
the temperature is above
the measured range. ‒ Vapor sensor broken
‒ not connected
‒ above the temp. range Let the boiling temperature
sensor cool
Connect the vapor
temperature sensor
Perform visual check
Contact service
The vapor temperature
sensor is defective or the
temperature is below the
measured range ‒ Short circuit of the vapor
sensor
‒ below the temp. range
Heat the boiling
temperature sensor
Perform visual check
Contact service
The Auto
accurate
sensor
is defective or the
temperature is below the
measured range.

Cause Remedy
A temperature above the
safety temperature was
measured in the heating
bath. The temperature
measurement is defective
or the medium filled in
was too hot. ‒ Heating bath safety
temperature is exceeded
Switch off units
Cool the heating bath
medium
Contact Service if media was
not filled in
The heating bath is
completely evaporated.
Please refill the heating
bath medium. ‒ Heating bath is completely
evaporated.
Deactivate the unit
Check if the maximum
temperature limiter has
responded. If yes, reset
(see chapter “Maintenance,
cleaning, service” –
“Maintenance”)
Fill in heat transfer fluid
An illogical temperature
difference was measured
between the heating bath
sensors. The temperature
measurement is defective. ‒ Heating bath sensor variance
> 10 K
Contact service
The temperature sensor
for the heating bath
control is defective.
(hardware monitoring
unit) ‒ Sensor monitoring via
hardware
‒ Heating bath sensor is broken
or short circuited
Contact service
The temperature sensor
for the heating bath
control unit is broken or
bath medium that is too
hot was filled in. ‒ Heating bath sensor is broken
‒ Heating bath is more than
217 °C
Contact service
The temperature sensor
for the heating bath
control unit is defective or
bath medium that is too
cold was filled in. ‒ Heating bath sensor short
circuit
‒ Heating bath is below 0 °C
Switch off units
Cool the heating bath
medium
