Disposal

At the end of its service life the stirrer is to be disposed of in accordance with the local regulations specified
for the disposal of electronic industry waste.
No connection to the mains (power cable damaged or power fail-
ure).

Check connection to the mains!
One or both plugs of the temperature sensor have been pulled
while the stirrer was running.

Connect temperature sensor again!
or:
Temperature sensor or its connection cable has been damaged
while the stirrer was running.

Replace temperature sensor (see "2.6 Technical Data")

Make sure that the cause of failure cannot reoccur in future
(e.g. cable touching the heating zone)!
Temperature sensor has caused a short-circuit.

Replace temperature sensor (see "2.6 Technical Data")
Error in internal data storage unit.

Contact the manufacturer!
The installed ventilator does not operate.

Contact the manufacturer!
The switching off after power failure is a normal safety function.

Switch on laboratory stirrer manually!
Your laboratory stirrer was or is disconnected from the mains.
This caused resetting of the residual-heat indicator function (as is
the case with all other functions of the device).

Switch off heater by pressing the right control knob, never by
pulling the mains plug!
This is possibly due to a failure in the electronic system of your
laboratory stirrer.

Return the stirrer to the manufacturer or your dealer to have it
checked and repaired!
