If the bath temperature increases above the overtempera-
ture switch-off point: 

Two-tone alarm signal sounds.  

"Overtemperature" appears in the display. 

Heating switches off on both poles. 

Pump and chiller are switched off via the electronics. 

−

 

Rectify the cause of the malfunction.

Wait until the bath temperature has cooled below the cut-
off point or set the cut-off point higher than the bath tem-
perature. If "Overtemperature" appears in the display: 

−

 Unlock 

with

−

 

With longer periods of unsupervised operation you should 

check the overtemperature 

protection; to do this:

 

−

 

Slowly reduce T

max

 as described in (

Ì

 7.5.1). The thermostat should switch off when the actual tem-

perature is greater than T

max

. 

−

 

An alarm message (step 1-2, see above) should follow.

When the liquid level falls so far that the heaters are no longer 
completely covered with liquid, an alarm is triggered. 

Two-tone alarm signal sounds.  

"Low Level Pump" appears in the display. 

Heating switches off on both poles. 

Pump and chiller are switched off via the electronics.
