15.1.1 Setting the excess temperature
The cut-off point is set with the excess temperature dial with
a rough scale of temperature values arranged around it. This
scale, of course, can only serve as an approximate setting
means for this cut-off point. However, the cut-off point can be
determined to act exactly if the following procedure is ad-
hered to:
If for instance a bath liquid has a flash point of 60
°
C the unit
should cut off after reaching 35
°
C at the latest:
1
First set the desired set value to exactly 35
°
C.
2
After the circulator has reached this temperature, turn
the excess temperature dial backwards very slowly (to
the left) until the unit cuts off (acoustic signal, alarm is
flashing).
3
Then set the set temperature to the actual temperature
(< 35
°
C).
4
Reset the unit via the reset key after the heat transfer
liquid has cooled down somewhat.
⇒
The unit can now be used for temperatures below
35
°
C. As soon as 35
°
C is reached, it is securely
switched off.
15.1.2 Testing the cut-off point
Set the set temperature to a higher value than 35
°
C, set the
unit to heat up and watch the digital display. The value indi-
cated when the alarm goes on is the real cut-off temperature.
The set overtemperature value can be read off at any time
in the ”Settings / Status” menu.
