10.1.1 Setting the excess temperature cutoff point
The cutoff point is set using the excess temperature dial
13
. It has a rough
scale of temperature values which only serves only as an approximate set-
ting for this cutoff point. However, the cutoff point can be set exactly using the
following procedure:
For example, if the bath liquid has a fire point of 60°C the unit should cut off
after reaching a temperature of 35°C:
Set the desired value using keys
7
to exactly 35°C.
After the circulator has reached this temperature, turn the excess tem-
perature dial
13
counterclockwise until the unit cuts off (fault message on
display
6
).
After the heat transfer liquid has had a chance to cool down, reset the
unit via the Reset key
2
.
Then set the temperature to the actual temperature (< 35°C).
The unit can now be used for temperatures below 35°C. As soon as 35°C is
reached the unit will switch off.
10.1.2 Testing the cutoff point
Set the temperature to a value higher than 35°C. Set the unit to heat up and
watch the digital display or thermometer. The value reached when the alarm
goes off is the actual cutoff temperature. Reaching of the cutoff point is indi-
cated at the display by the following message:
