Operation with programmer:
If
fault
4
or
5
occurs while a program is running:
a
return unit for servicing.
Operation without programmer:
If
fault
4
occurs, the identification is considerably dis-
turbed by external heat flow.
Arrange for constant temperature conditions and
try another identification run.
As this fault only occurs during the identification,
switch off the identification if necessary:
Select CONTROL, then INT-EXT, then FUZZY-ID
and define whether to switch on or off the identifi-
cation.
INTERNAL EXTERNAL
If the fault occurs repeatedly:
return unit for servicing.
If
fault
5
occurs, this indicates the influence of a high
level of external cooling or heating during identification.
Reduce the influence and try another identifica-
tion run.
If the fault occurs repeatedly:
Please contact the Thermo Haake product spe-
cialists.

SRAM (SF,
dt):
F09
If
a set temperature is selected that is less than 5°C
above the actual temperature, this set value is reached
without identification. In this case the control parame-
ters are taken from the SRAM.
If these values are faulty, they are not accepted by the
Fuzzy control, and fault
9
occurs.
=S
Select a set temperature that is more than
5°C
above the actual temperature. This causes the
Fuzzy control to carry out an identification in order
to determine new control parameters.
