Fault
1 : Fault during identification
If at the beginning of the identification the set tempera-
ture is changed by the user so that the temperature
difference between the actual temperature and the
new set temperature is smaller then
5"C, fault 1
occurs.
Switch off and on unit.
or
RESET actuate in the SETUP-2 menu.
If you should set the desired temperature via the
I/O card, please
see chapter 23.7.
Fault 4 and Fault 5: Fault during identification
During the identification, to determine ideal control
parameters the Fuzzy control repeatedly measures
temperature gradients, delay times etc.
The identification result, which
is made up of a great
number of measurements,
is continually checked for
plausibility.
In case of discrepancy en error message
appears.
In order to remove the fault two different modes have
to be distinguished:
