The built-in microprocessor controls not only the programming sequence but the information system too.
The individual phases of the programming sequence are displayed as Flash-Code. The following messages can
be distinguished:

Lock-out diagnoses
In case of a failure the LED is permanently illuminated. Every 10 seconds the illumination is interrupted by a fl ash
code, which indicates the cause of the error. Therefore the following sequence is performed which is repeated as
long as the unit is not reset.
Sequence:
illuminated phase
for 10 sec for 0.6 sec
