2.2 Evaluation of faults
A fault indicator (information or error message) from the unit is displayed through the
integrated LED on the controller (see Fig.1,
ä
). The fault indicators > Info < and > Error <
are displayed by differently coloured LEDs:
LED >>
Info = Green
LED >> Error = Yellow
Information and error messages can be evaluated via the flash code and the fault over-
view (see section 2.3. fault overview).
The following information and error messages are defined:
In relation to flash code, the LED flashes 32 times in quick succession (approx. 100
msec). There is a 4 second pause after each cycle (32 flashes). A total of 32 possible
errors can be represented. The error to be displayed is represented in the cycle by longer
flashes (approx. 500 msec).
Fault example for >Error< 2 and 9:
Reset function (error messages, information messages, warnings)
The controller can be RESET via the slide switch. For this purpose, quickly switch
through the 3 operating stages via the slide switch settings 1-2-3-2-1, starting with
