Malfunction without error-no.
In some cases, it will be technically impossible to display an "irregular functioning" of the instal
-
lation by a definite error number. An alleged error may by all means also be due to "correct" cau
-
ses. For this reason the list shown hereafter has been established, which contains the probable or
already encountered irregular functioning, their possible causes as well as the corrective action
(error elimination) to be taken.
