The first entry in the error list will automatically be displayed on this operating line. By
pressing
, it is possible to switch between the error messages.
The controller can store a maximum of 10 error messages. The error signal will be
cleared only after the cause of the error has been removed. If additional errors are pre-
sent, they will be stored when storage capacity becomes available. Errors are displayed
in the order of their priority, that is, an error with priority 9 is displayed before an error
with priority 6, for example.
Errors occurring on this operating line (priority 5 and higher) can be passed on or visu-
alized by means of the alarm output (refer to auxiliary function ”Alarm output”, operating
line 151). The alarm output can be reset by pressing the + / - buttons simultaneously for
3 seconds (operating line 50). But the error in the error list remains.
