• Straightforward checking of plant
• Fault tracing is made easier

The display shows "Er" when an error has occurred.
Display

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.
