5.3.3 Operating example
A complete description of a front end set-up can be found in an application example in chapter 6.5
"Customer-specific application".
5.4 Error message display
The unit differentiates between two types of errors:
•
System errors: This group contains all unit errors, e.g. communication errors, hardware errors,
etc.
System errors are always displayed by a red rear illumination of the display field. As soon as all errors
have been removed the unit returns to the standard blue rear illumination.
•
Process errors: This group contains all application errors e.g. "Overrange", including all alarm limit
set points etc.
It is possible to define the unit reaction to each individual process error e.g. alarm message, colour
change etc. The colour change feature is set up in the operating address

Colour change (see chap. 6.4.3). Event text can be defined for any alarm set point condition. This
can be blended onto the screen. Additionally it is possible to set up if any error must be
acknowledged before the unit returns to its operating mode (

Event text-GW.Ack, see chap. 6.4.3).
If more than one system or process errors are active then these are displayed in chronological order
and the error displayed is always the oldest error.
System error messages
There is always a rear illumination colour change reaction from blue to red and an error message
display to any system or unit error. These must be acknowledged by pressing the ’
E’ key . Generally
system errors must be removed by E+H Service, with the exception of the "Config-error" which
can be removed by checking the unit set-up made.
Process error messages
Process errors are placed into an event memory, these can also be indicated by a colour change in
the display rear illumination (presettable). The exception is alarm set point conditions. Here an
event text can be defined and blended onto the screen, and/or the display changes colour (see chap.
6.4.3:

Display ).
Event memory
The last 20 process errors are stored chronologically in the event memory. These include time of
occurrance and counter values. The error messages in the event memory can be viewed using the
sub menu:
