6. Error indications

6. Error indications
The display controls several possibilites of errors and shows them if required in the display.
Overflow behavior
If a process value (Integer value) is transfered, that exceeds the display range of the
display, then the display shows a fast flashing display with the incorrect value, this means
the available significant digits. The minus sign needs its own digit. The same happens in
operation type 5, if segments are triggered, that are not available in the display. In this case
the defined display segments are flashing with a high frequency.
Error indications
During the starting sequence a check of the configuration is done. Furthermore an error
number / warning number can be found in the Gateway. It then alerts a checksum error, an
EEPROM error or a Profibus error.
After this the device processor starts with the cyclic scanning of the display segments that
need to be displayed, which state the operating mode.
Source of error
Checksum error
Gateway error
EEPROM error
SPC3 error
PCHECKSUM error
DATA overflow
Data exchange error
Configuration error
Watchdog overflow
If an initialisation error occurs, the error indications appers directly in the display. At an
operating error the display reacts with fast flashing of the current dates for at least 10
seconds.
Occured errors can be called up by shortly pushing the [▲] or [▼] key. The single errors
can be called up by pushing the keys shortly several times. Each single error can be
deleted by pushing the [▲] or [▼] key for approx. 1 second.
If no error did occur then „noE" appears. After the error indication the display changes back
automatically into operting mode after approx. 7 seconds.
