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.
