710 (W710) Warning
C B>Set span too small. Not
allowed. – Values for calibration (e.g. lower
range value and upper range value)
are too close together.
– Adjust calibration to suit sensor.
(

description for MINIMUM SPAN.)
51
– The sensor was replaced and the
customer-specific configuration does
not suit the sensor.
– Adjust calibration to suit sensor.
– Replace sensor with a suitable
sensor.
– Unsuitable download carried out. – Check configuration and perform
download again.
711 (A711) Alarm
B B>LRV or URV out of edit limits – Lower range value and/or upper
range value undershoot or overshoot
the sensor range limits.
– Reconfigure lower range value and/
or upper range value to suit the
sensor. Pay attention to position
factor.
37
– The sensor was replaced and the
customer-specific configuration does
not suit the sensor.
– Reconfigure lower range value and/
or upper range value to suit the
sensor. Pay attention to position
factor.
– Replace sensor with a suitable
sensor.
– Unsuitable download carried out. – Check configuration and perform
download again.
713 (A713) Alarm
B B>100% POINT level out of edit
limits – The sensor was replaced. – Carry out calibration again. 39
715 (E715) Error
C
Factory
setting:
Warning C>Sensor over temperature – The temperature measured in the
sensor is greater than the upper
nominal temperature of the sensor.

– Unsuitable download carried out. – Check configuration and perform
download again.
716 (E716) Error
B
Factory
setting:
Alarm B>Process isolating diaphragm
broken – Sensor defective. – Replace sensor. 24
717 (E717) Error
C
Factory
setting:
Warning C>Transmitter over temperature – The temperature measured in the
electronics is greater than the upper
nominal temperature of the
electronics (+88 °C).
– Reduce ambient temperature. 34
– Unsuitable download carried out. – Check configuration and perform
download again.
718 (E718) Error
C
Factory
setting:
Warning C>Transmitter under temperature – The temperature measured in the
electronics is smaller than the lower
nominal temperature of the
electronics (–43 °C).
– Increase ambient temperature.
Insulate device if necessary.
35
– Unsuitable download carried out. – Check configuration and perform
download again.
720 (E720) Error
C
Factory
setting:
Warning C>Sensor under temperature – The temperature measured in the
sensor is smaller than the lower
nominal temperature of the sensor.
