E 16
sensor 2 clip break
alarm
sensor 2 erroneously removed during
operation of the device
refit the sensor correctly and check correct sealing of the sys-
tem. Restart the system by means of an alarm reset.
sudden drop of plant pressure due to
a hose burst event or another fault
inspect the plant and check that there are no faults or
anomalous behaviours such as to result in a drop of plant
pressure. Restore the correct static pressure value and restart
the system by performing the alarm reset procedure.
E 20
sensor 1 pressure
measurement error
sensor internal fault
contact the service network and replace the sensor: to do
this, the plant must be de-energised and the device must be
emptied. Once the new sensor has been installed, proceed
with the alarm reset.
E 21
sensor 1 pressure
measurement over
range error
surpassing sensor maximum pres-
sure
check correct operation of the plant, of the expansion vessels
and of the safety relief valves. Surpassing the sensor maximum
pressure values is a very hazardous condition for the plant and
for persons: carry out a general check of the plant.
E 22
sensor 1 pressure
measurement under
range error
sensor internal fault
contact the service network and replace the sensor: to do
this, the plant must be de-energised and the device must be
emptied. Once the new sensor has been installed, proceed
with the alarm reset.
E 26
sensor 2 pressure
measurement error
sensor internal fault
contact the service network and replace the sensor: to do
this, the plant must be de-energised and the device must be
emptied. Once the new sensor has been installed, proceed
with the alarm reset.
E 27
sensor 2 pressure
measurement over

surpassing sensor maximum
pressure
check correct operation of the plant, of the expansion vessels
and of the safety relief valves. Surpassing the sensor maximum
pressure values is a very hazardous condition for the plant and
for persons: carry out a general check of the plant
E 28
sensor 2 pressure
measurement under
range error
sensor internal fault
contact the service network and replace the sensor: to do
this, the plant must be de-energised and the device must be
emptied. Once the new sensor has been installed, proceed
with the alarm reset.
E 23
sensor 1 temperature
measurement error
sensor internal fault
contact the service network and replace the sensor: to do
this, the plant must be de-energised and the device must be
emptied. Once the new sensor has been installed, proceed
with the alarm reset.
E 24
sensor 1 temperature
measurement over
range error
surpassing of maximum temperature
of sensor 1 (e.g. device internal
temperature above 100°C)
reduce system temperature and perform the plant safety shut-
down procedure, checking the adjustment systems and plant
safety systems. Excessively high temperatures can damage the
device and other components of the plant. Restart the plant
after having performed the foregoing checks and corrective
actions to guarantee that the maximum temperatures are
within the admissible values.
E 25
sensor 1 temperature
measurement under
range error
sensor internal fault
contact the service network and replace the sensor: to do
this, the plant must be de-energised and the device must be
emptied. Once the new sensor has been installed, proceed
with the alarm reset
E 29
sensor 2 temperature
measurement error
sensor internal fault
contact the service network and replace the sensor: to do this,
the plant must be de-energised and the device and the plant
must be emptied. Once the new sensor has been installed,
proceed with the alarm reset.
E 30
sensor 2 temperature
measurement over
range error
surpassing of maximum tempera-
ture of sensor 1 (e.g. device internal
temperature above 100°C)
reduce system temperature and perform the plant safety shut-
down procedure, checking the adjustment systems and plant
safety systems. Excessively high temperatures can damage the
device and other components of the plant. Restart the plant
after having performed the foregoing checks and corrective
actions to guarantee that the maximum temperatures are
within the admissible values.
E 31
sensor 2 temperature
measurement under
range error
sensor internal fault
contact the service network and replace the sensor: to do this,
the plant must be de-energised and the device and the plant
must be emptied. Once the new sensor has been installed,
proceed with the alarm reset.
