Water absence indication (water reserve)
Function:
The water level is monitored by a capacitive sensor, located one
third up the water tank wall.
If the electronic system detects that the water is below the relative
level by means of the sensor, a water reserve of 200 pulses of the
flow meter remains available for the dispensing process.
The product dispensing process is then completed.
If a dispensing process ends after the sensor has intervened (in the
reserve), the "water absence" indication continues to be displayed
as from the next dispensing process
Empty residual water tank indication
Function:
The residual water level is monitored by a capacitive
sensor. The sensor is located approximately half way up
the upper edge of the residual drip tray. To make the best
Sensor
of the tray capacity, the sensor is positioned near a dam
device. In this way, the residual water tray fills up to the
upper edge and overflows inside and when it reaches
the sensor, it triggers the "empty residual water tank"
indication.
