3.3 Safety devices installed
-
Three safety valves protect the machine from over-
pressures in the network meant for producing hot
water for coffee, for hot drinks and for steam.
-
Each boiler unit is protected against over-heating by way
of a thermostat.
-
Three microswitches control the position of the drip tray
(ref.15, fig. 1), the grounds tray (ref. 17, fig. 1) and the
front door (ref. 13, fig. 1) If one of the components is not
correctly positioned, the relevant microswitch locks the
machine and the display will indicate the component out of
position.
Two pulse counters (one electronic, the other mechanical)
count the number of dispensing instances and allow the
programming of routine maintenance interventions by the
maintenance technician.
-
The greater part of electrical components is fed with a
voltage of 24 V dc.
