7.11 Alarm condition
Boiler (filling) level time out
This alarm condition occurs whenever the
water level is too low or the level probe
remains uncovered. In such a case the key-
board leds flash and an alarm message
appears on the display.
The filling stage is automatically engaged
and to cancel the alarm conditions switch
the machine off and then on again.
Lack of volumetric counter impulses
On starting a volumetric control coffee
cycle, the correct function of the volumetric
counter is checked by the reading of the
number of impulses sent by the same to
the micro-controller.
Should no impulses by recorded for a pe-
riod exceeding 5 seconds the LED relative
to the selected measure begins flashing (ie.
the led relative to key T4).
After one minute in which no impulses are
recorded (volumetric counter time out),
the measure underway is automatically
stopped.
