ALARM CONDITION
BOILER (FILLING) LEVEL TIME
OUT
This alarm condition occurs whenever the wa-
ter level is too low or the level probe remains
uncovered. In such a case the keyboard 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-con-
troller.
Should no impulses by recorded for a period
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 re-
corded (volumetric counter time out), the mea-
sure underway is automatically stopped.
