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
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-
controller.
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
recorded (volumetric counter time out), the
measure underway is automatically
stopped.
