7.0 GUIDE TO THE MOST COMMON FAILURES
7.1 ALARMS
When an alarm occurs, it has generally the effect to swicth off
outputs and block the possible supply. All alarms can be blocked,by
going to Maintenance and pressing the Reset key. In WinBianchi
there must be the possibility to block an alarm.
7.1.1 DISPLAYED BLOCKING ALARMS
RLine 1: Out of order
Line 2: EEprom Error
It is activated if an error is detected in
the EEprom. By performing the reset ope-
ration the factory data will be fi lled in the
EEPROM (only if there is this alarm).
Line 1: Out of order
Line 2: Token device error This alarm is active only if the Executive
or MDB token device is enabled. it occurs in
case of error in the communication between
card and token device or the token device
is not detected.
- Executive: there is a delay of 60 seconds
from the moment the token device is not
detected to the moment the alarm is activa-
ted.
- MDB: the delay is of 10 seconds after
switching on, therefore of about 2 seconds.
- Scale Factor : This alarm is active only if
the Executive token device is enabled (not
in Price Holding). It occurs if the division
between a programmed piece and the base
coin received from the token device exceeds
the value of 250. This alarm is self-setting.
Line 1: Out of order
Line 2: Slave Alarm It occurs if all slaves linked to Master card are
on alarm. Therefore, no supply is possible.
7.1.2 ALARMS DISPLAYED UNDER MAINTENANCE
Under maintenance, alarms and signallings will be displayed.
Signallings are a particular type of alarm which does not interrupt
the machine normal operation. For both alarms and signallings
there is a further distinction between stored and not stored. The
stored alarms or signallings stay also after the card switching off
and on
7.1.2.1 Stored alarms
ECM EEprom error
It is activated if an error is detected in the
EEprom. By performing the reset operation
the factory data will be loaded in the eeprom.
(only if there is this alarm)
EBI Translator
It occurs if the 10 second timeout expires
during the spout translator movements
7.1.2.2 Unstored alarms
EAJ Scaling factor
This alarm is active only if the Executive token
device is enabled (not in Price Holding). It
occurs if the division among one of the pro-
grammed pieces and the base coin received
by the token device is self-setting.
ECE Out of order
It is activated if the communication between
the Mother board and and the Master is in-
terrupted
EBA Cup
It is activated in one of the following cases:
1. The 90 second timeout for the rotation of
the cup column expires
2. The 10 second timeout for the cup release
expires
EDP Water level It expires after 2 seconds from the detection
of the micro lack of water. It switches off the
resistor and reinitializes the time out for E12
and E13.
EC1C Tcaffe<60°C
It refers to boiler 1. It occurs if at the reset
temperature minus 15 ° C, in 15 minutes, or if
during the normal operation the temperature
is below 60 ° C for 15 minutes. It is valid for
single boiler or coffee boiler if the double
boiler is enabled
EC2C Tsoup<60°C
It refers to the boiler 2. It occurs only if the
double boiler is enabled and if at the reset,
the set temperature minus 15 ° C is not rea-
ched. in 15 minutes, or if during the normal
operation the temperature is below 60 ° C
for 15 minutes.
EDF Sugar
It occurs if the 10 minutes time out expires
during the sugar conveyor.
EGN Too full
It is activated after 2 seconds from the de-
tection of micro too full of the liquid collecting
bowl.
ECK No Espansion
It occurs if components managed by any
expansion are enabled.
7.1.2.3 Stored signallings
EDT Grinder X
It is activated if the programmed grinder
expi res. The message “No coffee” is di-
splayed. The amount is re-credited only in
case of instantaneous grinding. X = 1 or 2
EEK Group
It is activated if programme coffee group
timeout expires. The message “No coffee” is
displayed. The amount is re-credited.
EEJ No Group
It is activated if the micro group presence is
NA
EFN ESP Pump
It is activated during water supply of cof-
fee if at least 10 cc are not supplied in the
programmed pump timeout. The message
“Only expresso” is displayed. The amount is
re-credited. The amount is re-credited. The
boiler resistance will be switched off up to the
error reset
EFN SOL Pump
It is activated during soup or hot water sup-
ply if at least half a dose in the programmed
pump timeout is supplied. The message “No
coffee” is displayed. The amount is re- cre-
dited if no hot water was being supplied. The
boiler resistor will be switched off up to error
reset.
EDU Dose vol 1
It is activated if after the release phase the
micro dose is pressed. The message displayed
is “ No coffee”. The amount is re-credited.
EDU Dose vol 2
It is activated if after the coffee release phase
the micro dose is pressed. The message “
No coffee” will be displayed. The amount is
re-credited.
EDF Stires
It is activated if the stirer timeout expires of
10 “. With this active signalling, the spoons
will not be supplied any more.
EDM NTC X Slave Y It occurs if the temperature probe is short
circuited or the circuit is open. The resistance
is off if NTC is in short circuit or open. When
on, there is an expected delay of 30 seconds
before the alarm has occurred
NTC 1 – Relevant to the power card
NTC 2 – Relevant to the expansion 1
Slave Y indicates which D.A. slave belongs
to.
