Diagnostic Programming - Rancilio EPOCA 1 E Original Instructions Manual

A = push-button panel/LED (pressing each button,
the corresponding LED flashes)
B = volumetric meter group 1 (100-pulse supply)
C = volumetric meter group 2
(100-pulse supply) (*)
D = volumetric meter group 3
(100-pulse supply) (*)
E = heater level (water charge if level is not
sufficient)
F = pressure transducer (heater resistance ON until
heater pressure set-point is reached)
(*) Only for predisposed machines.
(**) Only for machines with star resistance connec-
tion.
Some of the auto-test operations involve the
dispensing of hot water and steam; take care
in order to avoid possible burns.
Push buttons A and B (Fig. 6 - 6A) scroll display
numbers and letters after being positioned on the
letter corresponding to the component to be tested.
Press C to activate;
Push-button D quits component activation.
To quit auto-test menu switch off the machine then
switch on again.
Note: Press esc to quit operations A, E and F
During auto-test, brewing will be interrupted and the
heater will not be fed (except for test F).

10.3. Diagnostic programming

Electronic card E 06 allows the operation of dia-
gnostic programming with which possible machine
failures or malfunctions can be signalled.
In order to utilise this function it is necessary to ac-
cess the electronic card by dismantling the left panel
of the machine (a descriptive label of the auto-test
function is attached to the inside of the panel).
As the use of diagnostic programming is car-
ried out on the open machine, take care not
to touch the parts under voltage).
Malfunctions are visualised on the display situated
at the centre of the electronic card.

at the centre of the electronic card
Possible failures in course are indicated on the
electronic card display by means of numbers or let-
ters (in case of more than one failure simultaneously,
the corresponding numbers/letters are alternately
displayed):
1 = Time-out Heater filling level: time limit for correct
heater filling has been exceeded.
2 = Time-out Heater pressure set-point: the time
limit to reach heater pressure set-point has been
exceeded
3 = Electronic card 12Vdc short: short circuit in the
electronic card E 06
4 = Capacity level sensor 12Vdc short: capacity level
sensor supply has short-circuited. (*).
5 = Pressure transducer 12Vdc short: pressure tran-
sducer supply has short-circuited.
6 = Volumetric counter 12Vdc short: short circuit on
the supply of volumetric counters.
 = 5Vdc push-button panel short: the push-button
panel has short-circuited.
 = Transducer/probe short on output signal: short
circuit on output signal from the pressure tempe-
rature probe / transducer.
 = Open transducer/probe signal: the output signal
from the temperature probe/transducer has been
interrupted.
A = Absence of volumetric counter impulses group
1: the volumetric counter of the first group is not
transmitting impulses to the electronic card.
B = Absence of volumetric counter impulses group 2:
the volumetric counter of the second group is not
transmitting impulses to the electronic card. (*).
C = Absence of volumetric counter impulses group
3: the volumetric counter of the third group is not
transmitting impulses to the electronic card (*).
(*) Only for predisposed machines.
The failures identified by numbers 1 to 9 block
machine utilisation. Apart from the failure being in-
dicated on the display, the push-button panel LED
will flash simultaneously informing the user of the
malfunction.
After having identified and resolved the failure,
switch the machine off and then on again for normal
utilisation.
NOTE: The problems identified with the letters A, B
and C do not interrupt the functions of the machine.
They are identified on the display and during dispen-
sing from the corresponding group, the LED of the
button pressed will flash.
