Auto-Test Components; Diagnostic Programming - Rancilio EPOCA E-S-S-Tank Use And Maintenance

By pressing button C the factory setting of 1-bar is set.
After having regulated the desired pressure, press D
to save the setting and quit the menu.
ATTENTION: during programming, water dispensing
is interrupted while heater pressure control is in use.

10.2. Auto-test components

Electronic board E14 foresees auto-testing with
which it is possible to verify operation of the electric/
electronic components of the machine one by one.
In order to utilise this function it is necessary to enter
the electronic card by dismantling the left panel of the
machine (a descriptive label of the auto-test functions
attached to the inside of the panel).
The sequence is guided by means of the display at
the centre of the electronic card.
Since the auto-test is carried out on the open
machine, be careful not to touch the parts
under voltage.
To enter the auto-test menu proceed as follows:
 Switch off the machine.
 Keeping push button A of the first group pressed
(Fig. 3) switch on the machine.
 Push buttons A, B, C and D (Fig. 3) light up and
the card display indicates 0 (auto-test menu in
operation).
In this menu only push buttons A, B, C, D of the first
group operate with the following functions:
A = Push button + (increases the number/letter cor-
responding to the component to be activated).
B = Push button – (decreases the number/letter
corresponding to the component to be activated).
C = Enter (component activation).
D = ESC (quit component activation).
During activation of the component, the display point
will flash.
Each value indicated on the display corresponds to
the auto-test of the following components:
0 = auto-test ON
1 = electro-valve group 1 (ON for 3 seconds)
2 = electro-valve group 2 (ON for 3 seconds) (*)
3 = electro-valve group 3 (ON for 3 seconds) (*)
4 = electro-valve hot water supply (ON for 3 sec-
onds) (*)
5 = electro-valve charge (ON for 3 seconds)
6 = pump motor (ON for 3 seconds)
7 = 1st heater resistance element (ON for 5 seconds)
(**)
8 = 2nd heater resistance element (ON for 5 sec-
onds) (**)
9 = 3rd heater resistance element (ON for 5 sec-
onds) (**)
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)
H = Relay test for boiler over pressure (Switch OFF
the relay)
(*) 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. 3) scroll display numbers
and letters after being positioned on the letter cor-
responding 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
Electronic board E14 allows the operation of diag-
nostic 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 board.
Possible failures in course are indicated on the elec-
tronic card display by means of numbers or letters
(in case of more than one failure simultaneously,
the corresponding numbers/letters are alternately
displayed):
