Auto-Test Components; Diagnostic Programming - Rancilio CLASSE 6 E Original Instructions Manual

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

10.2. Auto-test components

The electronic board E06 enables techni-
cians to individually test and verify the operation of
all electronic components of the machine.
In order to utilise this function it is necessary to enter
the electronic board by dismantling the left panel
of the machine (a descriptive label of the auto-test
function is attached to the inside of the panel).
The sequence is guided by means of the display at
the centre of the electronic board.
Since the auto-test is conducted with machine
open, be careful not to touch any live part.
To enter the auto-test menu proceed as follows:
- Switch off the machine.
- Push and hold button A of the first group's push-
button panel (fig. 8) and turn on the machine.
- Buttons A, B, C and D (fig. 8) light up and the
board display indicates 0 (auto-test menu in ope-
ration).
In this menu only buttons A, B, C, D of the first group
operate with the following functions:
A = Button + (increases the number/letter correspon-
ding to the component to be activated).
B =Button – (decreases the number/letter correspon-
ding 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 seconds) (*)
5 = electro-valve charge (ON for 3 seconds)
6 = pump motor (ON for 3 seconds)
7 = 1st heating element (ON for 5 seconds) (**)
8 = 2nd heating element (ON for 5 seconds) (**)
9 = 3rd heating element (ON for 5 seconds) (**)
64
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 (heating element ON until
boiler 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 or B (fig. 8) to scroll through display
numbers and letters. Once you reach the desired
letter or number (component you wish to control)
press button C to activate.
Button D stops activation of the component.
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
boiler will not be filled (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
conducted with the machine open, be careful
not to touch any live parts.
Malfunctions are shown on the display situated at
the centre of the electronic board.
