3 / V145- JANNUARY 2005
From the 4
th
week / 2005, Tango machines will be produced fitted with the last software
version V145
This new version of software V145 was improved with the new electronic braking system of the
turntable “ABS system”, in order to insure an optimised stop of the turntable according its revolving
speed.
It includes also a new possibility to connect the tango to a cash computer system, in mode Credit/Debit
via the interface I/O (ref: 45333).
(Principle of Credit/debit mode: an authorisation is requested from the cash computer before the
beverage is dispensed from the Tango)
The configuration of the coffee machine in mode Credit/Debit is done directly from the display box in
menu “N. COINER” by validation of “CD”.
It includes also, all the improvements of the previous version. Remind of the most important points:
- a better precision in the diagnosis of the error codes which are 39 now (See list herewith);
- a best management of the error code detection: the furtive or false codes, provoked by electrostatic or
electromagnetic external disturbances, are now cancelled ;
- a double automatic starting order for pistons, in case of failure of the first start: from now , the risk of
blocking the machine is almost non existent.
- introducing of the STI function for 1 and 2 cup cycle.
Remind of the STI function : START INFUSION
This new parameter is common to all the cycles “coffee”. It allows controlling the start of the infusion, and
then the pre-infusion, mainly for the one cup cycles. The one cup quality is improved and more regular. That
means that the PS programming of the backward at – 04 is no longer needed and the programming of all the
parameters of “coffee” keys can be done only by the menu PP.
Regarding the improvement given with the STI on the 1-cup cycle, we decide to apply the STI to the 2-cup
cycles. The parameter STI for the 2-cup cycle is calculated from the 1-cup one. So the change of the STI
value acts simultaneously on the 1 and 2-cup cycles. The best value is the one giving the best compromise
between 1 and 2-cup cycles.
Note: the function STI is not working in the “ test cycle “ of the “GRINDERS SETTING” menu. In certain
cases of very fine ground, the pan could be “perforated” during the test cycle (without STI) while the infusion
will be quite correct during the normal cycle.
Programming of STI parameter
STI is programmable in the menu “Pro Packing Level” by pressing twice the + key to make appear STI = 00,
and the PRO key to make “00” blink, then + or - for increasing or decreasing the value. .
STI = 00 is the factory setting (perfect adjustment in 95% of cases)
STI = > 00 delays the infusion
STI = < 00 anticipates the infusion
STI = >60 neutralises the effect of STI and goes back to a functioning similar to the previous software
versions.
