3 : PAN Confi guration
Below are two examples of a machine with PAN confi guration with
the following data:
Tank temperature = 2°
Delta temperature = 2°
Offset temper. = 0
Delta safety = 5 ( therefore "safety temper."=5+2= 7°). Safety
time =2 (hours)
1) Assume that the loader takes 15' to recharge the machine
therefore the cell temperature measured by the probe when
the machine is closed again will be 12°.
Then the tank temperature will be higher than the set "safety
temperature" (5+2 = 7° ), then the buzzer warns ( for 30 sec.)
that the loader must enter code 98 within 30 sec. to inhibit the
stop of the two bottom cabinets.
If the loader enters 98 within 30 sec. the "Safety time" function
will intervene and being this time set on 2 hours, it will enable
the machine to dispense the perishable products for 2 more
hours,after which and with the tank temper.fallen below 7°, the
normal conditions will be restored. If after these two hours the
tank temper. remains higher than 7°, that means that there are
problems and the machine will stop the two bottom cabinets.
2) Assume that the mains power is off, a fi rst time (A ) for 10
minutes, a second time (B) for 30 minutes:
(A) If the machine remains at stop for 10 minutes, the tank
temperature will remain below the 7° of the "safety temper." and
therefore when the power is on again, everything will operate
as before.
(B) If the machine remains at stop for 30 minutes, the tank
temper.will exceed 7° and therefore with power on again the
buzzer will beep for 30 sec, and if nobody enters code 98, the
two bottom cabinets will be inhibited.
In case of PAN confi g., defrosting is always set every x hours,
but its duration cannot be set (for x minutes) as the unskilled
customer may set such a long stop duration for the compressor
so to increase the tank temper. above the "safety temper." with all
subsequent problems (moreover the European regulations require
a "guarantee" check on perishables).
In this case the stop duration for the compressor is no longer
established by the time but by an increase in temperature fi xed
in +3° for all machines:
When the tank temper. exceeds the set temperature (2°) of 3°,
the compressor will start again. The tank must obviously be insu-
lated to allow a complete defrosting during the stop period of the
compressor If it is not properly insulated, the stop time is so short
that the evaporator is unable to defrost in max.hot moments.
(Then it is maybe possible to enter a min.fi xed time of 10' in ad-
dition to the fi xed delta of 3°).

The X indicates the slave number linked to the MASTER distributor.
Displayed and modifi able in WB only. In the Machine programming
this parameter can be modifi ed only from Options in the parameter
Type BVM600.
Boiler 1 Slave X Selects the type of the main boiler to be
installed [Espresso, Instant Stainl.steel,
Instant Polysulfone, none] This menu is
available only if a type of machine BVM970,
BVM950, BVM920 has been chosen. The
wording Slave X shows the slave number
linked to the MASTER distributor.Managed
by WinBianchi only.
Boiler 2 Slave X Selects the type of the second boiler to
be installed [Instant Stainl.steel, Instant
Polysulfone, none] Menu available only with
Machine BVM970. The wording Slave X shows
the slave number linked to the MASTER di-
stributor.Managed by WinBianchi only.
Grinder Slave X Selects grinder management [Yes/No] If grin-
der Management NO the fi rst three product
boxes are dedicated exclusively to ground
coffee. The wording Slave X shows the slave
number linked to the MASTER distributor.
Managed by WinBianchi only.
Double grinder Slave X
grinder [Yes/No] Menu available only with
Grinder YES. If one of the two grinders is
out of order or without coffee, all selections
concerning that grinder shall be made NOT
AVAILABLE. The two grinders can operate
either alternately (1st selection grinder 1
– 2nd selection grinder 2 – 3rd selection
grinder 1 - etc...) or completely separated
(as two different drinks). If one of the two
grinders is out of order or without coffee,
all selections will be automatically carried
out with the operating grinder. The wording
Slave X shows the slave number linked to the
MASTER distributor.Managed by WinBianchi
only.
Altern.Grinders Selects the alternate management of the
grinders [Yes/No]. If YES the doses menu
does not change, if NO the entire manage-
ment of the second grinder is added (Coffee
2). With YES if one of the two grinders is out
of order or without coffee, all selections will
be automatically carried out with the ope-
rating grinder. With NO, in the doses menu
the wording Coffee 1 and Coffee 2 will be
managed so to distinguish the two Grinders.
The hardware managing the two grinders will
be a board with a double contact relay so
that, with the double grinder signal, either
the grinder 1 or grinder 2 can be operated.
The exchange of this relay must be carried
out with power off on the grinders. Automatic
grinding will be managed on coffee 1 only.
Cooling Unit Selects the type of cooling unit to be in-
stalled [Yes/No]. With YES it enables the
management of 6 timed outputs and the
management of the compressor from expan-
sion board (see time diagram in the Doses
menu).
Sens. probe min Probe sensitiveness at minimum Level
[20÷200]. Only with Boiler 1 or 2 in Poly-
sulfone. Setting concerning all polysulfone
boilers installed in the battery.
Sens.Probe max Probe sensitiveness- Max level [20÷200]
Only with Boiler 1 or 2 in Polysulfone. Setting
concerning all polysulfone boilers installed in
the battery.
Group 1 Slave X Selects the type of the main boiler group to
be installed [Espresso, Fresh Brew, None]
This menu is available only if boiler 1 is either
Espresso or Instant Polysulfone] The wording
