Alarm Handling
The Mini VII uses computerized sensors to robustly handle Mini VII device malfunctions.
There are two types of alarms the Mini VII can generate:
Blocking Alarms
– these are the most serious. The VII will turn itself Off and display
the alarm codes noted below when one of these alarms occurs.
Non-Blocking Alarms
– These are informational only and, while they do represent an
error condition, the machine will continue to function.
5.1 No Water in Tank
When the tank (4) is out of water the red
EMPTY
light (21) comes on and remains on
until at least 1liter of water is added. The tank can hold up to 3 liters.
5.2
Coffee Group Water Dosing System Failure
When the flow meter isn't working properly or when the coffee grind is too fine, this is
indicated by the turning on of the lights 14-15-16; if you are making one coffee dose,
and the lights 17-18-19 if you are making two coffee doses. This is a non-blocking
alarm. This alarm is actually useful when back flushing as an indication of when to turn
off the pump and allow the 3-way valve to operate.
5.3 Coffee Group Temperature Detection System Failure
This alarm is a blocking one, and occurs when the temperature probe of the group is in
short circuit (temperature >145°C) or is in open circuit (disconnected) condition
(temperature <60°C). The lights 20-21 turn on.
If the group water temperature does not exceed 60°C within 5 minutes of turning the
unit on, this alarm will also occur.
Turn off the Mini V2 and request service.
5.4 Steam Boiler Temperature Detection System Failure
(only with the boiler turned on)
This is a blocking alarm and occurs when the temperature probe of the boiler is in short
circuit (temperature >145°C) or it is in open circuit (disconnected) condition
(temperature <60°C). The lights 19-20-21 turn on.
The alarm can be temporarily cleared by turning the boiler off (Press
BOILER
(26)
button.) Eventually you will need to turn off the Mini V2 and request service.
5.5 Damaged Group Heating Element Triac / SSR
This alarm is a blocking one, and occurs when the group triac always remains in
conduction (temperature >140°C). The lights 20-21 are flashing.
Turn off the Mini V2 and request service. Note: new machines use a dual Solid State
Relay (SSR) rather than the triac.
