CONSEQUENCES
CONDITIONS FOR EXIT
OF THE SECURITY
1
SEA
Mains water pressure
sensor/switch
ABSENCE of mains water pressure or tank
empty:
- Check tap or tank
No filling or cycle possible
No heating of coffee
boilers if level sensors,
SNH and SNB are out of
the water
Automatic if fault
eliminated
2
SNH
High level sensor
Disconnected or insufficient level after 60
seconds of filling:
- Check the sensor and the wiring
– Check the filling circuit.
Filling stopped (see
special case of 1st fill)
Automatic if fault
eliminated
3
SNH
SNB
High and low level
sensors
Disconnected or level much too low
- Check the sensors and the wiring
– Check the filling circuit.
Steam boiler heating
stopped - EVE and EVV
outlets closed - Filling
attempt for 60 seconds
- if the level rises as far as
the SNB the heating
restarts
- if the level reaches the
SNH everything becomes
normal again and the EVV
and EVE outlets are again
usable.
Automatically if everything
becomes normal after the
filling attempt.
If not it is necessary to
repair the fault and
perform a machine reset.
4
SNB
Low level sensor
Disconnected or lime scale while the SNH is
in contact with the water (level correct):
- checking the sensor and the wiring
Alarm
Automatic if fault
eliminated
5
SNH
High level sensor
disconnected or insufficient level after 3
minutes of the 1st fill:
- check the sensor and the wiring - Check
the EVR flow
Filling stops
Fault eliminated and
Machine reset
6
TSV
STEAM BOILER
safety thermostat
triggered following overheating:
- Check the STV regulation circuit and the
TSV thermostat (manual reset)
Steam boiler heating
stopped
Fault eliminated and
manual resetting of TSB
and machine reset
7
STV
STEAM BOILER
thermostat / pressure
switch sensor
disconnected, ABSENCE of supply of signal:
- Check the sensor and the wiring
Steam boiler heating
stopped
Fault eliminated and
machine reset
8
STV
STEAM BOILER
thermostat / pressure
switch sensor
short circuit:
- Check the sensor and the wiring
Steam boiler stopped
Fault eliminated and
machine reset performed
9
STV
STEAM BOILER
thermostat / pressure
switch sensor
Reading outside the authorised range:
- Check the programmed value and the
sensor.
Steam boiler stopped
Fault eliminated
10
TS1
Safety thermostat,
GROUP 1
triggered following overheating
- Check the regulation circuit SR1 and the
thermostat TS1 (manual reset)
Heating stopped on Group
1 - Control box BG1 on
stand-by
Fault eliminated and
manual reset of TS1 and
machine reset
11
SR1
Thermostat sensor,
GROUP 1
disconnected, absence of signal:
- Check the sensor and the wiring
Heating stopped on Group
1 - Control box BG1 on
stand-by
Fault eliminated and
machine reset performed
12
SR1
Thermostat sensor,
GROUP 1
short circuit:
- Check the sensor and the wiring
Heating stopped on Group
1 - Control box BG1 on
stand-by
Fault eliminated and
machine reset performed
13
SR1
Thermostat sensor,
GROUP 1
Reading outside the authorised range:
- Check the programmed value and the
sensor.
Heating stopped on Group
1 - Control box BG1 on
stand-by
Automatic if fault
eliminated
