When the temperature lies within the "precleaning w0 -
precleaning activation hysteresis authorisation (w1)"setpoint
range , the air vent closes, the door must be closed (if
previously opened) and the controller will activate the K13
relay (mains water solenoid valve) for w2 minutes, during
which the condenser will be charged with water and filled to
allow the recirculation pump to collect the water needed for
the various cleaning phases.
Ventilation remains active for the whole duration of the phase,
the heating output will keep the set temperature constant.
After the w2 time has elapsed, the machine operation will vary
according to the type of cycle selected: RINSE or CLEANING
cycle.
Phase 2A - RINSE
The selected cycle is performed at the end of the Pre cleaning
phase.
The counting of one w10 minutes cycle starts now: during this
time, the "condenser mains water inflow solenoid valve",
"Direct steam injection" and "water recirculation pump"
outputs will be activated with the ventilation on at maximum
speed.
After the w10 time has elapsed, the machine will go back to
the HOME screen and keep the Water Discharge Pump output
in operation for the time w9 in order to empty the condenser.
If the door is opened or the STOP key pressed, the cycle will
be immediately interrupted and the machine will go back to
the HOME screen.
Phase 2B - Cleaning Preparation
The oven is brought to the cleaning preparation temperature
(parameter w8) with 100% humidification for w11 minutes,
and in the meanwhile the K13 (condenser mains water inflow
solenoid valve) relay will also be activated.
Once the correct temperature is reached, all the outputs
except the ventilation one will de deactivated until the
temperature has fallen below the w18 temperature; then the
regulation, steam injection and mains water injection tasks will
be taken up again. After the w11 time has elapsed, the cycle
will go on to the next phase.
Phase 3B - Cleaning
At the end of the cleaning Preparation phase, the cycle will
launch the cleaning phase.
The cleaning phase sets a w5 time during which the oven is
brought to the cleaning temperature (parameter w3),
ventilation is always active at full speed, the recirculation
pump is started and will pump the hot water from the
condenser into the chamber flooding the detergent tablets.
In this phase there is no steam injection.
After w5, a w6 time is set. The machine disconnects all utilities
(except power) to allow the detergent to act.
The Duty Cycle comprising w5 and w6 will be repeated:
- 3 times if the cleaning cycle is
SOFT;
- 6 times if the cleaning cycle is
MEDIUM;
- 9 times if the cleaning cycle is
HARD;
During the entire cleaning phase, if enabled through the P3
parameter and if the value of the Water Drain probe exceeds
the maximum water drain set point (parameter w19), the
controller will activate the Mains Water Injection output to
allow the condenser temperature to drop.
The differential for this adjustment is fixed and equal to -10°C,
that is to say, water inflow stops when the temperature read
by the Water Drain sensor drops by 10°C as against the
maximum water drain e set point (parameter w19).
At the end of the number of cycles set for the current one, the
machine will go on to the next phase.
Phase 4B - Rinse
This phase has a duration of w13, during which time the
condenser mains water injection, the direct steam injection
and the maximum speed ventilation will be active.
No heating phase and no recycling phase are entailed. After
the w13 time has elapsed, the cycle will go on to the next
phase.
Phase 5B - Drying
The drying phase starts at the end of the rinse cycle.
The machine is brought to the drying temperature (parameter
w14) and with the ventilation on at maximum speed for w15
minutes, after which the cycle ends and the machine goes
back to the HOME screen.
Cleaning cycle stop:
If the cycle is stopped manually during the 1, 2A, 2B or 5B
phases, the machine will stop immediately.
If the cycle is stopped manually during the 3B phase, the
machine will go on to the 4B phase and then will stop at the
end of the 4B phase. If the cycle is stopped manually during
the 4B phase, the cycle will continue with the ongoing phase
and then will stop.
If the door is opened at any time, (from the moment in which
the desired temperature has been attained during phase one
with the closing of the air vent at the end of phase 5), this will
immediately interrupt the cycle and reset the machine to the
HOME screen.
A black-out alarm triggered during any phase will reset the
running phase
