Alarm signals
The following table describes the different alarms which may appear.
DISPLAY VISUALISATION
ORIGIN OF ALARM
AL 1 - BLACK OUT
Black-out alarm. When power is cut off under determined conditions
(see
“What
happens if…”
)
AL 2 - FLUE GAS PROBE
Faulty or disconnected flue gas temperature sensor.
AL 3 - HOT TEMP
Flue gas over-temperature. When flue gas temperature is higher than 260°C.
Before displaying the alarm, or when flue gas maximum temperature is
reached (Pr14). the display shows
“HOT FLUE GAS”.
AL 4 - FAULTY INTAKE
Faulty flue gas extractor. When the encoder (tachometer) in the extractor
detects an extractor speed equal to 0.
AL 5 - NO IGNIT ALARM
No ignition. When the flue gas minimum temperature (Pr13) is not reached
within the maximum ignition cycle time (Pr01).
AL 6 - NO PELL. ALARM
Sudden shut-down during the work phase. When, during the work phase, the
flue gas temperature drops below the minimum threshold (Pr13).
AL 7 - THERMAL SAFETY
Temperature safety device. When the safety thermostat (water over
temperature) or fire door micro switch (contact interrupted) cuts in. If the safety
thermostat cuts in the boiler stove must be manually rearmed.
AL 8 - DEPRESS.-FAILURE
Poor depression. When the flue gas pressure switch cuts in (contact
interrupted) due to poor draught in the flue pipe.
AL 9 - WATER PROBE
Faulty or disconnected water temperature probe.
AL c - TRIAC COC
Screw feed TRIAC error. When the screw feed gear motor does not stop for at
least 0.2 seconds during the maximum work interval of 8.0 seconds. Before
the alarm is activated a safety relay cuts in and forcibly cuts off the power
supply to the gear motor.
Every alarm causes the appliance to switch-off immediately. The alarm state is reached after the time set on Pr11
(set as
default at 30”)
and it can be reset by pressing button 4 for a while.
