Reset from Fault condition
16.
This process is useful to discriminate false interpretations of faults caused by electrical shocks or serious
problems on power supply from thermal loop problems.
1.
Serious fault signal occurs with a first phase when the buzzer emits a continuous sound for 20
minutes and blue led flashes, the output FAULT immediately switch (if the generator is
disconnected and connected again you can go directly at point 3)
2.
After 20 minutes, the buzzer stops, while blue led goes on flashing, the FAULT output remains
closed. This phase remains permanently, until the machine is completely disarmed.
3.
When you connect again the machine, blue and red LEDs flash alternately and no sound is emitted.
This phase lasts for 30 minutes, then, the output FAULT is reset and the generator start to work
again. If during this process the generator is disconnected, when you connect it again the time start
again from the beginning and for 30 minutes.
If at the end of this process, the generator start to work again regularly is not necessary any further
operation.
If occurs again the fault condition within the following 20 minutes, it’s necessary a check from the
assistance center, or to send the machine back to the factory.

DEFECT FOUND
POSSIBLE CAUSE
POSSIBLE SOLUTION
When you arm the machine
you hear an internal buzz, like
a motor
The compressor is checking that
there are no obstructions in the
circuit of fog emission
When the machine is armed, for 15
minutes the compressor will monitor the
nozzle. After this time it will deactivate
automatically: if the fogging system is
disarmed, the compressor will go on with
it reaches 15 minutes.
If the machine is disarmed and then armed
again, the count will start again from zero.
When you arm the fogging
system, a little fog flow goes
out from the nozzle even if the
machine has never shot
before
During testing phase in the
factory, we also test the quality
of fog in all produced systems, a
little quantity of the fog liquid
remains in the ducts
This emission occurs just at first activation,
it will decrease visibly with any activation,
until disappearing completely.
After an eventual disassembly and
reinstallation or after the transport of the
machine, with the first activations a little
flow of fog can occur again.
The 3 frontal LED are flashing
and the buzzer emits 1 beep
per minute
The tension on +12 V input is too
low or too high
Check the external power supply or the
alarm unit
The buzzer emits 2 beep per
minute
Low battery but possible shot
Verify/replace battery - See paragraph
MAINTENANCE
The buzzer emits 3 beep per
minute
Low battery but possible shot
Verify/replace battery - See paragraph
MAINTENANCE
The buzzer emits 10
continuous beep per minute
Batteries not present
Insert battery
Connector not inserted correctly
Remove and reinsert the connector
Verify that jumper W5 is inserted
Insert jumper W5
The machine is armed
(BLUE LED ON)
but doesn’t shoot
The front RED LED is on
Bag reset has not been made Reset as
described in paragraph 15
Bag is in reserve or empty-Change the bag
as described in paragraph 15
The front GREEN LED flashes
The heat exchanger has not yet reached
the minimum temperature of shooting,
wait for the led to stop flashing standard
heating time: 60 min.
