FAULTS AND POSSIBLE SOLUTIONS
FAULT
POSSIBLE CAUSE
POSSIBLE SOLUTION
At power on, you hear a
relay clicking cyclically
It is not a fault
When the machine is still cold or just shot, until it
reaches the working temperature, a relay is activated
together with the triac, in order to lower power
consumption
At power on, you do not
hear a relay clicking
When the electronic board is
powered on, the microprocessor
makes a diagnostic test
During the test, although green leds are flashing, the
heater is not working.
Wait few minutes
Fixed green led
The heater reached the working temperature, so the
relay is not activated, if not occasionally
Green led powered off
No 110/220V power supply, verify there is a tension on
the power connectors and wait few minutes
When the machine gets
armed, you hear a buzz
similar to a spinning
motor
The compressor verifies there is
not any obstruction or sabotage
in the fog emission circuit
The compressor monitors the nozzle for about 15
minutes
After this time, it deactivates automatically.
Even if the machine gets unarmed, the compressor
keeps on working up to 15 minutes.
If the machine is unarmed and then rearmed, time count
starts from zero.
When the machine gets
armed, if never shot, the
nozzle will blow a little
fog
All our machines are tested
during trial phase, thus a little
fog fluid always remain inside
the pipes
This ejection occurs when the machine is put into
operation for the first time and progressively decreases
until it completely disappears.
It can also occur after disassembling, reinstalling or
transport, during the first times the machine is activated.
The buzzer emits 1
bip/minute
The +12 V input voltage is too
low or too high
Check the external power supply or the alarm unit
The buzzer emits 2
bips/minutes
Low battery but can still shoot
Replace batteries – See paragraph 15
The buzzer emits 3
bips/minute
Low battery, can not shoot
Replace batteries – See paragraph 15
The buzzer emits 10
consecutive beeps each
minute
No batteries inside
Insert batteries
False contact battery case
Move the batteries,turn them
Connector not inserted correctly Remove and reinsert the connector
In any case it is useful to use a tester to verify the presence of voltage on the battery case
The machine is armed
(BLUE LED ON)
But does not shoot
The front red LED is on
Reset of cylinders has not been made
Reset as described in paragraph 14
Empty cylinders – Change the cylinders as descrive in
paragraph 14
The front green LED flashes
The heat exchanger has not yet reached minimum
temperature for shooting, waiting for flashing light to
stop (average heating time is 60’)
After arming, the machine does
not accept shooting command
For security reasons and to avoid false fog emissions
at power on, when the machine is armed, it
becomes effectively operating only after 20”. After
this time, the emission is instantaneous.
Wiring error
Verify, once the alarm is on, that there is a tension of 12
V at least between - GND(5) + SHOOTS(4)
