Installation and use manual for OT-U250PP & OT-U500PP
The machine doesn’t shoot
immediately after arming
For safety reasons and to avoid false fog
emissions during power on, when the
machine is armed, it becomes operative
only after 20’. After this time, the emission
is instantaneous.
Wiring error
Verify that the alarm, once activated has
tension on connectors of at least 12 V
between GND(5) + SHOOTS(4)
BLUE LED is flashing
The buzzer emits a continuous
sound
BLUE and RED LEDS are
flashing alternately
Overvoltage power line
(110/220 V)
Try to reset. See paragraph 17
In case of unsuccessful restore the PCB can
be damaged, contact the assistance
service.
Over temperature of the PCB
Check there is sufficient ventilation around
the machine. See paragraph 17
To reset see paragraph 17
Disturbance/ interference or
potential differences between
devices
In the case of strong interference
(lightning) can occur a thermocouple
reading error, make a reset.
See paragraph 17.
In case of unsuccessful restore can be
occurred a potential difference or a fault.
In large size plants or with more than on
fogging system connected with the same
central, in rare situations, it may occur
that there are potential differences
between the equipment and it could be
necessary to uncouple
Error in the thermal loop
Possible fault of: thermocouple, resistance
or fuse cable. Don’t try to repair
Contact the assistance service center.
Impossible to arm the
machine BLUE LED doesn’t
switch on
Wiring error
Check on the terminal with a tester that
when the alarm system is tuned on there
is a minimum voltage of 11 V between -
GND (5) + ARM (3).
Cannot arm, BLUE LED does
not become on.
Wiring error
Test the terminal that there is a minimum
voltage of between 11V - GND (5) + ARM
(3), when the anti-theft system is activated
When you press the reset
button you don’t hear the
sound of the buzzer, the
frontal LED are flashing but
the RED LED does not reset
The Jumper P3 is in the “SET”
position
Warning in this case shooting
time is reset to zero
Bag reset - Paragraph 15
Shooting time setting - Paragraph 12
Setting the shooting time, the
buzzer does not sound and
the LEDs do not flash
The jumper P3 stands in the
“RESET” position
See the setting mode of the shooting time
at paragraph 13
