TROUBLESHOOTING
In the event that the system is not functioning, follow these
steps
IN ORDER
:
1.
Check that the main power supply is sending the correct
power to the unit.
2.
Power off unit using the Off / On switch. Check the fuse.
If it is blown, replace it with the appropriately sized fast
blow 500 mA glass 5 mm × 20 mm fuse rated at 250 V and
power on. If it fails to power on, continue to the next step.
3.
If the system is controlled by an air pressure switch, and/or
a door switch, check that these are not preventing power
from being sent to the system.
4.
If power is reaching the unit and it was necessary to
replace the fuse, and on powering up, the new fuse blows,
the next step is to determine whether there is a fault in the
system or a tube. First, to check that the system’s power is
functioning, set the ionization power knob and the power
switch both to the ‘off’ position. Make sure all personnel
are clear of the high voltage tubes, then re-connect the
power supply. Flip the power switch to ‘on’ and observe
the green light. If the light does not turn on, there is still a
problem with delivering power to the system. If all external
sources of failure are eliminated, the system should be
serviced by a qualified AtmosAir technician. Please see
contact information at the bottom of this page.
The next step is to determine the cause of the failure, or
blown fuse. Typically, failures are caused by short circuiting
between the inner and outer electrodes, or between
one electrode and ground. This often occurs because of
damaged tubes or dirty and/or wet conditions that have
allowed carbon tracking to temporarily connect two
electrodes and/or a grounding point electrically.
5.
Inspect the mounting plate for tracking evidence.
6.
Inspect the tubes for cracks, pitting, or other degeneration
of the tube material that may cause the tube to become
breached and fail and short circuiting to occur.
7.
If physical inspection has not revealed the cause of
failure, one may carefully observe the tubes as the
ionization system is turned on to determine whether
short circuiting is occurring at a particular tube. The
fuse will usually blow, again, but for a short time, one
may observe the cause of the power surge in the form
of a visual or audio cue. Usually, a failing tube can be
determined in a darkened room by looking for a flash
or arc from the failing tube. In some cases, the correctly
operating tubes may be in the way of the failing tube’s
visual indication.
It is permissible and recommended
to remove the top row of tubes temporarily to assist
in the visual diagnosis. The device uses a bus-bar
technology allowing the servicing technician to
remove any number of tubes needed to diagnose
and/or temporarily run the device whilst waiting for
replacement tubes.
8.
It may be necessary to remove all the tubes to ensure
that the transformer is working properly in the absence
of tubes. If the fuse still blows, then there is an internal
short circuit, and the system should be serviced by a
qualified AtmosAir technician.
9.
It is recommended to also check the voltage levels of
the system when a fuse has blown and been replaced,
in order to ensure that the transformer has not been
irreparably damaged. Output voltage to the tubes are
as follows, Setting 1 = 2,200 VAC, Setting 2 = 2,400 VAC,
Setting 3= 2,600 VAC, Setting 4= 2,800 VAC and Setting
5= 3,000 VAC. If the voltages are lower than expected,
also check that all the connections are secure and rust-
free; also check that the input voltage is approximately
110 VAC or 250 VAC.
10.
If the fuse blows, then the system should be serviced by
a qualified AtmosAir Technician. You can contact repair
services at [email protected] or by contacting us at
1-888-MY-AIR11.
11.
Otherwise, replace the damaged tube(s), clean and
smooth any mounting plate or end cap carbon tracking,
and return the system to service.
