Fig. 5.2.1-2 The square
ceramic insulator was burnt
and cracked down because
of a long time use of the
wet cell.
Fig. 5.2.1-3 Press the POWER button to
stop the operation and unplug the power
cord. Open the front panel, pull out the
cell before operating. If the CHECK
indicator light does not flash, it means the
cell is damaged.
WARNING
To reduce risk of electric shock always stop the
operation and unplug the power cord from the
electrical outlet before maintenance.
5.2.1 Check the electronic cell
Check if the cell is wet
It is extremely important to dry the cell thoroughly before starting the
unit. If the cell is wet, there will be a short circuit in the cell through
the wet ceramic insulators, causing the CHECK indicator light
flashing (See page 5-7). Further more, if the cell has been not
completely dried before using for many times the ceramic insulators
will be cracked down (Fig. 5.2.1-1~2).
Fig. 5.2.1-4 The collector plate is bent, there is a metal wire and a metal plate on the collector plates, causing the
CHECK indicator light flashing.
Fig. 5.2.1-1 When the cell is
wet, the ionizing wires and
positive plates cannot be
insulated from the ground,
causing a short circuit. As long
as a short circuit occurs in the
cell the voltage on the signal
wire will be decreased less than
1.3V dc, leading to the CHECK
indicator light flashing.
Check if the CHECK indicator light still flashes when you
remove the cell from the unit.
If the cell is not wet, try to operate the unit after removing the cell
(Fig. 5.2.1-3).
- Stop the operation and unplug the power cord.
- Open the front panel and take out the cell.
- Close the front panel and start the unit and check if the CHECK
indicator light is still flashing. If it does not flash again, you need to
fix the cell. If the CHECK indicator light still flashes, you will have to
go ahead to investigate other causes.
Visually check the cell
Lift the cell in front of a bright light and look through, visually inspect
if there are broken or bent ionizer wires or if the collector plates are
bent or deformed. Broken or bent ionizer wires and bent collector
plates can cause a short to ground, often resulting in visible arcing or
sparking. Any short in the ionizer or collector section lights the
CHECK indicator light. The cell should not be used until the pieces of
broken wire are removed or replaced. The cell can be used
temporarily with one wire missing, although the wire should be
replaced as soon as possible (Fig. 5.2.1-4).
