Fig. 5.2.1-5 Different cell power contact terminals
1-Ionizer terminal
2-Collector terminal
3-Ground terminal
The ionizer wires and positive collector plates are
insulated from the cell frame (Ground) each by the
square and round shape ceramic insulators.
Damaged ceramic insulators can cause a short to
ground, lighting up CHECK indicator light on the
display panel.
Fig. 5.2.1-7 Check the cell with ohmmeter for
short circuit.
Fig. 5.2.1-6 How to check the cell with
ohmmeter for short circuit.
Use an ohmmeter to check the electronic cell for short circuits
On the bottom plate of the cell, there are 3 different power contact terminals.
1-Ionizer terminal: Connecting to ionizer wire latch, providing high voltage of the power supply (See
2.2 ELECTRONIC
CELL ).
2-Collector terminal: Connecting to the positive collector plates, providing low voltage of the power supply.
3-Ground terminal: Connecting to the cell frame and all of the grounded collector plates.
Check the ionizer terminal to
ground, it should show 1
(infinite). If it reads 0.0x, the
ionizer wires are short
circuited and need to be
repaired.
Check the collector terminal
to ground, it should show 1
(infinite). If it reads 0.0x, the
positive collector plates are
short circuited and need
repair.
Check the ground terminal,
it should show 0.0x,
indicating the cell frame is
well grounded.
How to check the cell with ohmmeter
- Set the ohmmeter in the ohm range of 200M (Fig. 5.2.1-6).
- Place the black on the cell frame (Ground) and red each on the ionizer terminal, collector terminal and ground
terminal. It will read 1 or 0.0x. (Fig. 5.2.1-7). See
6.12 REPLACE THE CERAMIC INSULATORS .
