which requires correct wiring polarity since the
power pack output is Dc voltage. the LeD will
not illuminate if the wiring polarity is incorrect. the
power pack has two wires to the indicator light, wire
#9 (+), wire #2 (-). the power pack terminals are
identified with the identical numbers. LeD assembly
is with two wires, wire #9 (+) to the red wire, wire #2
(-) to the black wire. VDc measurement with wires
#9 and #2 (to the indicator light) disconnected: 7.9
to 10, with wires #9 and #2 connected 3.8 to 6.0.
Place power in the off position and connect all wires
which have been disconnected before proceeding to the
next section.
Parts should be replaced as required.
STEP 2
CHECK COLLECTOR CELL(S) AND IONIZER(S)
a flashing indicator light is associated with arcing or
high voltage below specifications. if the sound of arcing
is not evident, high voltages are below specifications.
the ionizer(s) and collector cell(s) should be manually
cleaned if the high voltages are below specifications.
refer to Step 3 for measuring high voltages.
the following steps are a process of elimination in
identifying the problems to the ionizer/collector cell
circuits. the power pack connectors are identified as
“ionizer #8” and “collector #7.” all connectors on the
power pack are identified with name and wire number,
with the exception of the ground connector (green wire
to this connection). the wires within the power pack
enclosure are identified with numbers.
(a) Disconnect high voltage wire #8 “ionizer from the
power pack with high voltage wire #7 connected to
the power pack. Place power in the on position.
is the indicator light illuminated? if so, the cell circuit/
components are operational proceed to step (b). if
the indicator light is flashing, perform the following.
Place power in the off position and remove the cells
components. Place power in the on position, is the
indicator light illuminated? if the indicator light is
illuminated, the problem is within the collector cell. if
the indicator light is flashing, the problem is the high
voltage feed through insulator (dirty, cracked, carbon
tracked) and/or the high voltage wire (wire insulation
has deteriorated).
if the indicator light is flashing with the cells
components installed, perform the following:
remove the collector cells and inspect for the following
conditions.
COLLECTOR CELL PROBLEMS WHICH COULD
CAUSE A FLASHING INDICATOR LIGHT
Sometimes removing the collector cell(s) and installing
the collector cell(s) into the unit will clear a flashing
indicator light condition. if not, check the causes below:
• Dirty collector cell(s) (contaminant build up) requiring
manual cleaning.
• “Wet” collector cell(s) not properly dried after a wash
cycle or manual cleaning procedure. use compressed
air to accelerate the drying time.
• Deformed collector cell contact springs contacting a
“grounded surface,” including cabinet high voltage
feed through insulator contact spring.
• Bent cell plate(s) in close proximity to the opposing
cell plate(s).
• Misaligned contact springs between the collector cells
and/or the high voltage feed through insulator.
• Warped cell plates due to:
o improper handling
o High temperature process airstream and/ or
o High temperature hot water utilized for washing
the components (above 180°F (82°C) for both
conditions)
Parts should be replaced as required.
the Bench test Procedure (Section 12) will determine
which components are causing a flashing indicator light.
(b) indicator light is illuminated with the high voltage
wire #7 connected to the collector cell connector
on the power pack. Place power in the off position
and connect high voltage wire #8 to the ionizer
connector on the power pack and place power to the
on position.
is the indicator light illuminated? if so, the ionizer circuit/
components are operational. if not:
• Place power in the off position and remove ionizer
components.
• Place power in the on position.
• Is the indicator light illuminated or flashing?
• If illuminated, the problem is within the ionizer(s).
• If the light is flashing, the problem is the high
voltage feed through insulator (dirty, cracked,
carbon tracking), and/or the high voltage wire (wire
insulation has deteriorated causing a dead short
condition).
the indicator light is flashing with the ionizers
components installed, perform the following:
IONIZER PROBLEMS WHICH COULD CAUSE A
FLASHING INDICATOR LIGHT
Sometimes removing the ionizer(s) and installing
ionizer(s) back into the unit will clear a flashing light
condition. if indicator light is still flashing, check
possible causes below:
• Dirty ionizer(s) (contaminant build up) requiring
manual cleaning.
• “Wet” ionizer(s), not properly dried after a wash cycle
or manual cleaning procedure. use compressed air to
accelerate drying time.
• Deformed ionizer contact springs in close proximity to
a “grounded surface.”
• Misaligned contact springs between the ionizers, or at
the high voltage feed through insulator.
• Cabinet high voltage feed through insulator contact
spring misaligned with the ionizer.
