HIGH VOLTAGE PROBE MEASUREMENTS
A high voltage probe (refer to manufacturers
instructions) is required to measure high voltage output
from the power pack. the component door should
be closed with unicell(s) installed, the indicator light
illuminated and high voltage wires #8 and #7 connected
to the power pack. refer to figure 3. if the indicator
light is flashing or not illuminated perform SteP 1 and if
required SteP 2 as outlined earlier in this section.
“With Load” is a measurement with high voltage wires
#8 and #7 connected to the power pack and unicell(s)
installed.
1. Place MSH "on".
2. open the lid door to the power pack enclosure and
connect the ground wire from the high voltage probe
to the bare metal surface.
3. Place the tip of the high voltage probe to the ionizer
door feed through insulator bolt. the high voltage
measurement should be 10.0 to 11.8 KVDC.
if the ionizer voltage is below specifications refer step
2, “Ionizer Conditions Causing Failure.” Low ionizer
voltage will decrease the collector cell voltage but
low cell voltage will not affect the ionizer voltage.
4. Place the tip of the high voltage probe to the collector
cell door feed through insulator bolt. the high voltage
measurement should be 5.0 to 7.3 KVDC. If the
collector cell voltage is below specifications refer step
2, “Collector Cell Conditions Causing Failure.”
“no Load” is a measurement of the power pack with
high voltage wires #8 and #7 disconnected from the
power pack.
1. Place MSH "off".
2. Remove the high voltage wires #8 and #7 from
the power pack gently bend high voltage wires to
eliminate the high voltage wires from touching the
power pack connectors.
3. Place MSH "on".
4. Place the tip of the high voltage probe to the ionizer
and to the collector power pack connectors. the high
voltage measurement should be 10.0 to 11.8 KVDC
to the ionizer and 5.0 to 7.3 KVDC to the collector
cell. if high voltage is below specifications to one or
both circuits replace the power pack.
