Maintenance
CLEANING THE EMITTER POINTS
Under normal conditions, the ionizer will attract dirt and dust
(especially on the emitter points). To maintain optimum
neutralization efficiency and operation, cleaning should be
performed on a regular basis.
In the event of circuit failure or dirty emitter pins, the
Mini Zero Volt Ionizer 2 will alarm and its status LED will
illuminate orange.
The emitter points should be cleaned using the included
50658 Emitter Point Cleaners or a swab dampened with
Isopropyl alcohol.
1.
Turn the unit OFF by disconnecting its power
adapter.
2. Remove the rear screen by removing the 4 screws.
3. Clean the emitter points using the included 50658
Emitter Point Cleaners or a swab dampened with
Isopropyl alcohol
4. Reattach the rear screen.
5. Reconnect the power adapter to turn on the ionizer.
6. Verify the performance of the ionizer by using a charged
plate monitor or ionization test kit.
The emitter points should not require replacement during
the life of the unit with normal handling. If necessary, item
50668 Replacement Emitter Points are available for order.
Adjustments and Compliance Verification
BALANCE OFFSET VOLTAGE ADJUSTMENT
The Mini Zero Volt Ionizer 2 is an auto-balancing unit.
However, tuning or manual adjustment can be accomplished
by turning the balance adjustment potentiometer located at
the left-side of the unit. To increase the output in a positive
direction, turn the potentiometer clockwise. To increase
the output in a negative direction, turn the potentiometer
counter-clockwise.
Compliance Verification should be per ESD TR53. Offset
voltage (balance) and both polarity’s discharge time should
be checked on every ionizer periodically using an Ionization
Test Kit or a Charged Plate Analyzer. Clean the emitter
points (with electrical power off), adjust offset voltage
(balance) to zero and then re-test for offset voltage (balance)
and discharge times recording the measurements.
