Bench Top Ionizer
Installation, Operation and Maintenance
Description
The Trustat Bench Top Ionizer is a compact (8.5" high
x 6.0" wide x 2.6" deep) ionizer used for neutralizing
electrostatic charges on insulators and ungrounded
conductors in a 12" x 24" coverage area. Its discharge
times (< 2 seconds at 12") and ±25 Volt offset voltage
meet the required limits of ANSI/ESD S20.20 and
ESD TR53. The Trustat Bench Top Ionizer operates
on pulse DC. Pulse DC systems consist of separate
negative and positive ion emitters connected by a pair
of high-voltage cables to their respective high-voltage
power supplies. The two polarities alternately pulse
on and off to limit ion recombination. The ionizer’s one
speed fan (77 CFM) produces consistent performance
within the coverage area. The Trustat Bench Top
Ionizer features a powder coated steel enclosure.

The Trustat Bench Top Ionizer is available in two
models:
Item Voltage
04622 120 VAC
04623* 220 VAC
*Power cords are not packaged with the 04623 ionizer
and must be purchased separately. They are available
as EMIT item numbers 50545 (Europe) and 50546 (UK/
Asia).

Features and Components
A. Power Switch: Toggle the switch up to turn the
ionizer ON. Toggle the switch down to turn the ionizer
OFF.
B. Balance Adjustment: Remove the cap to expose
the balance offset voltage adjustment potentiometer.
Turn the potentiometer clockwise for positive
adjustment. Turn the potentiometer counter-clockwise
for negative adjustment.
C. Rate Adjustment: Remove the cap to expose
the rate adjustment potentiometer. The rate or pulse
frequency can be adjusted down to one pulse per
second or up to 20 pulses per second. Turn the
potentiometer clockwise to increase the rate. Turn the
potentiometer counter-clockwise to decrease the rate.
D. Power LED: Illuminates blue when the ionizer is
powered ON.
E. Pulse Rate LEDs: Illuminates red when positive ions
are emitted and green when negative ions are emitted.
Installation
Place the unit at a desired location where the airflow
will not be restricted. Ensure that the power switch is
set to OFF. Connect the ionizer’s power cord into an
appropriate AC power source.
Operation
1. Position the ionizer so that maximum airflow is
directed towards the items or area to be neutralized.
2. Turn the unit ON. The power LED will illuminate
and remain solid. The pulse rate LEDs will blink
during normal operation.

Maintenance
CLEANING THE EMITTER POINTS
Shifts in offset voltage (balance) are often caused
by particle build-up on the ionizer’s emitter points.
To maintain optimum neutralization efficiency and
operation, cleaning should be performed on a regular
basis.
Use the Desco 60506 Emitter Point Cleaners or a swab
dampened with Isopropyl alcohol to clean the ionizer’s
emitter points.
1. Turn the unit OFF and unplug the power cord.
2. Open the rear screen by loosening the screw and
swinging the grill to one side.
Figure 4. Opening the Trustat Bench Top Ionizers rear
screen in order to access the emitter points
The emitter points should not require replacement
during the life of the unit with normal handling. If
necessary, Desco 60507 Replacement Emitter Points
are available for purchase.
Compliance Verification
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.
Accessories
60509 IONIZER MOTION SENSOR
Desco offers the 60509 Desco Ionizer Motion Sensor as
an accessory for your Trustat Bench Top Ionizer. Use
it to activate your ionizer when an operator is present
and deactivate it when the workstation is vacant. The
Ionizer Motion Sensor conserves energy and reduces
ionizer maintenance.
3. Clean the emitter points using the included Emitter
Point Cleaners or a swab dampened with Isopropyl
alcohol.
4. Reattach the rear screen.
5. Plug in the power cord and turn the unit ON.
6. Verify the performance of the ionizer by using a
charged plate analyzer or ionization test kit.
