components
A. Power Cord Connection: Connect the power cord here.
B. Power Switch: Toggle the switch to the left to turn the
ionizer OFF. Toggle the switch to the right to turn the
ionizer ON.
C. Fan Speed Switch: Toggle the switch to the left to set
the fan speed to LOW. Toggle the switch to the middle to
set the fan speed to MEDIUM. Toggle the switch to the
right to set the fan speed to HIGH.
D. Data Input: To be used with the EMIT
Threshold Programmer. See Technical Bulletin TB-6543 for
more information.
E. Data Output: Can be used to connect with other Bench
Top Zero Volt Ionizers. Can be used for data collection.
Contact manufacturer for more information.
F. Balance Adjustment: Turn the potentiometer clockwise
for positive adjustment. Turn the potentiometer
counter-clockwise for negative adjustment.
Installation
Place the unit at a desired location where that the airflow
will not be restricted. Be sure that the ON/OFF switch
located on the rear of the unit is in the OFF position. Plug
the power cord into the unit and then into the appropriate
AC power source.

Maintenance
“All ionization devices will require periodic maintenance for
proper operation.” Maintenance intervals for ionizers vary
widely depending on the type of ionization equipment and
use environment. Critical clean room uses will generally
require more frequent attention. It is important to set-up
a routine schedule for ionizer service. Routine service is
typically required to meet quality audit requirements.” (ESD
Handbook TR 20.20 paragraph 5.3.6.7 Maintenance /
Cleaning)
EIA-625, recommends checking ionizers every 6 months,
but this may not be suitable for many programs particularly
since an out-of-balance may exist for months before it is
checked again. The EMIT Bench Top Zero Volt Ionizer
has a very desirable feature as it will provide visual and
audible alarms when an out of balance exists. ANSI/ESD
S20.20 paragraph 6.1.3.1 Compliance Verification Plan
Requirement states: “Test equipment shall be selected
to make measurements of appropriate properties of the
technical requirements that are incorporated into the ESD
program plan.”
CLEANING THE EMITTER POINTS
Under normal conditions, the ionizer will attract dirt and dust
(especially on the emitter electrodes). To maintain optimum
neutralization efficiency and operation, cleaning should be
performed on a regular basis.
In the event of circuit failure, the unit will enter shutdown
mode.
When the unit enters shutdown mode, ionization will be
stopped, the LED on the front of the unit will illuminate a
constant red, and the audible alarm will continuously sound.
The user must then reset the unit by turning it OFF and
back ON.
The emitter points should be cleaned using the included

the LED will cycle through the colors red, yellow, and
green. The LED will remain green during normal
operation.
