INST6210 – 4/09
Installation / Operation / Maintenance
Sentinel Benchtop Ionizing Blower
Model 6210
Operation
Set the fan speed switch on the front of the Ionizer to the
LOW or HIGH position depending on the operator comfort
or desired decay time. Higher airflow will result in faster
static decay rates. Position the Ionizer so that the maximum
airflow is directed at the items or area to be neutralized.
Turn the Ionizer ON.
When the Ionizer is turned on, the “Status” LED will illumi-
nate and remain GREEN, indicating that the Ionizer is
running normally. The audible alarm may chirp and the
“Status” LED may illuminate AMBER momentarily at
startup but it should return to normal/green mode in one se-
cond or less. If the Ionizer self test circuitry detects a fault
condition, the LED will illuminate and remain AMBER and
an audible alarm will sound.
Refer to the Troubleshooting section of this manual in the
case of a fault condition. There are no user serviceable parts
in this Ionizer. Routine cleaning is the only maintenance
that the user can perform.
Balance Adjustment
The Ionizer is an auto-balancing unit. However, tuning or
manual adjustment can be accomplished by inserting a small
flat screwdriver or trimmer adjustment tool into the tiny hole
for the balance adjustment potentiometer located at the bot-
tom left corner on the back of the Ionizer. To increase the
output of positive ions, turn the potentiometer in a clockwise
direction. Conversely, to increase the output of negative
ions, turn the potentiometer in a counterclockwise direction.
Ideally the Ionizer will produce equal numbers of positive
and negative ions. Use a calibrated Charge Plate Monitor to
verify balanced operation of the Ionizer. Do not attempt
balance adjustment without a Charge Plate Monitor.
Maintenance / Alarms
Under normal conditions, the Ionizer will attract dirt and dust
(especially on the emitter pin electrodes). To maintain op-
timum neutralization efficiency and operation, cleaning
should be performed on a regular basis, once a month is rec-
ommended. In addition to improving decay time, cleaning
also keeps the Ionizer balanced without the need for adjust-
ment.
NOTE:
The AC power cord MUST be disconnected before
the Ionizer can be disassembled for maintenance. First, turn
the Ionizer OFF and unplug the power cord. Remove the
back cover by disengaging the four (4) screws on the back.
The emitter pin electrodes should be cleaned using a Q-Tip
type cotton swab or a soft nylon toothbrush dampened with
isopropyl alcohol. Clean the blades of the fan and the back
of the balance-sensing grill in front of the fan as much as is
accessible from the back of the Ionizer.
Use caution when cleaning inside the Ionizer. The emit-
ter pin electrodes are sharp.
After cleaning the emitter pin electrodes, reattach the back
cover using the four (4) screws. Plug in the power cord and
turn the Ionizer back ON.
A filter has been provided for applications and/or environ-
ments outside of the Cleanroom and Medical Industries. It is
strongly recommended that industrial manufacturing type
users install the filter onto the back grill using the
¾
” round
hook fastener dot (included with the Ionizer) to keep the
inside of the Ionizer clean. This filter should be changed
every 2 – 4 weeks, or as needed per a visual inspection.
Replacement emitter pin electrodes can be ordered from the
factory. Eight (8) emitter pins are required per Ionizer.
Neutralization (Decay) Times
The comparative efficiency of benchtop ionizers is deter-
mined by a standard test published by the ESD Association:
Standard S3.1. Positive and negative decay times (from
1000 volts to 100 volts) are measured in tenths of a second
using this standard. This test was performed with the Ionizer
positioned as shown, with the fan speed on high, and without
a filter. Decay times are as shown.
NOTE:
Unauthorized servicing or modifications to your
Ionizer will void the product warranty and may create dan-
gerous conditions. Servicing should be performed only at
the factory, or by a factory approved technician.
