Static Clean Sentinel BTI Owner's manual

Static Control
Sentinel BTI
Benchtop Ionizing Blower
Overview
The Sentinel BTI Benchtop Ionizer utilizes DC high voltage to
generate balanced ionized airflow to eliminate static charges
on surfaces. The unit can be placed at one end of the
workbench, wall or shelf mounted, and directed at the target or
area to be neutralized. The ionizer’s neutralization time will be
optimal at 12” to 48” directly in front of the unit and will increase
as the distance from the unit increases.
General Guidelines
• Keep water, oil, contamination and any fluids away from
the blower at all times
• Keep the unit clean inside and out for optimal
performance
Contents
Remove the ionizer from the carton and inspect for damage.
Included with the unit should be:
• (1) Sentinel BTI Benchtop Ionizer with Stand and
adjustment knobs installed
• (1) Detachable IEC Power cord (US 115V or 230V, UK
or Euro; must be specified at time of order)
• (1) Round foam air filter with (1) ¾” round Velcro hook
dot
• This IOM-Installation, operation, and maintenance
instructions sheet
Installation
Locate the ionizer 1 to 4 feet from the area or target to be
neutralized for optimal performance, making sure that the
airflow will not be restricted. The unit comes with a stand so
that it can be positioned on the work surface, aimed at the
target and locked in via adjustment knobs. It can also be wall
or shelf mounted to keep valuable bench space free for other
purposes and equipment. A working electrical outlet within
reach of the 6’ long detachable cord that is supplied with the
blower will be required. The outlet must be a properly installed
and grounded 3-prong outlet with supplied voltage to match the
blower being installed. If one is not present, consider relocating
the blower to be within reach of an outlet or having an electrical
outlet installed near the blower. Be sure the ON/OFF switch,
located on the front of the unit, is in the “OFF” position. Plug
the power cord into the back of the blower and then into the
appropriate AC power source.
Important Note: Before powering up the unit, verify that the
AC outlet is properly grounded and that the supplied line
voltage matches the electrical spec on the label at the bottom
of the Sentinel BTI blower. Plugging the blower into an outlet
with the incorrect voltage may damage the unit and will void
any warranty coverage. The unit must have a good ground to
maintain proper balance.

Operation
Set the fan speed switch on the front of the unit to the LOW or
HIGH position depending on the operator comfort and desired
decay time. Higher airflow will result in faster static decay
rates. Position the unit so that the maximum airflow is directed
at the items or area to be neutralized. Turn the unit ON.
When the unit is turned on, the “Status” LED will illuminate and
remain GREEN, indicating that the unit 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 second or less. If the unit 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
unit. 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 balance
adjustment pot located on the rear of the unit. 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 unit 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 optimum
neutralization efficiency and operation, cleaning should be
performed on a regular basis, once a month is recommended.
In addition to improving decay time, cleaning also keeps the
ionizer balanced without the need for adjustment.
NOTE: The AC power cord MUST be disconnected before the
unit can be disassembled for maintenance. First, turn the unit
OFF and unplug the power cord. Remove the rear cover by
disengaging the 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 IPA (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 unit.
Use caution when cleaning inside the blower. The emitter
pin electrodes are sharp.
After cleaning the emitter pin electrodes, reattach the rear
cover using the 4 screws. Plug in the power cord and turn the
unit back ON.
A filter has been provided for applications and/or environments
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 3/4" Velcro "hook" dot
(included with the blower) to keep the inside of the blower
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 blower.
Neutralization (Decay) Times
The comparative efficiency of benchtop ionizers is determined
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 unit 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 dangerous
conditions. Servicing should be performed only at the factory,
or by a factory approved technician.
Troubleshooting
The internal state-of-the-art circuitry of the Sentinel BTI Blower
monitors the ion balance of the air exiting the blower,
maintaining optimal offset voltage (balance) to protect ESD
sensitive components and products. If the circuit detects a bias
in the ion balance due to dirty emitter pins or other conditions,
it manipulates the output of the internal DC high voltage power
supplies to compensate for the bias and correct the condition.
When the blower status light is green, the system is functioning
properly and sensing balanced ionization. When the status light
turns amber an audible alarm sounds warning of a "fault"
condition which can usually be resolved easily by the end user.

To troubleshoot a fault condition, follow these steps:
1) turn the switch to "off"
2) remove the power cord from the back of the unit
3) using a small, soft nylon (or similar) bristle brush, lightly
dampened in IPA-isopropyl alcohol (not more than 70%
solution), clean the (8) stainless steel emitter electrode pins,
the fan blades and the internal sensing grill from the back
side of the blower to remove any dirt or dust. A toothbrush
can be used if the back cover is removed from the unit but
power must be disconnected from the unit before opening
up the chassis to prevent an electrical shock hazard. If
available, blow out the unit with compressed air to clean it
out and to dry the alcohol before powering back up.
4) Reconnect to power and turn the unit on.
If the alarm condition persists, adjust the balance of the blower
using the small pot screw accessed through the tiny hole at the
bottom left corner at the back of the blower. This should only
be done by an experienced technician using proper equipment
and procedures as specified in the EOS/ESD-S3.1-1991
Standard. Static Clean Intl., Inc. can calibrate and certify the
blower performance for a nominal fee. If unable to correct a
fault condition, the unit must be returned prepaid to the factory
for evaluation, repair and/or calibration. Contact Static Clean
for an RA-Return Authorization number and ship to address.
IMPORTANT NOTE: In some cases, if the balance-sensing
grill inside the blower becomes contaminated, the blower may
not be able to detect an out-of-balance condition and may
continue to run in a "green light" status. The presence of
contamination on the backside (the side nearest the fan) of the
balance-sensing grill can cause the unit to overcompensate
due to a false reading of the balance. Keeping the unit clean as
recommended in the Maintenance section of this manual will
help insure optimal performance from your Sentinel BTI
Blower. A filter has been provided for applications and/or
environments 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 3/4" Velcro
"hook" dot (included with the blower) to keep the inside of the
blower clean. This filter should be changed every 2 - 4 weeks,
or as needed per a visual inspection.
