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.
Contact Static Clean for service, replacement filters, parts
information and pricing.
