SmartLog Pro® with Turnstile
Installation, Operation and Maintenance
Description
The EMIT SmartLog Pro® with
Alvarado EDC Waist
High Turnstile
verifies the functionality of an operator’s
wrist strap and footwear, logs the test results, and
controls access to an ESD Protected Area. The turnstile
unlocks after the operator’s wrist strap and/or footwear
is determined to act as a path-to-ground. All operator
test activity is logged into a database to meet the
ANSI/ESD S20.20 requirements for on-going quality
control purposes. Each log entry includes operator
identification, test results, resistance measurements,
time, temperature and humidity.
See
TB-6594
for more information on the patented*
EMIT SmartLog Pro®.
The
Alvarado EDC Waist High Turnstile
features a
rugged industrial grade controller, optical rotation
detection (no mechanical microswitches to break or
continually adjust), and adjustable time out functionality
(turnstile relocks if there is no passage through the
unlocked turnstile). An adjustable dampener slows
and cushions the rotation and self-centers the turnstile
arms to the home position. Stainless steel internal and
external components make the turnstile durable and
easy to maintain.
The turnstile is configured to Fail-Safe Loss-of-Power
Operation. Should loss of power occur, the turnstile’s
arms will unlock and rotate freely in both directions to
allow operators to pass through.

ESD Association Information
“Compliance verification should be performed prior to
each use (daily, shift change, etc.). The accumulation
of insulative materials may increase the foot grounder
system resistance. If foot grounders are worn outside
the ESD protected area testing for functionality
before reentry to the ESD protected area should be
considered.” ESD SP9.2 APPENDIX B - Foot Grounder
Usage Guidance
“Process monitoring (measurements) shall be conducted
in accordance with a Compliance Verification Plan that
identifies the technical requirements to be verified, the
measurements limits and the frequency at which those
verifications shall occur...Compliance verification records
shall be established and maintained to provide evidence
of conformity to the technical requirements.
The test equipment selected shall be capable of
making the measurements defined in the Compliance
Verification Plan.” (ANSI/ESD S20.20) section 7.3
ANSI/ESD S20.20 Table 1 Flooring-Footwear Systems
Technical Requirements Recommended Range “less
than 3.5 x 10
7
ohms measured per ANSI/ESD STM
97.1.”
“Typical test programs recommend that wrist straps that
are used daily should be tested daily. However, if the
products that are being produced are of such value that
knowledge of a continuous, reliable ground is needed,
and then continuous monitoring should be considered or
even required.” (ESD Handbook ESD TR 20.20 section
5.3.2.4.4)
Note: SmartLog Pro® provides wrist strap test per IEC
61340-5-1 Clause A.1 and footwear testing per IEC
61340-5-1 Clause A.2 with upper limits < 3.5 x 10
7
ohms.
