WS Aware Monitor
Installation, Operation and Maintenance
Made in the
United States of America
The WS Aware Monitor is designed with digital signal
processing technology for true continuous monitoring
(versus pulsed or intermittent) of wrist strap functionality
(path-to-ground and presence of 1 megohm resistor)
and operator safety according to accepted industry
standards without capacitance variations from personnel
or environment. Digital signal processing technology
uses dual-wire wrist straps to apply an ultra-low test
voltage of 0.05V onto the operator for the handling of
sensitive components.
The WS Aware Monitor features operator body voltage
detection. It will alarm if the operator generates or
comes in contact with voltage that would be dangerous
to an ESD susceptible item.
Figure 1. SCS 770061 WS Aware Monitor with Standard
Remotes
The WS Aware Monitor continuously monitors two metal
tools for electromagnetic interference (EMI). EMI can
cause equipment lockups and malfunction. The WS
Aware Monitor will alarm if EMI is detected. Each WS
Aware Monitor is calibrated with accepted procedures
and standards traceable to the National Institute of
Standards and Technology (NIST) and includes a
certificate of calibration.
ANSI/ESD S20.20 section 7.3 states “Compliance
verification records shall be established and maintained
to provide evidence of conformity to the technical
requirements.” Per ANSI/ESD S1.1 Annex A.3 Daily
(wrist strap system) testing may be omitted if constant
monitoring used.” Per ESD Handbook ESD TR 20.20
section 5.3.2.4.4 “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.”
The WS Aware Monitor and its accessories are
available as the following item numbers:

Description
The SCS WS Aware Monitor is a dual workstation
continuous monitor for operators, ESD worksurfaces
and metal tools. It continuously monitors the
path-to-ground integrity and body voltage of two
operators, as well as the path-to-ground integrity for two
conductive or dissipative worksurfaces and two metal
tools. It also continuously monitors for electromagnetic
interference (EMI) on two metal tools which may cause
electrical overstress (EOS) damage. The WS Aware
Monitor eliminates the need for periodic testing and
record keeping of wrist straps.

Static Management Program
The SCS 770061 and 770062 WS Aware Monitors
are compatible with SCS Static Management Program
(SMP). SMP continuously monitors your ESD process
control system throughout all stages of manufacturing.
SMP captures data from SCS workstation, equipment
and ESD event continuous monitors and provides a
real-time picture of critical manufacturing processes. All
activity is stored into a database for on-going quality
control purposes. SMP allows you to pinpoint areas
of concern and prevent ESD events. Quantifiable
data allows you to see trends, become more proactive
and prove the efficiency of your ESD process control
system.
SMP is sold separately.

3. Determine the mounting locations of the two
operator remotes. Their jacks should be accessible
to the operators. Locate them within reach of the
included mini-DIN operator remote cables. Use the
operator remotes' mounting tabs to secure them
underneath table tops or equipment.
4. Connect the included mini-DIN operator remote
cables to the operator remote connectors located on
the left-side of the WS Aware Monitor.
5. Route the mini-DIN operator remote cables from the
left-side of the WS Aware Monitor to their respective
operator remotes. Connect the cables to the back
of the operator remotes.
6. Insert the tinned terminations of the mat monitor
cords into the mat 1 and mat 2 terminals located
on the left-side of the WS Aware Monitor. Use a
small screwdriver or probe to push down the orange
spring contacts and open their respective terminal
gates. Insert the tinned wire, and let go of the
spring contact to latch onto the wire. Ensure that
the mat monitor switches are enabled if using these
monitored mat circuits.
7. Route the mat monitor cords from the left-side of the
WS Aware Monitor to their respective worksurface
mats. Use the included push and clinch snaps to
secure the cords to the grounded mats.
8. Insert stripped terminations of tool monitor wires
(not included) into the tool 1 and tool 2 terminals
located on the left-side of the WS Aware Monitor.
25-28 AWG wire may be used. Use a small
screwdriver or probe to push down the orange
spring contacts and open their respective terminal
gates. Insert the tinned wire, and let go of the
spring contact to latch onto the wire. Ensure that
the tool monitor switches are enabled if using these
monitored tool circuits.

A. Visitor Jack:
Insert the dual-wire wrist cord of
a visitor here to connect him/her to ground. This
connection is not monitored, and it can only be used
when the operator jack is occupied. The WS Aware
Monitor will alarm if the visitor jack is used without an
occupied operator jack.
B. Big Brother Sensors:
Detects the presence of an
operator up to 12 inches away and alarms if a wrist
strap is not connected within 4 seconds to prevent
ungrounded handling of ESD susceptible items.
C. Monitored Operator Jack:
Insert the dual-wire wrist
cord of an operator here to monitor his/her body voltage
and connection to ground.
D. WS Aware Monitor Connector:
Use one of the
included mini-DIN operator remote cables to connect the
WS Aware Monitor to this connector.
Installation
Hardware Setup
1. Remove the WS Aware Monitor and its operator
remotes from the carton, and inspect for damage.
2. Determine the mounting location of the WS Aware
Monitor. Its display should be visible to the
operator(s). Use the two 4-40 threaded holes at the
back of its enclosure if desired.

9. Route the tool monitor wires from the left-side of
the WS Aware Monitor to their respective grounded
metal tools, and secure them.
10. Secure one end of the included ground cord to the
ground terminal located on the right-side of the WS
Aware Monitor. Attach the other end of the cord to
a ground point. The face plate screw of a grounded
AC wall outlet may provide a convenient connection
point.
11. Connect an Ethernet cable to the Ethernet jack
located on the right-side of the WS Aware Monitor.
Verify that the cable is properly connected to a
network.
12. Connect the power adapter to the power jack
located on the right-side of the WS Aware Monitor.
Route the wire from the supply to a nearby AC
outlet and plug it into the outlet. Make sure the
voltage and frequency match those listed on the
power supply. The WS Aware Monitor is now
powered.
NOTE: Worksurface must have a conductive layer such
as Dual Layer Rubber or Dissipative 3-Layer Vinyl with
conductive buried layers. SCS workstation monitors are
not recommended for use with homogeneous matting.
