Figure 1. Dual-Wire Dual-Operator Programmable Monitor

Description

Continuous monitors pay for themselves, by improving quality,
productivity, and eliminating daily wrist strap testing and test
result logging. Per ESD-S1.1 paragraph 6.1.3 Frequency of
Functional Testing, “The wrist strap system should be tested
daily to ensure proper electrical value. Daily testing may be
omitted if constant monitoring is used.”

Per ESD Handbook TR20.20 paragraph 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 Semtronics 62030 Dual-Wire Dual-Operator
Programmable Monitor can maintain two work surfaces and
two operators at ground potential to virtually eliminate the risk
of ESD damage. The highly visible LED display and audible
alarm makes it easy to monitor the status of the work surfaces
and operators. The 62030 Dual-Wire Dual-Operator
Programmable Monitor uses Semtronics patented* dual
resistive loop technology. No other method is as direct and
reliable. Both work surfaces, and individual operator resistance
limits, can be programmed and re-configured as required. If the
ground potential of either work surface or operator is lost the
62030 immediately alarms (both audible and visual). The
62030 is unaffected by capacitance variations associated with
personnel and environmental conditions.

The 62030 Dual-Wire Dual-Operator Programmable Monitor
features:

• Monitoring of two operators independently.

• Monitoring of two ground connections (work surfaces)
independently.

• Fully independent alarming conditions: audible and visual.

• Independent LED status lights for each operator and each
ground connection (work surface.)

• Two independent operator wrist strap ground point remotes
with 10’ cables.

Installation

Remove the monitor from its packaging and inspect for any
shipping damage. Included with each 62030 Dual-Wire Dual­Operator Programmable Monitor should be:

1 Monitor 1 Hardware Kit (62012)
1 White Operator Remote 3 Grounding Wires (SE-5136)
1 Black Operator Remote 1 Mat Ground Cord (Grey)
1 AC Adapter 1 Mat Ground Cord (Black)
4 Push Clinch Snaps

A. Determine the mounting location of the 62030 monitor. The
front panel should be visible to a supervisor.

B. Determine the mounting location of the operator remotes.
The white remote is for operator #1 and the black remote is for
operator #2. Make sure that each remote is located so that the
remote leads reach the monitor but are convenient for the
operator.

C. Attach the operator remotes to the bench or other surface
using the provided screws.

D. Attach the tinned wire ends of the mat wires to the
appropriate screw terminal connection on the rear of the unit.
(See Figure 2). The white wire is for operator #1 and the black
wire is for operator #2.

E. If not already done, attach the work surface to workstation
common point ground using the pictured ground wires. For
mats, attach the grounding point snaps at the ends of the
ground monitor cords to the grounding point snaps on the work
surface. These ground monitor cords are used for sensing
whether or not the unit is properly grounded. Refer to figure 3
for snap-plate fitting diagram and for laminates or other hard
surfaces with a buried conductive layer.

F. Attach the tinned wire end of the black ground-reference
wire to the center position of the screw terminal block on the
rear of the unit. Attach the ring terminal end to an alternate
ground point. It is important that this ground wire is attached to
a separate ground point other than the work surface ground

cords from the previous step to ensure proper independent
monitoring. The faceplate screw of a grounded AC wall outlet
may provide a convenient connection point.

Figure 3. Mat Grounding

G. Route the work surface monitor wires from the back of the
monitor unit, to the snaps/bolts attached to the grounded
surfaces. Attach the white ground wire to the operator #1 work
surface and the black ground wire to the operator #2 work
surface.

H. Route the operator remote wires to the monitoring unit and
insert the modular plugs into the appropriate jacks on the rear
of the unit. (See Figure 2)

Mat Grounding

It is recommended to connect the mat wire (10mm snap) from
the monitor and the mat ground wire (10mm snap) to two
separate points on the bench mat as in Figure 4.

Figure 4. Mat Grounding

I. If using a TR2000 SmartHub along with the 62030, construct

a data output cable. Refer to Figure 5.

J. Plug the DC power supply plug into the power jack in the
rear of the unit. Route the wire from the supply to a nearby
AC outlet and plug the power supply into the outlet. Make sure
the voltage and frequency match those listed on the AC
adapter. The monitor should now be powered.

Operation

Wrist Strap Connections

Once all the connections described above have been made
and the unit has been powered up, the unit is ready for opera­tion. Install operator wrist straps and ground wires. Dual
snaps on the operator ground wires attach to the wristband
snaps and the mono plug on the other end inserts into the
operator remote as illustrated in Figure 6. The operator's
monitoring is in "STANDBY" mode until the operator's ground
wire is plugged into the remote jack for that station.

Figure 6. Operator Ground Cords and Wrist Snaps

NOTE: The operator remote has two jacks. One is a 3.5 mm
mono jack for use with a dual wrist strap. Adual operator
ground wire plugged into this jack will be monitored. The other
jack is a grounded banana jack for use with a single conductor
operator ground wire. This is a grounded guest hook-up that is
not monitored.

Status Indicators

The audible alarm for Operator 1 and Ground 1 is continuous.
The audible alarm for Operator 2 and Ground 2 is a repetitive
beep. If a fault condition exists for both operators and/or both
grounds, the alarm will sound continuously. The alarm volume
may be adjusted with the potentiometer on the rear of the unit.
Refer to Figure 7.
