Mounting
Determine the mounting location of the Iron Man
®
Plus
Workstation Monitor. Mount the unit using one of the
following recommended methods:
•
•
Screws
Dual Lock Fastener
Enabling and Disabling Monitoring of Worksurface
Follow the procedure below to disable the monitoring
of the worksurface mat. No jumpers or shunts are
required.
Installation
Placement
Set the Iron Man
®
Plus Workstation Monitor in a clearly
visible, convenient location where it does not interfere
with normal work.
Connecting Reference Ground
Prepare an 18 AWG wire. Strip off the wire insulation
approximately 8mm (1/3" in) at each end of the wire.
Twist the stranded wire on each end. In order to attach
the wire to the Iron Man
®
Plus Workstation Monitor,
insert a small blade screwdriver into the orange slot
above the reference ground connector. Gently push
inward and insert the stripped wire fully into the hole in
the green connector. Release the screwdriver to allow
the wire to catch. Attach the other end of the reference
ground wire to a known-good-ground in the area.
Connecting Mat Worksurface
Prepare an 18 AWG wire. Strip off the wire insulation
approximately 8mm (1/3" in) at each end of the wire.
Twist the stranded wire on each end. In order to attach
the wire to the Iron Man
®
Plus Workstation Monitor,
insert a small blade screwdriver into the orange slot
above the Mat connector. Gently push inward and
insert the stripped wire fully into the hole in the green
connector. Release the screwdriver to allow the wire
to catch. Use the suppliers recommended method to
connect the mat worksurface to the other end of the
wire.
Connecting Cable to Board Under Test
Attach the provided cable with alligator clip to the back
of the Iron Man
®
Plus Workstation Monitor. In order
to attach the wire to the Iron Man
®
, insert a small
blade screwdriver into the orange slot above the Board
connector. Gently push inward and insert the stripped
wire fully into the hole in the green connector. Release
the screwdriver to allow the wire to catch. Attach the
other end of the cable to the targeted PCB using the
alligator clip.
Connecting Power
Plug the power adapter into a power outlet, and plug the
cord into the Iron Man
®
Plus Workstation Monitor.
•
•
•
•
•
•
Unplug the DC input from the device.
Remove or do not insert any wire in the Mat
connector.
Using a thin pin, such as a paper clip, press and
hold the Setup button.
While the button is pressed, plug in the DC input and
then release the Setup button.
Wait for about 30 seconds until the unit recognizes
the absence of a mat. The unit will beep and the Mat
LED will be off.
To re-enable mat monitoring, follow the same
procedure except connect the mat to the Mat input in
step 2.
Selecting Lo or Hi Alarm Level
Follow the procedure below to change the sensitivity
range for overvoltage monitoring. The user should be
grounded by wearing a wrist strap grounding system
before disassembling the Iron Man
®
Plus monitor.
•
•
•
•
•
•
Remove the two screws using Philips screwdriver #1
from the front plate.
Slide the internal board assembly out.
Locate Hi - Lo 3-pin header connector on the main
board.
To select the Lo setting, position the shunt between
the center pin and the Lo pin.
For the Hi setting, position the shunt between the
center pin and the Hi pin.
Slide the printed circuit board back into the housing
and replace front cover screws.

Adjustment of Voltage Alarm Level
Follow the procedure below to adjust the voltage alarm
level of the Iron Man
®
Plus Workstation Monitor.
•
•
•
•
•
•
•
•
•
A DC Variable Power Supply with output of 0 to 50V
Range is required
Adjust DC power supply output to 0 initially.
Plug in AC/DC adapter and power the Iron Man
®
Plus Workstation Monitor.
Turn the monitor voltage Threshold Adjust fully
clockwise using a small screwdriver.
Connect the monitor ground wire to the Common
output of the DC power supply.
Connect the monitor Board wire to the V output of
the DC power supply.
Turn on the DC power supply and set the output to
the required alarm level.
Slowly turn the monitor alarm potentiometer
counterclockwise until the audible alarm and red
LED activates.
Plug in power and resume to normal operation.
Worksurface Ground Resistance Monitor
The Iron Man
®
Plus Workstation Monitor continuously
monitors the resistance between ground and the ESD
worksurface. The dissipative worksurface must be
grounded using the recommended means. The Iron
Man
®
Plus Workstation Monitor does not ground
dissipative surfaces; it only monitors proper grounding of
such surfaces. If the resistance of the conductive path
from such dissipative surface to ground exceeds the
threshold, the alarm will activate. There is a slight delay
in time before the alarm activates.
Voltage on Person Wrist Strap Monitor
The Iron Man
®
Plus Workstation Monitor continuously
monitors the voltage on a person through the dual
conductor wrist strap. The loop resistance is monitored,
which includes the resistance of the operator’s wrist
between the two halves of the wrist band.
Overvoltage Alarm Level
The alarm level can be adjusted for low or high ranges.
This setting is selected by moving an internal jumper
socket inside the unit. The Iron Man
®
Plus Workstation
Monitor will respond to either a positive or negative
voltage. If the voltage is higher than the pre-set level,
a visual red LED and audible alarm are activated. The
alarm will be on for at least 1 second. If the voltage level
is below the preset alarm level, a green LED remains
illuminated. A wire must be attached from the Iron Man
®
Plus monitor to a ground plane of PCB or a fixture to
complete the monitoring system.
PERFORMANCE
Worksurface Ground Resistance Monitor
The alarm level is factory programmed. When the alarm
is activated, the red LED indicates that the ground path
resistance for the worksurface has either increased
beyond preset level or is disconnected.
Person Voltage and Resistance Monitor
The alarm level is monitored when a person is wearing
a dual conductor wrist strap and plugged into the front
jack. The Iron Man
®
Plus Workstation Monitor will
respond to either a positive or negative voltage. There
is a short hold on the body voltage alarm so that it is
not missed. The alarm is also activated when the wrist
strap is worn too loosely and the loop resistance level is
exceeded.
Enabling and Disabling Audible Alarm
The audible alarm can be enabled or disabled by
momentarily pressing a recessed miniature push-button
set switch located on the back of the unit. Use of a small
wire form allows activation of the switch.
Operation
The SCS Iron Man
®
Plus Workstation Monitor can be
used at most workstations with manual assembly and
testing activity. It has the following three functions:
•
•
•
Overvoltage monitor
Mat monitor
Wrist strap monitor
The unit uses green and red LED visual indicators and
an audible alarm.
Printed Circuit Board Overvoltage Monitor
The Iron Man
®
Plus Workstation Monitor continuously
monitors the voltage level between ground and a
printed circuit board (PCB) while in contact with the
ground plane, any grounded part of the PCB or of the
product in process. The Iron Man
®
Plus Monitor uses
a potentiometer located at the back of the unit which
allows adjustment of the voltage alarm level.
When a soldering iron, tweezers, or other type of tool
touches the grounded pad of a board, the Iron Man
®
Plus Monitor will alarm if overvoltage was introduced
onto the PCB. If a soldering iron is not grounded
properly, the components on a PCB can be subjected
to an overvoltage that can cause component damage.
When the voltage (AC or DC) on the PCB exceeds the
preset level, the alarm and red LED activate. If the
operator is not grounded and holding a tweezers to
touch a PCB, the tweezers may also induce a damaging
discharge.
Overvoltage conditions generate an electrostatic
overstress (EOS) or electrostatic discharge (ESD)
event. To prevent this, 1) conductive objects, tools,
and personnel need to be grounded properly, 2) non-
conductive objects must be neutralized by ionization and
remain in a neutral state, and 3) surface materials must
dissipative and connected to ground.

Verification Procedures
The Iron Man
®
Plus Workstation Monitor is calibrated
to standards traceable to NIST. Frequency of
recalibratrion should be based on the critical nature
of those ESD sensitive items handled and the risk of
failure for the ESD protective equipment and materials.
In general, we recommend that calibration be performed
annually.
Use the SCS
CTE701
Workstation Monitor Checker to
perform periodic testing (once every 6-12 months) of the
Iron Man
®
Plus Workstation Monitor. The Workstation
Monitor Checker can be used on the shop floor within a
few minutes virtually eliminating downtime, verifying that
the monitor is operating within tolerances.
