Figure 4 shows the monitor as it is viewed from the rear,
with the work surface wiring in place.
Figure 4. Wiring connection instructions for the 19208.
The following procedure will outline how to correctly wire
the 19208 so as to properly monitor an ESD protected
workstation.
1. Use rear access connections when using monitor with
remote jacks. Access holes are provided on the bottom of
the unit to loosen/tighten connections. See Figure 4 for
wiring connection instructions.
2. Verify that a ground cord is properly connected to snap
socket on one corner of the ESD work surface. The other
end of the ground cord must be attached to a known good
ground point. After remote jacks are mounted, route wires
using a direct route; try to avoid running wires adjacent to
metal, if possible.
3.
Confirm that worksurface surface resistance is 5 x
10
8
ohms or less.
Connect the stripped end of the work
surface cord included with the unit to the terminal marked
“Work Surface” on the back of the unit. Snap the other end
to the worksurface as shown in figures 4 and 5.
Figure 5. Installing cords on the worksurface.
4. A convenient 120 VAC outlet should be located and
tested for proper wiring and grounding. We recommend
Desco Item 98130 AC Outlet Analyzer to verify integrity of
building ground.
5. Plug the transformer into the outlet and connect the mini
plug into the back side of the monitor. The green Work
Surface LED should be lit. The monitor is now ready for
use. If the red Work Surface LED is flashing, check the
snap fasteners and ground cords for proper connection.
Installation on Micastat
®
Laminate
Materials Needed:
2 14244 Flush Mount Ground Laminate Inserts
1 14242 Installation Tool for Flush Mount Insert
1. Install the Flush Mount Inserts first. It is recommended to
install one in the right back corner and the other in the
left back corner of the Micastat
®
laminated bench top.
2. Once both inserts are installed, cut the ground cord
supplied with the monitor into two pieces; make sure that
the tinned end is long enough to connect from the
monitor to one of the flush mount terminals located under
the bench.
3. The remaining wire can then be used to connect the
other flush mount terminal to ground using the supplied
ring terminal. The shrouded molded end can then be cut
off.
When complete, one flush mount terminal will connect the
Micastat
®
laminate to ground, while the other will connect it
to a monitor. The monitor then monitors the ground
connection between the two inserts, and since Micastat
®
is
the only ESD laminate made with a physical uniform ground
layer, it will monitor the entire Micastat
®
surface ground.
The wires will stay under the bench, maximizing the usable
space on the bench top.
Operation
When the 19208 monitor is installed and is connected to a
grounded ESD protective work surface, the monitor’s green
Work Surface LED and its two red Operator LEDs should
be on.
TO USE THE MONITOR:
1. Plug a wrist strap cord, not attached to the wristband,
into either of the monitored jacks on the front of the unit.
This automatically activates the selected operator channel.
The red Operator LED should turn on and the audio alarm
should beep.
2. Snap the cord to the wristband, and slip it on your wrist.
(It should fit snugly.) This should silence the audio and
cause the LEDs to switch from red to green. If this does not
happen, check the coil cord for continuity or damage.
Examine your wrist and ensure that it has a secure fit. If you
have dry skin use antistatic hand lotion such as Desco Item
81080 Reztore™ ESD Hand Lotion.
When leaving the area, a person can take the coil cord
along or leave it attached to the monitor. In either case, the
audio alarm will only sound for about eight seconds.
