Figure 4. Wiring connection instructions for the
monitor control unit.
The following procedure will outline how to correctly wire the
19246
/
19247
monitor control unit to properly monitor an ESD
protected workstation.
1. Use the rear phone jack connections and connect the
Satellite Remote Units to the base unit with the phone cables.
See Figure 4 for wiring connection instructions.
2. Mat monitoring may be bypassed by using the switch
located inside a 1/4" hole at the rear of the satellite.
3. Verify that a ground cord is properly connected to snap
socket on one corner of the ESD worksurface. The other end
of the ground cord is to be attached to the workbench common
point ground. After Satellite Remote Units are mounted, route
wires using a direct route; try to avoid running wires adjacent
to metal.
4. Confirm that worksurface surface resistance is 1 x 10E7
ohms or less. Connect the ring terminal end of the worksurface
cord included with the unit to the screw on the back of the
satellite. Snap the other end to the worksurface grounding
point as shown in Figures 4 and 5.
Screw allows
ground cord to
be bolted to mat;
keeps cord from
disconnecting.

5. A convenient 3-wire 120 VAC outlet should be located and
tested for proper wiring and grounding. We recommend Desco
Item
98130
AC Outlet Analyzer to verify proper wiring.
6. Plug the transformer into the outlet and connect the plug
into the back side of the monitor control unit. The green Work
Surface LED should be lit. The monitor control unit is now
ready for use. If the red Work Surface LED is flashing, check
the snap fastener and ground cords for proper connection.
Installation on Micastat
Materials Needed:
2 Flush Mount Ground Laminate Inserts
1 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 worksurface terminal on
the Satellite Remote Unit 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 satellite remote unit. The satellite remote unit 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 satellite remote unit is installed and is connected to
a grounded ESD protective work surface, the monitor's green
Work Surfaces LED's and its two red Operator LED's should
be on.
The monitor takes 6 seconds to activate its alarm
circuitry when it is first plugged in.
To use the monitor:
1. Plug a wrist strap cord, into either of the Satellite remote
units marked "OPERATOR" on the front of the Satellite
remote unit. This automatically activates the selected operator
channel. The red Operator LED should turn on and the audio
alarm should beep.
2. Remove the charges from your body by making contact
with a properly grounded ESD worksurface. Snap the cord
to the wristband, which should fit snugly on your wrist. This
should silence the alarm 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 wristband and ensure that
it has a secure fit. If you have dry skin use ESD hand lotion
such as Menda Item
35660
When leaving the area a person can take the coil cord along
or unsnap the cord from wristband and attach the socket to
the Satellite remote unit snap that is labeled "Park". This will
de-activate the alarm and allow you to leave the station. If the
cord is plugged into the jack marked "Operator" the monitor will
