1.1 Safety Considerations
This device is marked with the international caution symbol. It is
important to read this manual before installing or commissioning this
device as it contains important information relating to Safety and EMC
(Electromagnetic Compatibility).
This instrument is a panel mount device protected in accordance with
EN 61010-1:2001, electrical safety requirements for electrical equipment
for measurement, control and laboratory. Installation of this instrument
should be done by qualified personnel. In order to ensure safe
operation, the following instructions should be followed.
This instrument has no power-on switch. An external switch or circuit-
breaker shall be included in the building installation as a disconnecting
device. It shall be marked to indicate this function, and it shall be in
close proximity to the equipment within easy reach of the operator. The
switch or circuit-breaker shall meet the relevant requirements of IEC
947–1 and IEC 947-3 (International Electrotechnical Commission). The
switch shall not be incorporated in the main supply cord.
Furthermore, to provide protection against excessive energy being
drawn from the main supply in case of a fault in the equipment, an
overcurrent protection device shall be installed.
• Do not exceed voltage rating on the label located on the top of the
instrument housing.
• Always disconnect power before changing signal and power
connections.
• Do not use this instrument on a work bench without its case for
safety reasons.
• Do not operate this instrument in flammable or explosive
atmospheres.
• Do not expose this instrument to rain or moisture.
• Unit mounting should allow for adequate ventilation to ensure
instrument does not exceed operating temperature rating.
• Use electrical wires with adequate size to handle mechanical strain
and power requirements. Install without exposing bare wire outside
the connector to minimize electrical shock hazards.
EMC Considerations
• Whenever EMC is an issue, always use shielded cables.
• Never run signal and power wires in the same conduit.
• Use signal wire connections with twisted-pair cables.
• Install Ferrite Bead(s) on signal wires close to the instrument if EMC
problems persist.
Failure to follow all instructions and warnings may result in injury!

1.2 Before You Begin
Inspecting Your Shipment:
Remove the packing slip and verify that you have received everything
listed. Inspect the container and equipment for signs of damage as soon
as you receive the shipment. Note any evidence of rough handling in
transit. Immediately report any damage to the shipping agent. The carrier
will not honor damage claims unless all shipping material is saved for
inspection. After examining and removing the contents, save the packing
material and carton in the event reshipment is necessary.
Customer Service:
If you need assistance, please call the nearest Customer Service
Department, listed in this manual.
Manuals, Software:
The latest Operation Manual as well as free configuration software
(iConnect) are available from the website listed in this manual or on
the CD-ROM enclosed with your shipment.
NO ES, WARNINGS and CAU IONS
Information that is especially important to note is identified by following labels:
NOTE: Provides you with information that is important to successfully
setup and use the Programmable Digital Meter.
CAUTION or WARNIN : Tells you about the risk of electrical shock.
CAUTION, WARNIN or IMPORTANT: Tells you of circumstances
or practices that can effect the instrument’s functionality and must
refer to accompanying documents.
TIP: Provides you helpful hints.

1.3 Description
The wi®Series wireless monitoring and control system features meters compatible
with a large and growing number of wireless sensors: UWTC “Universal
Wireless Thermocouple” Type J, K, T, E, R, S, B, N, and C and UWRTD
“Universal Wireless RTD”. For more information about the UWTC and UWRTD,
refer to the separate manual for these products. The wiSeries 1/8 DIN Panel
Meter & Controller can monitor up to eight (8) wireless sensors.
The Meter connects directly to an Ethernet network and the Internet and features
award-winning embedded Web Server. It is easily configured and monitored with
a Web browser over the Ethernet network or the Internet.
MONITOR AND ALARM: The Meter comes standard with a choice of either two
Form C relays, or two SSR’s (solid state relays) that can be used for control
functions or alarms. The meter can monitor alarm conditions for any or all of the
wireless sensors. For example, the meter can be set up to trip an alarm if any one
of the sensors indicated that it was above or below a pre-set alarm point.
MONITOR & CONTROL LOCALLY AND OVER THE INTERNET: The wiSeries
wireless monitoring and control system provides local monitoring and control, along
with remote Web-based monitoring of temperature from thermocouples and RTD’s.
The wireless sensors transmit up to four hundred feet 400’ (approx. 120 meters--
without obstructions or interference) to a wiSeries meter connected directly to an
Ethernet network and the Internet. The wireless system complies with IEEE
802.15.4 operating at 2.4 GHz.
The wiSeries system let’s you monitor and record temperature over an Ethernet
network or the Internet without any special software--just your Web Browser.
ETHERNET: The wiSeries meter-controller-scanner is an independent node on
the network sending and receiving data in standard TCP/IP packets. It is easily
configured from a Web Browser and can be password protected. From within an
Ethernet LAN or over the Internet, the user simply types the IP address (such as
192.168.1.200) or an easy to remember name (such as "Oven 5" or "Test Fixture")
and the wiSeries meter serves a Web Page with the current readings.
EMAIL ALARM: The wiSeries meter can trigger an alarm if variables go above or
below a Setpoint that you determine. Your alarm can be sent by email to a single
user or to a group distribution list, including text messages to cell phones and
PDA’s. The "Mail Notifier" software is a free and easy program for this application.
CHARTS AND RAPHS: The wiSeries system serves Active Web Pages to
display real time readings and charts of temperature. You can also log data in
standard data formats for use in a spreadsheet or data acquisition program such
as Excel or Visual Basic. We offer a free and easy to use program iLog for logging
data to Excel.
The virtual chart viewed on the web page is a JAVA™ Applet that records a chart
over the LAN or Internet in real time. With the wiSeries system there is no need to
invest time and money learning a proprietary software program to log or chart the
data. Chart scales are fully adjustable on the fly. For example, the chart can
display one minute, one hour, one day, one week, one month or one year.
Temperature can be charted across the full span or within any narrow range such
as (20 to 30°C).

1.3 Description (continued)
DATALO IN : The OPC Server software makes it easy to integrate the wiSeries
wireless sensor system with many popular Data Acquisition and Automation
programs offered by NEWPORT, OMEGA, Wonderware, iConics, Intellution,
Rockwell Automation, and National Instruments, among others.
PRO RAMMABLE COLOR DISPLAY: The wiSeries features patented
programmable color displays. The display can be programmed to change color at
any Setpoint or Alarm point. For example, the meter can be programmed to display
the process value in REEN during warm-up, switching to AMBER to signal the
normal operating range, and in RED to signal an alarm condition. The changes in
color are quickly seen from a distance, and machine operators can intuitively react to
changing conditions. The colors can be programmed to change back when the value
drops back below the alarm point or to "latch" on until being reset by the operator.
The meter can also be programmed to display only one unchanging color: REEN,
AMBER, or RED. This is a useful way to let an operator identify, at a glance,
temperature values in three separate locations, or to display three different
measurements.
The following example Figure 1.1 illustrates how you can hookup the Temperature
Wireless System to your network:
The wireless system consists of a single Meter and one or more End Devices /
Transmitters. The End Devices will send data periodically to the Meter where it serves
as a gateway between the users and the End Devices. The users can access the data
through the Meter’s web server and provided data acquisition software.
A standard web browser can be used to monitor and chart temperature. The browser
can also be used to configure the meter’s IP address, passwords for access and
overall configuration parameters.
