PART 1
INTRODUCTION
1.1 Description
This device can be purchased as monitor (read process value only) or as
a controller.
• The iSeries Strain and Process monitors can measure a wide variety of DC
voltage and current inputs for all common load cells, pressure transducers
and strain gauge type of transducer. The voltage /current inputs are fully
scaleable to virtually all engineering units, with selectable decimal point,
perfect for use with pressure, flow or other process input.
• The iSeries monitor features a large, three color programmable display with
capability to change a color every time when Alarm is triggered. The standard
features include built-in excitation for transducers, selectable as 10V @ 60 mA
or 5 V @ 40 mA. (Built-in excitation is not available with optional isolated
RS-232/485 Serial Communication). Universal power supply accepts 90 to 240.
Low voltage power option accepts 24 Vac or 12 to 36 Vdc.
• Options include programmable RS-232 or RS-485 serial communication and
ethernet with an embedded web server.

1.2 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 not interrupt the Protective Conductor (Earth wire),
and it 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!

1.3 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 and Communication Manual as well as free software
and ActiveX controls are available at the website listed on the cover
page of this manual or on the CD-ROM enclosed with your
shipment.
For first-time users: Refer to the QuickStart Manual for basic operation
and set-up instructions.
If you have the Serial Communications/Ethernet Option you can easily
configure the controller on your computer or on-line.
To Reset the Meter:
When the monitor is in the "MENU" Mode, push conce to direct monitor
one step backward of the top menu item.
Push ctwice to reset monitor, prior to resuming "Run" Mode except
after "Alarms", that will go to the "Run" Mode without resetting the
monitor.

2.3 Electrical Installation
2.3.1 Power Connections
Caution: Do not connect power to your device until you have completed all
input and output connections. Failure to do so may result in injury!
Connect the main power connections as shown in Figure 2.4.
Figure 2.4 Main Power Connections
Table 2.3 Fuse Requirements
FUSE Connector Output Type For 115Vac For 230Vac DC
FUSE 1 Power N/A 100 mA(T) 100 mA(T) 100 mA(T)
FUSE 2 Power N/A N/A N/A 400 mA(T)
For the low voltage power option, in order to maintain the same degree of
protection as the standard high voltage input power units (90 - 240 Vac),
always use a Safety Agency Approved DC or AC source with the same
Overvoltage Category and pollution degree as the standard AC unit
(90 - 240 Vac).
The Safety European Standard EN61010-1 for measurement, control,
and laboratory equipment requires that fuses must be specified based on
IEC127. This standard specifies for a Time-lag fuse, the letter code “T”.
The above recommended fuses are of the type IEC127-2-sheet III. Be
aware that there are significant differences between the requirements
listed in the UL 248-14/CSA 248.14 and the IEC 127 fuse standards. As a
result, no single fuse can carry all approval listings. A 1.0 Amp IEC fuse
is approximately equivalent to a 1.4 Amp UL/CSA fuse. It is advised to
consult the manufacturer’s data sheets for a cross-reference.

RL- Voltage limited resistor, which allows to convert 24 Vdc internal excitation
voltage to the appropriate process input value. For instance: if the potentiometer
value is equal to 10 kΩ, the minimum RLis 14 kΩfor 10 V process input.
When configuring your instrument, select Process Type in the Input Type Menu
(see Part 3).

2.3.4 Strain Gauge
The figure below shows the wiring hookup for 4-wire bridge input.
Figure 2.7
a) 4-Wire Voltage/Bridge Input b) 4-Wire Bridge Input with

Wiring Hookup Hookup
In 4-Wire connections the voltage drop across long excitation lead wires of strain
gauge bridge may cause measurement errors. The output of a strain gauge
bridge also depends on the stability of excitation voltage. To correct for voltage
drop and changes in excitation voltage, 6-wire input configuration and ratio
measurement are used.
In order for the Ratiometric to work properly, the External Excitation should
not drop below 4.6 Vdc.
The figure below shows 6-wire hookup for 6-wire bridge input.

PART 3
OPERATION: CONFIGURATION MODE
3.1 Introduction
The instrument has two different modes of operation. The first, Run Mode, is
used to display values for the Process Variable, and to display or clear Peak
and Valley values. The other mode, Menu Configuration Mode, is used to
navigate through the menu options and configure the controller. Part 3 of this
manual will explain the Menu Configuration Mode. For your instrument to
operate properly, the user must first "program" or configure the menu options.
Turning your Device On for the First Time
The device becomes active as soon as it is connected to a power source. It
has no On or Off switch. The device at first momentarily shows the software
version number, followed by reset RST, and then proceeds to the Run Mode.
For first-time users: Refer to the QuickStart Manual for basic operation
and set-up instructions.
If you have the Serial Communications/Ethernet Option you can easily
configure the controller on your computer or on-line.
