INTRODUCTION
1.1 Description
The iSeries Limit Alarm Controller offers unparalleled exibility in process
measurement and alarm applications, accepting 10 different thermocouple types,
18 RTD combinations or 4 process voltage/current inputs and providing 2 relay
alarm outputs and a large multi-color, programmable display. Easily congured
options include 11 different alarm conditions and the unit supports an external
reset input and a buzzer audio annunciator.
Front panel conguration switches allow the user to select the type of input, the
alarm conditions and the resulting display color. Process inputs are fully scalable,
supporting virtually all engineering units with a selectable decimal point providing
a perfect solution for pressure, ow or other process inputs.
Standard features include a built-in 24 Vdc excitation source for transmitters or
other devices and a universal power supply that accepts 90 to 240 Vac. A low
power option is available that supports 24 Vac or 12 to 36 Vdc.

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 device 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
device should be done by qualied personnel. In order to ensure safe
operation, the following instructions should be followed.
This device has no power-on switch. An external switch or circuitbreaker 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 device housing.
• Always disconnect power before changing signal and power
connections.
• Do not use this device on a work bench without its case for
safety reasons.
• Do not operate this device in ammable or explosive atmospheres.
• Unit mounting should allow for adequate ventilation to ensure
device 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 device 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:
The latest Operation Manual is available from the website listed in this
manual.
To Reset the Meter:
When the device is in the “MENU” Mode, push c once to direct device
one step backward of the top menu item.
Push c twice to reset device, prior to resuming “Run” Mode except
after “Alarms”, that will go to the “Run” Mode without resetting the
device.
When using external reset switch: when the device is in the “RUN”
Mode, push d twice to disable all outputs and alarms. It is now in
“STANDBY” Mode.
Push d once more to resume “RUN” Mode.
Push d twice to disable the system during an EMERGENCY.

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.
Use copper conductors
only for power connections
Figure 2.4 Main Power Connections
Table 2.3 Power Connections
FUSE Connector For 115 Vac For 230 Vac DC
FUSE 1 Power* 100 mA(T) 100 mA(T) 100 mA(T)
FUSE 2 Power* 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 to 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 to 240 Vac).
The Safety European Standard EN61010-1 for measurement, control,
and laboratory equipment requires that fuses must be specied based
on IEC127. This standard species 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 signicant 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.

2.3.2 Thermocouple
The gure below shows the wiring hookup for any thermocouple type.
For example, for Type K hookup, connect the yellow wire to the “2” terminal and
the red wire to the “1(-)” terminal.
When conguring your device, select Thermocouple and Thermocouple
Type in the Input Type menu (see Part 3).

Hookup
The two-wire connection is simplest method, but does not compensate for
lead-wire temperature change and often requires calibration to cancel lead-wire
resistance offset.
The three-wire connection works best with RTD leads closely equal in
resistance. The device measures the RTD, plus upper and lower lead drop
voltage and the subtracts twice the measured drop in the lower supply
current lead producing excellent lead-resistance cancellation for balanced
measurements.
The four-wire RTD hookup is applicable to unbalanced lead resistance and
enables the device to measure and subtract the lead voltage, which produces
the best lead-resistance cancellation.
When conguring your device, select RTD type and RTD value in the Input
Type menu (see Part 3).
If the input wires of the meter get disconnected or broken, it will display
+OPN
“Input (+) Open” message except in case of 500/1000 Ω 2-wire
RTD. In this case the display shows
For safety purpose you may want to set up your alarm to be triggered
when input is open. See Alarm 1 & 2 Sections 3.2.6, 3.2.7 for details.

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 RL is 14 kΩ for 10 V process input.

PART 3
OPERATION: Conguration Mode
3.1 Introduction
The device has two different modes of operation.
The rst, Run Mode, is used to display values for the Process Variable,
and to display or clear Peak and Valley values.
The other mode, Menu Conguration Mode, is used to navigate through
the menu options and congure the device.
Part 3 of this manual will explain the Menu Conguration Mode. For your
device to operate properly, the user must rst “program” or congure 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
, and then proceeds to the Run Mode.
