|
|
 |
Configuration Wizard
Within the supporting PC based software,
iTools, are configuration Wizards. These Wizards will guide
|
| you through the configuration process
with interactive help and graphical demonstration of
configuration options. |
QuickStart HMI
Eurotherm have designed a QuickStart HMI Wizard for all of the
3500 Range controllers. In just a couple of minutes the controller
can be ready for use as the wizard leads the user through all of
the basic set-up via the instrument HMI. There is no need for
additional tools, PCs or even an extensive knowledge of control. Informative Displays
All of the 3000 Series displays provide clear messages and data to
ensure operators get the information they need about the plant
conditions. They provide, clear, complete text information with a
custom message facility - (the 3200 uses scrolling text to
maximize clarity for operators) - along with help text for each
controller function. The 3508 and 3504 also have user-defined
displays to offer views onto the process that are best suited to
the operation of the plant. |
|
Easy Recipe Selection
Recipes can be used to change the operating parameters of the
controller or even to change the full configuration - allowing
one basic controller to be easily adapted to many applications.
Recipes can be selected by the controller HMI using an
understandable user defined name, by external hardware
signals, or by digital communications. |
|
|
|
Config adaptor
PC configuration of all 3000 Series can be achieved by using a
configuration adaptor. It gives iTools the ability to communicate
and configure devices without any power being connected. This
device is ideal for distributors and OEMs
who need to stock a wide range of options. |
|
Heater Failure Detection
The 3200 range can accommodate a current transformer input that
can be used to monitor the status of the heaters. Normally used to
provide early indication of a heater fault, this input can also be
used to measure the actual current flowing and indicate the value
on the front HMI, provide alarm output, or make information
available to a supervisory system for power usage calculations. |
|
|
|
Flexible and Creative Solutions |
Graphical Wiring Editor
The 3500 is capable of providing simple solutions to demanding applications. iTools includes a Graphical
Wiring Editor to quickly implement |
| and document such
applications within the controller. This
flexible
tool provides drag and drop wiring and function
block placement to save time in configuration and to
aid with plant diagnostics. |
 |
Specialist Function Blocks
The 3500 supports a comprehensive range of function blocks
to provide solutions with simple configuration.
- Setpoint programmer for time based
profiles - ideal
for furnaces and test chambers

pressure etc
- Maths, logic and timer functions
A System Product
The 3500 is ideal for use in systems with
flexible communication options to suit
the architecture and integrate with
other products. Its functionality
with maths, logic and timers
could also negate the need
for a small PLC - saving
money, time and
space in
the system.
|
|
|
Setpoint
Programming
An impressive Ramp / Soak programmer is
available in the 3500. The ability to store up to 50
different programs, each with dual channel capability makes
its ideal for applications such as heat treatment furnaces,
autoclaves and environmental chambers - where often more
than one variable needs to be Profiled. |
|
The 3500 has functionality not normally found in a product of this class and its flexibility in being able to interact with other function blocks makes it a very powerful device.
Infrared clip
Communications to the 3500 can be achieved by using
an infrared communications adaptor. Clipping onto
the front fascia of the controller this device
allows configuration and commissioning to be
performed without the need to access the rear
terminals of the controller |
 |
I/O expander
The I/O expander provides increased
programmer functionality by
increasing the digital I/O
capability and expands the
3500 logic capacity by up
to 40 I/O.

Products designed to integrate |
System Integration
Designed to integrate seamlessly with programmable logic
controllers and other supervisory control and monitoring systems
the 3000 Series provides a unique level of system integration. By devolving loop control to a 3000 Series controller a PLC is
able to concentrate on providing fast and effective logic control
without the burden of running complex control algorithms. The
3000 Series controllers also offer better control performance
than a PLC, the comfort of single loop integrity and ease of
replacement without stopping the process. A wide range of communication options are catered for by simply
plugging in the appropriate module. All units support both RS232
and 2-wire RS485 communicating using the Modbus™ RTU
network protocol. Additionally the 3508 and 3504 support 4-wire
RS485 and Profibus™ DP network, DevicNet™ and Modbus TCP
network protocols. |
|
Serial Communications
Utilizing one of the most common protocols used within the
Industrial Automation market, the Eurotherm implementation of
Modbus RTU is based on a fixed address table. Parameter
addresses are fixed and do not move depending on how the unit
is configured making communication to intelligent masters very
easy to accomplish. Modbus Master
The 3500 provides the facility to broadcast one parameter using
Modbus RTU to a number of slave units. Typically this would be
used to retransmit a Setpoint to other slave zones within a furnace. |
|
|
|
A powerful system tool |
Fieldbus Networks
Profibus and DeviceNet are used extensively to communicate to
Siemens and Allen Bradley programmable logic controllers. The 3500 range can easily be integrated in machines where loop
controllers are required to act as slaves to a PLC. Using a PC editor the Profibus GSD file required for the PLC can
quickly be created by simply selecting parameters from
a pick list. When using DeviceNet the 3500 EDS file can be registered and
the parameter input and output tables edited using Allen
Bradley’s RSNetWorx™ configuration tools. |
|
Ethernet Connectivity
Utilising the popular Modbus TCP network protocol the 3500
controllers can be connected to an Ethernet network. This
enables plug and play connection to other Eurotherm products
such as graphic recorders and third party PLCs or SCADA. |
 |
|
|
| Real-world applications Whether its for excellence in control, ease of use or
its flexible and creative solutions, the 3000 Series can
be used in many applications to solve problems and
save time and money. |
|
 |
|
|
|
| |
RECIPES
The 3000 recipe function is unique in a controller of this class. Recipes can be stored under a
user-defined name to recall a number of parameter settings. These settings may include
operating variables or configuration parameters, providing a very powerful means of altering the
set up of a controller in a single operation. Recipes may be recalled either from the HMI, over
the communications link, or using digital inputs. |
|
|
TIMER
 The simple timer in the 3200 may be used
to control batch operations, e.g.. food
ovens, sterilizers, fryers. Ideal for any
application requiring a single dwell at the
end of either a controlled ramp or
natural approach to setpoint without the
need for an additional timing device. |
|
|
| |
MESSAGES
The HMI on 3000 Series controllers are customizable to show plant
information in the format that is most useful for the operator.
Customizable scrolling text can indicate event and alarm conditions, to
trigger another function, or instruct an operator of the current state
of the process. The 3500 has additional facilities to enable a user to
design their own user interface. |
|
|
HEATER FAILURE DETECTION
A current transformer input in the 3200 measures the current switched through the load. The measurement is filtered so that the on current and off currents can be separated. From this it is possible to diagnose several load faults including partial load failure, over current and an SSR fault. Typical applications include plastic extrusion, laboratory ovens and other applications where early indication of heater failure can save energy and rework costs.
|
 |
|
PROGRAMMER
Many applications need to vary temperature, or other process values, with time. The setpoint is varied by using a setpoint program. The program is stored as a series of ‘ramp’ and ‘dwell’ segments. All 3000 Series controllers provide this feature. The 3200 has an extremely easy to use 8 segment programmer for simple applications while the 3500 has a very flexible dual channel programmer with storage for 50 programs. The 3500 is ideal for furnace, environmental chamber and autoclave applications that require greater flexibility.
|
|
|
| |
FEEDFORWARD
Feedforward is a control technique used to
compensate for future disturbances or
process changes. It provides an offset on the
controller PID calculation to ensure that
corrective action is taken to prevent the
measured PV being disturbed. A typical
application is additive dosing. By measuring
the flow rate upstream from the dosing pump
it is possible to use the feedforward feature
of the 3500 to achieve an output proportional
to the fluid flow rate. This means that the
dosing rate immediately tracks any changes in
flow rate and so prevents any possibility of
dangerous over dosing. |
|
|
ZIRCONIA
The zirconia block calculates carbon
potential, oxygen concentration and dew
point based on the temperature and probe
mV measurements from a zirconia oxygen
probe. Probe burn-off sequence and
diagnostic alarms are also available to help
extend the life of the probe and predict
impending probe failure while minimizing
downtime and rework. This feature enables
the 3500 to be used to control carbon
potential in an atmosphere furnace, an inert
atmosphere in a sintering furnace and
dewpoint in an endothermic generator. |
|
|
| |
DUAL LOOP
The Dual Loop capability in the 3500 makes it
ideal for controlling interactive processes such
as those found in carburizing furnaces,
environmental chambers, autoclaves and fermenters. All of these applications require
control and often setpoint programming of
two variables. By using the advanced maths
and logic functions within the 3500, intelligent
control strategies can be created to
compensate for interactive effects between
variables and maintain them at setpoint. |
|
DUAL VALVE POSITIONING
The Dual Valve Positioning (VP) feature on
the 3500 allows two motorized valves to be
modulated from one controller. Typically one
valve would actuate a burner or hot air
inlet and the other a cooling damper. This
feature removes the need to interface the
controller via external positioners. The VP
feature can be used with or without a
feedback potentiometer and can also be used
with PID in either control channel to
provide control strategies such as PID
Heat/VP Cool. |
|
MASTER COMMS BROADCAST
 |
In all 3000 Series controllers it is
possible to use the Modbus RTU
communication link to send a value,
(often setpoint) from one controller
to a network of slave devices -
providing the economical creation of
multi-zone temperature control
solutions. |
|
TRANSDUCER SCALING
User calibration can be performed in
all 3000 Series controllers.
The 3200 provides a simple two point
calibration on its input and the 3500 has
a comprehensive set of transducer scaling
options that make it ideal for melt
pressure, load cell or comparison type
calibrations. |
