The 3204 includes all the features you have come to
expect from Eurotherm controllers (advanced PID
control, Ramp/Dwell˙ Timer, simple
to use software & menus etc), PLUS 15 scrolling configurable alarm,
warning and/or information messages which can be activated by any parameter.

Safety Message Alerts
Activated by ANY Parameter
|
|
Safety Messaging tell operators what is really
happening; improving safety and process feedback.
|
|
The operator is alerted to alarm priority & exact cause. The message
can even carry instructions on how to respond. Thus not wasting time
waiting for a maintenance officer toadvise that the
problem is non-critical, saving time and increasing productivity!

UNIVERSAL METER
Fast Visual Process Indication
|
|
The 3204 display includes a 7 segment universal meter, for
simple visual indication of process status.
|
|
The meter can be used to display all standard parameters, such as
heat, cool or total power output, process input, signal error, CT Load amps
or setpoint. The meter can also be switched off if required.
|
|

|
"So advanced, it's Simple"
|
|
The 3204 display is useful for semi-skilled operators or
for use in applications where operator process knowledge is limited.
|
|
˙
|
|
The new 3204 1/4th DIN controller provides a new level
of user convenience:
|
|
 ˙˙˙˙˙
A scrolling safety message
delivers plain language messages to let operators and engineers alike know
exactly what is happening to the process.
|
|
˙˙˙˙˙ A Quick Start Wizard makes configuration simpler than
ever. At initial power up the configuration is displayed on the lower display
with clear descriptive text providing scrolling help for each setting.
|
|
˙
|
|
˙˙˙˙˙ Universal inputs enable the simple selection of any
standard thermocouple, 2 or 3 wire Resistance Thermometer or process input. A
custom linearization can be installed using the simple PC tool, iTools.
|
|
˙
|
|
˙˙˙˙˙ A Load Current Transformer (CT) Input provides the ideal
method to monitor load current and provide immediate indication of load
conditions using the built-in graphical display. Partial load failure, heater
open circuit or thyristor short circuit can each be
indicated by clear scrolling operator messages and relay output.
|
|
˙
|
|
˙˙˙˙˙ The Operator Interface is fully configurable enabling any
parameter to be promoted for immediate operator access on level 1 or password
protected level 2. This provides for the simplest solutions right through to sophisticated
applications.

˙˙˙˙˙ The new three color LCD display provides clear
indication of process variables. The upper display shows the process measured
value while the lower display can be set to display a range of parameters
including,˙ setpoint, time remaining and current.

˙˙˙˙˙ Three outputs can be configured to provide any
combination of heating, cooling and alarm.

RAMP / DWELL TIMER
|
|
Included as standard is a multimode ramp/dwell programmer for basic setpoint batching control and more specialised
timing functions. Digital outputs are also provided
for program running and end of timer.
|
|
˙
|
|
SETPOINT PROGRAMMER / PROFILING
|
|
The 3204 Programmer version is a controller which also contains a
four segment setpoint programmer where each segment
consists of a controlled rate ramp to a target setpoint
followed by a dwell at that setpoint. This provides
a low cost solution for applications where basic setpoint
profiling is required. The end of program can be set to dwell, control to setpoint 2 or turn off. Reset, Run and End digital
outputs can also be software wired to relay outputs for alarming and other
control requirments.
|
|
˙
|
|
ZONE CONTROL MASTER / BASIC CASCADE CONTROL
|
|
The master communications feature allows the 3204 to become a master
setpoint programmer, sending its setpoint to slave devices for zone control applications.
Up to 32 slaves can be attached. The same system allows the 3204 to be used
as a basic low cost CASCADE controller for applications where long process
times produce poor control in basic control pplications.

HOT RUNNER CONTROLLER
|
|
HOT RUNNER Controllers are used on injection moulding machines to stop the plastic freezing as it runs
into long narrow channels in the mould. These channels are kept warm by
embedding cartridge heaters into the mould. The cartridges are hydroscopic
(absorb water) and need to be slowly dried out to overcome earth leakage,
shorted turns and overheating. The hot runner (soft start) controller
delivers a reduced power output until a set temperature or time is reached.
The controller then reverts to normal PID control. Phase angle thyristors are often used to control the heaters. The 3204 DC
provides a very economical solution.

CONFIGURATION WIZZARD
|
|
For simplified configuration of messaging and all other
module parameters, a free configuration Wizard is available. This simple Windows based Wizzard uses drop-down selections to guide you through
every parameter quickly and easily, with online help making it even easier to
get the most out of your
controller. Optional configuration clip required for controllers
not fitted with communications.
