Safety Message Alerts
Activated by ANY Parameter
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 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 to advise that the problem is non-critical, saving time and increasing productivity!
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.
The communications option provides full system integration through the industry standard modbus protocol.
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 applications.
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.
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.
