The Jumo IMAGO 500 multi-channel program and process controller has 8 controller channels or 4 program channels. The instrument is built to the format 144mm x 130mm for a standard 92mm x 92mm panel cut-out and a mounting depth of 170mm. The display is a 5" color graphics display (27 colors). The layout of the screen templates can be individually adapted and adjusted. Two freely configurable screen templates make it possible to customize the placing of texts, process values, background pictures and icons.

The controller features up to 8 analog inputs and 6 logic inputs, as well as six expansion slots for switched or analog outputs. Four of these slots can be used alternatively for analog inputs or outputs.

A setup program is available for conveniently configuring the instrument from a PC. Linearizations for the usual transducers are stored within the controller, four customerspecific linearization tables can be programmed.

A math and logic module can be used to adapt the instrument to a very wide range of control tasks.

Two serial interfaces, RS422/485 or Profibus-DP, serve to integrate the controller into a data network. Modules can be retrofitted quite simply by the user (see block structure). The electrical connection is made at the rear of the instrument, via plug-in screw terminals.

The operation, configuration and displays are organized into a structural arrangement in the screen templates. The insertion of the (variable) softkey functions in the lower section of the screen keeps the user continually informed about the operating options. The instrument is configured through the well-established level structure (operating, parameter and configuration levels). A customer-specific arrangement of those parameters that frequently have to be altered (user level) can also be implemented by using the setup program.

A wide variety of process values and status displays (e.g. switching states of the limit comparators) are visualized clearly and in detail. Operating states and alarms are indicated by definable texts and icons in a reserved area of the screen. Unused screen templates can be switched out of the display.

The recording function is used to create a graphical representation of the development of process values. This can be used to monitor and check control processes.Features:

  • free choice of signals for 4 analog channels and 3 logic channels
  • memory storage cycle 60 — 3600 measurements per hour
  • ring memory for 43,200 measurements
  • readout of data via the interface

Standard features include self-optimization, making it possible for the controller to be matched to the control loop by a user who is not a control-technology expert. This functions by evaluating the response of the control loop to specific changes in the manipulating variable. Either an oscillatory method or a step response test can be selected. The controller parameters that are calculated are: proportional band, reset time, derivative time, filter time constant, and cycle time.

In a fixed-setpoint controller, the ramp function enables a defined run-up of the process value from t0 until it reaches the given setpoint value. The rate of change is defined as a gradient (°C/min, °C/hour or °C/day). When the setpoint changes, this function is activated in the rising or falling direction. The ramp function can be activated individually for each channel.

In addition to the linearizations for the usual transducers, up to four customer-specific linearizations can be created. The programming is carried out in the setup program, in the form of a table of values or a formula.

Two freely configurable screen templates are available for arrangement into userspecific layouts. Using the accessory setup program, representations of process values and graphics are selected from a library and assembled into the screen template within a graphics editor. Some graphical elements can also be incorporated.

The accessory setup program can be used to define up to 100 texts for use as messages and representations in the screen templates. Furthermore, all instrument texts can be changed or translated into other languages.

Important events, such as alarm messages, external texts or system messages, are collected together in an event list.

Parameters which frequently have to be changed by the user can be collected together and displayed in the screen template "User level" (only through the setup program).

The math module makes it possible to combine values such as setpoints, output levels and measurements into a mathematical formula. The logic module can be used to make a logical combination of such elements as logic inputs and limit comparator states. Up to 16 math or logic formulae can be entered through the setup program, and the results of the calculations can be presented at the outputs or used for internal purposes.

Controllers for difference, ratio, and humidity can be achieved through standard formulae that have been included.

Cascade controller Demanding control tasks can be handled by configuring the instrument as a cascade or trimmer cascade controller. Four cascadecontrollers can be implemented by using eight controller channels.

  • Start/cancel of self-optimization
