1 Introduction

1.1 Description

Type 703590 is a process and program controller with up to eight controller channels or four program channels. The instrument is built to the format 144 mm × 130 mm for a standard 92 mm × 92 mm panel cut-out and a mounting depth of 170 mm.

The display is a 5" color screen with 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.

A maximum of eight analog inputs and 6 logic inputs are available, 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 comfortable configuration from a PC. Linearizations for the usual transmitter outputs are stored within the instrument, four customer-specific 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.

A serial interface RS422/485 or PROFIBUS-DP can be used to integrate the instrument into a data network.

Modules can be retrofitted quite simply by the user. The electrical connection is made at the back, via plug-in screw terminals.

3 Mounting

3.3 Fitting

h From the back, fit the seal that is supplied onto the instrument. h Insert the instrument from the front into the panel cut-out. h From behind the panel, slide the mounting brackets into the guides on the

sides of the housing. The flat faces of the mounting brackets must lie against the housing.

h Push the mounting brackets up to the back of the panel, and tighten them

evenly with a screwdriver.

3.4 Cleaning the front panel

Cleaning The front panel can be cleaned with normal commercial washing, rinsing and

cleaning agents. It has a limited resistance to organic solvents (e.g. methylated spirits, white spirit, P1, xylol etc.). Do not use high-pressure cleaning equipment.

Page 13

4 Electrical connection

4.1 Installation notes

• The choice of cable, the installation and the electrical connection must conform to the requirements of VDE 0100 “Regulations on the Installation of Power Circuits with Nominal Voltages below 1000 V” or the appropriate local regulations.

• At maximum load, the cables must be heat resistant up to at least 80 °C.

• The electrical connection may only be carried out by qualified personnel.

• The instrument must be disconnected on both poles from the electrical supply if contact with live parts is possible.

• The load must be fused for the maximum relay current, in order to prevent the contacts of the output relay becoming welded in the event of a shortcircuit.

• The user must not replace internal safety devices. The instrument must be returned to the supplier for repair in the event of a fault.

• Electromagnetic compatibility conforms to the standards and regulations cited in the technical data.

vChapter 10.1 “Technical data”

• Run input, output and supply cables separately and not parallel to one another.

• All input and output cables without connection to the mains supply must be arranged as twisted and screened cables. Ground the screen on the instrument side to the potential earth.

• The PE terminal on the instrument must be earthed. This cable must have at least the same conductor cross-section as used for the supply cables. Grounding and earthing leads must be wired in a star configuration to a common earth point that is connected to the protective earth of the electrical supply. Do not loop earth or ground connections, i.e. do not run them from one instrument to another.

• Do not connect any additional loads to the supply terminals of the instrument.

• The instrument is not suitable for use in areas with an explosion hazard (Ex areas).

• In addition to faulty installation, incorrect settings on the controller (setpoint, data of the parameter and configuration levels, internal alterations) can also interfere with the correct operation of dependent processes, or even cause damage. Safety devices should always be provided that are independent of the controller (such as overpressure valves or temperature monitors/limiters) and only capable of adjustment by specialist personnel. Please observe the relevant safety regulations for such matters. Since adaptation (self-optimization) cannot be expected to handle all possible control loops, an unstable parameterization is theoretically possible. The stability of the actual value that is produced should therefore be checked.

Page 14

4 Electrical connection

• Since the instrument is short-circuit proof only to a limited extent, an external fusing and a switch-off facility must be provided. Depending on the supply voltage, the following values apply to the external fusing: AC/DC 20 to 53 V, 48 to 63 Hz fuse 4 A slow (only for operation in SELV or PELV current circuits) AC 110 to 240 V +10/-15 %, 48 to 63 Hz fuse 0.8 A slow

• The measurement inputs of the controller must not exceed a maximum potential of AC 30 V or DC 50 V against PE.

The manual mode can be inhibited.

5.3 Operation: Program controller/generator

If the instrument is configured as a program controller/generator, programs have to be created first, by using the internal program editor or the setup program.

Setpoint limiting for the program channels is performed via the setpoint limitation for the controller channels. There is a fixed 1 to 1 assignment, which is independent of the program setpoint channel that has actually been selected. Example: Setpoint limiting for program channel 2 is always performed via the setpoint limitation of controller channel 2.

General 50 programs with up to 99 segments each can be programmed; a total of 1000

segments can be implemented. Programs are created by programming setpoints and segment times, segment

by segment. Furthermore, the states of the control contacts 1 to 16 and the active

parameter set can be defined for each segment. The setpoint profiles can be output either as a ramp or a step (configurable). v Chapter 7.3 “Generator” (setpoint input) Output as a ramp has been chosen for the following diagrams.

5 Operation

Tol era nce ban d

To monitor the process value, a tolerance band can be applied around the setpoint profile for each segment. If the upper or lower limit is infringed, a tolerance band signal is generated, which is internally processed or produced via an output.

Example: If the process value goes above the set tolerance band, the logic function “Program stop” can be used to hold the program until the process value is within the tolerance band.

for all program channels:

• controller, control contacts and limit comparators are inactive

• the controller setpoints are 0 The system state can be modified via the setup program.

5 Operation

Temporary alterations

Temporary alterations are alterations to the current program in the program editor. They are not stored in the program memory, i.e. alterations will be lost after a fresh start.

In the case of alterations concerning the current segment, the setpoint sequence is automatically adapted.

Curve a: Setpoint progression for alterations in the current segment.

Curve b: Setpoint progression for subsequent segments or repeat cycles.

Alteration of the setpoint during the current segment

If the setpoint is altered at time t

, then

the setpoint curve continues its progression with the setpoint that has been entered. During the residual segment time (=the time remaining to the end of the segment) the setpoint moves to the setpoint for the next segment (Curve a).

Example: alteration of A03 Segment setpoint w03: 10  60

Alteration of the setpoint for the next segment

If the setpoint is altered at time t

, then

the setpoint moves to the entered setpoint for the residual segment time. The slope of the ramp is altered (Curve a).

Example: alteration of A04 Segment setpoint w04: 50 60

Alteration of the segment time for the current segment

If the segment time is altered, then the the setpoint moves to the following setpoint during the residual segment time (Curve a).

If the new segment time is shorter than the segment time that has already elapsed, then the setpoint curve continues from the start of the next segement.

Example: alteration of A03 Segment time: 4h 3h

General The following applies to the representation of parameters and functions at the

configuration level: The parameter is not displayed or cannot be selected if

• the instrument features do not permit the function assigned to the parameter. Example: Output 3 cannot be configured if no output 3 is available in the instrument.

• the parameter is irrelevant to the function that has been configured. Example: Analog input 1 is configured to “Pt100”, which means that display start and end for standard signals cannot be selected.

Access code Factory-set code: 0002

Selectors Selectors are selection menus which fold down when selecting individual

parameters. Two standard selectors are defined for the configuration tables below, for rea-

sons of clarity:

Some parameters are only available for a fixed-setpoint controller (with or without ramp function) or a program controller/generator. For fixedsetpoint controllers, these parameters and settings are marked by a superscript “F” (e.g. ramp

), for program controllers/generators by a “P”.

Customized recalibration

A signal is processed electronically (conversion, linearization …) to produce a measured value via the analog inputs of the controller. This measured value enters into the computations of the controller and can be visualized on the displays (measured value = displayed value).

This fixed relationship can be modified if required, i.e. the position and the slope of the measurement characteristic can be altered.

Page 45

7 Configuration

Procedure Apply two measurement points ((1), (3)), one after another, to the controller;

they should be as far apart as possible. At these measurement points, enter the required display value (start value, end value) in the controller. A reference instrument is most convenient for determining the measured values M1 and M2. Measurement conditions must remain stable during programming.

Programming h Move to measurement point (1)

h Enter start value (2)

h Move to measurement point (3) h Enter end value E (4)

To cancel recalibration, the start and end values have to be programmed to the same value. This automatically sets the start value to 0 and the end value to 1.

Any subsequent recalibration will otherwise be based on the corrected characteristic.

1. If start value=0 or end value=1 is to be set, then the value must first be altered using or

to enable correction.

If recalibration is carried out without a reference instrument, the offset  must be taken into account when moving to measurement point (3).

7.4 Limit comparators

Limit comparators (limit monitors, limit contacts) can be used to monitor an input variable (limit comparator process value) against a fixed limit or another variable (limit comparator setpoint). When a limit is exceeded, a signal can be output or an internal controller function initiated.

16 limit comparators are available.

Absolute At the time of alteration, the limit comparator acts in accordance with its func-

tion.

Relative The limit comparator is in the OFF status.

An alteration of the limit value or the (limit comparator) setpoint could cause the limit comparator to switch ON. Such a reaction will be suppressed, and this condition is maintained until the (limit comparator) process value has moved away from the switch-on region (gray area).

Example: Monitoring the (controller) process value x with function lk4 Setpoint alteration w

b) Condition at the time of the alteration.

The limit comparator remains “OFF” although the process value is within the switch-on region.

c) Stabilized condition

The limit comparator again operates in accordance with its function.

This function also prevents a limit comparator from being triggered during the start-up phase.

7.6 Logic functions

Functions are assigned here to the logic signals of the logic inputs, limit comparators and logic functions (formula).

In addition, the functions for control contacts, tolerance band signal and program end signal are defined for program controllers/generators.

In the case of the fixed-setpoint controller, the ramp end signals can have functions assigned.

Switching action

The functions are arranged in two groups:

Edge-triggered functions

The logic function reacts to switch-on edges. The following functions are edge-triggered:

• Start/stop of self-optimization

• Acknowledgement of limit comparators

• Program start/cancel

•Start timer

• Synchronize clock

• Remote alert

• Segment change

State-triggered functions

The logic function reacts to switch-on or switch-off states.

• All remaining functions

Combined logic functions

The functions are implemented through the combination of up to four control variables.

Any control variable can be selected. The states Z1 to Z4 are assigned to the control variables in descending order of the control variables (see list on the right).

Example: The process value is to be selected via

a logic input and the state of one limit comparator.

This results in the following assignment: Z1 - logic input 1 Z2 - limit comparator 1

If switching between two setpoints or process values only is required, only one logic function has to be configured.

If more than two logic functions are configured to setpoint switching (process value switching), only the first two (see list “Control variable

7.8 C-level control

C-level control is used for the control of carbon in the atmosphere of a gas coking furnace. The C-level is determined through the oxygen measurement with a zirconium dioxide sensor and measurement of the sensor temperature.

C-level control is an extra. Additionally, the math function has to be activated!

C-level calculation

The calculations of the controller are based on the following:

E - e.m.f. of the zirconium dioxide sensor T - sensor temperature in °C P

- partial pressure CO in percentage of volume

- carbon level

Sequence control

Operation using a zirconium dioxide sensor is subject to a fixed time schedule. The sensor has to be “flushed” at regular intervals (cycle time) to ensure faultfree measurement.

During flushing and the subsequent recovery time, the controller is in manual mode. The latest measurement is stored. The average value of the most recent outputs is produced.

During flushing, the output variable logic 1 is “1”. The flushing procedure can be controlled by linking it to an output.

8 Optimization

8.1 Self-optimization

Oscillation method

Self-optimization SO establishes the optimum controller parameters for PID or PI controllers.

Depending on the controller type, the following controller parameters can be defined: Reset time (Tn), derivative time (Tv), proportional band (Xp), cycle time (Cy), filter time constant (dF)

The controller selects one of two procedures (a or b), depending on the size of the control deviation:

Step response method

This type of optimization involves determining the control parameters through an output step that is applied to the process. First a steady output is produced until the process value is “steady” (constant). Afterwards, an output step (step size), which can be defined by the user, is automatically applied to the process. The resulting response of the process value is used to calculate the control parameters.

Self-optimization establishes the optimum control parameters for PID or PI controllers, in accordance with the selected control structure.

Depending on the controller type, the following control parameters can be defined: Reset time (Tn), derivative time (Tv), proportional band (Xp), cycle time (Cy), filter time constant (dF)

Optimization can be started from any system status and can be repeated as often as is required.

The controller outputs (analog, relay, solid-state), the steady output and the step size (min. 10%) have to be defined.

Principal applications of the step response method:

- Optimization instantly after “power on”, during the start-up phase Considerable time savings, setting: steady output = 0 %.

- The process does not readily permit oscillations (e.g. highly insulated furnaces with small losses, long oscillation period)

- Process value must not exceed setpoint If the output (with stabilized setpoint) is known, an overshoot can be avoided through the following adjustment: steady output + step size <= output in stabilized condition

a) SO in start-up phase

b) SO at setpoint

Start of SO

Switching line

Page 76

8 Optimization

Start of self-optimization after power-on and during the start-up phase

With output type “solid-state”, the cycle time during optimization is reduced to 8 x the sampling time.

With the “relay” output type, care has to be taken that the process value is not influenced by the switching cycle time, since otherwise optimization cannot be completed successfully.

Solution: Reduce the cycle time Cy, until the process value is no longer influenced. (Manual mode can be used for the adjustment!)

h Switch the “Status” parameter at the operating level to “inactive” or press

again

8.2 Check of the optimization

The optimum adaptation of the controller to the process can be checked by recording the start-up phase with the control loop closed. The diagrams below indicate possible maladjustments and how these can be corrected.

The control response of a third-order control loop of a PID controller is shown as an example. However, the procedure for adjusting the controller parameters can also be applied to other control loops.

9 Retrofitting of modules

The following steps are necessary for retrofitting modules:

Safety notes

Identifying the module

h Identify the module by the Sales. No. affixed to the packaging

Only qualified personnel are permitted to retrofit modules.

For safety reasons, care must be taken that the back panel and the fixing screws are correctly reassembled and mounted after the alterations.

The modules can be damaged by electrostatic discharge. Avoid electrostatic charge during fitting and removal. Carry out retrofitting on a workbench that is earthed.

Modules Code Part no. Board No.

Universal input

Inputa for zirconium dioxide sensor 0 to 2 V

The instrument is fitted from device software version 162.04.01 on with a new type of analog input card. If analog input cards are retrofitted, it must be noted that they cannot be operated together with the older type of card (i.e. do not mix card types). Please note also that an update of the setup program may be required in order to carry out the configuration through the setup program. The device software version (version number) can be read out from the instrument in the “Device info” menu. The nameplate can also be used to determine whether the new analog input modules have been fitted to the instrument (see Chapter 2.3 “Nameplate”).

The boards for the 0/22 V logic output and the supply for a two-wire transmitter are identical, and are detected by the instrument and the setup program as “Logic output 0/22 V”.

9 Retrofitting of modules

Retrofitting of modules

h Remove dummy module or existing module by using a screwdriver, for

example

h Push module into the vacant slot until the pluggable connector snaps into

place

h Hook the back panel into the slots provided on the top edge and close it. h Tighten the screws

Mount screws correctly with shake-proof washers, since they ensure the protective earth (PE) function (tightening torque: 100 — 120 Ncm).
