Firmware version 2.03 and 3.03 Edition February 2002

Modifications of firmware versions 2.03 and 3.03

The latest version of the TROVIS 6493 Compact Controller is equipped with an infrared interface. Apart from setting and operating the controller using the operator keys on the front panel, the integrated infrared interface allows you to configure, parameterize and operate the controller using the TROVIS-VIEW Configuration and Operator Interface.

The software for both compact controller versions has been upgraded:

6493-01 Firmware version 2.03

6493-02 Firmware version 3.03.

The measuring range of the reference variable ( WINT, WINT) is adapted automatically to the previously determined measuring range of the controlled variable ( IN1, IN1 or

IN2, IN2). However, changing the measuring range of the reference variable afterwards does not result in an automatic adaption of the measuring range of the controlled variable (see section 3.3.1).

Automatic adaption in the CLAS function (see section 3.2.5): The CLAS function enables you to assign the signals X and WE to the analog inputs IN1 and

IN2. By default, X is assigned to input IN2, WE is assigned to input IN1. If, however, X is assigned to input IN1, WE is automatically assigned to input IN2. So far, WE had to be assigned manually to input IN2.

The parameter Y.PRE has been added to the PAR function. This parameter determines the rate action of the output signal (see section 3.1).

1 Notes

The TROVIS 6493 Compact Controller is a microprocessor-based controller with a flexible software design for the automation of industrial process plants. It is suitable for single control loops as well as for more complex control tasks. The flexible software design allows you to configure control circuits without changing the hardware. The read-only functions can be adapted to your specific plant configuration.

These Mounting and Operating Instructions (EB) describe the powerful features of the compact controller. First, we will explain how to operate the controller conveniently. All functions and parameters are described in section 3. Section 4 provides some practical examples to show you which settings need to be adjusted for the specific cases of application. In sections 6 and 7, the electrical connections and the installation are dealt with. The index at the end of this EB gives you quick and direct reference in case you have specific questions or problems.

EB 6493-1 EN 5

Notes

The controller may only be installed, started up or operated by trained and experienced personnel familiar with the product. According to these mounting and operating instructions, trained personnel refers to individuals who are able to judge the work they are assigned to and recognize possible dangers due to their specialized training, their knowledge and experience as well as their knowledge of the applicable standards.

The controller has been designed for use in electrical power systems. For wiring and maintenance, you are required to observe the relevant safety regulations.

Proper shipping and appropriate storage are assumed.

2 Operation

The TROVIS 6493 Compact Controller can be operated either directly using the keys on the front panel or using the TROVIS-VIEW Configuration and Operator Interface (see section 2.7) for configuration, parameterization and operation.

In the following, we will explain how to operate the controller with the keys on the front panel. First, open the folded back cover of this EB. There is the controller's front panel with its display and six keys. Principally, there are two levels which provide different key functions and different displays: the operating level and the setup level. You may define the functions of the compact controller via configuration and parameterization. A table listing all details required for parameterization and configuration is provided in Appendix A. In addition, we will explain how to configure and parameterize using this table in section 2.6.

2.1 Display

Depending on the selected level, the display shows the following variables and operating states (see folded back cover):

Operation

2.4 Setup level

This level enables you to configure and parameterize the compact controller. You can enter the setup level from the operating level by pressing the enter key once. Here, you may adapt preset functions to your specific needs (configure) and change parameters. The functions are arranged in nine main groups:

PAR (control parameters)

IN (input functions)

SETP (reference variable)

CNTR (control structure and functions)

OUT (output functions)

ALRM (alarm functions)

AUX (additional functions)

TUNE (start-up adaption)

I-O (view process data)

The parameters are always connected to the function they are assigned to. This means that pressing allows you to access only the parameters that are relevant for the

particular function you have chosen. Appendix A lists all functions and parameters provided by the compact controller. The table in-

cludes the main groups and their functions with the setting options in the left column, and the associated parameters in the right column. This table will considerably facilitate learning how to operate the controller. You only have to keep the following in mind:

To move from left to right (in columns), press . To move in the reverse direction (from right to left), use the return key . The key number (KEY) must be entered in setup level only when a function or parameter is

changed for the first time. The right column of the table, i.e. the parameters, can be accessed by pressing the selector key

. Again, press the enter key to move forward in columns. To move in rows from top to bottom, press . To move in reverse direction, press . Confirm new settings or the new value by pressing . An example in section 2.6 illustrates how to configure and parameterize the controller prop-

erly.

Note!

The display changes from setup level to operating level after 5 minutes when no key is pressed!

2.5 Key number

You are prompted to enter the key number when you want to change the settings of functions and parameters.

The compact controller can be operated with or without a key number. Factory default is without key number. Each time you wish to change a function or parameter in the setup level for the first time, you will be prompted to enter the key number. Proceed as follows:

KEY blinks. Enter the key number. Skip the next step for operation without

key number. Note! If the reading on the display looks

like this, the key number can always be changed (see next section).

KEY blinks. Enter the valid key number. In this ex-

ample it is 12.

If you have entered the correct key number, the selected function blinks in the display. If not, you are prompted to enter the key number again with 1 appearing in the upper display section. This means that the controller operates with key number.

Enter the key number again or cancel by pressing the return key .

Changing the key number

You may define a new key number or set up the controller to operate without key number. When defining a new key number, you need to know the service key number which is to be

found on page 104. To prevent misuse, you should cut it out or make it unreadable. Proceed as follows to define a new key number:

You have confirmed the new key number and returned to the selected function or parameter. In our example, we have returned to the Kp value.

2.6 Example for configuration and parameterization

We will use the "Table of functions and parameters" provided in Appendix A for this example. The exercise consists of setting up the controller as a PID controller and adjusting the parameters accordingly.

The biggest problem is of course where to find the appropriate function and what to change in this function. There are two ways to proceed. You may search for the function in the table in Appendix A, which also provides reference to further details. Or you may refer to the index. For the PID controller, you will find the C.PID function which belongs to the main group CNTR. As you already know which main group is to be activated and which function is to changed, proceed as follows:

Press Reading on display Comment

You are in operating level. The display reading will be similar to the

one depicted here.

You have entered the setup level. The display shows the first main group PAR.

Main groups are always displayed in a single line. You are now in the first column of the table in Appendix A.

Note! If you press the enter key again, you get to Kp (see page 14).

repeatedly until CNTR appears on the display.

Browse through the main groups (in the table in Appendix A, you move from top to bottom) until you get to the main group CNTR. Here, you can adjust the dynamic behavior of the controller output.

You have entered the main group CNTR (moved to the right in table). You have reached the functions. Functions are always marked by -CO- for configuration.

The display shows the first function C.PID, "Dynamic behavior of controller output". In our case, the function we were looking for.

You have moved one column further to the right. You now see the current settings of the PI action function. These settings are to be changed to PID action.

KEY blinks

You are prompted to enter the key number (KEY). This prompt is displayed when you change a function for the first time after entering the setup level. You will not be prompted for subsequent changes.

If you do not use a key number, skip the next step.

Use the cursor keys to enter the key number.

In our example it is 27.

Operation

Press Reading on display Comment

The display will look like this if you have entered the key number correctly. If not, you will be prompted again. The upper line blinks, meaning that you may change the settings of the function. In the table, you have moved one column further to the right and have reached "Setting options".

The upper line blinks. Use the cursor keys to select the desired set-

ting. In our example it is Pld for PID action of the controller output.

Confirm changes with the enter key. The upper line stops blinking. The first part of the task is completed.

Now the control parameters KP, TN and TV are to be changed. To do so, enter the parameter level.

Press the selector key to open the parameter level. In the table, you have jumped to the first column on the right page.

C.PID and CP.YP are displayed alternately in the lower display line.

The first parameter Kp is displayed. Note! You can go directly from the PAR dis-

play to this display by pressing the yellow enter key once. You may only change the control parameters KP, TN, TV and Y.PRE.

2.7 TROVIS-VIEW Configuration and Operator Interface

The TROVIS 6493 Compact Controller can be configured, parameterized and operated using SAMSON's TROVIS-VIEW Configuration and Operator Interface via the infrared interface integrated in the front panel.

Operating TROVIS-VIEW is similar to working in Windows Explorer. Apart from configuration, parameterization and operation, TROVIS-VIEW provides additional features to record the compact controller. These are, for example, editing plant texts, saving and printing various configuration and parameterization data, tabulating analog inputs and outputs as well as binary status reports.

The TROVIS-VIEW software with the device-specific module for the TROVIS 6493 Compact Controller is delivered on a CD-ROM (order no. 6661-1031).

For system requirements, refer to the TROVIS-VIEW Data Sheet T 6661 EN or to the readme.txt file in the root directory of the CD-ROM.

Communication between the PC and the compact controller is established via the infrared interface integrated in the controller. The IR interface can be accessed via the controller's front panel. It is located to the left of the yellow enter key (see Fig. 1).

An infrared adapter (order no. 8864-0900) is required to transfer data between the PC's serial RS-232 interface and the controller's integrated infrared interface.

Note!

For additional information on installation, connection and operation, refer to the Mounting and Operating Instructions EB 6493-2 EN.

3 Functions of the compact controller

In this section, all functions of the setup level are described. We assume that you are familiar with the operation of this controller and know how to change functions and parameters.

The compact controller contains nine main groups: PAR, IN, SETP, CNTR, OUT, ALRM, AUX, TUNE and I-O. Each of the sections 3.1 to 3.9 is dedicated to one of the main groups. The main groups have different functions which can be identified by -CO- displayed in the upper display section. The functions are explained in the subsections (e.g. 3.2.1); the subsection titles already indicate the functions' designation. Almost every function provides different setting options from which you can choose one to adapt this function to your specific needs. The setting options of the functions are marked with a small grey square in these instructions. If you need to adjust parameters for your function, they will be specified and explained, if necessary. The value range of the parameters and factory defaults can be found in Appendix A.

3.1 PAR Control parameters

This main group serves a special purpose. In contrast to all other main groups, it does not include any functions. When you open this level, the controller immediately jumps to the parameter level where the control parameters Kp, Tn, Tv and Y.PRE can be set.

This main group allows you to quickly set the control parameters. You may also adjust the same settings in the main group CNTR, with the C.PID function.

3.2 IN Input functions

This main group defines all the functions of the two analog inputs In1 and In2. You may specify the input signal range and assign the analog inputs to the controlled variable X or the external reference variable WE. In addition, you can determine the measuring range of both signals. You may also perform measuring range monitoring. Moreover, the input signal can be filtered or functions may be generated from it.

3.2.3 MEAS Measuring range monitoring for analog input 1 and 2

This function enables you to define whether the measuring ranges of the analog inputs are to be monitored either for exceeding or falling below the measuring range.

Choose between :

oFF ME.MO No measuring range monitoring

In1 ME.MO Measuring range monitoring of analog input IN1

In2 ME.MO Measuring range monitoring of analog input IN

ALL ME.MO Measuring range monitoring of both analog inputs IN1 and IN2

When values exceed or fall below the measuring range, this is signalized on the display by the alarm message icon . The binary output is set for alarm messages. In addition, "__o1" blinks in the upper display section when values exceed the measuring range, "__u1" blinks when values fall below the measuring range of analog input 1, or of the analog inputs 1 and 2. When analog input 2 exceeds or falls below the measuring range, " __o2" or "__u2" appears on the display. Whenever values exceed or fall below the measuring range, the compact controller can change to manual mode (see section 3.2.4).

3.2.4 MAN Changeover to manual mode upon transmitter failure

This function enables you to define whether the controller switches to manual mode, and which output value is generated when the measuring range is exceeded or not reached. This function only becomes effective when measuring range monitoring has previously been activated in the MEAS function (see previous section 3.2.3). Manual mode is easily recognizable by on the display.

When values exceed or fall below the measuring range, Y1K1 only becomes effective when the compact controller is in automatic mode.

The parameter Y1K1 can also be set in the main group OUT via the SAFE function as well as in the main group AUX via the RE.CO function (see sections 3.5.1 and 3.7.1).

3.2.5 CLAS Assignment of X and WE

Internally, the compact controller operates with the analog input signals X and WE. The CLAS function is used to assign these signals to the analog inputs IN1 or IN2. By default, X is assigned to analog input IN2 and WE to analog input IN1.

3.2.6 DI.FI Filtering of input variable X and WE

This function enables you to determine whether X and/or WE are to be filtered. The first-order filter (low-pass filter or Pt1 behavior) smooths the selected signals and suppresses

input signal interferences of higher frequency. The time constant of the Pt1 element is defined by the parameter TS.X for the input signal X, and

by TS.WE for the input signal WE. The time constant is given in seconds.

EB 6493-1 EN 23

Functions of the compact controller

Function generation means that a signal is re-evaluated to be further processed. This allows you to adapt auxiliary, reference or equivalent variables required for measuring and control to your specific control loop. For this purpose, you must specify 7 points to characterize the relationship between signal E to be function-generated (X or WE) and the desired new output signal E' (X' or WE'). This relationship should be known to you either from physical laws, experience or from calculated

values (e.g. the relationship between steam pressure and temperature). We recommend that you either draw up a table or create a curve in a Cartesian coordinate system. Choose the 7 points in such a way that a curve can easily be created by drawing straight lines between two adjacent points.

The points are entered via the parameters K1.X to K7.X for the input signal, and K1.Y to K7.Y for the output signal. The values are entered as absolute values, i.e. in units of measurement comprehensible to the user (e.g. in °C, bar or %).

Even when the signal curve can be sufficiently characterized by less points, 7 points must be specified. If applicable, they can be defined in the same position as the last point.

The parameters MIN and MAX are used to determine the measuring range of the output signal E'. It corresponds to that of signal E (not function-generated) with reference to the output signal E'. By entering these two parameters, a proper basis for the percentage calculation performed by the software is created.

If K1.Y or K7.Y do not agree with MIN and MAX, the output values for the function-generated signal, which are below or above these limits, are constantly set to K1. Y or K7.Y. In doing so, the compact controller completes the polygonal curve by generating straight lines (see Fig. 3).

If you have entered an output value greater than MAX or smaller than MIN, it will be set to the value of MAX or MIN.

You will find an application example for function generation in section 4.3.

3.3 SETP Reference variable

This main group enables you to determine one or more reference variables, and you can switch between them as required. The compact controller has two internal reference variables W and W2 for fixed set point control. However, you must activate W2 to use it. The default setting of the controller is fixed set point control. To obtain follow-up control, you only need to activate the external reference variable WE. However, the input WE can also be used for fixed set point control, serving as an input for the position transmission of a three-step output with external position feedback, or as feedforward control. If you want to activate one of these control modes, you need to adjust them in this main group. Moreover, you may select a set point ramp with various starting conditions.

This function enables you to define which reference variables are active: W, W2 and/or WE. When you activate WE, follow-up control will automatically be effective, unless you use WE as input for the position transmission of a three-step output with external position feedback (F01 WE), or for feedforward control (F02 WE).

Parameter level allows you to define the desired value of the reference variable (W, W2) and its measuring range ( WINT, WINT). This range must be identical to the measuring range of the controlled variable ( IN1, IN1 or IN2, IN2). You may limit this measuring range with the parameters WRAN and WRAN. The value of the reference variable can only be chosen between WRAN and WRAN. This also applies in operating level.

3.3.2 SP.FU

This function enables you to define a set point ramp and change between the different reference variables via the binary input.

Set point ramp means that the

reference variable changes at

a constant rate. When the ref-

erence variable is changed,

the compact controller follows

this change with a certain de-

lay to prevent oscillations. The

transit time of the set point

ramp is determined by the pa-

rameter TSRW. TSRW refers

to the entire defined measur-

ing range, e.g. WINT and

WINT. When the reference variable changes from a value W

to a new value W2, the actual transit time of the set point ramp is the time t

, as il-

lustrated in Fig. 5. You may start the set point

ramp via the binary input, and

choose between two starting values (actual value or parameter WIRA). The set point ramp can also be active upon each change of the reference variable.

Note!

Several functions may be assigned to the binary input!

3.4 CNTR Controller structure and functions

This main group enables you to determine the functions for the control algorithm. You may define the dynamic behavior of the controller output, the operating direction of the error and the output variable. In addition, you may select the input variable for the D element and set a control mode changeover. If you use the input WE for feedforward control, you may link this signal to parameters. Optionally, the binary input can be used to influence the actual value. Finally, you may define an operating point in manual mode, which is then added to the calculated operating point in automatic mode.

3.4.1 C.PID Dynamic behavior of controller output

This function enables you to define a dynamic behavior for the compact controller according to the control algorithm. Factory default is PI action. You can also set the control parameters. Moreover, you may define the dead band DZXD for the error; the control signal does not change within this band. In addition, you can determine limits for the error using the parameters DZXD and DZXD. These minimum or maximum values of error are used for output signal calculation.

3.4.2 SIGN Inversion of error Xd

This function enables you to reverse the input operating direction. Multiplication by –1 converts an increasing error into a decreasing one, or vice versa, a decreasing error into an increasing one. This also inverts the operating direction of the output signal. Note the set operating direction in the DIRE function (see section 3.4.6)! There, the operating direction of the output signals may be changed as well.

3.4.3 D.PID Assignment of controller output D element

When dynamic behavior with D component has been selected (see section 3.4.1), you may set different input variables for the D element: error or controlled variable.

If you have selected error, the compact controller reacts to a fast change in the controlled variable, the reference variable or the disturbance variable by generating a D-step response.

If you select the controlled variable, only a fast change in the controlled variable causes a D-step response in the output variable. The D component of the compact controller does not consider changes in the disturbance or the reference variable.

3.4.4 CH.CA Control mode changeover P(D)/PI(D) control

Control mode changeover enables the compact controller to be operated under varying operat-

ing conditions with different dynamic behaviors according to the control algorithm. Generally, control mode changeover is only useful when a control action with I component has been selected (see section

3.4.1). The control mode changeover

function activates either P (or PD) or PI (or PID) control depending on the error or reference variable.

Beyond the definable range of

the reference variable or error, the parameters for P or PD control are used to operate the controller. Within this definable range, the I component is included. The range is defined by the parameters CLI.P and CLI.M, as illustrated in Fig. 7.

Special feature of F01 CC.P setting:

If the controller changes from manual to automatic mode while the error is outside the defined range, the operating point is determined by the last manual output value. The operating point applies until the error returns to the range. The operating point of PI(D) action is determined there. If the error moves outside the range again, the last output value is set as the operating point. If the controller changes from automatic to manual mode, the operating point required for the plant must be reset again before returning to the automatic mode. The operating point is only saved temporarily (Y.PRE parameter does not have any effect). After power failure, the operating point must be reset in manual mode.

Choose between:

oFF CC.P No control mode changeover

F01 CC.P Control mode changeover activated by error

PID

This function enables you to activate operating point adjustment in manual mode. In the factory defaults, this option is deactivated. To activate the operating point adjustment proceed as follows: in manual mode, adjust the output variable using the cursor keys to the desired value. When switching to automatic mode, the last value received is stored as operating point and added to the output variable calculated by the P or PD algorithm. The stored operating point remains effective until the operating point adjustment in manual mode is deactivated by selecting oFF MA.YP, or until a new operating point is adjusted in manual mode. If you deactivate operating point adjustment in manual mode, the output variable specified in manual mode will assume the calculated value within approx. two seconds.

3.4.7 F.FOR Feedforward control

You may use the input WE for feedforward control (see section 3.3.1). The disturbance signal can be multiplied and additively linked by parameters according to the formula: ± (WE – FC.K1) FC.K2 + FC.K3. The following then applies: (WE – FC.K1)≥0.

The signal is then connected to the controlled variable. FC.K1, FC.K2 and FC.K3 are constants you have to define in parameter level. The mathematical sign of the formula stated above is determined in the F.FOR function.

This function enables you to increase or decrease the actual value. Upon activation of the binary input, the input signal X is additively linked to the parameter AV.K1.

Upon deactivation of the binary input, the input signal X is used for control again. In parameter level, the parameter AV.K1 is given in percent ranging from –110 to 110 %. When entering, for example, AV.K1 = 30 %, the current value for X will be increased from 50 to 80 %.

3.5 Output functions

This main group enables you to define the output functions of the compact controller. You may specify whether the compact controller operates with continuous-action or switching output. The output signal can be limited and ramps can be defined. You can also output X, WE or XD to the continuous output and transfer them to a recorder. In addition, mathematical adaptations can be made for the continuous-action output. The switching outputs can be used as binary outputs to signalize varying operating conditions. The following functions can be assigned to the binary input in this main group: locking of the output signal, manual/automatic changeover, starting an output ramp or initializing the second output variable Y1K1.

termines the transit time of the output variable ramp and, thus, the speed. TSRA refers to an output change of 100 % (see Fig. 10).

The output ramp is started by activating the binary input bi1. You may choose between starting the ramp with either –10 % or with the value of the parameter Y1RA. The ramp is deactivated in manual mode and upon restart after a power failure.

Two-step output

The two-step output can only assume two states: on (1) or off (0). This controller output is used for applications, such as electric radiators with thermostat behavior.

This version of the two-step output corresponds with a monitoring of the limit value violation by the Y

PID

The parameters dead band TZ and XSDY determine the switch-on and switch-off point of the two-step output. The parameter XSDY represents the differential gap and is used to prevent the two-step output from constantly switching on and off upon small deviations.

The electrical wiring is the same as for the binary output BO1 (see section 7). The two-step output with pulse-pause modulation (PPM) is described on page 45.

Three-step output with internal position feedback

For the three-step output with internal position feedback, the position of a valve is determined by the transit time of the connected actuator. This transit time needs to be specified as parameter TY.

The output variable of the three-step output can assume three values: –100 %, 0 and 100 %. This controller output is used, e.g. for electric actuators, the three output variables corresponding to “counterclockwise rotation”, “motor switched off” or “clockwise rotation”. A definable dead band lies between both switching points. The dead band is the parameter TZ (see Fig.

12). In addition, you have to specify the parameter XSDY, which represents the differential gap. The differential gap applies to both switching points. Note that the differential gap must always be

smaller than

A comparator produces the difference between the Y

PID

signal and the feedback signal YR. This

difference constitutes the output value for the three-step output. The following applies:

When the difference is greater than

and larger than 0, the Y+ output is activated.

When the differential gap is greater than

and smaller than 0, the Y– output is activated.

When the difference is smaller than

This type of three-step output feeds back the position of a connected actuator externally via the WE input using, for example, a potentiometer. Apart from that, this three-step output is similar to the three-step output with internal position feedback.

When a potentiometer is used for external position feedback, it needs to be calibrated as described in section 3.9.5.

3.6 ALRM Alarm functions

This main group enables you to determine the functions of the limit relays L1 and L2. The limit relays monitor variables as to whether they exceed or fall below a limit value. The limit

relay can assume two switching states. When the switching condition is fulfilled, the limit relay is closed, if not it is open.

The functions LIM1and LIM2 determine which variable will be monitored by the limit relay L1 or

L2, and also whether the limit relay becomes active when limit values are exceeded or not reached.

The limit value of the selected variable is defined in parameter level via LI.X, LI.WE, LI.YPID or LI.XD. In addition, you have to set the parameter L.HYS to define a differential gap (hysteresis). The differential gap is the distance between the points where the limit relay switches on and off.

It is given in percent referred to the measuring range. Fig. 18 illustrates the function of the limit relay, exemplifying the monitoring of the controlled

variable X with the associated parameters. First case: the limit relay monitors the controlled variable for exceeding a preset limit. The limit

relay is activated when the controlled variable X increases and reaches the preset limit LI.X, LI.WE, LI.YPID or LI.XD. When the controlled variable decreases and reaches the preset limit minus the differential gap L.HYS, the limit relay is deactivated.

Note that LI.X and LI.WE are stated in absolute values. However, in Fig. 18, LI.X is given in percent!

Second case: the limit relay monitors the controlled variable X for falling below a preset limit. The limit relay is activated when the controlled variable decreases and reaches the preset limit LI.X, LI.WE, LI.YPID or LI.XD. When the controlled variable increases and reaches the limit LI.X plus the differential gap L.HYS, the limit relay is deactivated.

When limit relay 1 is activated, the icon appears on the display. The icon is displayed when limit relay 2 is activated.

4 Practical examples

In this section, we will show you how to configure your TROVIS 6493 Compact Controller to implement fixed set point control, follow-up control and follow-up control with function generation. We assume you know how to operate the controller. If not, read section 2. Note that there are two controller versions due to the different inputs In2!

4.1 Fixed set point control

For this example, we have chosen a simple temperature control loop as illustrated in Fig. 19. The controlled variable X represents the flow temperature, which is measured at the input IN2

via a Pt 100 sensor. The flow temperature is to be controlled to a fixed reference variable value. The TROVIS 6493-01 Compact Controller issues a continuous 4 to 20 mA signal as output variable Y. To perform this control task, you only need to define the reference variable and the control parameters. The reference variable can be set directly in operating level using the cursor keys. The control parameters,

however, must be defined in setup level in the main group CNTR. All other required settings are configured in the compact controller by default. The table below lists the settings you require:

4.2 Follow-up control

A follow-up control loop is illustrated in Fig. 20. In this example, a pressure between 0 and 10 bar is controlled and measured via a two-wire transmitter. The two-wire transmitter could be the SAMSOMATIC Type 3994-0050 Transmitter, for example. The external reference variable is provided by a 4 to 20 mA signal. In addition, we want to be able to switch to a fixed value for the

internal reference variable. The control valve with positioner is controlled by a continuous output variable Y ranging from 4 to 20 mA. The controller version TROVIS 6493-02 with two mA inputs is used in this example.

Proceed as follows:

The controlled variable X represents the pressure p1, which is measured via a two-wire transmitter and connected to the input In2. This input is designed for 4 to 20 mA by default, i.e. it does not need to be changed. However, you have to set the measuring range for this input to 1 to 10 bar. To do this, select the -CO- IN2 function in the main group IN, and define the measuring range in the parameter level.

The external reference variable WE is applied to the input In1 asa4to20mAsignal. The input In1 is originally set up for 4 to 20 mA, therefore it does not need to be changed. However, you must determine the measuring range for the reference variable in parameter level with 0 to 10 bar. To do this, open the parameter level in the main group IN in the function

-CO-IN1. By default, WE is deactivated. To activate WE, enter the -CO- SP.VA function in the main group SETP and select WE. Set WE to "on". Additionally, set the measuring range of W (internal reference variable) to 0 to 10 bar. In operating level, you may now select W or WE as reference variable. When defining WE as active reference variable, follow-up control is implemented automatically. When defining W as active reference variable, you have set up fixed set point control. For this control action, you can enter the reference variable value in operating level via the cursor keys.

Control action should be PID, not PI as specified in factory defaults. Go to the main group CNTR, and change the settings of the -CO- C.PID function to PId. Additionally, alter KP, TN, and TV in the parameter level.

4.3 Follow-up control with function generation

We will show you how to use function generation exemplifying an outdoor temperature-sensitive flow temperature control loop, as illustrated in Fig. 21.

The controlled variable represents the flow temperature. The outdoor temperature is measured by a Pt 100 sensor and converted into a flow temperature through function generation. The relationship

between outdoor temperature and required flow temperature is given in the table below. The resulting characteristic serves as external reference variable. The Type 6493-01 Compact Controller controls the valve via a three-step signal with internal position feedback.

Proceed as follows:

The controlled variable X represents the flow temperature, which is measured by a two-wire transmitter. In controller version 6493-01, two-wire transmitters can only be connected to the input In1. This input is adjusted to 4 to 20 mA by default, i.e. it does not need to be changed. However, you have to adjust the measuring range for this input to a range of 0 to 150 °C. Additionally, you must assign the controlled variable X to input In1.

The outdoor temperature is represented by the external reference variable WE and applied to the input In2. This input is already set up for Pt 100 sensors by default. The measuring range is also fixed. Nevertheless, you have to assign WE to input In2. By default, WE is not activated. Set the measuring range for the internal reference variable W to 0 to 150 °C as well. In operating level, you may choose between W and WE. When selecting WE as active reference variable, follow-up control is implemented automatically.

Define the relationship between outdoor temperature and flow temperature in the main group IN with the function FUNC and WE in the parameter level.

5 Start-up

When all the inputs and outputs as well as the power supply are connected, the compact controller must be adapted to the desired control task. This means that you have to configure and parameterize the controller. Appendix C contains a checklist to fill in the adjusted settings if you wish.

The compact controller must be adapted to the dynamic behavior of the controlled system via the parameters KP, TN and TV to ensure that the system deviations caused by disturbances can be eliminated or largely suppressed. There are two ways to adjust these parameters, either via start-up adaption (see section 3.8.1) or via manual optimization. The latter is described in the following sections. We can only give general instructions. If appropriate settings have not yet been determined for your controlled system, proceed as follows:

Note! Make sure the connected control valve is closed before you start manual optimization!

1. Press the manual/automatic key (13) to switch to manual mode. The icon is displayed.

2. Use the cursor keys to change the output variable to a value at which the control valve slowly opens.

3. Proceed as described below for the desired control action.

5.1 P controller

Enter KP = 0.1.

Adjust the reference variable to the desired value in operating level.

Use the cursor keys to change the output variable to a value at which the control valve slowly opens and the error Xd becomes approximately zero.

Switch to automatic mode.

Increase the KP value until the controlled system tends to oscillate.

Slowly decrease the KP value until the oscillations are eliminated.

To eliminate the remaining system deviation, proceed as follows: switch to manual mode. Change the output variable so that the error Xd = 0. Read the value displayed for the output variable and adjust the parameter Y.PRE (CNTR, C.PID) to this value.

Note! Each change of the reference variable also changes the operating point!

5.2 PI controller

Enter KP = 0.1 and TN = 1999.

Adjust the reference variable to the desired value in operating level.

Use the cursor keys to change the output variable to a value at which the control valve slowly opens and the error Xd becomes approximately zero.

Switch to automatic mode.

66 EB 6493-1 EN

Start-up

Increase the KP value until the controlled system tends to oscillate.

Slightly decrease the KP value until the oscillations are eliminated.

Decrease the TN value until the controlled system tends to oscillate.

Slightly increase the TN value until the oscillations are eliminated.

5.3 PD controller

Enter KP = 0.1, TV = 1 and derivative-action gain TVK1 = 1.

Adjust the reference variable to the desired value in operating level.

Use the cursor keys to change the output variable to a value at which the control valve slowly opens and the error Xd becomes approximately zero.

Switch to automatic mode.

Increase the KP value until the controlled system tends to oscillate.

Increase the TV value until the oscillations are eliminated.

Increase the KP value until the oscillations appear again.

Increase the TV value further until the oscillations are eliminated.

Repeat this procedure several times until the oscillations can no longer be suppressed.

Slightly decrease the KP and TV values to allow the controlled system to settle down.

To eliminate the remaining system deviation, proceed as follows: switch to manual mode. Change the output variable until the error Xd = 0. Read the value displayed for the output variable and adjust the parameter Y.PRE (CNTR, C.PID) to this value.

Note! Each change of the reference variable also changes the operating point!

5.4 PID controller

Enter KP = 0.1, TN = 1999 and TV = 1.

Adjust the reference variable to the desired value.

Use the cursor keys to change the output variable to a value at which the control valve slowly opens and the error Xd becomes approximately zero.

Switch to automatic mode.

Increase the KP value until the controlled system tends to oscillate.

Increase the TV value until the oscillations are eliminated.

Increase the KP value until the oscillations appear again.

Increase the TV value until the oscillations are eliminated.

Repeat this procedure several times until the oscillations can no longer be suppressed.

Slightly decrease the KP and TV value to allow the controlled system to settle down.

Decrease the TN value until the controlled system tends to oscillate again. Now increase the value again slightly, so that the oscillations disappear.

7 Electrical connections

The compact controller has screw terminals suitable for lines up to 1.5 mm². For electrical installation, you are required to observe the VDE 0100 regulation and the regula-

tions applicable in the country of usage. To avoid measurement errors or other faults, use screened cables for the signal lines of the ana-

log and binary inputs running outside the switching cabinets. Within the cabinets, these signal lines have to be installed separately from the control and network lines with sufficient space between them.

Ground the cable screenings on one side in the neutral point of the measuring and control system.
