Operating guide to Amplifier SD1X0

4 Construction and Function

Refer to the section "Block diagram SD1 " page 6

4.1 Introduction

• The Amplifier is constructed as an Eurocard

• The Eurocard is built into a housing made of alu

• All inputs and outputs have to be contacted trough the screw-on/plug-in connector strip

• The Version SD1102D20-AA has a RS232 (serial) interface, via which the parameterization and the

diagnostics can be made by using the multi-function terminal (MTG02) or PC-Terminalsoftware TESO

• The Version SD1302D20-AA has a RS232 (serial) interface, via which the parameterization and the
diagnostics can be made by using the PC-Parameterization software PASO

4.2 Description of the Function

The Amplifier serves for controlling proportional valves with one or two solenoids and includes constant
current control. Dither frequency and level are adjustable independently. Solenoid outputs are made short
circuit proof. Preset values can be connected in the range of 0 ... 10V or 0 ... ±10V. The analog inputs can be
used also as current inputs 0 ... 20mA or 4 ... 20mA. By that, the Amplifier can be adapted to all common
input signal types. By selecting one of the 4 operating modes, the Amplifier can be set in very universal.
Further, two independently working control loops are selectable.
Amended parameters can be stored in a non volatile memory to have them available when the control system
is switched on again.

4.3 Analog inputs

• The applied analog signal is digitalized in the 10-Bit A/D converter

Attention: By the input range 0 ... 8V, 0 ... 5v or 4 ... 20mA, the resolution is < 10-Bit!

• Differential inputs
Differential inputs must be used if the ground potential of the external preset value generator does not
agree with the analog ground on the Amplifier card.
If the differential input is intended to use like an analog input against analog ground, the - (minus)
connection of the differential input must be connected to the analog ground.

• Analog input with cable break detection
The preset value must be a current signal 4 ... +20mA or a voltage signal from a potentiometer. If a
potentiometer is used, its ground connection must be wired to the terminal "Analog ground with cable
break detection".

• Analog input 1 (for differential voltage signal)
Input voltage range: 0 ... +10V / 0 ... +8V / 0 ... +5V

• Analog input 2 (for differential current signal)
Input current range: 0 ... +20mA / 4 ... +20mA

• Analog input 3 (for voltage signal against analog ground)
Input voltage range: 0 ... ±10V / 0 ... ±8V / 0 ... ±5V

• Analog input 4 (for current signal against analog ground)
Input current range: 0 ... +20mA / 4 ... +20mA

4.4 Digital inputs

• Digital inputs 1 and 2 are active-low (refer to section "Electrical specifications" page 4) and not galvanically
separated.

• Digital inputs 3 to 8 are acitve-high (refer to section (refer to section "Electrical specifications" page 4) and
galvanically separated via optical couplers.

Attention: Connect common optical coupler ground (14z)!

• Digital input 1 (Disable solenoid A)
If this input is set, solenoid output A is disabled.

• Digital input 2 (Disable solenoid B)
If this input is set, solenoid output B is disabled.

• Digital input 3 (Enable control)
If this input is set, the Amplifier is enabled. Without this enable, no movements can be made.

• Digital input 4 (Solenoid B active)
If this input is set, the solenoid B is acitve (only in the mode of operation 1).

• Digital input 5 (Ramp Off)
The ramp can be temporarily switched off by setting this input. If the ramp is never required, this input
needs not to be set since the ramp time is set to 0s.

• Digital input 6 - 8 (Fixed preset values)
7 fixed preset values, selectable in binary form, are available. When a fixed preset value is selected via
the digital inputs 6 - 8, the external preset value is ineffective.
The following inputs must be set to activate the corresponding fixed preset value:

Fixed preset values 1, 2 and 4 can be selected directly, i.e. without coding.

4.5 Outputs

• Proportional solenoid outputs A and B
The 2 solenoid outputs have a current output pulse-width-modulated at 1000Hz with superimposed dither.
The polarity of the connected solenoids is irrelevant. The outputs are short circuit proof and may be
loaded up to 1.8A.

• Digital output 1 (Error)
This output becomes active, when an error is present.

• Digital output 2 (Solenoid B active)
This output becomes acitve, when the solenoid B is active.

• Light emitting diodes LED green / yellow / red
LED green: Supply voltage is present
LED yellow: Solenoid B is acitve

4.6 Mode of operation

The following 4 mode of operation are possible:

• Mode of operation 1
With one analog input (voltage or current) and the digital input 4 (Solenoid B acitve), solenoid A and
solenoid B from a directional valve will be controlled.
0% ... 100% preset value, digital input 4 not active = Imin ... Imax solenoid A
0% ... 100% preset value, digital input 4 active = Imin ... Imax solenoid B

• Mode of operation 2
With one analog input (voltage or current), solenoid A and solenoid B from a directional valve will be
controlled.
0% ... 50% preset value = Imax ... Imin solenoid B
50% ... 100% preset value = Imin ... Imax solenoid A

• Mode of operation 3
With one voltage preset value from 0 ... ±100% at analog input 3, solenoid A and solenoid B from a
directional valve will be controlled.

-100% ... 0% preset value = Imax ... Imin solenoid B
0% ... +100% preset value = Imin ... Imax solenoid A

• Mode of operation 4
In this mode of operation, two solenoids can be controlled independently from each other. Each solenoid
is controlled by separate voltage or current input.
0% ... 100% analog input A = Imin ... Imax solenoid A
0% ... 100% analog input B = Imin ... Imax solenoid B

6 Commissioning

Please refer to the section "Safety rules" on page 7.

6.1 Installation / Connection

The Amplifier should preferably be installed in a switchboard cabinet.

For an installation / connection appropriate for EMC, the following points absolutely have to be observed:

• The housing has to be grounded on an electrically conducting sub-surface using a conductor strand with a
large cross section.

• The shielding connection (1) on the screw-on/plug-in connector strip has to be connected with the
switchboard cabinet with an as short as possible conductor with a strand cross section >= 1,5 mm

• The screening of the cable on the housing side must only be connected with the switchboard cabinet
using a large surface area and low Ohm connection (best by means of a clamp shackle).

• Solenoid- and signal cables must not be laid parallel to high voltage cables.

6.2 Connection instructions

The contact assignment of the following description refers to the section "Connection examples" page 15.

2.

6.2.1 Supply voltage

• For the dimensioning of the 24VDC power supply, the maximum power demand of the solenoid has to be
calculated (in case of directional valves, only the maximum power demand of one solenoid has to be
considered). This power then has to be increased by the no load power from the Amplifier (refer to the
section "Electrical specifications" page 4).

• The limit values of the supply voltage and its residual ripple indispensably have to be complied with (refer
to the section "Electrical specifications" page 4).

• The Amplifier has to be protected with a slow acting fuse. The rating of this fuse should correspond to
approx. 1.5 times the current calculated above.

6.2.2 Solenoid outputs

For the solenoid outputs, the polarity, with which the solenoids are connected, does not matter. The following,
however, has to be observed:

• The conductor strand cross section has to be adapted to the solenoid current

• Screened cables have to be used; the screen must be grounded only on the switchboard cabinet side.

24V

• Digital inputs 3 - 8 are acitve-high and galvanically separated via optical couplers.

• In order to use the galvanically separation, the connection "Digital ground" (18) has to be connected to the

ground of the external digital signal transmitter.

• If no galvanically separation is necessary, the "Digital ground" (18) can be connected with the minus of the
24VDC power supply.

• For activation, they have to be connected to +24VDC.

7 Settings

Please refer to the section "Safety rules" on page 7.

7.1 Introduction

• The system- and parameter settings can be made it depends on the card version either via the RS232
interface with the multi-function terminal MTG02 resp. the PC-Terminal software TESO or the PC­Parameterization software PASO.

• For information about the operation via the multi-function terminal MTG02 resp. PC-Terminalsoftware
TESO please refer to section "Cyclic menu construction" page 28.

• For information about the operation via the PC-Parameterization software PASO please refer to section
"PASO Installation and Operation" page 29.

• The following instructions refer to the Menu order of the PC-Parameterization software PASO. To look for
the corresponding points in the version with multi-function terminal MTG02 resp. PC-Terminal software
TESO, the corresponding cyclic menu construction is also displayed.

• Depending on the software version and connecting card type, certain settings may be blocked.

7.2 General

In order for some of the menus resp. sub-menus listed below to be able to be selected, first a parameter set
must be present int the memory or else a new one has to be established. To do this, one of the following
commands has to be executed:

• File_New

• File_Open

• Start PASO with the connection to the Amplifier (in this case, the data are loaded from the Amplifier)

7.3 Tips for the first commissioning

• Connect the power supply, leave the Amplifier still switched off

• Switch off the hydraulic drive (hydraulics switched off)

• Carefully check the connections

• Switch on the power supply

• Establish the communication with PASO (connect the PC and the Amplifier with an RS232 cable and start

PASO)

• In the menu "Configuration", define the correct input for the preset value

• In the menu "Parameters_Valves", set the desired current for the solenoids

7.4 File - Menu (only PASO - Version)

Contained in the File menu are the menu points, which concern the file handling and the printing of the
parameters. In the "On Line Mode", some of these menu points are blocked..

7.4.1 File_New

This menu point is active only in the "Off Line Mode".
With this command, a new file can be opened. A selection window will be displayed. In this window, the
desired function from the PASO can be selected. The selected function should correspond to the function of
the connected digital card. All parameter values are set to standard values. The required values can now be
entered.

7.4.2 File_Open...

This menu point is only active in the "Off Line Mode".
With this command, an existing file from a storage medium is opened. First the file selection window appears.
In this window the required file can now be selected and opened with ”OK”. If the function of the selected file
does not correspond to the current function of the PASO, a message will be displayed. A selection is now
possible, if the event should be cancelled or if the current function from the PASO should change over to the

new function of the selected file. The parameter values can now be edited and changed as required under
the menu points “Configuration” or “Parameters”.

7.4.3 File_Save

With this command, the parameters are saved on a data storage medium. All parameter values of all input
windows are saved under the current file name. If no file name has been defined yet, then first the file
selection window appears (refer to File_Save as...).

7.4.4 File_Save as...

With this command, the parameters are saved on a data storage medium. All parameter values of all input
windows are saved under the file name entered.
First the file selection window appears (see File_Open). In this window the desired file name can now be
entered. If the file name is entered without an extension, then the extension “.par” is automatically assigned
to it. After actuating the key “Save”, the file information window appears (see File_File-Info). In this window
the required entries can now be made. With the key “Save”, the file is then finally saved under the selected
file name. With the key “Cancel”, one changes back to the file window.

7.4.5 File_Print...

With this command, the current parameters are printed in ASCII text format. The File_Print window is
opened. In this window one can now select, whether the printing process is to be to a printer or to a file.

If the output is to be to a printer, then the Windows printer selection window is opened.. In this window,
please do not select “Print to File”. If you do, a new program start might possibly be required and you
could lose any data not yet saved.

If the output is to be to a file, then the file selection window appears. In this window the desired file name can
now be entered. If the file name is entered without an extension, then automatically the extension “.txt” is
assigned to it.

7.4.6 File-Info

With this command, the file information of an existing file is displayed. The file information consists of the
following parts:

Date, time Date, time of saving.
File name: The file name, under which the file has been saved.
Card type: The type of digital control card at the moment of saving. If no card is connected, then this
indication remains empty. In case of saving during “On Line Operation”, this indication is
updated.
Operator: The name of the originating person.
Remarks: Possibility to enter remarks concerning the file.

When the File_Info window appears during the execution of the command “File_Save”, then the
corresponding entries can be made in the various fields (with the exception of “Date”, “Time”, “File name” and
“Card type”, which cannot be edited). When the File_Info window appears during the execution of the
command “File_File-Info”, then the various fields cannot be edited.

7.4.7 File_Off Line (On Line)

Off Line

With this command, the connection with the Amplifier is interrupted. All menu points, which call for a
communication with the Amplifier, are blocked. The PASO software now runs in the “Off Line Mode”. The
loading, saving and the editing of parameter files is possible in this mode.

Operating guide to Amplifier SD1X0

On Line

With this command, the connection with the Amplifier is established. The communication with the Amplifier is
briefly tested. If the connection works, then the user has the option of taking over the parameters from the
Amplifier or of transferring the parameters to the Amplifier. During the transfer of the parameters, the user
has the possibility of aborting the operation.

Before parameters are transfered to the Amplifier, a verification is carried out as to whether the version of the
Amplifier supports the parameter values. If this is not the case, then a message is issued and a transfer to
the controller is not possible.

If the parameters have been taken over by the Amplifier, then they are briefly checked. If one or several of
the parameters are outside the tolerance, standard values are assigned instead and a message is issued. If
the transfer was successful and the verification check was also successful, then the software subsequently
runs in the On Line Mode”. The loading of parameter files is not possible in this mode.

7.4.8 File_Exit

With this command, the parameterization program PASO is terminated. If parameter data have been
changed and have not yet been saved, then the question appears, as to whether these data should be saved.
When terminating, the current data from the configuration window are also saved.

10 PASO Installation and Operation

The parameterisation software PASO serves for the parameterising and diagnosing of digital control cards of
the WANDFLUH AG company. The software provides a user interface, through which by means of a
keyboard or a mouse all adjustments and settings can easily be carried out. The communication with the
digital control card takes place through a serial RS 232 interface.

The parameterisation software PASO can only be utilised in connection with a digital control card of
the WANDFLUH AG company. It is necessary to carefully study the operating instructions of the
connected digital control card beforehand.

10.1 PASO system requirements

A description of the different PASO versions is located in the file "history.pdf". This file is located in the
directory where the PASO will be installed.

In order to be able to correctly utilise the PASO, an IBM-compatible PC with the following requirements has to
be available:

• Processor 486 or higher, min. 33MHz, min. 8MB RAM
Recommended: 80586 66MHz or higher, 16 MB RAM or more

• Free harddisk storage space of minimum 4MB, plus storage space for program files

• Operating system MS-WINDOWS 95/98, NT 4.0 or higher

• Standard VGA or higher graphics card, recommended resolution 800x600

• At least one serial RS 232 interface (with Laptops resp. Notebooks without a serial interface, this can be

realised with a PCMCIA-card)

• Serial RS232 cable 1:1 (RxD and TxD not crossed)

10.2 PASO installation

The PASO software can be downloaded via the Internet free of charge (www.wandfluh.com/Download =>
PASO ED1/SD1 => Download Program files) or on request delivered on an installation-CD.

The installation of the PASO is then carried out by executing the file "setupPasoEd1vxxxx.exe", where "xxxx"
means the current version (e.g. setupPasoEd1v3000.exe, see also version index). An installation program
takes over the complete installation of PASO. To them, the Windows Installer must be installed. This is
normally a part of the Windows Environment. If not, please download it from the Microsoft Website.

If there is already a version of the PASO software installed on the PC, one can select if the existing version
should be overwritten or removed.

For all standard cards (Amplifier, Position controller, Pressure/Flow controller and Position controller PLUS),
the helpfiles are included in the setup and are installed automatically. For the special cards ED1AE, ED1AF,
ED1AG, ED1AP, SD1AY and SD1BA the helpfiles can be downloaded separate via the internet
(www.wandfluh.com/Download => PASO ED1/SD1 => Download Helpfiles for Special types)

10.3 PASO connection to the digital card

The connection between the PC, on which the parameterisation software PASO is installed and the axis
controller takes place through the serial RS 232 interface. To do this, a 1:1 cable (RxD and TxD not crossed)
has to be connected with the desired output port on the PC and with the RS 232 socket on the axis controller.

Operating guide to Amplifier SD1X0

The parameterisation software PASO runs in one of two modes:

• In the "Off Line"-mode, the processing of the parameter files is possible. The communication with the axis
controller is not active. A connection is not necessary.

• In the "On Line"-mode, there is active communication with the axis controller card. Every change becomes
immediately effective in the axis controller. In this mode, the loading and processing of files is not
possible. Solely the saving of the currently active parameters into a file is possible.

The change between the two modes takes place through the menu point “File_On Line / Off Line”. In case of
an interference in the communication, the controlling of the axis controller is not assured anymore. An error
message follows and the PASO software automatically changes over to the "Off Line"-mode.

When the parameterisation software PASO is started up, a check takes place, as to whether a
communication with the axis controller is possible. If no communication can be established, an error
message appears. The reason for this message is either a not connected - or a not switched on axis
controller, or else on the PASO side not the same interface has been selected as the one used for the
connection cable to the axis controller. In the latter case, one must reply with “No” and after the PASO start
has taken place one changes the interface port setting in the menu "Configuration_Interface (only PASO­Version)" page 24.

If one replies with “No”, then an additional message appears. The PASO software is set to the "Off Line"­mode. All menu points and keys, which involve an action in connection with the communication, are then
blocked. All other functions of the parameterisation software PASO, such as the processing of parameter
files, can be utilised without any limitation.
If one replies with “Yes”, then it is once again checked, whether now a communication with the digital
controller card is possible.

If the interruption of the communication occurs during the operation of the parameterisation software PASO,
then an error message appears and the PASO software is set to the "Off Line"-mode. All menu points and
keys, which involve an action in connection with the communication, are now blocked.

In order to re-establish a communication, the menu point "File_Activate On Line" has to be selected.

If a communication with the connected card is possible, a check will be made, if the current function from the
PASO correspond to the function of the connected card type. If yes, the parameters will be transfered. If no,
in case of "Take over", a question will be displayed if the current function from the PASO should be changed
or not. In case of "Reprogram", an error message will be displayed and the parameters can not be transfered.

10.4.3 Starting of PASO

Following the successful installation, the parameterisation software PASO can be started by double-clicking
on the PASO - icon. Certain settings of the PASO software, e.g., the selected interface port, are saved in the
file “konfig.kon”. When PASO is started for the first time, the configuration values int this file are set to
standard values. During the course of running the program, these values can be corrected.

After the start-up, the Start window appears:

Header line

Menu line

Icon list

Status line

During the start-up, the parameterisation software PASO checks, whether a digital controller card is
connected. If no communication can be established (communication interference or no axis controller
connected), an error message appears. All menu points and keys, which involve an action in connection with
the communication, are then blocked. All other functions of the parameterisation software PASO can be
utilised without any limitation.
If the communication works without any interference, the software PASO checks, if the current function of the
PASO correspond with the function of the connected digital controller card. If no, a question will be displayed
if the current function from the PASO should be changed or not.
If the function is ok or will be changed, the parameters are loaded from the card and subsequently a
verification of the axis controller values takes place. If one or several parameters are outside the
corresponding tolerance, they are replaced with standard values and a message is issued (refer to section
"Limiting value error" page 33). In this case the communication is set to the "Off Line"-mode. The user now
has the possibility to check the parameters and if necessary to correct them. The communication is resumed
again via the menu point “File_On Line”. Subsequently one has to select the option “Re-program the axis
controller”, in order for the corrected values to be made active on the axis controller.

The menu points in the menu line can be selected in the following manner:

• by clicking on them with the mouse

• by actuating the key "ALT" and the underlined letter of the required menu point

• if a menu point has been selected, then by means of the keys "Arrow left" and "Arrow right" one can

change to the next menu point and with the keys "Arrow up" and "Arrow down" one can change to the next
sub-menu point within the menu selection field.

Operating guide to Amplifier SD1X0

In the header line of the window, the name of the current file is always displayed. If no existing file has been
loaded or if the data have not been saved to a file, then this line reads ”noname”. Also the current function of
the PASO is displayed.

The following states will be displayed in the status line:

• 1. field: Selected RS232 interface

• 2. field: Current mode (On line or Off Line)

10.4.4 Store parameter on the controller card

Each new input value is immediately transferred to the connected controller card after the completion of the
input field (either by pushing the key ENTER or by activating another input field).

If the window is closed with the key "OK", the values are stored in the connected controller card so that they
are available after the controller card is switched on again (non-volatile memory).

If the window is closed with the key "Cancel", the previous current values are active again. All inputs made in
the current window are cancelled.

10.4.5 Limiting value error

Each incoming parameter (either transferred via the serial interface or loaded from a file) is checked against
the limiting value. If a parameter is smaller or bigger than its limiting value (= limiting value error), it is set
automatically to the default value and the following window appears:

Parameter: Name of the parameter with the limiting value error
Current value: Current value of the parameter
Min. value: Minimum allowed value of the parameter
Max. value: Maximum allowed value of the parameter
Default value: Default value of the parameter

After pressing the key "OK", the current value is overwritten by the default value.

Normally, a limiting value error does not happen. However, in the following cases it can happen:

• loading a file, in which parameter values have been changed from outside

• reading parameter values from a connected controller card with another configuration than the current

configuration in the PASO (only if the controller card was changed while in the "On Line"-mode)

• if the transmission of the parameter values is wrong

10.5 Description of Commands

The description of the individual commands and parameters is contained in section "Settings" page 17.

11 Disposal

• The electronics card has to be disposed of in accordance with the generally applicable regulations of that
country, in which it is being used.

• Electronics cards are recycled by companies specialised in this field.
