3 Safety rules
3.1 Installation / Commissioning / Parameterization
• These operating instructions has to be carefully studied beforehand and the instructions are to be
complied with.
• Prior to the installation, all power supply voltages and any other energy sources have to be disconnected.
• During unpacking and when installing it, the card must only be gripped on the housing. Any contact with
soldering points, components and contact pins of the card should be avoided.
• W rong manipulations by the personal cannot be prevented by the card.
• Before the switching on of the supply voltage, the fuse protection, the correct wiring and the conformity of
the power supply voltage with the permissible supply voltage range have to be verified.
• The control monitors the working conditions within the electronic and within the
installation. Uncontrolled movements caused by unforeseen errors cannot be
prevented.
• Danger for persons has to be avoided by installing an emergency stop device
which cuts off the power to the system.

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 value Digital input 6 Digital input 7 Digital input 8
External preset value
1
2

311

51 1
611
7111
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
LED red: Indicates an error

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
