1.3 Electro-magnetic compatibility (EMC)
The EMC of the device was tested using an accredited testing laboratory (emitted interference according to DIN EN 61000-6-3 and
immunity to interference according to DIN EN 61000-6-2 evaluation criterion "B"). The test set-ups only represent typical use. This EMC
testing does not release the user from carrying out adequate prescribed EMC testing of their complete system (according to Directive
2004/108/EC). If the EMC of the complete system must be further amplied, the following measures can be tested and introduced:
■The required smoothing capacitor in accordance with Chapter 1.2, "Electrical Data" is not only needed to ensure the device functions
correctly, but also to guarantee compliance with EMC guidelines (conducted emitted interference).
■The equipment should be installed in an metal cabinet (shielding)
■Supply lines, such as inputs and outputs to and from the device, should be as short as possible. If necessary they should be shielded
and twisted in pairs (to reduce the antennae-like effect for increasing the immunity to interference).

3Installation, operation and maintenance information
3.1 Information on setting
The card is parameterised using four buttons and a two-digit seven-segment display. All operations are performed using the buttons
arranged in a square. In accordance with the normal installation position of the card (plug connections at bottom), the buttons are
labelled top, bottom, right and left.
Parameters that can be adjusted by the user can be selected by navigating in a menu. These are shown in the display with their
(standardised) values and can be modied at the push of a button. Adjusted parameter values are effective immediately once the
modification is made, so that the user receives immediate feedback on the effects of the setting.
However, nal and permanent adoption requires confirmation (at the push of a button). If this does not take place, the adjustment is
aborted after 10 seconds and all settings are as they were prior to the attempted adjustment.
Navigation
The right and left buttons are used to navigate in the menu. The right button is generally used to go deeper into the menu, whereas the
left button is used to go up one level (back). The up and down buttons are used to increase and reduce values.
User parameters
Parameter Designation min max Default Standardisation
P0 Minimum current Imin 0 99 0 20 mA/increment
P1 Maximum current Imax 0 99 50 20 mA/increment
P2 Ramp time, up Tup 1 99 10 100 ms/increment
P3 Ramp time, down Tdown 1 99 10 100 ms/increment
P4 Dither amplitude l 1 99 0 %
P5 Dither frequency (dither period) f 20 (50) 100 (10) 50 (20) Hz (ms)
Note
Note that the parameter values can only be modied in discrete steps using the keypad. Conversion factors that match physical
values to the respective increments are stated under "Standardisation".

3.2 Setting instructions
Changing the parameters
The amplifier is in normal operation.
1. Press and hold the "right" button.
✓P0 is shown in the display. The amplifier is now in parameterisation mode.
2. Use the "up" and "down" buttons to select a parameter from P0...P4.
3. Press the "right" button to select the displayed parameter.
✓The current standardised numerical value of the parameter is displayed. For the meaning of the numerical value and the parameters,
see
Note
Modifications are effective immediately once the value is changed. However, permanent adoption of the values must be
conrmed rst.
4. Press the "up" or "down" button to modify the value.
5. Press and hold the "right" button to conrm the value.
✓The amplifier acknowledges the adoption of the parameter by briey displaying the value 0C
Note
If modied parameters should not be saved, the change can be discarded by pressing the "left" button.
The amplifier switches back to normal operation.
