'HYLFH FRQILJXUDWLRQ DQDORJ GHYLFHV
ODEZRUOGVRIW device configuration makes it possible to integrate laboratory devices with analog
inputs or outputs into your measurement sequence schedules.
With the DC2 the laboratory device output signals are evaluated and the DA2 provides analog
signals in order to trigger the inputs of a laboratory device.
Both devices provide different current and voltage ranges of up to 20 mA or 10 volts.
The configuration is made up of the following parameters:
 Designation of the analog device for identification in the DC2/DA2 selection list.
 Current or voltage range (two current ranges and three voltage ranges available).
 Unit of measurement of the measuring or control value (1/min, °C, etc.).
 Measuring or control value which corresponds to the maximum analog voltage (or current).
 Measuring or control value which corresponds to the minimum analog voltage (or current).
Carry out the following instructions:
x Call up the parameter window by clicking the 'HYLFH &RQILJXUDWLRQ command and the
corresponding submenu in the pull-down menu "Tools".
Configuring the First Analog Device
1. Define the device current or voltage class by clicking on the corresponding option push-
button in the "Output" or "Input" field.
2. Enter the device 'HVLJQDWLRQ into the text field.
3. Enter the 8QLW of measurement or control value into the text field, e.g. 1/min.
4. Enter the 0HDVXULQJ RU &RQWURO 9DOXH which corresponds to the maximum analog
voltage (or current).
5. Enter the 0HDVXULQJ RU &RQWURO 9DOXH which corresponds to the minimum analog
voltage (or current).
6. &RQILUP the entry by clicking on the push-button with the same name. The analog device
is included in the list.
Configuring Additional Analog Devices and Saving the List
1. Additional analog devices may be configured in the same manner as described above.
2. Save the configuration list by clicking on the &ORVH push-button.
