4 CONFIGURATION
4.1.4. « EXT.MEM » Option
This option enables the generation of a dose quantity which has already been entered into
the memory (7 in total) from a remote position by using the binary data inputs (See § 4.2.2.).
The following example describes the various methods of connection.
Example: Connection to a PLC (compact version)
L+(12...30VDC)
GND
The selection of a dose quantity from the memory (1 to 7) is carried out by encoding the
binary data at inputs 1,2 and 3. The following table shows the logic value at each input to
provide each of the desired seven quantities:
Binary Data Input 4 provides the start / pause function (from a push button, for example).
Output 5 is a transistor output (open collector) which provides Dose Controller status
information. For example, it can be used to feed an indicator lamp. The following status
conditions can be indicated:
Lamp extinguished
Lamp lit
Slow flashing (1 Hz)
Rapid flashing (3.5 Hz)
