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.
Connection example:
Batch controller 8025
The selection of a dose quantity from the memory (V1 to V7) is carried out by encoding
the binary data at inputs IN1,IN2 and IN3. The following table shows the logic value at
each input to provide each of the desired seven quantities:
Binary Data Input IN4 provides the start / pause function (from a push button, for
example).
Output OUT is an NPN transistor output (open collector) which provides Batch Controller
status information. For example, it can be used to feed an indicator lamp. The following
status conditions can be indicated:
Lamp OFF
Lamp lit
Slow flashing (1 Hz)
Rapid flashing (3.5 Hz)
