4.2.4 «EXT.MEM» Option
Generation of a volume previously entered into the memory (7 in total) from a remote po-
sition by using the binary data inputs (See § 4.2.2.). The following example describes the
various methods of connection.
Batch controller 8035
Fig. 6 Connection example
The selection of a volume from the memory (1 to 7) 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:
Volume
Input IN1
Input IN2
Input IN3
1: Input enabled (switch closed)
0: Input disabled (switch open)
Input IN4: Start / Pause function (from a push button, for example).
Output OUT: Transistor output (open collector)
Provides Batch controller status information. For example, it can be used to feed an indica-
tor lamp. The following status can be indicated:
Lamp off:
Lamp on:
Slow flashing (1 Hz):
