External I/O control

The system is normally controlled via the process channel. The exception is the signal
"Measurement start", which, for fast procedures, can also be controlled via the Optocoupler inputs
(IN). A mixed operation is also possible. The control cannot, however, be made simultaneously by
both signal sources.
The "Measurement start" signals can be initiated via the process channel or the opto couplers.
Simultaneous initiation is not possible. That means that the initiation of measurement start is not
accepted by optocouplers, if measurement start of the process channel is active or not processed.
The same applies to the other way.
Signal Meaning
IN0 Measurement start input 1
IN1 Measurement start input 2
IN2 Measurement start input 3
Table: Optocoupler - inputs
The "Measurement start" inputs are linked in different combinations via AND. The following
configuration can be selected in the control unit:
• IN0
• IN0 and IN1
• IN0 and IN1 and IN2
In addition the signals 0-, 1-, 2-sheet, ENABLE and warning are available for further processing via
Optocoupler (OUT).
Signal Meaning
OUT0 Output 0-sheet
OUT1 Output 1-sheet
OUT2 Output 2-sheet
OUT3 Output ENABLE
OUT4 Warning
