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. The
“Measurement start“ signals can be initiated via the process channel or the opto couplers.
Simultaneous initiation leads to an error message.

Notes
IN0
Measurement start input 1
Optocoupler input 1,
24 V active
IN1
Measurement start input 2
Optocoupler input 2
24 V active
IN2
Measurement start input 3
Optocoupler input 3
24 V active
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).
