The following information is processed at the binary inputs or output at the binary outputs:
• Binary inputs:
Signal for process access : The analyzer can only perform activities that require sample
(measurement, calibration, cleaning) when the signal is active. The time and the sequence
of activities correspond to the settings in the setup. All activities that require sample are
delayed as long as the signal is inactive.
• Binary outputs:
• Measurement active signal: Indicates that a measurement is currently running. The
signal is not active in the event of a calibration or cleaning.
• Sample required signal: The signal is active for a configurable time before every activity
that requires sample. This makes it possible to activate an external pump or a dilution
module, for example.

3. Link the binary inputs with the analyzer: select Menu / Setup / Analyzer / Extended
setup / Signal for process access .
4. Select measuring channel SP1 or in the case of two-channel devices select measuring
channel SP1 or SP2 .
5. Assign a binary input to the selected measuring channel: select Binary input x:y.
Controlling the measurement start time via an external signal
You can temporarily interrupt the automatic operation of the analyzer via an external signal
at the "DIO" module. You can also use this signal to specifically start individual measurements.
In this way, you can specify the time of the measurements using your external control system.
For this, connect the
Signal for process access to a binary input of the "DIO" module and set
the starting time of the measurements to Continuous . A measurement starts immediately as
soon as the signal at the binary input is active. The only exception is if a calibration or
cleaning is due on the basis of the set time intervals: in this case, these activities are
performed first of all and then the measurement follows immediately afterwards. If necessary,
