connect the Measurement active to a binary output to identify when the measurement
actually begins. If you do not require any more measurements once the first measurement is
finished, you have to already disable the Signal for process access during the active
measurement.
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.
1. For the measurement, under Menu / Setup / Analyzer / Measurement select Continuous
as the start condition (analyzer measures continuously, without interruption, between
the measurements).
2. Select Menu / Setup / Inputs / Binary input x:y.
3. Configure the binary inputs as follows:
