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, 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.
