Liquiline System CA80SI Operation
Endress+Hauser 75
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:
– Signal Measurement active: Indicates that a measurement is currently running. The
signal is not active in the event of a calibration or cleaning.
– Signal Sample required: 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, go to Menu/Setup/Analyzer/Measurement and select as the
start condition Continuous (analyzer measures continuously, without interruption,
between the measurements).
2. Menu/Setup/Inputs/Binary input Select x:y.
3. Configure the binary inputs as follows:
