2. The cleaning trigger is transferred to another device via a binary output. This does
not have its own connected cleaning unit, but its sensors are installed in the medium
affected by cleaning the master and are set to hold by the trigger.
3. The trigger is transferred via an additional binary output to another device, whose
connected sensors have their own cleaning units. The signal can be used to
simultaneously activate a self-cleaning with the master.
Interrupting the operation via an external signal
You can temporarily interrupt the automatic operation of the analyzer via an external
signal at the "DIO" module. This can be useful if no sample is available in your process at
certain times, e.g. during a cleaning phase.
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.

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.
