7. Disturbance variable : in the controller menu, select the binary input to which you
have connected the flow measured value. ( Menu / Additional functions / Controllers /
Controller 1 / Disturbance variable / Source of data = Binary input 6:2 and
Measured value = PFM value )
8. You can activate a dosing pump through PFM via a digital output of the DIO module.
Connect the pump to an output of the DIO module (e.g. slot 6, port 1) and select the
following settings in the menu: Menu / Outputs / Binary output 6:1 / Signal type =
PFM and Source of data = Controller 1 .
Take the direction of action of your dosing into account. Select the correct parameter
( Actuator type = U or Unipolar- ).
You must make additional settings in the controller menu to fully customize the control to
suit your process conditions.

 63 Example of a central cleaning control
1 External cleaning trigger at the binary input
2 Transferring the external hold over binary output to other measuring devices without connected cleaning
functions
3 Transferring the cleaning trigger over a binary output to other self-cleaning measuring points
1. An external trigger actuates a cleaning operation at the master.
A cleaning unit is connected via a relay or a binary output, for example.
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.
