Utilize the advantage of the effectively wear-free control with binary outputs versus a
control system with relay. With pulse frequency modulation (PFM), it is possible to achieve
virtually continuous dosing using a dosing pump with higher input frequency.
1. Connect the INS proximity switch of the CCA250 assembly to a digital input of the
DIO module (e.g. slot 6, port 1).
2. In the software, configure a controller and as the source select the binary input
(e.g. Binary input 1 ) to which the proximity switch is connected. ( Menu / Additional
functions / Controllers / Controller 1 / Controller Enable = Binary input 1 )
3. Signal type : For the selected input, select the factory setting ( Static signal ).
4. Connect the measured value of a flowmeter to the second input of the DIO module
(e.g. slot 6, port 2).
5. Signal type : for this input, select PFM . ( Menu / Inputs / Binary input 6:2 / Signal
type = PFM )
6. Input variable : select the corresponding measured value ( Flow rate ).
 You can now use the input you have just configured as the disturbance variable
for your controller
2)
.
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.

 71 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) An activation code, Order No. 71211288, is necessary for the "feedforward control" function.
