11.12. 0-10V/PWM
Max. 2(3) 0-10V/PWM outputs can be activated in the controller.
The following explanation describes conversion from an internal normalised value (e.g. speed of rotation) to
a 0..10V/PWM output.
The control assumes a normalised parameter in percent (speed of rotation, output, 0..10V). This is output on
the allocated output as a PWM signal or 0..10V voltage.
It is assumed that limits, where required, will be made in the outputting function. E.g. the reference value is
limited to 45 °C downloads or the speed of rotation of the main pump is limited to 30%.
Control PWM
The 0-10V/PWM output must be allocated and configured as PWM. If the function is inactive, the output must be
configured to "not allocated".
The input parameter (%) his output one-to-one. That means 75% is output as PWM with a mark-to-space ratio
of 3 to 1:
Using the "Configuration output" parameter, it is possible for the signal to be output inverted as well:
Control 0 .. 10 V
The output must be allocated and configured as 0..10 V. If the function is inactive, the output must be configured
to "not allocated".
The input parameter (%) is converted into a voltage using a linear characteristic (according to the set
characteristic) and applied to the output. The characteristic is determined by the 2 point pairs {X

It is limited downwards to the switch-off voltage (U

) and upwards to 10 V.
