Function of dipswitches for operation as Speed controller
1.01
(DIP 1 =
|
OFF
|
)
For operation as a speed controller (main switch = Auto), the output voltage is set manually by
adjusting the built-in potentiometer, by an external potentiometer or external signal.
The desired function is determined with dipswitch
S1

,
4.01
(DIP 1 =
|
ON
|
)
For operation as a P-controller, PI-Controller (main switch = Auto) the actual value measured by the
sensor is compared with the nominal value that has been set. The output voltage and hence the
rotational speed of the connected motor automatically change as a function of the parameter settings.
The desired function is determined with dipswitch
S1
