REGULATEURS EUROPA series hydraulic governors may be equipped with a speed setting device which can be adjusted from a
4-20 mA signal. In this instance the speed setting mechanism in the governor is adjusted by means of a stepper motor, which
is controlled by driver M602901F.

The unit complies with the requirements of IEC61000-4-2, -3, -4 and 5 if mounted in a steel plate enclosure. A potential free
change over contact is available for alarm indication. Please refer to the data sheet, which summarises the differences between
builds and provides the specification and connection diagram of the latest build M602901F.
