Downstream from step controller

Contrac actuators can be driven using step controller pulses instead of an analog setpoint. The
following conditions must be fulfilled in order to implement the step controller pulses:
• Digital input function "Step controller" has been selected.
• The actuator must be switched to automatic mode (AUT) via digital input DI 1.
• AUT is activated via graphic user interface.
• MAN is not selected via the commissioning and service field (ISF) (software version 2.00 and
higher).
