In DDC mode the actuating current of the controller is switched off at S66 = 1. The source for y

By OR linking of the digital output H with the control signal Si no computer standby or computer operation
can be signaled in manual or safety mode.

The control signal Follow up (N) has no function in DDC controllers. The tables apply for
S52 = 0 (with follow up of the inactive setpoint to the active setpoint). At S52 = 1 (without
follow-up) and x-tracking automatic operation starts with wi = x (xd = 0), the active setpoint runs
to the old set value wi via the possibly set setpoint ramp tS.
With the Shift key (12) the digital x display can be switched to the main controlled variable x1 in
the display level II. Signaling of the display levels takes place via the LEDs Control I/Control II
by a steady light.
