8.2.1 Auto / Manual Station (Low Signal Selection / Digital Signal Selection)
This template configures the ControlMaster as a back up for a Master Controller (system). In normal operation the
ControlMaster's current output follows the master controllers output value in Automatic mode.
Upon detection of a fault in the Master system, which is identified by either a low signal value on the Master Output or via a
digital Input signal, the ControlMaster selects Manual Mode with either the last valid Master Output value or a pre configured
fixed output value.
Once the Master signal is restored or the digital input state returns to its normal state the ControlMaster switches back to Auto
Mode and continues to follow the Master Controller output.
(See Fig. 8.4, page 105 for details of parallel connection).
