The controller is accepting manual controll of breakers and other controlled
components when the Emerg. manual is active. It deactivates all outputs.
This function is also used in case of
redundancy
to disable redundant
controller.
Controller opens following binary inputs (or if already opened these outputs
stay inactive):

The output terminals that are configured with inversion are closed. Voltage,
current and power measurement is active all the time, regardless of the
actual state of the mains. It is possible to influence breaker under IM-NT
supervision without Wrn MCB fail or Wrn MGCB fail.
After the binary input EMERG. MANUAL is open again, the controller
recovers to the previous mode and behaves according to the actual situation.
Function is active in any controller mode and activation of this input is written
to history.

:
The function is intended especially for Marine gen-sets which are supposed
to be started manually while the controller has no power supply. To recover
successfully from this state, only the signals MCB ON/OFF coil should be
used for mains and breaker control, as the other outputs are continuously
active during Mains operation and it is not possible to switch them between
more control sources.
