Wiring example
Figure 7.11 Fast load-reduction using a thruster controller
The thruster controller can reduce the load by reducing the frequency of a frequency drive. Alternatively, the thruster controller could
change the propeller pitch.
Inputs and outputs
Assign one of the following output functions under Configure > Input/output. Select the hardware module, then select an output to

Configure this output with a suitable scale. The output can be
an input for a load controller, for fast load-reduction when the
available power is low.

INFO
Use PMS P avail. to ensure that there is power available from GENSET controllers in AUTO mode. Use Conn. P avail. to
include the GENSET controllers in SEMI mode and any controllers under switchboard control in the available power.
7.7.6 Protections
More information
See Power management, Power management alarms, Heavy consumer reservation not possible and Heavy
consumer feedback timeout for more information about the power management protections for heavy consumers.
7.8 Externally controlled breakers
7.8.1 Externally controlled bus tie breaker
The externally controlled bus tie breaker function allows an externally controlled bus tie breaker to be present. This breaker is
opened or closed by the operator. The DEIF controllers only receive position feedback from the breaker, and do not control it.
