DCU Pickup Pulses Per Revolution
If there is a pickup connected to the DCU, or “DCU” is selected among the sources above,
then set the flywheel teeth count here.
General Configuration
RPM Rounding
rounds off the displayed value to nearest 1, 5 or 10 RPM.
Run Setpoint
is the RPM at which the DCU indicates the engine is running.
There are also four additional
RPM Setpoints
that can be used as input to event handling.
RPM Ready to take Load
is a signal that can be configured to an output relay. It activates
when that RPM is reached. It deactivates when a stop command is given, OR the speed
drops below the threshold minus 15%.
RPM Nominal Speed
is the engines nominal speed, and is used to calculate the overspeed
setpoint and RPM overspeed test setpoints.
General
Configures how the channel is used.
Display
Configure how the channel is displayed on the panels.
Overspeed
RPM Overspeed
is the setpoint where the DCU indicates overspeed.
RPM Overspeed Delay
is the delay – in milliseconds – before shutdown. Typical setpoint is
100ms.
RPM Overspeed Shutdown Enabled
is where the overspeed behaviour is selected.
Select Yes for the DCU to shutdown the engine. Select No to disable overspeed shutdown.
Disabling DCU overspeed is valid for the DCU only. The SDU is able to shutdown
the engine.
