Input
This lists the input status on DCU
terminal 86 to 97.
If for instance DCU terminal 89 is
measured to 24V, but the
troubleshooting screen for that
channel indicates ‘Inactive’, then that
input channel is faulty.
Run Sources
A number of different sources can be
configured to indicate for the DCU that
the engine is running.
This page indicates which source is
giving the DCU a running engine
indication.
Button Test
This option makes it possible to test
that all DCU buttons work.
To leave the test, press and hold
button Func 2, then press button Func
4.
