De-rated P Term -
This code provided for t)1e
P(Proportional) Term, in the speed PID controi, to be de-
rated right after start-up for a short period of time. This
allows the engine to warm up with out havil).g aq aggressive
P value which could cause "hunting" or instability when the
engine is cold. On some older units there is also a trim pot on
the top on the EUC that can manually de-rate the P value.
This will be reflected in this box.
Speed P, I & D Terms -
These values reflect the engine
speed governing process. These values are constantly
changing and it is very hard to get any information from
them. The only thing I can say on the subject is that you
should see these values constantly changing. If for some
reason there are all zeroes in these columns than the engine
is probably not running.
EMISSIONS RECORDS DISPLAY

When the engine has been running properly, Normal
Conditions will appear in the Emissions Records Display. If
there are no conditions recorded, the message There are no
emissions records to display will appear. This should only
display when the engine has never been run or the ECU has .
been replaced.

The engine must be in
th~
Idle state with the main DC
circuit breaker ON for this function to work.
Clear the Display
Pressing this button will clear the Emissions records Display

the ECU. This function works with the engine running or in
Idle mode as long as the main DC circuit breaker is on.

the DC circuit breaker is used to
shutdown the Genset, no Emissions Record will be logged.
