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.

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.
NOTE:
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
window only. It will not clear the records that are stored in
the
ECU. This function works with the engine running or
in
Idle mode
as
long
as
the main
DC
circuit breaker
is
on.
NOTE:
It is ve1y important to use the START/STOP switch
to stop
the
Gen.~et.
If the
DC
circuit breaker is used to
shutdown the Genset, no Emissions Record will be logged.
