Chuff Control (cont)
Locomotive Loading Control
The locomotive power is monitored and filtered according to two CV’s.
a threshold determining the required locomotive power needed to play the power
chuff. Once the power level falls above or below the threshold, the chuff changes.
contains a filter coefficient determining the convergence time and accuracy in
measuring the locomotive’s power.
The locomotive power is substantially higher in DC mode. To compensate, a DC scalar
is provided at
. This scalar changes the thresholds of
, altering the power
load threshold providing proper chuff changes from power load changes in DC mode
of operation.
The locomotive power is substantially lower for N Gage locomotives. To compensate,
an N Gage scalar is provided at
. This scalar changes the thresholds of
altering the power load threshold providing proper chuff changes from power load
during operation.
Should the desired power thresholds need to be changed, a simple tuning method may
be used. Set
to 255. Now, thel power threshold is disabled. While running in
DCC, change
, lowering it until the chuff changes at the desired power load. DC
mode will require more work, since changing while running is not allowed.
Setting bit 1 in
will disable locomotive load power control.
