The third mode causes the turbine to drop to idle before the dynamic brakes
are activated. To enable this mode, add a value 128 to the base value in CV
116.
CV 116 Example:
You want to use automatic notching with an increase
for every eight speed steps. From the section under ‘Engine Control’, we
determine the base setting for CV 116 to be 8. Then to enable Auto-Start, we
add 32. Thus, CV 116 is set to: CV 116 = 8 + 32 = 40
If we then determine that we want our Dynamic Brakes to come on at Turbine
Idle, add 128, thus making the correct value for CV 116 = 168.
The default value of 39 for CV 116 enables automatic engine notching at
speed step 7, Auto-Start enabled and Dynamic Brakes active on Function 4.
CV 199 Turbine Start Speed
Setting CV 199 sets the speed step where the turbine will turn on when using
the Automatic Engine Notching mode. It also sets the maximum motor speed
step when the Interlock Bit is set (Bit 4, CV 116). The default value is speed
step 7 between 0 and 127.
CV 200 Turbine Timeout
Setting CV 200 selects one of two modes of operation. Semi-automatic
mode allows the prime mover sound to be manually turned on using Function
9 and turned off using Function 10, though engine notching remains in
Automatic Engine Notching mode as set in CV 116. This mode is activated
by setting CV 200 to a value of 0.
The second mode of operation sets the number of seconds (from 1 to 255)
that it takes before the turbine will turn off in Automatic Engine Notching
Mode (CV 116) once the the locomotive reaches speed step 0 and no
functions are left turned on. Example: Your engine has Automatic Engine
Notching enabled and a value of 25 programmed into CV 200.. Once the
locomotive comes to a stop, and all your functions are turned off, it will take
25 seconds for the turbine to shut off.
