F40PH Diesel Operating Manual
I cant get the engine to run after I power up the transformer. It sits still with the diesel
compressor sounds running.
The engine is locked out into the Neutral position. Follow the unlocking proceedures in
the Lockout Section.
The engine wont lock out into Forward, Neutral or Reverse even after the short horn
blast sounds.
You are waiting too long to turn the throttle back on after the short horn blast sounds.
The power must be turned back on immediately after the short horn blast sounds or the
engine will go back into RESET. See the lockout proceedure in the Lockout Section.
VOLUME PROBLEMS
REMEDY
When I try to run the engine, the diesel volume is OFF or very low.
The diesel volume has been programmed at a reduced volume or to be silent. Go to
RESET Feature 6 and adjust the volume. See the section entitled Using RESET to
Program ProtoSounds for more information.
When I try to set the diesel volume, it resets itself to the original volume after I selected
the new volume.
You are trying to set the volume with a poorly charged or dead backup battery. See the
section on Battery Backup for more information.
When I try to set the Diesel Volume to O Volume, I still hear the cab chatter sounds.
When the diesel volume is set to O, you will hear the Cab Chatter sounds because
setting the diesel volume only controls the sound of the diesel engine itself. All other
sounds, including Cab Chatter, the horn and bell will continue to play at the volume level
set by the manual volume control knob located on the bottom of the chassis. See the
section entitled ProtoSound Volume Adjustment for more information.
The sounds seem distorted, especially when the whistle or bell is activated.
The overall ProtoSound volume has been set to high creating the distorted sounds. Try
turning the volume control knob located on the bottom of the chassis counter clockwise to
reduce the overall volume level.
BATTERY PROBLEMS
REMEDY
I get no sounds when the engine shifts between the direction states.
The battery may be dead or needs charging. See the Battery Backup section for more
information.
After I turn off my transformer, my engine continues to make sounds before quitting with
a ding of its bell.
ProtoSounds continues to sound for approximately 10 seconds after power to the track
has been shut off.
The sounds distort at low voltages.
The battery is insufficiently charged or dead. Follow the recharging instructions found in
the section entitled Self Recharging Battery Backup System.
A repeating horn blast occurs after the power has been shut down.
The battery is insufficiently charged or dead. Follow the recharging instructions found in
the section entitled Self Recharging Battery Backup System.
RESET PROBLEMS
REMEDY
When I first turn the power on, the engine will not begin to run. I have to turn the throttle
off and then on again to get the engine to operate.
This is normal behavior. When power to the track is first turned on, ProtoSounds enters
a RESET phase at which time the engine undergoes a system check. Power must be
interrupted to get the engine into the Forward Phase. See the section entitled DCRU
Reverse Unit Operation for more information.
Whenever I interrupt the power from RESET to enter Forward, the engine goes back
into RESET instead of Forward. I know this occurs because the bell dings twice.
Whenever ProtoSounds enters RESET after power has been off for more than 15
seconds, the microprocessor initiates a system check to determine that everything is in
working order. This system check requires 2.2 seconds to complete during which time the
engine will play the diesel startup sounds. We recommend that you dont interrupt the
power in RESET until the diesel startup sounds have completed. This will guarantee that
the system check will have been completed since the startup sounds take longer than 2.2
seconds to play. If the problem persists, we recommend that you operate the throttle with a
slower movement as you interrupt the power in RESET and enter the Forwaard Phase
