Trouble Shooting Manual Operation
•
Nothing seems to be working
Check the power. The LED should be flashing a “heartbeat”. You should measure between 7 and 25 volts
DC applied to terminals B+ (18), B- (19).
You should measure 5 volts DC on terminals 1(+), 5(-)
Verify all wiring connections.
Repeat the “Binding” process for the transmitter and receiver. The Receiver LED should come on a few
seconds (2-20 secs) after turning on the transmitter.
•
Did you successfully do the throttle calibration procedure on page 9? Do it again. This step alone will
solve most problems.
•
Erratic throttle behavior? Reset throttle to default values using throttle programming command 5
(page 22)
•
My locomotive just quits, then it will start working again after awhile.
The control board may be overheating; especially if it is a hot day and your battery voltage is greater than
about 15 volts. Increase ventilation to the control board, or reduce your battery voltage, if possible.
•
The transmitter / receiver doesn't work at all
Check the batteries in the transmitter.
Check the receiver wiring: A connector may be backwards or plugged into the wrong place. The white
wires should be towards the inside of the receiver.
Did you successfully bind the receiver to the transmitter?
•
One or more of the control sticks work backwards ...
Make sure the transmitter servo reversing switches are all set for “Normal”.
•
The loco doesn’t start moving until I move the throttle stick way off the bottom ...
Recalibrate the throttle stick.
Program the Min Speed setting to a higher value.
•
The loco starts moving even though I have the throttle stick at full down ...
Program the Min Speed setting to a lower value.
•
The direction commands are backwards ...
Reverse the wires at the motor output, terminals M+ (20) & M- (21).
Make sure the transmitter servo reversing switches are all set for “Normal”.
Change the Motor Polarity using the Throttle Programming Command (4).
•
The loco won’t run as fast as I like even though I keep trying to increase the speed setting
Maximum speed is determined by your battery voltage. You need more cells/voltage.
You may need to restore the default throttle programming settings (page 21).
•
The speed setting seems to be changing on me...
The “Speed Setting” is actually a “% of battery voltage setting”. Hence, as the battery voltage decreases
during discharge, the speed will slow down some. Also, changes in load, such as adding more rolling
stock to the train, will decrease speed slight.
•
I can’t get full throttle ...
The throttle programming function has a “Max Speed” function. This may need to be reset. See page 20.
•
The PCB LED and lights turn off as soon as I turn on the transmitter ...
The RailBoss is shutting down due to low battery voltage. Disable or reprogram the Low Voltage Warning
parameter (6) for the proper battery size.
