Manual Operation
•
The PCB LED and lights turn off as soon as
I turn on the RailBoss ...
The RailBoss is shutting down due to
low battery voltage (less than 3.0 volts
per cell).
Recharge or replace the traction battery.
Disable or reprogram the Low Voltage
Warning parameter (6) for the proper
battery size. In order to do this, you will
need to enter the User Programming
mode right after power-up, before the
LED goes out. Set parameter 6 for Op-
tion 1 (disabled), or the proper voltage
for your battery pack.
•
Nothing seems to be working
Pressing any button on the transmitter
should cause the RailBoss LED to blink
off. If not, check the transmitter battery.
It should be 2.5V or greater (3.0V for a
new battery).
Check the power. The RailBoss LED
should be ON. You should measure be-
tween 7 and 25 volts DC applied to ter-
minals B+, B- .
You should measure 3.2 volts DC on
terminals 14(+), 15(-)
Verify all wiring connections.
•
The transmitter doesn't work at all.
Did the receiver successfully “Learn” the transmitter?
Open the transmitter case and make sure the battery and radio module are full seated.
The battery should measure at least 2.8 volts (3.0 volts nominal).
Replace the battery with a CR2032 coin cell battery.
•
Erratic throttle behavior? Reset throttle to default full range values using throttle programming procedure (See
Throttle Programming).
•
The loco doesn’t start moving until I hold the Faster button for a long time.
The voltage is ramping from 0 volts to that required to move the loco. You can eliminate this dead time by
programming the Min Speed setting to a higher value. (See Throttle Programming).
•
The loco starts moving as soon as I turn it on.
Program the Min Speed setting to a lower value.
•
The locos runs in reverse at power up, even though the front light is ON.
Reverse the wires at the motor output, terminals M+ & M- .
Check setting for Direction Control parameter 5.
•
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 or the Max Speed setting. You need more cells/
voltage or you may need to restore the default throttle programming settings.

RailBoss 4 Transmitter
With Out 3/4 on the Right
(Older models)
Out 3/4 on the Right is the original label configuration.
You may now choose which side you want the Out 3/4
functions to operate on via User Programming Parameter
9. (but the label may read wrong).
