Handset MAC Address and S/N
The LT150A utilizes a matched pair of radios . the following two labels are the ad-
dresses and serial numbers of the locomotive unit and handset
If there is no label here , the same label/
information can be also found on the radio
tranceiver and the mounting side of the
Locomotive unit.
If there is no label here, the same informa-
tion can be found on the back of the
handset.
Contains FCC ID: MCQ-PROS2B
The enclosed device complies with Part 15 of the FCC Rules.
Operation is subject to the following conditions:
(i.) this device may not cause harmful interference and
(ii.) this device must accept any interference received,
including interference that may cause undesired operation.
WARNING
Radio Transmitting Device
This handset contains a low power “spread spectrum”
radio transmitter. While the e󰀨ective radiation of this
device is less than 200mW and though care has been
taken to design this handset such that the location of
the antenna minimizes human exposure to its 2.4GHz
energy, care should be taken to hold the handset per de-
sign to limit futher exposure and to improve operational
performance.

Charging the handset batteries
The handset can also be operated
with 2 regular AA Alkaline batteries.
However, the internal charger will only
work with rechargeable batteries.
WARNING: Do not attempt to use
the charger with alkaline batteries
installed!
+-
To charge the handset batteries, plug the
charger into the receptactle on the bottom
of the handset.
The LED on the front face of the handset
marked “charging” will indicate the charg-
ing mode and status. How the codes for
charging are read is described on page 8.

Charger LED indicator codes:
Code:
Pre charge state - 1 short ash per second
Rapid Charge - led is equally on/o󰀨 per sec
Post charge - led ashes short twice
No battery detected - 5 short pulses
Post charge constant voltage mode - 3

During charging, if the battery is deeply discharged, the charger will indi-
cate it is in a “pre-charge” state in which the battery voltage is brought up to
approximately .8V per cell before commencing rapid charge.
If the batterys are at .8V per cell or above, the charger will enter rapid
charge mode in which the batteries are charged at 500mA for a maximum
time of 5 hours
Please note: The charger will not start rapid charging the bat-
teries if they are still more than 50% charged.

1. Turn on the handset by pressing the power button for 2
seconds
2. Turn the Key switch on your locomotive to ON. Position.
3. The LT150 A will go through a startup sequence.
4. When all system checks are done and turn out OK, it will start
ashing the system LED indicator while the Master Relay led will
become lit solid
4.a The Locomotive Link symbol (on left of screen) will show up
5. press the brake button on the handset until the system LED
lights up solid . System, Master Relay and Radio link should be

Startup Error Messages:
These error messages appear if any of the system checks at startup return a
negative result.
The controller will check for battery voltage and motor drive/motor health, before
it unlocks the system for use
Low locomotive battery error:
Symptom: Solution:
Battery voltage shows 0 Check the wire and fuse for the battery monitors
Battery voltage is ~ 22V 24V sys Locomotive batteries need recharged.

4. System and Error Messages
User E-STOP:
This message shows when the power button is pressed while the
system is in operation.
It indicates that the locomotive entered the emergency stop state.
This can be cancelled with a push of the brake button.
Dropped handset E-STOP:
This message shows whenever the handset is dropped and been in
freefall for longer than the period specied in the setup menu. (“fall
time” page 17.)
Handset battery low warning:
This message shows whenever the batteries of the handset fall below
a charge voltage of 1.9v . This message is only shown for a short mo-
ment before the handset turns itself o󰀨. (safety shutdown)
Immediate recharging of the Handset batteries is adviced.
Overcurrent Warning:
The system triggers this message whenever the internal current limit of
approximately 175A is overstepped. This is a safety feature to prevent
damages to the motor or motor drive due to mechanical blockage or
overburdening of the locomotive.
Please note that the locomotive wont stop when this occurs, but the
internal safety will turn o󰀨 the drive on a per PWM cycle basis, and
limiting the current.
To dismiss this message you need to rotate the knob of the hand-
set a notch.
Overheat E-STOP:
The system triggers an Cycle STOP whenever the internal temperature
sensors measure a tamperature above the safe zone for the internal
components.
This message can not be dismissed until the locomotive and hand-
set have been power cycled
System cool down before further use is adviced!
User Induced E-STOP:
If you press the power button at any given time
the locomotive will go into an User requested
E-Stop. To cancel this you need to push the
brake - button once.

Changing direction: 1. press ‘forward’ to change the direction to forward
travel
2. press ‘reverse’ to change the direction to backward

Applying brakes: (With brake controller, or custom air-brakes installed)
1. Press and hold the brake button. Throttle will be au-
tomatically reduced to 0% and brake pressure applied
at the set value. (factory setting is 25psi)
2. Rotate the knob clockwise to increase pressure.
3. Rotate the knob counter clockwise to decrease pres-
sure.
Stopping/slow down:(Without brake controller)
1. Press the Brake button. Throttle will be reduced to 0%.
The four quadrant motor drive of the LT150A will slow
down the locomotive to a stop on an even surface.
if you are on an inclined track piece , the locomotive
might continue to slowly creep forward or backward
down the track. You can prevent this by giving a little
bit of throttle in the opposite direction of travel
Warning! This method is
only useful for short stops.
DON’T keep the locomotive
throttled up stationary on an
inclined track piece for too
long. It can cause heat dam-
age to your motors!!
