iDrive Unit (motor control unit)
We have various options of programming with the iDrive.
Auxiliary socket 1 is programmed to supply 24v dc (3 amp protected) when the engine is put in
reverse) as standard. On request we can supply Aux 1 for use with an electronic brake with slight
delay to avoid roll back when setting off. Call if you would like custom programming.
The idrive unit has been programmed by Ride on Railways. The unit is factory sealed and contains
no user serviceable parts. Do not open the unit as it will invalidate the manufacturer guarantee and
may affect how the company deals with a repair.
The Truecharge Meter not only acts as a basic battery condition meter but a fault reporter. If the
unit flashes up a code please use the chart below to identify the fault. If the unit is flashing and the
engine does not power up, take note of the fault before switching off the ignition switch. If the unit
fails to reset please contact Ride on Railways.
Do not worry if you do not get all the green lights lit up on the meter. It meter is only a basic guide
to battery condition and works on the assumption that when batteries are running low the voltage
drops. Some batteries can give out a slightly lower voltage yet still have good capacity.
If in doubt check batteries with a load bank tester.
Regenerative Braking
Regenerative braking is when the motors are used to generate electricity which is then put back in
to the batteries. For short light weight trains the power saving advantage is minimal but having a
loco which will bring a loaded train to a halt is a great advantage.
The braking is so effective that on hard braking you may even get wheel slippage on the engine.
Braking is progressive
–
“the faster you shut the controller down the harder the braking will be”
The controller also has an emergency stop feature which means at full shut down the controller
will put power to the motors to achieve maximum braking. Try to avoid unless necessary.
