Basic Kit  is without points or signals boards. CDU comes free with the first points board

 

Installation Tips and operating help

Checkpoints :- 

These are reed switches that are normally open. They can be connected either way round and 

simply diasy-chain  in parallel and connect back to the main controller. 

A simple way to test them is to select A (record) on the hand held and after the 2 pips just wave a magnet 

over the checkpoint to see if it beeps. Dont worry if you get a double beep. 

 

Points control :-

You need one points board per turnout. - We are planning a twin board, rather like the twin signals board, for the future.

Only solenoid points are supported at present. A servo version is being developed.

 

Notes about PWM - a note of caution!

The system uses Pulse Width Modulation (PWM) at a frequency of around 10Khz. 

This is fine for the vast majority of DC Locos but some may be fitted with a spark suppression capacitor across the motor.

If so, then at medium to low speed it acts as an AC current path and draws unnecessary current and if its value is greater than 1uF  might get warm or hot.

It is best to remove the capacitor, but this is only necessary if the value is 1uF or greater. If its marked 0.1 or 0.22  or 0.47 then thats ok.

Newer locos that are DCC ready have a 10uF cap fitted and our electronics will detect this and emit a continuous beeeeep to remind you to remove it. 

MR Innovations Ltd takes no responsibility for any issues arising from the non-removal of capacitors across the motor of DC locos.

If your loco runs smoothly then you are probably fine, a good test is to run at about 1/3rd full speed for 2 to 3 minutes and then feel the 

loco to see if its overly warm. If so then open up the loco and snip one leg of the supression capacitor.
