Stampa la paginaLED Indicators For Troubleshooting
Assuming you can see the little LED indicators on the CONVRTR-60 board, they will provide you
with some hints as to the causes of poor, erratic, or non-operation.
The PWR Green LED will always be on if power of the correct polarity is applied and turned on.
Even if the voltage is above or below normal, this LED will be on. If it is off, when you think it should
be on, check that the battery is charged, and verify correct wiring of the battery and switch. Make sure
the power switch is "On."
The GP Red LED offers several indications that can serve as an effective aid to troubleshooting.
Steady On: it says the throttle frequency matches the CONVRTR frequency.
Slow Blink: CONVRTR is in count down mode prior to entering Jump Mode. You must turn on a
throttle with a matching frequency to cancel Jump Mode. The GP LED will go dark after one
minute.
Dark: there is no throttle present that matches the CONVRTR frequency setting and it has now
entered Jump Mode. To cancel this mode, power cycle the CONVRTR and make sure the throttle is
set to the CONVRTR's frequency.
Erratic blinking on and off: the throttle is set to a power level that is too low or the throttle is too far
away or both.
Troubleshooting Tips
Train Stops When It Is Far Away - This is an easy one. You need to set the decoder's loss of signal
timer, set CV11 to a value of 0. Any other value and the locomotive will come to a halt when the
throttle signal is gone and the timer has expired.
Throttle Loses Control When Locomotive Is Far Away - This is just the normal limitation of the
radio system. Do not expect the throttle to control the train when it is a thousand yards away. However,
if your railroad is in a large loop, then leave the throttle on its original setting and let the train come
back to you.
Horn/whistle Won't Stay On When F2 is Pushed And Held - This is usually caused by a
combination of noisy motors and distant operation and is not actually a problem. Instead, it is an
automatic feature of the CONVRTR-60. If for any reason, the CONVRTR-60 stops receiving throttle
commands, and the last command was horn ON, then it will automatically issue a horn OFF command
after a preset amount of time.
Limited Reception Range - There are many causes that contribute to shorter than expected range. In
no particular order, here's a list of items known to impact the range.
Antenna parallel to motor or battery wiring: Keep all wiring away from the antenna.
Metal shell: If loco has a metal shell, the antenna must be outside of the metal shell.
Noisy motor: Consider remotoring with a low current, high efficiency motor. Not only will the range
be better but the battery will last much longer.
LOCO Runs If Throttle Is OFF
This is easily solved since it is the decoder causing this. The decoder must have the analog conversion
turned off. To do this, program the decoder's CV29 to a value of 2 if the loco address is between 1 and
99. For loco addresses higher than 99, program the decoder's CV29 to a value of 34. These values turn
off the analog conversion.
The troubleshooting list below assumes that the CONVRTR has been properly installed and was
working OK. The bold face type is the symptom.Common causes are described with the most
common listed first and the least common listed last.
Any condition that trips the CONVRTR's self protection will require a power cycle to reset it. In
other words, turn off power to the CONVRTR and then turn it back on.

Recommended Soldering Tools and Solder
Soldering small wire is not difficult. However, if you don't have the correct tools, proper soldering
is difficult and frustrating.
Use Small Diameter Rosin Core Solder. The choice of solder is also important. One of the things
to remember is to never use acid core solder. Acid core solder will destroy the board and
components. The best solder for electronics work is small diameter, 0.015 to 0.02 inch "no-clean-
flux" core solder. Larger diameter solder should not be used as there is a risk of putting too much
solder on the pad which will short out adjacent pads.
Use A Small Diameter Soldering Iron. Do not use so-called soldering guns. These are very high
wattage and will damage delicate traces, pads and components. A 60 watt, temperature controlled
iron is the best.
Tool Source: The following part numbers and prices are from Mouser Electronics
www.mouser.com. They are an excellent supplier that we use as often as we use Digikey.

Soldering Iron Stand and Sponge Holder
60/40 Rosin Core Solder Roll
Keep The Soldering Tip Clean. Buy an inexpensive soldering iron stand, that includes a holder for
a small sponge. Keep the sponge damp. Swipe the tip across the damp sponge to clean it before
soldering. Don't clean after soldering - the excess solder protects the tip. Before turning off the
iron's power, put a blob of solder onto the tip. This solder coats the tip and prevents oxidation.
Always Twist and Tin Stranded Wires Before Using. Stranded wire must have their individual
strands twisted together followed by applying a small amount of solder - this is called tinning. It
makes soldering the wire to the board much easier.
Soldering Tips
Do Not use too much solder. A tiny amount is all that is needed.
Never apply the solder directly to the iron and attempt to 'paint' it onto the lead.
Proper soldering takes a little patience. This is the most important part of learning to solder.
You must watch and wait if you want to have a good solder joint. Soldering can not be rushed.
When the joint has cooled, trim the excess lead using the wire cutters. Do not cut off the solder
joint - rather trim the lead to the top of the joint.
Hookup Wire and Heatshrink Tubing Source
To avoid confusion and possible damage, always use different colored wires for hookup.
Standardize on what each color does. Take a few minutes to document your installation. Make a
record of the colors used and take pictures of your installation. You might remember what you did a
month from now. But what will you remember a year from now?
The suggested hookup wire comes in 100 foot rolls. This wire is
More important is the thin outer insulation. Share the cost of this wire among friends - the roll will
last a long time
