Instructions

HELP

Problem	Possible Cause	Solution
Signal fails to change to red	Dirty rail - especially steel rail Broken wire or loose wire	Clean rail with wire brush Check wiring - test board with link wire between L and SW terminals. If board works, trace wires and test rail connections.
Signal fails to return to green after train leaves section	Current leakage between the rails Metal swarf in section break	Check that the load bank bulb is working. Switch off the circuit then switch on - Goes to green then you are looking for low loss - swarf in section breaks, excessive water on sleepers etc. Reverts to red then you are looking at a section short or wire fault - see below.
Signal sticks on red	Wire fault (short) Rail/section short	As above + check if using override wire, this is not powered.
Bulbs are dim	Voltage drop Loose connections	A bulb at the end of a 30m wire is noticeably dimmer due to the resistance of wire. If possible feed power to signals in a central position. Check all connections are tight and dry. Wet connections can cause loss of power.
One bulb not lit	Bulb failure	Replace bulb
Both bulbs not working	Bulb failure Power failure	Replace bubls - both could have failed especially if the signal has been dropped Check power supply to the board/socket

Please Note

These signals are designed to run at 12v only
The method of train detection has worked well on our own railway. It is not totally fail safe and should be used with this point in mind.
All signalling set ups should be fully assessed before and during use.
The use of high voltage power in the garden is covered under the building regulations and needs to be carried out by a competent person.
Alway use a RCD for any high voltage (240v) cables that run in the garden
