I presume you are aware of this nice solution to take a normal relay, get the right base and one can turn it into a timer…
Well, one day I get a call:
None of these stupid things work and the @$%$#$#5^, they are rubbish…
Whilst he is throwing a tantrum I pull out the little manual to see who this culprit is because I know there cannot be multiple failures on one product.
This timer module has a start terminal which he needs to use…He says he connects it to the start terminals and nothing happens.
I look at the drawing and I say but it is not a start terminal it is terminal “B”. that requires power.
Huh, what terminal “B”?
Ok. Do me a favour…power down everything take a normal short wire from A1 and short it to B then switch on – we are going to test (but don’t get shocked)…
Sure as hell, he touches the wire to terminal “B” and there the thing works…enlightenment.
As I am, cannot resist figuring out what is the bottom-line of his problem…
I ask the question:- Then where is this terminal ” B” – it is not on the socket / base as expected…
The base has a terminal marked START so…See pic
I guess Finders thinking was to provide a terminal to power the start signal from (and they shorted START with A1 terminal – same terminal) and one is supposed to use this supply to go via whatever you use to trigger(series), and come back to the timer “B” terminal which sits on the timer module. (See pic)
One can easily mistake the terminal marked START on the base to trigger the timer though…I don’t blame this customer!
