what is lockout exactly?

[David P]

Just been looking back through all the old posts to find out whats wrong with my potty puma 80 - and got thoroughly overloaded with info.

but i still have one simple question.
what exactly is lockout?

is it a designed state of the boiler workings, say to guard against some lethal eventuality.
or is it a term for a loop or sequence of fluid/events that prevent the boiler from doing what it should.

now i realise that the pedantic amongst you could equate one with the other - and I half expect to get a stupid answer to a stupid question.
but i would really like to know what lockout really is.

i have a potty puma, i have come up with the following conclusion.

Boiler must have a "variety" of saftey devices
If any "device" operates it goes into "lock out" mode so will not work.

Because potty wanted to keep costs down they have used a global "fault light" (ANY fault and the global fault light comes on) but they had to call it something, fault sounds like faulty, so you may think boiler is genuinely faulty, so you may want a new one, so they decided to call it lockout.

Looking at other boilers and on here other boilers (maybe some potty ones) have "error codes" each "error code" is dedicated to one / two things so you have a better chance of knowing what is wrong. Now to show an "error code" requires more electonics for the display and monitoring, so by having one single led, and calling it lockout you save pence / boiler, now multiply that by thousands, then compare it against another boiler makers prices.

That is my theory

Workers are so fed up making crap boilers for crap wages the management lock them out, called lockout.
