Control of
gorge dollop pump : the circuit with sensors and with impulse relays and timers
was already existing. There was a table next to the board of swithes and relays.
It was cannot be used without the table. It was in operation for about one
and half - two years, after that it was replaced by a PLC swithboard installing
by a contractor.
The switch
circuit below made in the AUER Édesipari Kft., where I was repairman in that
time. The problem of circuits made by alternative switches are probably well
known in the electrical craft. (I mean problem in mathematics of course.)
Because we did not learn much about it and I don't know writings in this subject
and it hardly ever has utility enough, certainly it is discovered again by a lot
of people who met such problems. Probably the first swith circuits made by
the first electricians, more than one hundred years ago. About the fact, that
such switch circuits exist I know from my earlyer colleague, Emil Balla
(mechanical engeener), who made one in his home. It is clean by his telling that
is such circuit. If such switch circuits may not fit nothing else, these may fit
to play a trick on electricians. (Please come and look after what is the
trouble, I have fitted up three switches, if this one is in this stand, and the
other two are in these, the forefront lamp is lighting, if I am switching over
this, the pantry lamp is lighting, if I switch over the middle one, the hall
lamp is lighting but the the other two lams not, etc.) I am not mathematican, by
my suspect the maximum outputs (number of possible positions) of these switch
circuits, if it may order more electrical studs with relays to every switch, are
the power of 2 where the exponent is the number of switches, that is eight in
case of three swiches. I know this last one surely, because the circuit below
also has three switches and would have had eight outputs, but there wasn't
needed so much. These circuits don't have serious utility, because they have
difficult wiring (complicated to looking over) and there is needed a table (with
a scheme) with the possible stands of swithes and with the outputs of each
switch stands. If it is figured out unlucky it may has "forbidden" combination,
too.
FE main
distribution board and the 1st and 2nd floor distribution boards ( FE1 and FE2 )
of a pantioner house. The original plan made by István Horváth electrical
designer. I comleted it with a difficult lighting control, with some outlets and
with overvoltage protection. The control of lighting would have been more simple
with automatic switches, these were installed only in the long corridors. Every
forth lamp was connected to the standby lighting circuits. The contractor was
the Energy System Bt. (later ESYS Kft.) The drawing FE-6-mod contents the
automatic switch operation. As I remember, there are such lighting operation on
the 1st and 2nd floor too, but these are not on the drawings. The K1 was not
a switching-off switch by my meaning, but the "0" position of it can be used for
switching-off. There was a fault in the original FE-6 drawing, that version can
switch off only the press-button control when K1 switch is on the "0" position.
I show you
some of my works below, where along the contraction I had to make electrical
drawings. There is one exeption there, the relay switch circuit of the haselnut
castor, that is not my work, but I made the drawing going after the wiring.
There are also one-linear switchboard schemes, these distributors did not
contract and installed by me, I only made the plans.
Also from the
AUER Kft. : control and driving of hazelnut castor. The relay switch circuit is
not my work, but I had to draw it, partly because I installed the inverter
(frequency control of the motor), partly because I had to supply the missing
drawings. The relay control starts the electrical engine of hazelnut castor for
every second impulse.
The boiler
swithboard in the same house. This plan designed by me.

temporary main disrtibution board ( for the building site ). The residual
current protection was in the connecting board.
