Seacock warning device

[tangofour]

Ok, on the back of two threads here I have knocked up a little device for the boat. A sensor on the engine seacock detects when it is closed, it is wired into the engine ignition circuit, ignition on and seacock closed gives me an alarm and a flashing LED on the panel to stop me from running the donkey without cooling water.

I might repeat the excercise for the other 9 ( yes 9 ) seacocks aboard and run repeater LEDS on the panel so that I'm sure of the position that any one is in.

If the seacock is closed then it should disconnect the starter so you physically can't start the engines.

How about - in true PBO style - a wiring diagram for those of us less electrically minded?

Great I have designed an electrical operated seacock motor using a wiper motor which includes indicators to open and closed with interlock to what is connected to the seacock

On an electric heads both inlet and outlet seacocks must be open for it to operate.

On my engine and generator cooling water I also have flow switched which alarm if there is no water flow like "A closed seacock"

Personally, I prefer hydraulic valve actuators in an engine room.

What if you want to bleed the fuel system, by cranking with the seacock closed?

What you need is a 'Crank without cooling water' override switch with extra highly visible flashing light to ensure this is disabled once bleeding operation is over.

repeat the excercise

Will the toilet have a sitting down sensor or seat interlock with the seacocks to differentiate between having a pi55 (OK to open seacock after, to flush) and having a crap (need seacock open in advance so pumping can commence without delay)?

Re: repeat the excercise

Can you add to the diagram the wiring to run to a separate solar panel , charge controller, dedicated battery, CCTV, and integrated sensor for the SMS system to my mobile phone so that I can watch from the peacefulness of my office the whole confabulated issue opening and closing valves/seacocks, initiating the weight sensitive switch on the heads seat, interrogating the infra-red detector in the gas locker, operating the hydraulic tension self-regulating winches on the mooring warps, firing the anti-seagull perching spear on the masthead, working the automatic rain and spray sensors on the Kent clearview screen, and monitoring the bank of myriad LEDs on the control panel which will require a degree in Information Technology and the Semantics of Tells Tales / Indicators and Distributed Signalisation Systems BEFORE one opens the little can called "Common Sense" and just goes sailing ?
