I'm not familiar with the plugs you describe, but how about cutting off one of the unused pins and blocking up the corresponding hole. You would have to modify both plugs on different pins but even one would prevent getting them crossed over. Russell |

Yes Russell I'd thought of removing a socket and putting a customised peg in the corresponding plug, but the way it's wired all that will happen if someone gets it wrong is that the swarf conveyor will start instead of the pump, and vice versa. I also considered paining each plug/socket combination a different colour, but where do you stop ! |
| RussellT:
My idea was that if you cut off pin 1 on plug A and blocked hole 1 on socket A (eg by putting in the cut off pin) , then plug B couldn't be inserted as it would still have pin 1 and there'd be no hole for it to go in. If you did the same to pin 2 and hole 2 on plug B and socket B then plug A couldn't go in socket B. It'd be physically impossible to insert the plugs the wrong way around. Russell |

--- Quote from: awemawson on October 19, 2013, 09:37:14 AM --- I had bought a 'venturi mixer' to fill the coolant. A gizmo that fits on top of the 20 litre drum of concentrate, which it draws up using a venturi in the line from a tap. It incorporates a setting valve so that the correct ratio is mixed. All sounds a very good theory, and with 320 litres to mix for this machine seemed a good idea. --- End quote --- Eh? What's wrong with pouring the entire barrel of concentrate into the coolant tank, then adding the 300 (?) litres of water via a hosepipe (and, if you really must be accurate, via some barrels to measure). Once you've filled one 20ltr barrel with water (say, the now empty coolant concentrate barrel), you now know how long it takes to supply 20ltrs of water. So multiply up for the remaining 280, sit back & have a cuppa! Let the coolant pump do the hard work of mixing the stuff.... |
