Keenan weigh box

[Pistonbroke]

Have a digistar 2000 box on the Keenan and it's developed a mind of its own. Turned it on and it was showing "19500 kg overload". Zeroed the clock and the weight was going up and down just parked. Disconnected the weigh bars and still doing it so I've ruled them and wiring out. Anything I can do,or is it a david king job,or how much to replace?

Take the box off and put it into the house hotpress. Damp can make it do funny things

I'd be surprised if water is the cause,it's always indoors and the box is covered well anyway but it's worth a try

Our '05 Keenan started mucking about with weights 18 months ago or more, always in the shed, never left out.
Spoke with the guy who looks after it for us as he said weigh cells had gone dry- put some diesel around them.
So every time we grease the machine now, we have some diesel in a fairy liquid bottle and just squirt a bit around the center join of each weigh bar (doesn't need much!).
Havent had a problem since !

If I zero the clock with no weigh bars connected,just power,the clock is going up slowly. Gets to 350kg in about fifteen minutes

Our keenan weigher is playing up too. When you turn it on in a morning it will read somewhere around 85kg, then slowly count down over 10/15 mins. After that its fine. If you zero it straiggt away it counts down to -85kg. Took the insides out and had it by the aga for a day, still no difference. Tried the box of a neighbours keenan and its fine, so definately the box. David king was going to be my next port of call.

All the problems described above will 99% be a dodgy weigh cell

Spoke to them this morning and an engineer is ringing back

But why when the weigh cells aren't connected up?

Gave up with mine years ago , Keenan weighers are utter junk just a cash cow for them , I use the weigher in the forklift never let me down yet,

Had a problem with counting up or down quite quickly....it was a mouse or rat had chewed a weigh cell wire, exposing the wires and dampnes/rain had got in. Check the plugs haven't got dampness in and around them too.....they work on milliamps...

Dampness on your fingers will affect them on an exposed wire

i would try replacing the cable from the weigh display down to the junction box, the cable goes brittle and lets dampness in

Could be. David King engineer has given me some tests to do when not lambing. He thinks it could be the socket coming out of the box but I haven't had a chance yet
