Welfare cabin hydraulics

[V8Druid]

OK .. it's reverse to what i assumed ... can't understand why the LED is changing colour, unless it's due to voltage drop at that DIN connection ... try energising the cetop coil and crossing the starter poles to run the motor ... there'll almost certainly be a relay to operate the solenoid on the motor -- too high a draw for a small push button - usually ... (much like an ignition relay on a vehicle operates the starter solenoid) ... will almost certainly be two relays to operate solenoid on motor - one for the up motion and one for the down motion .... cetop solenoid'll only be circa 1A draw so probably paralleled with motor solenoid's relay?

correction ... assuming your "press it down" in the vid means legs down my assumptions are correct, but that said .... your "press it up" is running the pump motor so do you mean "up" is lift cabin up???? bit confused

No down is retract rams cabin sits on floor

Up is cabin goes up rams extend pump runs

my money is on a faulty relay, operating/controlling the pump motor's solenoid, in parallel with the cetop's solenoid activation

Lots to check out tomorrow

by coincidence these came up in my email this morning @Giles .... these however use a double solenoid cetop to reverse the flow

Has he fixed it yet??

looks to be an all ports closed set up Mike ...

should self level by equal pressure to all rams ... if all in parallel no ram will take more pressure than any other

Doesn't stop there though spring will push it straight to parallel port

Yes it was haha populated it today for next two Jobs which are all drainage, annoyingly it’s 12’2” with square feet so doesn’t fit snuggly on my two 12’ trailers. Need to weld some lifting eyes on it so can lift it with diggers when no forks available

Giles. Does this mean you will be needing some manhole covers. I happen to know where there are some

I read that as sprung to stopped ports, but was at a loss to decide what would put the shuttle at parallel ports, other than oil pressure Mike

But that would be identified by a pilot symbol

Good to know if anything worse happens it’s not too bad to replace

No not been to yard today got delayed in a meeting that was 2 hours longer than it needed to be
