Dear All,
I have a problem with my Linde L16 S/N: W4X372U04484 year 2007, the problem is when lowering the fork, its very slow, almost not lowering.
Lifting is good, traction and steering also good.
i check with LTD, in LLC27 there is NO error code, lift Parameter in window7 of LTD is:
vFDn :0.36
PrVa :0.64
PS1p :0.030
Ipwm :0.75
when i lowering the potentiometer, and i check window5 of LTD (valve and contactor output), i got:
x02: pulse ratio proportional valve is 640,
thats mean this proportional valve suppos to be open around 60% and the output voltage should be 14.4 vdc
but when i check the actual voltage on proportional valve for lowering is only 2,8 vdc. so the fork lowering is very slow.
Can anyone help me please?
i already tried to replace all hydraulic device (hydraulic pump, controlvalve, solenoide valve, coil) but still can't solved the problem.
i need your advice please...
