Hi,
I'm pretty sure it has the sem controller in it (although I didn't look) I was there to do a different job and as I was leaving the operator mentioned it's always been slow since he worked there, maybe 10 years or so?
Definitely standard display because first thing I looked at when he mentioned it was the dash just to see if there was anything I could quickly change, I then popped the bonnet to see if it had a 2nd speed hydraulic switch but as I say there's no switches, just a pcb above the valve block and then I just left it at that and went onto the next job.
I think I'll be back there next month as their other truck is due a pmp so will do what you've suggested and take a bit more notice of what's fitted.
Thanks again, appreciate it
ok so no mode selection.
lets clarify something then, which controller does it have in it?
THE ev100LX or the sem sx controller?
both can be checked and set using ge sentry or a handset.
and does it have a premium display panel on it?
the difference between standard and premium is the premium is interactive with more options displayed along with performance modes, and the standard has just basic display functions. One will have 5 buttons on it, the standard will not, it will be just a basic display.
also the hydraulic, is that contactor controlled? or is there a 2nd controller for that mounted beside the traction controller? also another tell tell sign if it's premium or not.
Sounds like you have just a standard display.
now if you want to test that PCB control board on the hyd valve here is the test point layout:
TP1 battery neg P1-1 (P1 terminal)
TP2 battery pos P1-5
TP3 first function optical switch (lift) P1-6
TP4 first function optical switch (fast lift, not used with single speed lift pump) P1-7
TP5 second function optical switch (tilt) P1-8
TP6 third function optical switch (auxiliary#1) P1-9
TP7 fourth function optical switch (auxiliary #2) P1-10
Best i can tell from the table on testing the board your readings should be either greater than 3v when the switch is closed or less than 3v when it is opened.
Hi mate, thanks for reply.
Nah, she's an old girl, maybe 20+ years old, has a small pcb on the hydraulic levers which must read resistance as the levers are pushed/pulled back n forth
is this a new truck?
i've found generally when the trucks come from the factory they tend to have the speeds set slower than most folks like. I usually wind up changing the flow in the auxiliary hyd circuit so that the tilt and SS will go faster. You don't want to make it too fast because it will heat up the oil too fast and overheat the oil and/or hydraulic motor/pump.
The main relief valve pressure should be 2800psi and the auxiliary pressure should be 2250psi.
You'll need to put a tee fitting inline with the main hydraulic pressure hose to install a 5000psi guage and take the main pressure reading. If it needs adjustment the relief valve should be located on the main housing where the lift lever connects. As for the auxiliary hydraulic pressure the adjustment for that is on the tilt section. Both adjustment screws are an allen hex and may have a lock nut on them.
This is what i've usually found that causes the slow auxiliary speed.
If by chance it is a speed setting in the software first i would check the different mode settings, each one has different characteristics between the drive and hydraulic speeds mode 1 being the most conservative and mode 4 being the most aggressive. You might want to try this first before you do anything.
I believe the only way you will be able to change the mode characteristics is with pc service tool. You can also do it with a handset but that is more difficult, you'll need the full spec sheet including all the settings for the modes for that truck/controller, but it can be done.
