vector displays prox-rpm error  can someone help me with this

have u checked with the free mech. help on this site?

left  message waiting for his reply

will the rpms come up at all? if not check your clutch pedal hanging just a hair or the switch prox switch on your clutch pedal. if triggered it will not let the rpms come up the computer will think its a fault

comes up on display as pto is not engaged  prox-rpm problem,,have no functions on remote at all .  rpm will increase using cruise on truck .it is a 2007 schwing 34m that was just bought, we never used it since it arrived last week,there seems to be a switch or sensor on transfer case missing ,cause wiring plug ends there and there is a bracket there with 2 bolt holes in it.

No offense but when you asked about the conditions of those pumps they all warned you they had lots of problems and weren't taken care of.  Good luck, I know exactly what you're talking about because I could not get the vector to work on some of those 34's. Let me know what the problem was I'm curious.

the vector system can be touchy boys.. my 61 has the vector.. not really a fan either i like the old school omnex box(the grey box)

but back to the problem at hand. everything works as in when in pto boom outriggers works? except the rpms?

nothing at all works, no boom , no outriggers , nothing hydraulic

ow wow well maybe that pluc thats unhooked or missing... is a proximity switch like the computer implies....

did you check the prox switch on the pto see if it missing has power or if the adjustment is out on some of the vectors if the prox is not adjusted properly it thinks the pto is not engaged therefore your have no functions

The Vector does not look at this prox for anything but RPM, yes you get this warning but everything should work, one of the latest versions of the software will kill the stroke limiter but that is it. Have you tried the local control or the cable remote.Does the radio turn on and is it sending a signal.The prox in question is on the front of the Stiebel box and reads 2 bolts that thread into the flange adapter. The Vector has no known issues and has been Schwings most reliable operating system to date.

I agree - check the sensor on the driveline that sends the RPM info to the computer.  Not sure on vector but if this was dirty, broken or out of adjustment on older models it would cause problems.

If the fault number is DO3L the problem is with the RPM sensor, bolts that trigger it, or possibly the D+ signal from the alternator. If you have more questions please call 888-schwing. 

was the prox switch . thanks everyone for your help
