Error 47 pump open

Hi we have this 24v Cat ep10 krt-pac serial etb10a 10205.
Throws error 47 saying pump open. The truck will drive and it will lift for a few seconds before throwing up the code and tripping out.

Pump motor is ok and cables all ok. Tried another battery to eliminate battery issue as the other day after coming off charge worked fine.for 1 day.

I would really appreciate some advice what else we could check as we have swapped the traction and hydraulic inverter accross to eliminate that.

My only concern is that both inverter say 48 whereas i have only seen inverters marked 48 on 48v trucks. This truck is 24 and i am sure thats wrong but Customer bought this truck as is and worked fine apparently.

If anyone can share a service manual or confirm the inverter query i have would really be appreciated.

Thanks

Hi

Yes its 24v definitely. We worked out what happened. At some point someone swapped the covers off the unit and mixed them up. The units are also 24v. After further investigation we found that these units are not interchangable between traction and lift.
The unit was internal faulty, which we have now repaired.

Thanks you for the reply.

Hello
are you sure it s 24V not 24 cells with 48 Volts
