Otis Removed a hydraulic unit from service years ago ( Removed Power Feed,Sealed Doors, Removed pipe ect). We were hired to put it back in service and have found that Otis Stole the LRV microprocessor from behind the COP. We have other LRV boards but we need the Computer Chips that are used on the microprocessor.. Is there any work around for this?
PM me a picture of the board, I should have software and chips for it. The first LRV used a 8749 Micro 40 pin with the software programmed to the chip. I have those too.
The board you have pic's of is an LRV5 Otis board with U10 & U11 chips. Are you sure this is the correct board for the job? There are many vintages and wiring diagrams of LRV Series. Need to have the correct processor board for the job U10 is a 27C512 chip and U11 is a 27C64. Sent you a PM.
Just a question. In the State that I’m in, if you place an elevator back in service that has been decommissioned. The State will require it to comply with current code.
