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?
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.
