It’s probably under job requirements sub menu off block select adjustments.

So Maintentaice in the building had been recycling power every time b4 I got there until today. Now I have a 2nd code. 1074 jack resync low pressure. I removed the buffer springs to see if that will stop it from happening for now. Magnets on back of tape are fine.

You need to do an FJR to make sure the car can do a proper resync. You shouldn’t be getting a low pressure fault on a resync unless something is wrong.

Fault code is 1074. In manual it says pressure switch active .
On the UIT is says 1074 jack resync low pressure shut down .
I manually re sync it and it leveled up fine after

What can cause that? The car binding during sync ? Bad synchronizing valves?

It seems the problem is my jack low pressure switch .. I wonder if my up leveling strainer is causing this.

Update. Every time car gets sunk in pit i get 24v to prsw . Causing shutdown. Car still levels fine after sync and shuts down level at bottom terminal landing... car passes standing test ...There is no visible leaks anywhere. System is dry .. my car is not bottoming out .. has anybody else had this problem ?

Depending on software, older versions would spit the 1074 out, as a proper resync does allow PRSW to come active. IDWT has the right idea, do a FJR on a clean slate and see what faults pop up. The 1074 could just be a ghost, and not part of your problems. While resyncing, verify you do not come off NTSB or DLT. That's where my money is right now, as while syncing, you lose placement, car won't make an effort to "find" itself, but on a power cycle it will...
As for the original door issue, potentially car could have been racking during the resync, allowing a car door or hoistway door to open, causing that original 1110. Again easy to duplicate by using the FJR.

Did a FJR and got 1074 and 1110 .. also turned power off and manually lowered car into pit. Turned power on and got same results. 1074 and 1110 as car leveled up out of pit. With prsw jumped out it does not give me any faults during resync forced or manually lowered

You do have BLO in your IO map right? It should be port 8 bit 2.

Ok. Thanks dirt. I wonder how this car ran for a year with no shutdowns

It shouldn’t need it since it’s not actually doing anything but I found an old note that this fixed some odd syncing problems. It’s possible this was fixed with a software update too. What version is the software?
