anyone have any experience with a 20-003 error?
new selector board, new clc board, new tape guides, power supplies all ok, switch tree contacts have all been gone thru, car intermittently will leave bottom floor, and about 1/4 of the way up, the car drops the call, logs 20-003 error, levels back down to bottom and you press call again, and it takes off and runs. car is a 2 stop also checked magnets with template and all is good there car will run sometimes a hour or so with no trouble and then do it one time. thought i would run it buy you guys to see if anyone has seen this. thanks

well went back today, did not have switches so i decided to experiment, i jumped the uts and tsl switches to eliminate switches, problem still occurred. pulled the switch tree off, and went thru all switches and wiring no problems found, put back and problem still occurred, installed new sensor card, same thing. now starting to get frustrated, when it does fail, i can here the car floor passing gong come on just as the car leaves, so I'm thinking to myself, it seems like the selector actually thinks it is further then it is, like it is counting to quickly. so i decide to recheck the first floor level magnet, and parity magnet for the umpteenth time. this time i flip both magnets upside down from there original position, realign again, and put back in service ran the car continually for nearly 3 hours and now the car will not fail. now I'm thinking the elevator gods are screwing with me, it just can't be, the car is going to fail, but it is still running. packed up my tools, left with my tail between my arse, feeling a few years older, and not very much wiser. will keep you posted
