I got an Otis GTS, after clearing an entrapment between floors. My 2nd and 3rd floor lost voltage. It’s a 10 story building. Elevator only moves on hoist way door bypass. I lose safeties and doors when I take it out. My TDS and BDS have 120VAC. And FDS pin 3( plug p28) has 120 but nothing on pin 4. I kill power and check continuity on 2nd floor door locks and got nothing. I’m thinking it’s a broker wire but it’s like 200 ft of wire up to the controller. Any workaround? I was thinking of jumping that door lock just to see if I get my safe 1 and safe 2 and GDS input on high and remove the jumper.
