Lets look at the symptoms- Report that comes in to me.....Elevator at lobby (lowest landing) with hall calls all fired, door open, low oil board low, and elevator will not run. If the car is on LOT, the doors would be closed and there would be no hall calls entered. Throw the cat into LOT and see if this is the case. If so, then you are probably looking at a (cannot close the doors) problem. When you say- hall calls all fired- does this mean also the 1st floor up fired? Are there any car calls fired? Is the 1st floor car call fired? Do hall calls cancel when you reach the DOL or when you arrive at the floor? What bypasses the DCL to keep power on the operator during a run? Could DCL be not making? Why does MLR release the car? There is no mention of car position, above the floor, below the floor, or at floor.
What door operator is this using? Is this only after a weekend or does it happen during the week? What kind of building? Could be a problem in the CS circuit locking it up.
