Abstract
A set of elevators, preferably an elevator group, may include a number of elevators without counterweight which have a common connection to a power supply. The elevators may have a common control system which contains an instruction to prevent an elevator having stopped at a floor from being dispatched upwards if, of the elevator cars of the other elevators connected to the same power supply, more cars are moving upwards than are moving downwards at the instant and/or within a set period of time. A method for controlling a set of elevators without counterweight connected to a common power supply may include monitoring to establish whether, at the instant and/or within a set period of time, the number of upwards moving elevator cars of the elevators in the set is larger than the number of downwards moving elevator cars of the elevators in the set.

- 6. A method for controlling a set of elevators without counterweight connected to a common power supply, wherein in that monitoring is performed to establish whether, at the instant and/or within a set period of time, the number of upwards moving elevator cars of the elevators in the set is larger than the number of downwards moving elevator cars of the elevators in the set, and that, when the number of elevator cars moving upwards is larger than the number of elevator cars moving downwards, an elevator having stopped at a floor is prevented from being immediately dispatched in the upward direction.
