    Abstract: The invention relates to an adjustment device (1) for controlling the electric drive (2) of an elevator in connection with a voltage reduction of the supplying network. The electric drive of an elevator comprises an electric motor (3) and a power supply apparatus (4) of the electric motor for adjusting the supply voltage of the electric motor. The adjustment device comprises means (5, 6, 7) for controlling the power supply apparatus (4) of the electric motor and also a speed regulator (8) for adjusting the speed of the electric motor. The adjustment device (1) is arranged to determine the output voltage (9) of the power supply apparatus of the electric motor in relation to the permitted maximum value of the output voltage, and the adjustment device (1) is arranged to interrupt the operation of the speed regulator (8) but to continue the operation of the power supply apparatus (4) of the electric motor when the output voltage (9) of the power supply apparatus of the electric motor reaches the permitted maximum value.

    Abstract: An elevator (1) comprises a control system (114) for monitoring the load of a car (102), which control system (114) is adapted to prevent the normal starting of the elevator (1), optionally also including relevelling, when there is an overload in the car (102). In the invention, the elevator (1) comprises at least one position measuring device, speed measuring device and/or movement measuring device (115) in order to determine the movement and/or position of the car (102), and the control system (114) of the elevator (1) is adapted to remove the prevention of normal starting when at least one said position measuring device, speed measuring device and/or movement measuring device (115) detects that the car (102) moved or is moving upwards in the elevator shaft (100). In the method, the control system (114) of the elevator (1) is used to determine the load situation of the car (102), including both the steps to prevent the normal starting of the elevator (1), optionally also including relevelling, when there is an overload in the car (102) and to open some of the machinery brakes (160, 162) and to keep the remaining machinery brakes (160, 162) closed in order to determine the load situation.
