A method for performing a software update of a people conveyor component in a conveyor system includes downloading a software update from a remote update system based on a request from one or more of the remote update system, at least one conveyor component or the conveyor system such that the software update is downloaded as a background download without affecting an operation of the conveyor system.

An elevator includes a control system for monitoring the load of a car, which control system is adapted to prevent the normal starting of the elevator, optionally also including relevelling, when there is an overload in the car. The elevator includes at least one position measuring device, speed measuring device and/or movement measuring device in order to determine the movement and/or position of the car, and the control system of the elevator 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 detects that the car moved or is moving upwards in the elevator shaft. In the method, the control system of the elevator is used to determine the load situation of the car, including both the steps to prevent the normal starting of the elevator, optionally also including relevelling, when there is an overload in the car and to open some of the machinery brakes and to keep the remaining machinery brakes closed in order to determine the load situation.

Elevator car overload monitoring to prevent starting

A passenger conveyor may include a conveyor motor controlled by a conveyor control via a motor drive, the motor drive including a frequency converter with a rectifier bridge, an intermediate DC circuit and a converter bridge connected with the conveyor motor. The rectifier bridge is configured to be connected to mains via at least one relay, which relay is controlled by the conveyor control, the conveyor comprises a deep sleep mode, in which the frequency converter as well as at least a major part of conveyor control is switched off. The intermediate DC circuit forms the power supply for the conveyor control. During the activation of the deep sleep mode, the conveyor control is configured to open the relay, whereby at least one signal circuit of the conveyor is configured to remain powered at least during the deep sleep mode.

In a method for performing a balance check with an elevator, a power model of the elevator is established, including the motor power fed to the motor (P) and power parameters of the motor and the moved components in the hoistway (P, P, P, P, P), a test run of the elevator is made, mid motor power values for the up and down direction are determined, i.e. the power fed to the motor at the instant when the car is moving through the middle of the travelling path of the elevator in up and down direction with constant velocity, the difference between the mid power value in up and down direction is determined, the balancing weight difference is obtained from said mid power value difference. This method allows an easy determination of the elevator balance preferably in course of modernizations of an elevator system with a new elevator motor.

Method for determining the balancing weight difference in an elevator

The invention relates to a safety circuit of an elevator and also to a method for identifying a functional nonconformance of the safety circuit of an elevator. In the method a message is formed in node A, a testing field is added to the message for testing the operation of the safety circuit of an elevator, and the aforementioned message containing the testing field is sent from node A to the communications bus in the safety circuit of the elevator.

Safety circuit of an elevator, and method for identifying a functional nonconformance of a safety circuit of an elevator

The invention relates to a safety arrangement of an elevator system and to a method for ensuring safety in an elevator system. The safety arrangement comprises at least one mechanical stopping appliance and the control of the safety arrangement comprises at least one limit value that sets the speed, deceleration or permitted vertical distance from the door zone of the elevator car. In the method for ensuring safety in an elevator system at least one mechanical stopping appliance is fitted to the safety arrangement of the elevator system and at least one limit value that sets the speed, deceleration or permitted vertical distance from the door zone of the elevator car is set for the control of the safety arrangement.

Supplemental elevator safety system

The invention relates to an arrangement and a method for limiting the input power of a power supply appliance () fitted between a power source () and a load (). The arrangement according to the invention comprises a power supply appliance () fitted between a power source () and the load to be supplied (), which power supply appliance () is fitted to limit its input power on the basis of the status of the aforementioned power source ().

Limitation of the loading of a power source

The invention relates to an elevator system and also to a method for detaching an elevator car and/or a counterweight from a safety gear. In the method torque pulses are produced with the hoisting machine of an elevator, for detaching a gripped stuck elevator car and/or a gripped stuck counterweight.

Method in connection with an elevator system having torque impulses and an elevator system thereof

An elevator system where control appliances of the elevator system are fitted to communicate between themselves is described herein. The elevator system has a control arrangement for placing at least one control appliance into standby mode or for terminating the standby mode. The control arrangement is fitted to set the standby mode on the basis of at least one activation signal, as well as to send a control signal of the standby mode to at least one control appliance of the elevator system. Associated methods for fitting a standby mode into an elevator system are also described herein.

Controlling an elevator with a standby mode

The invention relates to a procedure and an apparatus for analyzing elevator functions and detecting deviating functions. By monitoring signals associated with traffic events in the elevator system, an analyzer connected to the elevator learns the normal operation of each elevator independently. Signals occurring during operation are compared with the information thus acquired and a failure alarm is produced or the information is altered to make it accord with the new, changed situation.
