Abstract
A safety apparatus for elevator apparatuses which can move a cab via a drive including a monitoring unit for monitoring at least one of the drive and/or the motor regulation system of the drive, a safety device having at least two sensors, which can be switched between at least two switching states depending on a state, in particular a closing state. In order to be able to reduce operating costs, at least one of the safety device and the monitoring unit includes a controller, which is designed to identify the respective switching states of the sensors, and to transmit at least one of data and monitoring signals to the monitoring unit.
Claims11
A safety apparatus for an elevator apparatus which can move a cab via a drive, comprising:
- a monitoring unit for monitoring at least one of the drive and the motor regulation system of the drive,
- a safety device having at least two sensors that are switched between at least two switching states depending on a state of the elevator apparatus, wherein at least one of the safety device and the monitoring unit comprises a controller that identifies the respective switching states of the sensors, and transmits at least one of data and monitoring signals to the monitoring unit, and
- the monitoring unit further comprises an interruption apparatus for interrupting the drive depending on at least one of the data and monitoring signals from the controller,
- wherein the sensors and the controller are connected in series.
