A switch assembly including a switch and a drive system for the switch. The drive system includes a motor for driving the switch, a control device with a power section for supplying power to the motor, a controller for initiating a switching operation of the switch by control of the power section, and a protection circuit. The protection circuit is configured to detect a first error signal via a state contact of the controller in the event of a malfunction of the controller, detect a second error signal via a state contact of the power section in the event of a malfunction of the power section, and initiate a safety measure depending on the first and the second error signal. The control device is configured to activate the protection circuit prior to the switching operation being initiated and to deactivate it following successful execution of the switching operation.

Switch assembly and method for safely operating a switch assembly

A switch assembly has a switch; and a servo drive system for the switch. The servo drive system includes: a motor configured to drive the switch; a power section configured to supply power to the motor; and a control unit configured to control the power section depending on at least one desired value. The control unit is configured to identify the presence of at least one safety-relevant event and, in the case of the safety-relevant event, to transmit at least one control signal to the power section. The power section is configured to initiate or carry out at least one safety measure depending on the control signal.

Switch assembly with drive system, and method for safely operating a switch assembly

A method carries out a switchover of a first switch or at least one second switch for equipment. The method includes receiving, by a controller, a switching signal; selecting, by the controller, the first switch or at least the second switch for switchover on the basis of the switching signal; querying, by the controller, at least one parameter of the first switch or the at least second switch; checking a locking condition on the basis of the at least one queried parameter for the first switch or a locking condition for the at least second switch; and carrying out the switchover by the selected first switch or the at least second switch based upon the corresponding locking condition being met.

Method for carrying out a switchover of at least two switching means for equipment, and drive system for at least two switching means in equipment

A drive system drives a switch. The drive system includes: a drive shaft connecting the drive system to the switch; a motor configured to drive the drive shaft; a feedback system; and a controller. The feedback system is configured to: determine at least one value for a position of the drive shaft; and generate a feedback signal based on the at least one value. The controller acts on an operation of the motor depending on the feedback signal.
