Abstract: A maintenance system for monitoring a gate device includes the gate device having a gate guide, a gate segment which is movably supported in the gate guide, and a sensor which monitors a gate guiding quality. A method for monitoring the gate device includes the gate device having a gate guide, a gate segment which is movably supported in the gate guide, a sensor which monitors a gate guiding quality arranged at the gate segment, and a maintenance unit. The method includes, when a movement of the gate segment occurs, detecting a vibration value and/or an acceleration value of the gate segment via the sensor, and transmitting the vibration value and/or the acceleration value as maintenance data to the maintenance unit.

Abstract: A servicing and monitoring system for monitoring a gate member which is moved by a drive apparatus. The servicing and monitoring system includes a drive control unit which actuates the drive apparatus, a detection device which detects a gate status of the gate member, a first data connection which connects the drive control unit and the detection device and via which a status signal of the gate member is transmitted from the detection device to the drive control unit, and a data reading device which reads the status signal sent from the detection device to the drive control unit and which outputs an alarm signal depending on the status signal read by the data reading device.

Abstract: A maintenance system for a door arrangement. The door arrangement includes a door member and a drive unit configured to drive the door member. The maintenance system includes a control device comprising a motor control unit configured to control the drive unit and a non-temporary memory configured to store door data, a central maintenance data memory comprising maintenance data for at least one of configuring, monitoring and modifying the control device, a first bidirectional data connection, a second bidirectional data connection, and a mobile maintenance device. The door data is retrievable from the non-temporary memory. The mobile maintenance device is configured to be coupled to the non-temporary memory of the control device via the first bidirectional data connection to maintain the door arrangement, and to be directly or indirectly coupled to the central maintenance memory via the second bidirectional data connection.

Abstract: A reflective photo-electric sensing system includes a transmitter for the transmission of light and a reflector for reflecting the light. The reflector being positioned in a far field. A light channeling device receives reflected light from the far field or from a near field and channels the received reflected light to a near field receiver or a far field receiver dependent on an angle of the received reflected light. An electrical signal is generated at the near field receiver or the far field receiver. A controller evaluates the electrical signal of the near field receiver and the electrical signal of the far field receiver and generates an actuation signal dependent on the evaluation.
