  • Page 10: Product Description

    Terminal box, NBS connection Motor TW63, horizontal The NBS emergency brake system that is mounted as an option on ThyssenKrupp elevator gears serves as an additional protection device against overspeed for the elevator car as it moves upwards. It complies with the applicable regulations of EN81.
  • Page 11 NBS emergency brake system after a preset delay time. Closing in the event of emergency stop or power failure: In all 3 cases, the drive brake and NBS emergency brake respond without a delay. (UCM – uncontrolled car movement complying with EN81-A3)
  • Page 12 If the installation is defective or without current, initiate rescue. To move the elevator car in order to achieve this, the NBS emergency brake must be put out of operation. Proceed as described in chapter 6.3 and comply with the specified safety instructions.
  • Page 13 • The operator must ensure that the setting of the air gap made at the plant is not changed, thus ensuring faultless release of the brake. • The NBS emergency brake system is intended for static application as a parking brake. Dynamic braking is restricted to emergency braking when the elevator is moving upwards.
  • Page 14 Indicator lamp +NBS-H77 does not light up. The power supply +NBS-G77.2 provides the control voltage of 24 V. The die 230V AC is provided as mains voltage at the input of the NBS control system terminal X2:L. This mains voltage also supplies the module from generation of the brake DC voltage G77.1 via make contacts of the NBS contactors.
  • Page 15 (safety circuit closed), a run can be initiated by the elevator control system. Initiation of a run is signalled by the elevator control system to the NBS emergency brake control system in that the elevator control system applies a voltage of 230 V~ to contactor coil +NBS-K77.3.
  • Page 16 The delay of the auxiliary switch block +NBS-K77.3, which can be set from 0.1 to 30 seconds, should be set in such a way that the NBS emergency brake only engages when the drive is at a standstill and the service brake firmly brakes the drive.

This electrically releases the NBS emergency brake. Run emergency rescue with manual release of the drive brake (same as for drives without NBS).
  • Page 18 After completion of the measures, the secure operating mode is to be established. The connection terminals in the control unit of the NBS emergency brake are to be bridged according to installation plan / wiring diagram / drawing.
