New Lift presents the CBM 3

There is no stopping the trend to digitalisation and automation – and the lift sector is no exception to the rule. New Lift Steuerungsbau GmbH will be presenting an innovation at the interlift with its CBM 3 contactorless brake module.

“It not only enhances the safety and efficiency of lifts but also revolutionises their maintenance,” the company promised.
 The new module is a further development of the already established CBM 2 and features two central innovations: the integration of brake checker technology in cooperation with mayr and adjustment to the new standard requirements pursuant to the upcoming ISO 8100-1/2.

The CBM 2 is already in use as a solution for brake control in lifts. It permits continuous activation of up to two brake circuits with voltages of up to 40 to 207 V and currents of up to 6 ampere per circuit – and all this without a mechanical contactor and transformers.

A CANopen interface takes care of the parametrisation and real-time monitoring. But lift sector requirements are increasing: stricter safety standards for brake controls will become binding with ISO 8100-1/2.

This is where CBM 3 comes in. It takes on the functions of its predecessor and expands them with additional features. The new standard requirements are met by an integrated safety circuit with restart interlock in the event of fault detection in the controller.

In addition, mayr’s integrated brake checker technology can replace monitoring switches with an intelligent, sensorless analysis of the current and voltage.

Wear prediction


The system not only detects the operating status of the brake but also analyses complex matters such as switching times or coil resistance. As in all of the latest generation Mayr brakes, there is no need for a brake release monitoring switch. This resulted in greater reliability, less maintenance effort and a precise prediction of wear, the controller manufacturer declared.

Thanks to the operation without contactor, noise and mechanical error sources were eliminated while the CANopen interface permitted easy integration in existing controller systems. The continuous adjustment of brake release and locking voltages as well as the monitoring of all brake circuits for over- and undercurrent enhanced safety and flexibility, New Lift underlined.

Lower production costs


The CBM 3 is cheaper to produce compared to conventional solutions. There was also no expense for wiring and inspection of mechanical components, which accelerated start-up and reduced the maintenance effort, according to the manufacturer.
