What is the new GST update

GST-XT

The GST-XT group control board also makes optimal use of the LON technology that is used in the FST controls. Using this technology, the GST-XT has knowledge of all activities on the LON bus and thus of all measured and actual characteristics of all elevator systems participating in group operation. Thanks to its 32-bit computing power, the GST-XT can intelligently process this information and thus guarantee efficient traffic management for all group participants.

A mixture of automatic and configurable functions gives the GST-XT a unique degree of flexibility, even for the most demanding installations.

The incoming calls from the shaft bus are processed by the GST-XT and calculated using a large number of criteria in the group algorithm. On the basis of this group algorithm, the GST-XT then distributes the calls to the individual FST controls within the group.

In the unlikely event of a GST-XT failure, an emergency program within each FST controller takes over the movement commands. For systems that require a high level of operational readiness, a multiple redundant group control option can be integrated by installing at least two GST-XT group control boards within the group. In the event of a system failure of the primary GST-XT, one of the secondary GST-XT takes over the group control function.

Copies of the parameter sets of all connected FST controls are stored in the GST-XT memory. This enables the GST-XT to incorporate information about door times, travel curves, drive calibration data and shaft dimensions of the individual controls into the group algorithm.

If control parameters are changed in one of the FST menus, this is automatically recognized by the GST-XT and a copy of the changed parameter set is stored in the memory.

If the date and time settings are changed on a controller, all controllers in the group adopt the new time settings synchronously.
