When expanding the FST-2 with a GST circuit board, the FST-2 becomes a FST-2 GROUP.

The GST group circuit board is a powerful computer especially developed for the FST-2 lift control system. A FST-2 GROUP with a GST can effortlessly control groups with up to 8 lifts.


Of course the GST is compatible with both FST generations.


With the LON field bus connection to the FST-2 controller, the GST can detect all activities in the group directly and can apply and process this information thanks to its 32-bit processor.


For systems requiring the highest state of availability, a multiple redundant group control option can be integrated by installing at least two GST circuit boards in a group. In the case of a primary GST circuit board system failure, one of the secondary GST boards seamlessly takes over all control functions.
