The interior of the TS981 has been specially developed for placement in the plastic GfA housings with integrated up-stop-down controls in the lid (type: TS-A and TS-XL). The TS981 is a microprocessor control with many options such as traffic light control and smoke/heat extraction for pulse or dead man operation. The TS981 is suitable for 1- and 3-phase industrial door drives with digital limit switches. The parameters in the very extensive menu are easy to set using the programming switch (rotary/press) and the display. With optional modules, a lock function (type: SLF) and status reporting (type: SMF) can easily be implemented.
