5.6 Limit switch connection
Different limit switch systems can be used with the TST FUxF door control system. The default
setting uses an absolute encoder as the limit switch. In addition, mechanical cam limit switches
may be used.
Compliance with the safety function in accordance with EN 12453:2017 requires the use of a
position encoder with PL "c", minimum cat. 2 in accordance with EN 13849-1.
For the connection of an absolute encoder to a TST FU3F we recommend to place a
split ferrite (black, Würth Number: 74271722S) around the wires of the absolute
encoder (terminal 33 – 36) as close as possible to the door controller around the
complete motor cable.
The black split ferrite is not included in the scope of delivery!
5.6.1 Absolute encoder TST PE or TST PE FSB with WICAB system
The absolute encoder TST PE is a single turn encoder. The driving shaft must not execute more
than a single revolution over the entire path of the door.
Absolute encoder TST PE FSB is equipped with the WICAB radio system. The WICAB system can
be employed to replace the spiral cable with a wireless link. For this purpose, a mobile unit TST
FSBM or TST FSAM must be mounted on the door leaf.
